Captures your web app's complete development timeline - server logs, browser events, console messages, network requests, and automatic screenshots - in a unified, timestamped feed for AI debugging.
vercel-labs/dev3000 is a local web debugging runtime that records a web app's server logs, browser events, errors, network activity, interactions, and screenshots in one timestamped timeline. Coding agents use it to run and inspect web applications while reproducing bugs. Its catalogue add-ons teach agents how to operate the runtime and examine its debugging evidence.
This repository also configures its own agents. See what dev3000 tells them →

Use when the user asks to use d3k, run/dev/test/debug a web project with d3k, or reproduce a browser issue. Own the runtime: reuse or background-start d3k non-interactively, wait for readiness, use its project-stable managed Chrome profile, and inspect unified browser/server evidence.
