Best Free AI Coding Tools in 2026
Not every AI coding tool needs a monthly subscription to be worth using. Some of the strongest options in 2026 are free permanently, not a 7-day trial with a countdown clock, and a couple of them are free specifically because they’re open source and you bring your own model.
Here’s what’s actually free right now, verified against each vendor’s own page, sorted by what kind of free they actually are.
| Tool | Free Tier Limit | Credit Card Required | Type |
|---|---|---|---|
| GitHub Copilot | 2,000 completions, 50 chat/agent requests/mo | No | Permanent free tier |
| Amazon Q Developer | 50 agentic requests/mo | No | Permanent free tier |
| Cursor (Hobby) | Limited agent requests | No | Permanent free tier |
| Google Antigravity | Unrestricted during public preview | No | Free during preview only, not guaranteed long-term |
| Cline | Unlimited (bring your own model) | No (free-tier models available) | Open source, free forever |
| Aider | Unlimited (bring your own model) | No (free/local models available) | Open source, free forever |
| Windsurf | Unconfirmed, pricing page redirects elsewhere | Unknown | Status unclear as of this writing |
Key Takeaways
- GitHub Copilot’s free tier (2,000 completions, 50 chat/agent requests monthly) and Amazon Q Developer’s free tier (50 agentic requests monthly) are both permanent, not trials, and need no credit card.
- Cline and Aider are free because they’re open source, you bring your own API key and pay only for model usage, or run a free-tier model like Gemini 2.0 Flash at no cost at all.
- Google Antigravity is free during its current public preview, worth trying now while that lasts, though “public preview” pricing isn’t guaranteed to stay free forever.
Permanently Free (No Subscription, No Trial Clock)
GitHub Copilot Free gives you 2,000 code completions and 50 chat or agent requests every month, renewing on a monthly cycle rather than counting down to zero. It plugs into VS Code, JetBrains, and Neovim, so there’s no new editor to learn (GitHub, Copilot plans).
Amazon Q Developer’s free tier includes 50 agentic requests a month plus 1,000 lines of code for Java transformation specifically, and gives you access to Claude models inside your IDE or CLI at no cost. It’s the strongest free option if you’re already building on AWS, since the paid Pro tier’s real advantage (IP indemnity, admin controls) mostly matters once you’re managing a team, not using it solo (AWS, Q Developer pricing).
Cursor’s Hobby tier is free with no credit card required. Usage is limited compared to the $20/month Pro plans, but it’s enough to genuinely test whether Cursor’s agent-first workflow fits how you work before paying anything (Cursor, pricing).
Google Antigravity is Google’s newer agentic development platform, currently free for individuals during its public preview, according to Google’s own developer blog. It runs as either a standalone app or an IDE, with agents that can plan and execute tasks across your editor, terminal, and browser in one flow. The honest caveat: “public preview” pricing is explicitly temporary language, not a permanent commitment, so don’t build a workflow entirely around it assuming it stays free indefinitely (Google Developers Blog, Build with Google Antigravity).
Free Because They’re Open Source (Bring Your Own API Key)
This category works differently: the tool itself costs nothing, but you’re paying your model provider directly for whatever you use. That can be cheaper than a subscription for light use, or comparable to it for heavy daily use. Either way, there’s no vendor subtracting a margin on top of the model cost.
Cline (originally released as “Claude Dev,” the VS Code extension ID is still saoudrizwan.claude-dev) is a free, open-source VS Code extension with agent-mode capabilities: it can read files, write files, run terminal commands, and even interact with your running app in a browser to verify its own work. It supports more than 30 model providers. If you want to run it at genuinely zero cost, Gemini 2.0 Flash’s free tier (15 requests/minute, 1M token context) or DeepSeek V3 through OpenRouter’s free tier both work as backing models.
Aider is a free, open-source, terminal-first coding tool that works with Claude, DeepSeek, OpenAI, or local models through Ollama. Like Cline, there’s no Aider-specific subscription, you supply an API key and pay your provider directly (aider --api-key anthropic=), or run a fully local model for zero marginal cost per request.
One Worth Flagging as Uncertain
Windsurf (formerly Codeium) used to be a strong entry in this category with its own generous free tier. As of this writing, its dedicated pricing page consistently redirects to Devin’s pricing page instead. Both products are now under Cognition, and we can’t confirm Windsurf’s current standalone free-tier terms from its own site as a result. If you’re specifically interested in Windsurf, check its current pricing directly rather than trusting older reviews (including, potentially, this one by the time you read it).
Which Free Tier Actually Fits You
- You want zero setup and you’re already in VS Code or JetBrains: GitHub Copilot Free.
- You’re building on AWS already: Amazon Q Developer’s free tier, the Claude model access alone is a solid deal at $0.
- You want agent-mode autonomy without paying anything, and don’t mind an extension over a full IDE: Cline, paired with a free-tier model like Gemini 2.0 Flash.
- You live in a terminal and want to bring your own model: Aider.
- You want to try the newest agent-first workflow while it’s free: Google Antigravity, with the explicit caveat that “free” here means “free during public preview,” not “free forever.”
None of these free tiers include the highest-capability agent workflows the paid tools offer, if you outgrow one, GitHub Copilot vs Cursor vs Claude Code comparison and our Best AI Coding Tools & IDEs buying guide both cover what the step up actually costs and whether it’s worth it.

The Bottom Line
Free AI coding tools in 2026 aren’t a compromise the way they were a couple of years ago. GitHub Copilot’s and Amazon Q Developer’s free tiers are genuinely usable daily, not just a taste before an upsell, and Cline plus a free-tier model gets you real agent capability at zero cost if you’re willing to run an extension instead of a dedicated IDE.
Start with whichever one matches your existing setup rather than the one with the most features. You can always upgrade once you’ve hit a real limit, not before.
