Looking for a free or open-source alternative to Cronitor? Pingcron is the closest direct swap — MIT-licensed source on GitHub, or a $29 one-time packaged install. Since you're already auditing what you pay Cronitor every month, here are four more pay-once tools from the same catalog worth a look while you're at it — different jobs, same idea: buy the software once instead of renting it forever.
1. Pingcron — replaces Cronitor
Your jobs ping a URL when they run — Pingcron alerts you when a ping is late or missing. $29 once vs Cronitor's $10/mo. Free on GitHub, or the packaged installer on Whop.

2. Hookscope — Self-hosted webhook capture, inspection, replay & forwarding — URLs that never expire.
Replaces Pipedream ($29/mo). $24 once. See Hookscope →
3. Snapfleet — One endpoint turns any URL into PNG, JPG or PDF — on your own server, $0 per render.
Replaces Urlbox ($19/mo). $39 once. See Snapfleet →
4. Wrangle — 10 dev data tools — JSON convert, JWT decode, diff, regex, hash — 100% offline, one app.
Replaces DevUtils ($29 (macOS only)). $15 once. See Wrangle →
5. Vaultkeeper — Postgres, MySQL, SQLite & Mongo dumps on cron — encrypted, shipped to S3/FTP/disk, with failure alerts.
Replaces SimpleBackups ($29/mo). $39 once. See Vaultkeeper →
Why this list is worth bookmarking
Every app above is a one-time purchase with MIT-licensed source, no accounts with us and no telemetry. None of them are trying to be the next Cronitor — they're trying to be the last subscription you pay for that specific job.

Your jobs ping a URL when they run — Pingcron alerts you when a ping is late or missing.
