I Replaced GitHub Copilot with This Free Open Source Tool for My AI Coding Workflow

I’ve been building and automating SaaS tools as a solopreneur for the past three years. One of the biggest expenses in my stack was GitHub Copilot — $10 per month. It’s useful, but I started wondering: is there a free, open-source alternative that actually works for solo developers shipping real products?

After testing a dozen tools, I found one that not only replaced Copilot but improved my workflow. It’s called Cursor, and I’ve used it daily for the past six months to build two micro-SaaS products that now bring in $1,200/month combined.

If you're a solopreneur or small business owner using AI to automate tasks, write code, or launch products, this tool could save you money and boost your output. Let me walk you through how it works, why I switched, and how you can set it up in under 10 minutes.

Why I Left GitHub Copilot

Copilot is solid. It suggests code as I type, which speeds up development. But at $10/month, it’s a recurring cost that adds up — especially when you’re bootstrapping.

More importantly, Copilot doesn’t let me customize the model or control where my code goes. It sends snippets to Microsoft’s servers. For a solo founder working on proprietary logic or customer-facing automation, that’s a privacy red flag.

I also noticed Copilot struggles with context across files. It’s great for line-by-line suggestions but often misses the bigger picture of my app’s architecture. That led to bugs and time wasted fixing inconsistent logic.

I wanted something:

• Free and open source
• Runs locally (private code stays private)
• Understands full project context
• Supports AI chat inside the editor

That’s when I found Cursor.

What Cursor Is (and How I Use It)

Cursor is an AI-first code editor built for developers who want full control. It looks like VS Code but has AI built into the core. The best part? The local model version is free and runs on your machine.

I downloaded Cursor from cursor.sh and installed it in two minutes. I enabled the local model (via Ollama) which runs a 7B-parameter LLM on my Mac M1. No cloud calls. No data leaks.

Here’s how I use it in my daily workflow:

• Writing functions: I highlight a comment like “// calculate monthly revenue from Stripe events” and press Cmd+K. Cursor writes the function in Python using my actual Stripe webhook structure.
• Debugging errors: I paste a traceback into the AI chat and ask, “Why is this failing?” It reads my code files and gives a fix tailored to my app.
• Refactoring: I asked it to convert a Flask API to FastAPI. It updated 5 files, kept the endpoints the same, and improved error handling.

Last week, I built a customer onboarding bot in 90 minutes using Cursor. Without it, that would’ve taken me half a day. That’s real time saved — and time is money when you’re solo.

How to Set Up Cursor for Free (Step-by-Step)

You don’t need technical wizardry to run this. Here’s how I set it up:

1. Download Cursor from cursor.sh (free, no credit card).
2. Install Ollama — a tool that runs local LLMs. Takes one command in Terminal: brew install ollama.
3. Run ollama pull codellama:7b to download a lightweight coding model.
4. In Cursor, go to Settings > Model and select “Ollama” and “codellama:7b”.
5. Open your project folder. Now you can use Cmd+L to chat with your entire codebase.

It runs slower than Copilot on complex tasks — about 10-15 seconds for longer functions. But the trade-off is privacy and $0/month cost. For solopreneurs, that’s worth it.

If you have a stronger machine, try codellama:13b or deepseek-coder:6.7b — they’re smarter and faster.

How much does Cursor cost?

Cursor’s core editor and local model support are completely free. You can use it with Ollama at no cost.

They offer a paid cloud version with stronger models (like GPT-4-level) for $20/month, but I haven’t needed it. The local setup handles 95% of my coding tasks.

Is Cursor worth it for solo operators?

Yes — especially if you:

• Build tools or automate workflows
• Want to reduce SaaS subscription costs
• Value code privacy (no sending snippets to third parties)
• Work on side projects or micro-SaaS apps

I’ve tested it on Python, JavaScript, and SQL scripts. It performs best with clear comments and well-named functions. The more context you give, the better it responds.

One caveat: it’s not perfect. I still review every AI-generated block. But it cuts my coding time in half, and that’s let me launch faster.

Last month, I used Cursor to automate a client’s invoice processing system. It saved them 10 hours/week. I charged $800 for the build. That’s a 75% profit margin, mostly because the tool helped me code fast and stay within my budget.

Final Thoughts: Cut the Copilot Bill, Keep the Speed

I’m not saying Cursor is better than Copilot in every way. But for solopreneurs, it’s a smarter fit. It’s free, private, and powerful enough to ship real products.

You don’t need enterprise-grade AI to automate tasks or build small tools. You need something affordable, reliable, and under your control. Cursor delivers that.

If you’re spending $10+ a month on coding assistants and working solo, you’re overpaying. Switch to Cursor, keep the savings, and reinvest in your business.
