Popular Open Source AI Coding Assistants

AI coding assistants have moved fast from autocomplete plugins to agents that can read a codebase, run commands, and open pull requests on their own. Open source options let you inspect exactly what’s being sent to which model, swap in a different LLM provider or a self-hosted model, and avoid being locked into one vendor’s pricing or data policy.
Aider and Cline work directly against your local codebase from the terminal or editor, Continue is an open source IDE extension you can point at any model provider, OpenHands targets more autonomous, multi-step coding tasks, and Tabby is a self-hostable code completion server for teams that want to keep everything on their own infrastructure.
