Default recommendation
Start with Cursor Free for the best free editor experience and keep GitHub Copilot Free as the VS Code and JetBrains backup. Use the Gemini API free tier for anything you build, and move to DeepSeek V4.1 Flash at $0.30 in / $1.20 out per 1M tokens (peak; half off-peak) when a free limit blocks you.
Cursor Free
2,000 completions and a monthly chat allowance with access to current frontier models in an AI-native editor. Better multi-file context than any other free coding tool.

Frequently Asked Questions
What is the best completely free AI coding tool?
Cursor Free for the editor experience and codebase context; GitHub Copilot Free for VS Code and JetBrains users who want GitHub integration. Both are $0.
Is Cursor Free enough for professional development?
For part-time or hobby work, often yes. Full-time developers usually exhaust the 2,000 completions within two or three weeks, which is the signal to pay: Cursor Plus at $8 on Cursor's own models, or Premium at $30 plus metered use for Claude and GPT.
Is GitHub Copilot better than Cursor for free users?
Cursor Free has better multi-file context. Copilot Free has wider IDE support. For VS Code users, Cursor Free is usually the stronger choice.
What is the cheapest paid API for coding once free runs out?
GLM 4.7 Flash ($0.06 in / $0.40 out per 1M tokens), then GPT-5.4 nano ($0.20 in / $1.25 out per 1M tokens) and DeepSeek V4.1 Flash ($0.30 in / $1.20 out at peak, half off-peak). All three handle tool calls, so they work for agent loops, not just completions. DeepSeek pricing checked 2026-10-27 at api-docs.deepseek.com.
