Adam Balée

I'm a web developer with 15+ years working with agencies and client sites.

I built Sentinel because I was juggling separate tools for uptime, SSL, and DNS monitoring and wanted everything in one place. It grew a spine along the way: every check runs from four regions at once, and alerts only fire when the regions agree a site is down.

Lately I'm building for AI agents too. Sentinel ships an MCP server, and I maintain a directory of agent-payable APIs where every listing is verified by a live monitor.

Built with Laravel, Inertia, and Horizon. Solo, no funding.

Tools I’ve built for agencies and client work

Sentinel
Uptime monitoring for whoever's responsible for keeping things up. Every check runs from four regions at once, and alerts only fire when the regions agree, so a network blip never pages you and a real outage can't hide. Status pages, SSL, DNS, and cron monitoring included, plus an MCP server so AI agents can use it too.

I catalogued everything an AI agent can buy. The list is shorter than the hype.
