You can get a capable AI coding assistant for free in 2026. GitHub Copilot now has a free tier, Cursor and Windsurf offer free plans, and the open-source tools Continue, Cline, and Aider are entirely free and connect to any model you choose, including free LLM APIs and local models. This guide compares eight free AI coding assistants, the real limits on each free tier, and the one setup that gives genuinely unlimited AI coding at $0. If you searched for a free Copilot or Cursor alternative, the short answer is at the top of the table.

GitHub Copilot (free tier)
- Type: Cloud assistant in VS Code, JetBrains, and others
- Free tier: A monthly allowance of completions and chat messages at $0, introduced to compete with the free open-source tools
- Agentic edits: Limited on free; the agent mode is stronger on paid
- Best for: The path of least resistance. If you already use VS Code, the Copilot free tier is the fastest way to try AI coding with no setup.
Continue.dev
- Type: Open-source extension for VS Code and JetBrains
- Free tier: Fully free and open source; you connect it to any model
- Agentic edits: Yes, with inline edits, chat, and autocomplete
- Best for: The best free Copilot replacement. Point Continue at a free LLM API or a local model and you get completion and chat with no subscription and no per-message cap beyond the model's own.
Continue is the recommendation for most people who want a free Copilot alternative. It is open source, editor-native, and model-agnostic, so it never locks you into one vendor's pricing.
Cline
- Type: Open-source VS Code extension (autonomous agent)
- Free tier: Fully free; you supply the model and API key
- Agentic edits: Yes, it plans, edits multiple files, and runs commands with your approval
- Best for: Free agentic coding. Cline is the strongest free option when you want an assistant that does multi-step work, not just autocomplete.
Aider
- Type: Open-source command-line tool
- Free tier: Fully free; bring your own model
- Agentic edits: Yes, with first-class git integration (each change is a commit)
- Best for: Terminal-driven developers. Aider's git workflow makes AI edits reviewable and reversible, and it runs on any model including cheap or free APIs.
Windsurf
- Type: Cloud AI editor (formerly Codeium's editor; acquired by Cognition and rebranded Devin Desktop in June 2026)
- Free tier: Free plan with a daily quota for agentic actions plus unlimited Tab autocomplete
- Agentic edits: Yes; the built-in agent (Cascade, being replaced by Devin Local from July 2026) edits across files
- Best for: A free agentic IDE that works out of the box, if you are happy in a dedicated editor rather than a VS Code extension.
Cursor
- Type: Cloud AI editor (VS Code fork)
- Free tier: Free plan with a limited number of fast model requests per month
- Agentic edits: Yes, strong agent mode
- Best for: Trying the leading AI IDE for free. The free tier is enough to evaluate it; heavy use needs the paid plan.
Amp (Sourcegraph)
- Type: Cloud agent in VS Code, Cursor, and a CLI
- Free tier: A free-forever plan for individuals, then pay-as-you-go with no markup on model usage
- Agentic edits: Yes, autonomous multi-file editing with a "smart" mode powered by frontier models
- Best for: Individual developers who want an agentic coder from the Sourcegraph team. Amp is the free successor to Cody, which became enterprise-only ($59/user/month) in mid-2025.
Zed AI
- Type: A fast native editor with built-in AI
- Free tier: Free tier of AI features inside the Zed editor
- Agentic edits: Yes
- Best for: Developers who want a fast, modern editor with AI built in rather than bolted on.
The unlimited free setup
The cloud free tiers (Copilot, Cursor, Windsurf) all cap monthly usage. To get genuinely unlimited AI coding at $0, use an open-source assistant with a model you do not pay for. Two routes work:
- Free API route. Install Continue or Cline, then point it at a free LLM API such as Gemini, Groq, or an OpenRouter free model. You get completion and agentic edits limited only by the API's rate limit. The provider list is in the guide on free LLM APIs.
- Local route. Run a model on your own machine with Ollama and connect Continue or Cline to it. Nothing leaves your computer, there is no usage cap, and it is fully private. See best local LLM for which model fits your hardware.
Either route turns a free open-source editor extension into an assistant with no monthly ceiling, which is something no cloud free tier offers.
Frequently asked questions
Is there a free AI coding assistant in 2026? Yes, several. GitHub Copilot now has a free tier with monthly completion and chat limits. Open-source tools Continue, Cline, and Aider are fully free and connect to any model, including free LLM APIs. Windsurf and Cursor also offer free tiers, so you can get AI code completion at $0.
What is the best free GitHub Copilot alternative? For most developers, Continue.dev is the best free Copilot alternative: open source, works in VS Code and JetBrains, and connects to free or local models. If you want an autonomous agent that edits files, Cline (open source) is the strongest free option. Codeium-style completion is also free in Windsurf.
Can I use an AI coding assistant for free with no usage limit? Yes, by self-routing. Open-source assistants like Continue, Cline, and Aider have no built-in cap; you supply the model. Point them at a free LLM API (Gemini, Groq, OpenRouter) or a local model via Ollama and you get unlimited AI coding for $0, limited only by the underlying model's rate limits.
Are free AI coding tools private? It depends on the model, not the editor. Cloud assistants (Copilot, Cursor, Windsurf free tiers) send code to a provider. Open-source tools paired with a local model via Ollama keep everything on your machine, which is the only fully private free setup. Check each provider's data-retention policy for cloud use.
Do I need a paid plan for agentic coding? Not necessarily. Cline and Aider are free, open-source agents that edit files and run commands, and they work with any model you point them at, including free APIs. The paid plans (Cursor, Copilot, Windsurf) buy convenience and stronger hosted models, but the agent capability itself is available for free.
