Dev3000 is a CLI tool that captures your entire development session: server logs, browser console output, network requests, screenshots, and user interactions in one unified timeline. From Vercel Labs. Free, MIT-licensed.
Install via npm or bun globally, run d3k in your project, and it hooks into your Node.js server and browser. AI agents (Claude Code, Cursor, Windsurf) can read the live timeline for context. No persistent server required. The cloud collaboration features use Vercel Sandbox if you need to share sessions.
If you use AI coding assistants and spend time context-switching between terminal logs and browser DevTools, this is directly useful. The CLI is free with no limits. Solo developers working with agentic tools are the target audience here.
The catch: Vercel Labs means experimental. Headless capture mode has rough edges. Deeper cloud features will likely require deeper Vercel platform integration over time.
Free vs Self-Hosted vs Paid
open coreFree tier: CLI is fully free and open source (MIT).
Self-hosted: Local-only mode runs entirely free.
Cloud features: Sharing and AI integration via Vercel Sandbox requires a Vercel account. Sandbox pricing is usage-based.
CLI free forever; cloud features tie to Vercel Sandbox billing.
