Best Free AI Code Assistants 2026: 8 Options Compared

A free AI code assistant is free in one of three ways, and the way matters more than the feature list. Some products give you a capped free tier of a hosted service: GitHub Copilot lists 2,000 completions a month and Amazon Q Developer lists 50 agentic requests a month, so a busy week can use them up. Others are open-source tools, such as Continue, Cline, aider, goose and OpenCode, where the software costs nothing but you connect your own model, either a paid API key or a local model you run yourself. A third group, such as Cursor, offers a free tier with a small allowance and expects you to upgrade. Pick the capped hosted tier if you want something working in the editor within minutes and write code at a modest pace. Pick an open-source agent if you already pay for a model provider or want to run models locally, because then the tool adds no second bill and no usage cap of its own. The trade-off is setup and cost control: with your own key, a long agent session can spend real money without any warning from the tool itself. Check which editor you use before anything else, since several of these work only in VS Code or the terminal. The eight tools below each state the limit that applies.
