AI coding assistants have become essential for developers. They autocomplete code, suggest fixes, and even write entire functions. The good news? Many powerful options are completely free. Here’s our curated list.
GitHub Copilot is the most popular. While the full version costs, it’s free for verified students and open-source maintainers. It integrates deeply with VS Code, JetBrains, and Neovim.
Codeium offers unlimited code completions for individuals. It supports 40+ languages and works in VS Code, JetBrains, and even Jupyter. No credit card required.
Tabnine provides solid, privacy-focused AI completions. The free tier allows whole-line and full-function completions running locally, which is great for code privacy.
AWS’s CodeWhisperer is free for individual developers. It supports multiple languages and includes security scanning. If you use AWS often, it’s a must-have.
Replit’s online IDE has a built-in AI called Ghostwriter. The free tier includes 1000 AI cycles per month, perfect for small projects.
Not a direct IDE plugin, but you can paste code, ask for explanations, generate boilerplate, and debug. The free GPT-4o mini is surprisingly capable.
Anthropic’s Claude offers a free chat interface that excels at code generation and review. Often produces cleaner code than ChatGPT for complex logic.
Gemini’s free tier in Google AI Studio lets you test code generation, especially useful for Android/Kotlin developers.
Start with one and combine with a chatbot. All these are listed in our AI Directory.
