Up is not the same as healthy.

Genki checks whether a service answered—and whether the answer was right. One Worker, one D1 database, quiet alerts, and a CLI that agents can operate safely.

Small on purpose

Deploy once. Add a monitor in one command.

  1. 01

    Own the deployment

    Generate a complete Worker project, provision D1, test it, migrate it, and deploy it with Wrangler.

    genki init monitoring
cd monitoring && bun install
genki setup
bunx wrangler secret put API_TOKEN
genki deploy
  2. 02

    Connect safely

    Store the deployment as a named context. Tokens are read from standard input and redacted everywhere.

    printf '%s' "$GENKI_TOKEN" | genki context add personal \
  --url https://genki-monitor.<account>.workers.dev \
  --token-stdin
  3. 03

    Monitor the URL

    Genki creates the service and production environment, then runs the exact check immediately.

    genki add https://example.com/health
genki status

A useful distinction

A 200 can still be a failure.

Templates add reviewed semantic checks without turning the monitoring engine into a catalog of product-specific special cases.

genki add https://grafana.example.com/api/health \
  --template grafana-health \
  --service grafana
Down
The service could not be reached.
Unhealthy
It answered, but failed a health assertion.
Healthy
It answered and passed every assertion.

Sustainable open source

Useful software, without another monthly bill.
