Best Free AI Coding Tools in 2026

The best AI coding tools at zero cost: editor integrations, chat-based assistants and free API tiers, plus the near-free API to use when limits bite.

RecentPricing last verified: Sep 12, 2026Source: Model registry + editorial review
Cursor Free at $0 is the best free AI coding tool: 2,000 completions a month, a chat allowance and full codebase indexing in an editor built for AI-native development. Runner-up is GitHub Copilot Free at $0, with the same 2,000 completions and the widest IDE support. ChatGPT Free covers chat-based debugging, the Gemini API free tier gives builders Gemini 3.8 Flash without a card, and when free finally runs out DeepSeek V4 Flash at $0.05 in / $0.16 out per 1M tokens costs cents rather than dollars.

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 Flash at $0.05 in / $0.16 out per 1M tokens when a free limit blocks you.

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 move to Cursor Pro at $20.

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?

DeepSeek V4 Flash at $0.05 in / $0.16 out per 1M tokens, then GLM 4.7 Flash ($0.06 in / $0.40 out per 1M tokens) and GPT-5.4 nano ($0.20 in / $1.25 out per 1M tokens). All three handle tool calls, so they work for agent loops, not just completions.
