What the publisher says

From the Devloop repository's README, as published. We do not edit it. Read it on GitHub

Browser control + dev-server logs on one correlated timeline — for AI agents and humans.

A unified dev-loop tool: it drives a browser and your dev server, pushing both sides into one timestamped buffer so you can correlate a browser console error with the backend stack trace from the same moment. It runs two ways from a shared core:

  • Headless (stdio) — drives Chrome via Puppeteer, served over stdio. The lightweight mode Claude Code spawns per session. Run devloop-mcp daemon to instead serve one shared, long-running instance over HTTP/SSE that many agents/sessions connect to (see Daemon mode).
  • Cockpit (Electron) — a single desktop window: tabbed browser panes (embedded WebContentsViews driven via CDP) with a browser bar (back/forward/reload + address) beside a collapsible side panel that toggles between logs and a repro builder. Project picker, auto-navigate, pop-out targets. The renderer is React 19 + Tailwind v4 + Radix + lucide-react. Serves the same tools over HTTP.

Because every event (browser console/network/page-errors and server stdout/stderr) shares one monotonic clock, getlogsaround / repro return a correlated, cross-source slice of the timeline.

Native targets — Expo / React Native (iOS + Android)

The cockpit also drives Expo/React Native projects, not just web. Open a native project and you get one pane with a Web · iOS · Android target switcher, a bundler toggle (Metro) separate from a Build button (expo run:ios / expo run:android, with @expo/fingerprint staleness detection), and:

Install directly

Runs npx -y devloop-mcp on your machine. Read the scan report first; the gateway never runs local packages.
