Best Free AI Coding Tools: 10 Free Tiers Compared
· Updated October 24, 2026
The best free AI coding tools in October 2026 are GitHub Copilot Free for autocomplete and chat in almost any editor, Google Antigravity for a free agent-first IDE and command-line tool, and Devin Desktop, the editor formerly called Windsurf, for unlimited free Tab completions.
For open-source freedom, Cline and OpenCode run any model you like, including free local models that keep your code off the cloud.
The free-tier map changed a lot this year. Google retired Gemini Code Assist for individuals and the free Gemini CLI login in June 2026, Windsurf became Devin Desktop, Cursor moved its plans into xAI's X Subscription, and Tabnine dropped out after its sale to Tricentis.
Every limit below was checked against official pricing pages and docs in October 2026, and we say where a vendor does not publish a number.
What Are Free AI Coding Tools?
Free AI coding tools are editors, extensions, command-line agents and chat assistants that use AI to suggest, write, explain and fix code at no cost, usually with a monthly or weekly cap. They save time on boilerplate and debugging, but a human still needs to review their output.
There are three main types. Autocomplete and AI editors suggest code as you type. Coding agents take a task, edit several files and run commands, usually with your approval. Chat assistants explain errors and draft code you paste in.
Our guide to the best AI agents explains agents more broadly, and our list of the best AI coding assistants compares paid plans for when you outgrow a free tier.
Quick Comparison: 10 Best Free AI Coding Tools
GitHub Copilot Free is our top pick overall, followed by Google Antigravity and Devin Desktop (formerly Windsurf). Here is how all 10 compare on best use, free tier and tool type. Free limits were checked in October 2026 and change often, so confirm them before you rely on one.

What Makes a Good Free AI Coding Tool?
A good free AI coding tool allows enough usage to finish real work, uses a capable model, fits your editor and states its limits clearly. A free plan that runs out after a few requests is a trial, not a tool.
We weighed five things: how much work the free tier allows, model quality, editor and terminal support, privacy controls and clarity of limits. Tools with unlimited autocomplete or a free open-source option ranked higher, because they keep working when a quota runs dry.
Best Free AI Code Editors and Autocomplete
1. GitHub Copilot Free: Best overall free AI coding assistant
GitHub Copilot Free is the no-cost tier of the most widely supported AI coding assistant.
What it does well. Copilot works in VS Code, Visual Studio, JetBrains IDEs, Xcode, Vim, Neovim, Zed and Eclipse, plus the Copilot CLI and github.com. Free includes 2,000 code completions a month, and chat and agent mode draw from a monthly allowance of GitHub AI Credits. Verified students get the free Copilot Student plan with unlimited completions.
Key features:
- 2,000 code completions per month
- Chat and agent mode from a monthly credit allowance
- Works in eight editor families and the terminal
- Free Copilot Pro for some verified teachers and open-source maintainers
Pricing. Free. Copilot Pro is about $10 a month with 1,500 AI credits, and Pro+ is about $39 a month.
Best for: Developers who want free AI help in the editor they already use, and students.
Limitations. GitHub does not publish how many chat requests the free credit allowance covers, and Free uses automatic model selection only. Since April 24, 2026, GitHub may use interaction data from individual plans for AI training unless you opt out in your Copilot settings.
2. Google Antigravity: Best free agent-first IDE and CLI
Google Antigravity is Google's agentic coding platform, which replaced Gemini Code Assist for individuals and the free Gemini CLI login on June 18, 2026.
What it does well. Antigravity comes as a full IDE, a terminal CLI and a desktop app for running agents in parallel, on macOS, Windows and Linux. The free plan includes unlimited Tab completions and unlimited command requests, with agent work under weekly rate limits.
In October 2026, free models include Gemini 3.8 Flash, Claude Sonnet 4.6, Claude Opus 4.6 and GPT-OSS-120b.
Key features:
- Unlimited Tab completions
- Agent mode with weekly rate limits
- IDE, CLI and a desktop app for parallel agents
- Runs on macOS, Windows and Linux
Pricing. Free for individuals. Google AI Pro and Ultra subscriptions add higher limits.
Best for: Developers who want a free agentic IDE and terminal agent from one Google account.
Limitations. Google does not publish the weekly quota as a number. Its models page says the Claude and GPT-OSS models leave the free tier on November 2, 2026, leaving Gemini models.
3. Devin Desktop (formerly Windsurf): Best for unlimited free autocomplete
Devin Desktop is the new name for Windsurf, the AI code editor from the team that built Codeium.
What it does well. Cognition renamed Windsurf to Devin Desktop in June 2026, and windsurf.com now redirects to devin.ai. The free plan keeps unlimited Tab completions and unlimited inline edits, plus a light agent quota that refreshes daily and weekly.
Key features:
- Unlimited Tab completions
- Unlimited inline edits
- Light agent quota that refreshes daily and weekly
- Built on the Windsurf editor
Pricing. Free. Pro is about $20 a month with higher quotas and frontier models, and Max is about $200 a month.
Best for: Developers who want unlimited AI autocomplete without paying.
Limitations. The agent quota is described only as "light," and free users get limited model choice. Guides that list Codeium and Windsurf as separate free tools are out of date.
4. Cursor Free: Best for trying Cursor at no cost
Cursor is a popular AI code editor that still has a free plan, but the plan changed in October 2026.
What it does well. Cursor's pricing page now bundles its plans with Grok and X features, sold through X Subscription Corp. The Free plan gives you the full editor with limited agent and chat requests, drawn from a weekly pool that covers Cursor's Composer 2.5 model and Grok models.
Key features:
- Full Cursor editor at no cost
- Limited agent and chat requests
- Composer 2.5 and Grok models
- Usage pool that refreshes weekly
Pricing. Free. Plus is about $8 a month with Grok models only, and Premium is about $30 a month with access to third-party models at API list price.
Best for: Developers who want to try Cursor before paying.
Limitations. Cursor does not publish exact free limits, and the weekly pool is shared with Grok's apps. Claude and GPT models are not in the free pool, and reviews describing the old Hobby plan no longer match.
Best Free Open-Source AI Coding Agents and CLIs
5. Cline: Best free open-source agent for VS Code
Cline is a free, open-source coding agent that runs in your editor with the model of your choice.
What it does well. Cline edits several files, runs terminal commands and asks your approval before each edit and command by default. It is free for individuals under the Apache 2.0 license. Bring your own API key from OpenAI, Anthropic, Google and others, or run a local model through Ollama or LM Studio so your code stays on your machine.
Key features:
- VS Code extension, JetBrains plugin and CLI
- Bring your own key, or pay for inference at cost
- Local models through Ollama and LM Studio
- Approval for each edit and command
Pricing. Free. You pay only your model provider's API rates, or nothing with a local model.
Best for: Developers who want full control over models, costs and privacy.
Limitations. Cline is only as good as its model, and strong cloud models cost money on long tasks. Its docs suggest 16 to 32 GB of RAM for small local models and 64 GB or more for larger ones.
6. OpenCode: Best free terminal coding agent
OpenCode is an open-source AI coding agent for the terminal that works with almost any model.
What it does well. OpenCode is MIT licensed and connects to more than 75 model providers, including local models. It ships with free models you can use without an account, and you can sign in with an existing GitHub Copilot or ChatGPT Plus or Pro subscription.
Key features:
- MIT-licensed open-source project
- More than 75 providers, including local models
- Free models with no account needed
- Terminal, desktop app and IDE extension
Pricing. Free. Optional paid models are available through OpenCode Zen, and other providers bill at their own rates.
Best for: Terminal users who want a free agent not tied to one AI company.
Limitations. Free models are offered for a limited time and change often. Some may use your data to improve the model during their free period, so read each model's note before using private code.
7. Kiro Free: Best free spec-driven agent from AWS
Kiro is AWS's agentic IDE and CLI, and AWS's recommended path for developers leaving Amazon Q Developer.
What it does well. Kiro is built around spec-driven development, turning a prompt into requirements, a design and tasks before writing code. The free plan includes 50 credits a month with Claude Sonnet 4.5 and open-weight models such as Qwen3 Coder Next and DeepSeek 3.2, subject to rate limits.
Key features:
- 50 credits per month
- Claude Sonnet 4.5 and open-weight models
- Kiro IDE, Kiro CLI and Kiro Web
- Spec-driven workflow
Pricing. Free. Pro is about $20 a month with 1,000 credits, and Pro+ is about $40 with 2,000 credits.
Best for: AWS users and developers who like to plan before they code.
Limitations. Fifty credits go quickly, and unused credits do not roll over. AWS ends support for Amazon Q Developer IDE plugins on April 30, 2027, so Q Developer's free tier is not a long-term choice.
Best Free AI Chat and App Builders for Coding
8. ChatGPT Free with Codex: Best free coding chat with an agent
ChatGPT's free plan covers coding chat and now includes Codex, OpenAI's coding agent.
What it does well. OpenAI's Codex pricing page says Codex is included in ChatGPT Free, Go, Plus, Pro and business plans, with Free aimed at quick coding tasks. You can talk through a bug in chat, then hand a small task to Codex without paying.
Key features:
- Coding chat for explanations and debugging
- Codex agent for quick tasks
- Web, desktop and mobile apps
- Low-cost upgrade through Go
Pricing. Free. Go is about $8 a month, Plus about $20 and Pro from about $100.
Best for: Developers who want chat help plus a first taste of a coding agent.
Limitations. OpenAI does not publish Codex limits for Free, and some access is subject to rollout. Free suits quick tasks, not long agent sessions.
9. Claude Free: Best free chat for explaining and debugging code
Claude's free plan is a capable coding chat, but it does not include Claude Code.
What it does well. Claude Free includes code execution, file creation, web search and Artifacts, which preview small apps you build in chat. It is a good place to paste a stack trace or plan a refactor. Our ChatGPT vs Claude comparison covers how the two differ.
Key features:
- Code execution and file creation
- Artifacts for small apps and previews
- Web search for current docs
- Web, desktop and mobile apps
Pricing. Free. Claude Code comes with paid plans, starting with Pro at about $20 a month, or about $17 a month billed annually.
Best for: Developers who want a second opinion on tricky code.
Limitations. Claude Code, Anthropic's terminal agent, is not on the free plan. Free usage limits are not published as a fixed number, so long sessions can be cut short.
10. Replit Starter: Best for beginners building in the browser
Replit Starter is the free plan of Replit's browser-based IDE and AI app builder.
What it does well. Describe an app and Replit's Agent builds it, with nothing to install. Starter includes daily Agent credits up to a monthly cap, monthly cloud credits, the Lite build mode for quick edits and one free published app.
Key features:
- Agent credits that reset daily
- Lite build mode for quick changes
- One free published app
- Runs in the browser
Pricing. Free. Core is about $20 a month, or about $18 billed annually, and Pro is about $100 a month.
Best for: Beginners and anyone prototyping without installing tools.
Limitations. Your free published app goes down after 30 days and shows a "Made with Replit" badge. Full build and Plan Mode need a paid plan, and the daily credit amount is not published.
How Should You Choose a Free AI Coding Tool?
Pick one tool for your editor and one for chat, then match them to how you work. Add an agent only when you have a clear task for it.
- Student: Copilot Student for unlimited completions, plus Google Antigravity for agent work.
- VS Code user: Copilot Free for completions and Cline for multi-file tasks.
- JetBrains user: Copilot Free or Cline's JetBrains plugin. JetBrains' own AI Free tier gives only 3 AI credits every 30 days.
- Terminal user: OpenCode, the Antigravity CLI or the Kiro CLI.
- Privacy-first: Cline or OpenCode with a local model through Ollama.
- Unlimited autocomplete: Google Antigravity or Devin Desktop.
- Beginner: Replit Starter, or ChatGPT Free to learn by asking questions.
Always review AI-written code before it ships. Our guide to the best AI code review tools covers tools that check pull requests for bugs and security issues.
How We Evaluated These Free AI Coding Tools
We built this list from official pricing pages, product docs and changelogs, checked in October 2026, using news coverage only to confirm dates such as renames.
Tools are ordered by how much real coding the free tier allows, model access, editor support, privacy controls and clarity of limits.
This list is not based on hands-on benchmarks, and many vendors describe free quotas only as "limited" or "light," so try each free tier on your own projects.
Is GitHub Copilot free?
Yes. GitHub Copilot Free costs nothing and includes 2,000 code completions a month, plus chat and agent mode from a monthly allowance of AI credits. Verified students get Copilot Student with unlimited completions, and verified teachers and popular open-source maintainers may get Copilot Pro free. Otherwise, Pro costs about $10 a month.
Are free AI coding tools safe for private code?
It depends on where your code goes. Cloud tools such as Copilot, Antigravity, Cursor and ChatGPT send code context to the vendor's servers, and policies differ. GitHub may train on interaction data from individual Copilot plans unless you opt out, and some OpenCode free models may use your data during their free period.
The safest free setup is Cline or OpenCode with a local model, which keeps code on your computer. Never paste passwords or API keys into any AI tool, and check your employer's policy first. Our guide on whether AI chatbots are safe covers the wider privacy picture.
Can you code with AI for free without limits?
Only with a local model. Every hosted free tier has a cap, whether it is Copilot's 2,000 monthly completions, Kiro's 50 credits or Antigravity's weekly agent limits. Antigravity and Devin Desktop offer unlimited Tab completions, but their agents are capped.
A local model through Ollama with Cline or OpenCode has no usage cap, but it needs a capable computer and is usually weaker than top cloud models.
The Bottom Line
GitHub Copilot Free is the best starting point for most developers, because it works in almost every editor and students get unlimited completions. Add Google Antigravity or Devin Desktop for unlimited Tab completions, Cline or OpenCode for open-source control, Kiro if you work on AWS, and ChatGPT or Claude for free coding chat.
Next steps: Install one free editor tool and one free chat assistant, use them on a real project for two weeks and upgrade only the one whose limits slow you down. For more no-cost picks, see our list of the best free AI tools.
