Cronitor

Cronitor is a cron job and scheduled task monitoring platform that provides developers with instant alerts when jobs fail, run too long, or don't run at all. The platform offers a REST API for creating and managing monitors, recording job telemetry events, and configuring alert policies across teams. Cronitor supports job monitoring, heartbeat monitoring, website uptime checks, and Real User Monitoring (RUM), all accessible via a versioned HTTP API using Basic Auth with scoped API keys. SDKs are available for Python, Node.js, Ruby, PHP, Java, Go, and other languages through the cronitorio GitHub organization.

Cronitor publishes 4 APIs on the APIs.io network, including Cronitor Telemetry API API, Groups API, Notifications API, and 1 more. Tagged areas include Monitoring, Cron Jobs, Scheduled Tasks, Alerting, and Uptime.

The Cronitor catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/cronitor: open an issue to ask a question, or submit a pull request to add artifacts.
