Error tracking

When a script breaks,
you see why.

It fires the moment a real device hits the bug. You get the clicks that led there, a stack trace mapped to your own source, the release it started in, and an agent that can read all of it and fix it.

Performance

Performance your visitors actually feel.

A Lighthouse score from your laptop is one fast run on one machine. JAMP measures Core Web Vitals from your real users at p75, then runs on-demand lab audits to tell you which pages are slow, why, and whether your last deploy helped.

Tiny by design

Heavy analytics is what tanks your performance scores. JAMP's doesn't: the whole analytics tracker is 473 bytes gzipped, and each pillar is a separate drop-in you load only when you want it.

MCP server

Plug your AI agent
into production.

JAMP speaks MCP, so Claude, Cursor and other agents can read your errors, uptime and traffic. Ask what is breaking and the agent pulls the stack trace and the deploy it started in, then goes and fixes it. Connect in one click with OAuth, or with a token.
