Aide

Aide is an open-source AI code editor built as a fork of VS Code, developed by CodeStory. It layers agentic AI features on top of the familiar VS Code shell: a combined chat-and-edit interface, an inline editing widget triggered with Ctrl/Cmd+K, and agents that can iterate on their own changes by reacting to linter errors and test failures. It also does AST-aware navigation, letting you jump around a codebase by code structure rather than just text search, and AI-driven completions tuned for reasoning across multiple files at once.

It's aimed at engineers working on problems that don't fit neatly into single-file edits, refactors, bug fixes, or feature work that touches several files and requires the editor to keep track of how those changes relate. Because it started from VS Code, existing keybindings, extensions, and settings mostly carry over, so switching doesn't mean relearning an editor.

Being open source and self-hostable is the main differentiator from closed AI editors: teams that need to inspect how the agent behaves, run it against their own model backend, or keep code from touching third-party servers can do that. It's a smaller, community-driven project rather than a heavily funded commercial one, so its ecosystem and polish are more limited than bigger AI-editor competitors.
