Free AI Tools for Coding in 2026: What You Actually Get Without Paying

Quick answer
The best free AI coding tools in 2026 are Google Antigravity's free Individual plan, GitHub Copilot Free with 2,000 completions and 50 chat requests a month, and open-source agents such as Cline or OpenCode running a local model through Ollama. Note that Antigravity CLI replaced Gemini CLI for free users on 18 June 2026.

The free AI coding tools worth using in 2026 — Antigravity's free tier, GitHub Copilot Free, Gemini Code Assist, and open-source agents with local models — and the real limits of each.

Free AI Tools for Coding in 2026: What You Actually Get Without Paying

Short version: you can do serious work in 2026 without paying. Use Antigravity's free tier for agent work, Copilot Free for completions, and a local model for anything private or when limits run out. One thing many guides still get wrong: for free users, Google replaced Gemini CLI with Antigravity CLI on 18 June 2026.

Free AI coding tools and their limits, September 2026

Free hosted tiers

**Google Antigravity, Individual plan.** No subscription: unlimited tab completions and command requests, with basic weekly limits on the agent models. The most generous free agent tier this year. Details in our Claude Code vs Antigravity comparison.

GitHub Copilot Free. 2,000 code completions and 50 chat requests a month inside VS Code and other editors. GitHub moved Copilot to usage-based AI Credits in June 2026, so check current allowances. Verified students can get Copilot through the GitHub Student Developer Pack.

Gemini Code Assist. Gemini CLI's documentation lists 1,000 requests per user per day through a Google account and 250 with an unpaid API key. For unpaid-tier and Google One users, Gemini CLI itself was replaced by Antigravity CLI in June.

Free and unlimited: open source plus a local model

An open-source agent pointed at a local model has no meter at all:

The trade-off is quality on large multi-file tasks, and needing a machine with enough memory.

A free AI coding stack that covers most work

A free stack that covers most work

  1. Completions: Copilot Free in VS Code.
  2. Agent work: Antigravity's free tier.
  3. Private or over-limit work: Cline with a local model.
  4. Portable skills: keep SKILL.md files in the repo so they work in all three.

When paying starts to make sense

When weekly limits interrupt real work more than once a week, a $20 plan pays for itself in time. Compare the options in Claude Code vs Codex before choosing.

Frequently asked questions

What is the best completely free AI coding assistant?+

For zero cost with no ongoing limits, an open-source agent such as Cline or OpenCode connected to a local model through Ollama, because nothing is metered. The trade-off is quality on large tasks and needing a capable machine. For the best free hosted experience, Google Antigravity's free tier is the most generous in 2026, with unlimited completions and weekly-limited agent use.

Is GitHub Copilot free for students in India?+

Verified students can get Copilot through the GitHub Student Developer Pack, which has long included it at no cost, and anyone can use Copilot Free with 2,000 completions and 50 chat requests a month. GitHub moved Copilot to usage-based AI Credits in June 2026, so check the current student and free allowances on GitHub's pages before relying on them.

What happened to Gemini CLI's free tier?+

According to Gemini CLI's own documentation, Gemini CLI was replaced by Antigravity CLI on 18 June 2026 for unpaid-tier and Google One users. Gemini CLI is still open source, and its documentation lists separate quotas for Google-account and API-key routes, so older articles describing a generous free Gemini CLI tier may no longer apply to your account.

Are free AI coding tools safe to use with my company's code?+

Check your employer's policy first. Hosted free tiers send your code to the provider, and their data terms can differ from paid business plans. If you cannot send code outside, a local model through Ollama with an open-source agent keeps everything on your machine. For personal and open-source projects, the hosted free tiers are generally fine.

Can I build a real project using only free AI tools?+

Yes, many people do. A practical free stack is VS Code with Copilot Free for completions, Antigravity's free tier for agent work, and a local model for anything private or when you hit a weekly limit. The limits bite on long agent sessions, so plan larger refactors in smaller steps and keep a paid plan as an option for crunch weeks.
