Your app is up.Is it working?

A ping only checks that your server answers. Staygreen checks what it answers, that your crons did their job, and that Stripe’s webhooks arrived.

An example on sample data. Nothing real is touched.

Failures that pass a ping

Each one is a check you add in a minute, or that your coding agent adds for you. Coming soon means it isn’t running yet, and you don’t pay for it.

Your API says 200 while the database is gone

Assertions on the JSON body, like $.db.ok == true. A wrong value is an outage, even with a 200.

Alerts that say what broke

A failed request is checked again from a second location before anyone is woken. The alert carries the request, what it got and the response, so you can start fixing from your phone.

  • Email, Telegram, Slack, Discord or a signed webhook
  • A recovery notice when it’s fixed
  • On Telegram, acknowledge or pause from the message itself

Your users see it too

A status page on your own domain, in your colours. And a banner inside your app while something is wrong, so people don’t have to go looking.

You write the update, or your agent drafts it for you to publish. Free includes one page with HTTPS on your domain.

Your coding agent can read it

Staygreen has an MCP server and a REST API on every plan. Ask Claude Code or Codex what’s broken and it gets the evidence, not a guess. It can set up monitoring for a new app from its URL.

  staygreen: get_incidents(app: "askone", state: "open")

One open incident since 14:02: API health. /api/health returns 200, but $.db.ok is false from San Francisco and Toronto. The body says "too many connections". Your pool max is 10 in lib/db.ts.

Raise it to 25 and draft a status update for you to publish?
