deja-vu for VS Code, Cursor, Windsurf & Antigravity

Your coding agents stop re-debugging what you already fixed.

deja-vu indexes the session transcripts Claude Code, Cursor, Codex, Windsurf, Copilot Chat, OpenCode, Cline, Roo Code and 35 other coding agents already write to disk — locally, in one Go binary, with no LLM and no background daemon.

deja-vu demo

What this extension does

Shows live deja statusline state in the IDE status bar (sessions indexed across your agents, memory recalls served today, and workspace history). If deja is not installed yet, clicking the status bar item runs npx -y @vshulcz/deja-vu install --auto in a terminal to wire all detected agents on your machine.

Quick install

brew install deja-vu && deja install --auto
# or without Homebrew:
npx -y @vshulcz/deja-vu install --auto

Install the status bar extension from the CLI:

code --install-extension vshulcz.deja-status
