Free Cursor Alternative: Cline + DeepSeek Setup Guide (Monthly Cost Under $1)

When last month’s credit card statement arrived, I stared at that $20 Cursor Pro charge for a while. It’s not that I couldn’t afford it, but I suddenly realized—that’s $240 per year, roughly 1,700 RMB. As an indie developer, every monthly recurring expense feels like a noose around the neck.
That evening I started digging through tech communities, looking for cheaper alternatives. The name DeepSeek kept popping up. People were saying it achieved a 71.6% success rate on SWE-bench, slightly better than Claude 4’s 70.6%. The key was the price—only 1 RMB per million input tokens, 1/68th the cost of Claude.
My first reaction was: this cheap, can it be reliable?
After trying it for a week, I canceled my Cursor Pro subscription.
Why Choose Cline + DeepSeek?
Bottom line first: If you can accept 80% of Cursor Pro’s experience, your monthly cost can drop from $20 to under $1.
I made a comparison table of three mainstream solutions:
| Tool | Monthly | Yearly | Main Features |
|---|---|---|---|
| Cursor Pro | $20 (¥144) | $240 (¥1,728) | AI completion, Agent mode, unlimited chat |
| GitHub Copilot | $10 (¥72) | $120 (¥864) | Code completion, chat |
| Cline + DeepSeek | ¥1-5 ($0.14-0.70) | ¥12-60 ($1.70-8.40) | Agent mode, file operations, terminal execution |
Seeing this price difference, you might think: such a huge gap, the features must be way worse, right?
Honestly, I thought so too at first. But after actually using it, Cline can do way more than I expected. It’s not just simple code completion—it can read your project files, modify code, execute terminal commands, and even connect to databases through MCP protocol. Most things Cursor Pro can do, Cline can handle too.
What’s the real difference?
Completion speed. Cursor’s completion is nearly instant, while Cline requires manual invocation (Ctrl+Shift+L). It’s definitely not as smooth as Cursor, but what you get in return is complete cost control—when you’re not using it, you don’t pay a cent.
Model performance? This is where I was most pleasantly surprised. DeepSeek V3’s performance on coding tasks genuinely matches Claude. I had it refactor a 3,000-line React component, splitting logic, optimizing performance, adding TypeScript types—all in one go. The cost? About 3 cents.
There’s another hidden advantage: Cline is open source. This means you can switch models anytime—use Claude, GPT-4, local Ollama, or even write your own MCP tools to extend functionality. Cursor locks you into their ecosystem; Cline gives you complete freedom.
Instead of talking more, let’s look at real data. I used Cline + DeepSeek to write a complete Express API project (about 50 files, 5,000 lines of code), total cost: $0.45. The same project with Cursor Pro, even if I only used it for one day, would charge me the full monthly $20.
5-Minute Installation and Configuration of Cline
What I fear most about configuration is spending hours and still not getting it to work. Good news is, installing Cline is way simpler than I imagined.
Step 1: Install the Extension
Open VSCode, click the extensions icon on the left (or press Ctrl+Shift+X), type “Cline” in the search box. The one with the blue icon is it—click Install. After installation, restart VSCode, and you’ll see a Cline icon in the left sidebar.
Click it, you’ll see a chat interface with a big “Configure API” button. Don’t rush—go get your API Key first.
Step 2: Get API Key
This is the most critical step, and where I hit the most snags.
DeepSeek’s official website does provide an API, but the problem is—it requires an overseas credit card, and sometimes gets blocked by the Great Firewall. I tried for two days without success and almost gave up. Later I saw someone on V2EX recommend APIYI, a proxy platform that supports Alipay, and I got it done in ten minutes.
Method 1: APIYI (Recommended)
- Visit apiyi.com
- Register an account (email is fine)
- Top up (minimum 10 RMB, I topped up 20 and still have 15 left)
- Create a new Key in the “API Keys” page
- Copy the
sk-prefixed key
Method 2: SiliconFlow (Fast in China)
- Open siliconflow.cn
- Login with GitHub
- Free quota each month (about 2 million tokens)
- Create API Key
I use both now. Normally use APIYI, occasionally switch to SiliconFlow when I hit 429 rate limit errors.
Step 3: Connect the API
Back to VSCode’s Cline panel, click “Configure API”. You’ll see a bunch of options, don’t panic:
- API Provider - Select “OpenAI Compatible” (don’t select OpenAI, DeepSeek is not OpenAI)
- Model - Manually enter
deepseek-chat(this is the V3 model name) - Base URL - Fill in the corresponding address below:
- For APIYI:
https://vip.apiyi.com/v1 - For SiliconFlow:
https://api.siliconflow.cn/v1
- For APIYI:
- API Key - Paste the key you just copied
Save. Then ask something random in the chat box, like “Hello”. If Cline responds, congratulations, configuration successful.
If you get “Invalid API Key” error—check if the Key was copied completely, with no extra spaces before or after. If you get “Connection failed”—probably the Base URL was filled incorrectly, double-check it carefully.
The whole process took me half an hour the first time (because I hit many pitfalls), but only 5 minutes the second time when setting it up for a friend. If you follow these steps, it should be quick.
Hands-On: Let Cline Help You Write Code
Once configured, it’s time to witness the magic.
Basic Operation: First Task
Press Ctrl+Shift+L (Cmd+Shift+L on Mac) to invoke Cline. The first time I tried, I just threw out: “Help me create a React Todo component, needs to support add, delete, and mark complete.”
Cline thought for a few seconds, then started outputting code. It doesn’t just give you a code snippet to copy-paste—it tells you: “I’m going to create src/components/TodoList.jsx, with the following features…” then lists out a detailed implementation plan.
After reading the plan, there are two buttons below: Approve and Reject. I clicked Approve.
What happened next kind of shocked me. Cline created the file itself, wrote the code, and even created a matching CSS file along the way. The whole process took about 20 seconds, and a complete Todo component appeared in my project.
Cost? About 0.7 cents.
Advanced Usage: @-mentions
After using it for a few days, I discovered Cline’s real power lies in its context understanding.
For example, if I want it to fix a bug in a specific file, no need to copy-paste the code to it, just type:
@src/utils/validation.js This file's email validation regex has issues, it doesn't support .co domainsCline will automatically read that file, find the problem, then provide a fix.
There’s an even cooler operation—referencing entire folders:
@src/components/ Convert all components in this folder to TypeScriptIt will analyze, convert, and add type definitions file by file. I tried it once—15 .jsx files all converted to .tsx, took only 5 minutes.
Other useful mentions:
@problems- Let Cline see all errors and warnings shown in VSCode@url- Let Cline read web content (like API docs)@terminal- Let Cline execute terminal commands
Real Case: Refactoring a Backend Project
Last week I took over an old project, an Express API with messy code structure. All routes piled into one 500-line file, no error handling whatsoever, database queries written directly in controllers.
I tried having Cline help refactor:
@server.js This file is too messy, help me do these things:
1. Split routes into routes/ folder
2. Separate controller and service layers
3. Add unified error handling middleware
4. Extract database queries into models/Cline spent about 2 minutes analyzing the code, then gave a detailed refactoring plan. It listed 12 files to create, each file’s responsibility, and migration steps.
I clicked Approve.
Over the next 5 minutes, Cline automatically created the new file structure, migrated all code, added error handling, and even wrote a few utility functions. I just needed to confirm before each operation to make sure the direction was right.
If I had done this entire refactoring by hand, it would’ve taken at least two days. How much time did Cline save me? Conservative estimate: 10 hours. Cost? $0.17.
Pitfall Warnings
Cline isn’t omnipotent—I’ve hit a few snags:
Too much context causes lag: Don’t
@folderthe entire project at once, especially those with thousands of files. Cline will try to read all files, and your API quota will burn instantly.Requirements must be clear: The more specific, the better. Don’t say “optimize this code,” say “this function’s time complexity is too high, optimize using a hash table.”
Review before approving: Cline sometimes misunderstands your intent. Check the plan carefully after seeing it, don’t blindly click Approve. I once didn’t look carefully and had it delete the entire database migration script.
Money-Saving Tips and Best Practices
Honestly, when I first started using Cline, I had zero cost awareness. Asking questions randomly, constantly @foldering entire projects, having it regenerate code repeatedly—the first week I burned through $1.12.
Later I started figuring out how to control costs and summarized a few money-saving techniques.
Tip 1: Precise Context Usage
This is the most critical point. Cline charges by tokens—the larger the context you give it, the more it costs.
For example, I wanted Cline to modify a component’s styles. Initially I’d do this:
@src/ Change all component button colors to blueCline would read all files under src/, potentially hundreds. Even if only 3 files needed modification, it had to analyze all files first. This one conversation consumed 50,000 input tokens alone, costing $0.07.
Later I got smarter:
@src/components/Button.jsx @src/components/Header.jsx Change button colors in these two files to blueOnly reference the needed files. This time only consumed 3,000 tokens, cost $0.004.
16 times difference.
Tip 2: Tiered Model Usage
DeepSeek has two main models: V3 and R1.
V3 is cheap and fast, suitable for daily coding. R1 is pricier but stronger in reasoning, suitable for complex problems. My strategy is:
- Writing new features, fixing small bugs → use V3
- Code review, architecture design, performance optimization → use R1
- Writing docs, comments → use V3
Most of the time V3 is enough. Only switch to R1 when encountering truly complex logic. This way monthly cost can be controlled under $0.42.
Want to save even more? You can configure multiple models in Cline settings—simple tasks can even use DeepSeek Lite (cheaper) or local Ollama (completely free but slow).
Tip 3: Use Checkpoints Wisely
Cline has a great feature called Checkpoints. After each task completion, click the bookmark icon in the upper right to save the current state.
Why use this?
Once I had Cline refactor a module, and midway it suddenly misunderstood my intent and modified a bunch of files incorrectly. I could only revert them one by one, wasting half an hour and several API calls.
If I had created a Checkpoint beforehand, I could’ve just clicked to restore. One second, zero cost.
Now my habit is: save a Checkpoint after completing each major feature. This way even if Cline messes up, I can instantly return to a safe state.
Tip 4: Batch Tasks in One Request
Don’t do this:
First time: Create a login form
Second time: Add form validation
Third time: Connect to backend API
Fourth time: Add error messagesEach conversation has a base cost. Should say everything at once:
Create a login form, needs:
1. Email and password input fields
2. Frontend validation (email format, password length)
3. Call /api/login endpoint
4. Error messages and loading stateCline will complete all features at once. What you save isn’t just cost, but also time.
Best Practice: Set Budget Alerts
In APIYI or SiliconFlow account settings, you can set monthly budget limits. For example, I set mine to 10 RMB—it emails me when exceeding 8 RMB, and automatically stops service when exceeding 10 RMB.
This way even if you accidentally run a huge task one day, it won’t cause a billing explosion.
My Real Usage Data
Finally, sharing my actual spending this month:
- Wrote 3 new features (frontend and backend combined about 8,000 lines of code)
- Refactored 2 old projects
- Fixed countless small bugs
- Had Cline help write comments and docs
Total spend: $0.60.
With Cursor Pro, that would be $20. Saved 97%.
Advanced: Build Your AI Coding Workflow
After using Cline for a month, I started thinking: how do I truly integrate it into my daily development process?
Multi-Model Combination Strategy
This is my current model configuration:
Primary Model - DeepSeek V3
- Use: Daily coding, rapid iteration, writing unit tests
- Advantage: Cheap, fast, good enough
- Covers 80% of my use cases
Secondary Model - DeepSeek R1
- Use: Code review, complex algorithms, architecture design
- Advantage: Strong reasoning ability, can find deep issues
- Covers 15% of my use cases
Occasional Use - Claude Sonnet
- Use: Writing technical docs, complex business logic sorting
- Advantage: Strong language ability, good comprehension
- Covers 5% of my use cases
Switching models is simple—click the model name in the upper right of the Cline panel to switch between different models. My habit is: use V3 to quickly implement features, then have R1 do a code review to find potential issues.
MCP Tool Extensions
This is Cline’s most powerful but least known feature.
MCP (Model Context Protocol) allows you to add custom tools to Cline. For example:
- Let Cline query databases directly
- Let Cline read requirements from Jira
- Let Cline access your knowledge base
I configured a filesystem MCP server myself, allowing Cline to search for specific code patterns in the project. For example: “Find all API calls without error handling,” Cline will automatically scan the entire project and list problematic code.
Configuring MCP requires some technical background, but the official docs are very clear. If you want to dive deeper into Cline, I highly recommend studying it.
Integration with Other Tools
Cline isn’t meant to replace all tools, but to be part of your toolchain.
My current setup:
GitHub Copilot + Cline = Completion + Agent dual boost
- Copilot handles real-time completion while writing code
- Cline handles complex tasks and refactoring
ESLint/Prettier + Cline = Code quality assurance
- Let Cline write code first
- Then ESLint checks for issues
- Then have Cline fix based on
@problems
Git + Cline = Smart commit messages
- I have Cline look at diffs and generate commit messages
- Input:
@terminal git diffthen say “write a commit message” - Cline analyzes changes and generates standardized commit messages
My Actual Workflow
Sharing my typical development process now:
- Requirements Analysis - Have Cline R1 read requirements docs, generate technical plan
- Build Architecture - Have Cline V3 create project structure and base files
- Feature Development - Write core logic myself, Cline writes utility functions and boilerplate code
- Code Review - Have Cline R1 check code, suggest improvements
- Write Tests - Have Cline V3 generate unit tests
- Write Docs - Have Cline generate API docs and comments
Throughout this process, Cline saves me at least 40% of the time. And because the cost is low, I don’t worry about “is this task worth using AI”—it’s just a few cents anyway, just use it.
Migrating from Cursor?
If you’re currently using Cursor Pro and want to try Cline, here’s a migration checklist:
✅ Cursor’s smart completion → Replace with GitHub Copilot
✅ Cursor’s Agent mode → Cline fully supports
✅ Cursor’s @-mentions → Cline has a more powerful implementation
✅ Cursor’s project indexing → Cline implements via MCP
The only thing missing is Cursor’s real-time completion experience. But honestly, after getting used to manually invoking Cline, I actually find this more controllable.
Summary
Back to the original question: Is Cursor Pro worth $20 per month?
For some people, yes. If you work at a big company with reimbursement, or your project revenue is high enough, Cursor Pro’s smooth experience is indeed worth it.
But for indie developers like me, students, or junior programmers—Cline + DeepSeek is a perfect solution.
This past month, I used Cline to complete:
- 3 complete projects (frontend and backend combined 20,000 lines of code)
- Refactored 5 old projects
- Fixed countless bugs
- Wrote tons of unit tests and docs
Total cost? $0.60.
I’m not saying Cline is perfect. Its completion isn’t as real-time as Cursor’s, it occasionally misunderstands your intent, and configuration requires a bit of technical threshold. But these minor shortcomings, compared to the $240 saved per year, really aren’t much.
Open VSCode now, search for Cline, and give it a try. Configuration only takes 5 minutes anyway, you can uninstall anytime if unsatisfied. But I bet after trying it, you’ll likely do the same as me—cancel your Cursor Pro subscription.
One last thing: The core of AI coding tools isn’t the tool itself, but how you use it. Cursor, Cline, GitHub Copilot are just different choices. Finding what suits you is most important.
By the way, if you encounter problems during configuration, feel free to leave comments. I’ll try to help answer. I’d also love to hear about your Cline experience and tips—might learn something new.

1. API Provider: Select "OpenAI Compatible" (don't select OpenAI)
2. Model: Manually enter deepseek-chat (this is V3 model)
3. Base URL: Fill according to platform
• APIYI: https://vip.apiyi.com/v1
• SiliconFlow: https://api.siliconflow.cn/v1
4. API Key: Paste the key you just copied
Important notes:
• No spaces before or after key
• Base URL must completely include /v1 suffix
• Click save after configuration
Test connection: Type "Hello" in chat box, if Cline responds normally, configuration successful. - 4
Step4: First Use Test
Verify if Cline is working properly:
Basic test:
• Press Ctrl+Shift+L (Mac use Cmd+Shift+L) to invoke Cline
• Input simple task: "Create an index.html file with Hello World"
• Review the plan Cline provides, click Approve
• Observe Cline automatically creating file
Advanced test:
• Try @-mentions feature: @src/filename
• Test terminal commands: Have Cline execute npm install
• Verify file reading: Have Cline analyze an existing file
If all work normally, configuration is completely successful.
FAQ
Why not register API directly on DeepSeek official website?
• Requires overseas credit card for top-up (domestic UnionPay cards not supported)
• Access may be unstable, some regions get blocked
Recommend using domestic proxy platforms like APIYI or SiliconFlow:
• Support Alipay, WeChat Pay
• Faster and more stable access
• Price is almost the same (APIYI is even cheaper)
• Chinese customer support available
I tried registering directly on DeepSeek official website myself, struggled for two days without success, ended up using proxy platform.
Will Cline suddenly increase prices like Cursor did?
Even if DeepSeek raises prices, you have other options:
• Switch to other cheap models (like Tongyi Qianwen, Zhipu GLM)
• Use local Ollama (completely free but slower)
• Switch to Claude, GPT-4 (expensive but good performance)
This is the advantage of open-source tools—you're not locked to one vendor, can switch anytime. Cursor is closed-source, you can only use their models and pricing.
What to do when getting Invalid API Key error during configuration?
1. Check if key is complete: starts with sk-, no extra spaces
2. Confirm Base URL is correct:
• APIYI use https://vip.apiyi.com/v1
• SiliconFlow use https://api.siliconflow.cn/v1
3. Verify API Provider selected "OpenAI Compatible" (not OpenAI)
4. Confirm key is active on platform (some platforms require top-up before activation)
If still doesn't work, try creating a new API Key—sometimes it's the key itself having issues.
How is the monthly $1 cost calculated?
Consumption statistics:
• Wrote 3 new features (about 8,000 lines of code)
• Refactored 2 old projects
• Daily bug fixes, code optimization
• Wrote unit tests and comments
Actual spend: $0.60
Cost control tips:
• Precise context usage (only @ needed files)
• 80% tasks use V3, 20% complex tasks use R1
• Batch tasks in one request, reduce conversation count
• Avoid @entire large folders
If you're a heavy user, might reach $1.12-1.40. But compared to Cursor Pro's $20, still saves 93%+.
Can Cline completely replace Cursor Pro?
What Cline can do:
• Agent mode (auto create files, execute commands)
• @-mentions (reference files, URLs, terminal)
• Code refactoring and optimization
• Extend functionality via MCP
Where Cline is inferior to Cursor:
• No real-time completion (requires manual invocation)
• Initial configuration requires technical threshold
• UI not as polished as Cursor
My suggestion:
• If you care about cost, use Cline (save 97% cost)
• If you pursue ultimate experience and money isn't an issue, use Cursor
• Can also combine both: Copilot for completion, Cline for Agent
Try for a week before deciding, Cline configuration only takes 5 minutes anyway, can uninstall anytime if unsatisfied.
What to do when context too large causes cost explosion?
Avoid doing this:
• ❌ @src/ reference entire source folder
• ❌ @node_modules/ reference dependencies folder
• ❌ Have Cline analyze large files with thousands of lines
Correct approach:
• ✅ Precise reference: @src/components/Button.jsx
• ✅ Multiple files: @file1.js @file2.js (only reference what's needed)
• ✅ Split large files: Have Cline locate problem area first, then modify specifically
Budget protection:
• Set monthly budget limit in APIYI/SiliconFlow
• Service automatically stops when exceeding threshold
• I set 10 RMB limit, email reminder at 8 RMB
Remember: Cline charges by tokens, smaller context saves more money. Difference can reach 16x or more.
Can I configure multiple AI models simultaneously?
Configuration method:
• Click model name in upper right of Cline panel
• Select "Add Model"
• Configure new API following same steps (Provider, Base URL, Key)
My multi-model strategy:
• DeepSeek V3: Daily coding (80% scenarios, cheapest)
• DeepSeek R1: Complex reasoning (15% scenarios, pricier but stronger)
• Claude Sonnet: Writing docs (5% scenarios, good language ability)
• Local Ollama: Offline testing (free but slow)
Switching is simple, just click model name to select. Use different models for different tasks, ensuring quality while controlling costs.
