Sentry Crons is great if you already use Sentry. If you don't, there's a simpler option.
The short version: If you're already paying for Sentry and using it for error tracking, Sentry Crons makes sense, it's integrated. If you just need cron monitoring, CronSignal is simpler and cheaper.
Sentry Crons is an add-on to Sentry's error tracking platform. Here's the breakdown:
Sentry's Team plan starts at $29/month. You can't use Sentry Crons without a Sentry subscription.
Every Sentry plan includes 1 cron monitor for free.
Each additional monitor costs $0.78/month, billed as pay-as-you-go usage.
Sentry Crons is a good fit if:
CronSignal is the better choice if:
Why pay $29/month for error tracking you won't use just to get cron monitoring?
CronSignal is one curl command. No SDK installation, no project configuration.
At 50+ checks, Sentry's costs add up. CronSignal is $5/month regardless.
Sentry's pay-as-you-go model means variable monthly bills. We're flat $5/month.
Sentry Crons integrates with Sentry's error tracking, so you see exceptions, but only if your code throws and you've instrumented it with the Sentry SDK. CronSignal captures raw stdout/stderr from any script, in any language, with a simple curl. Bash script that prints an error? You'll see it. Python script that exits non-zero? You'll see why.
If you use Sentry: Sentry Crons is convenient. You get integrated error tracking and cron monitoring in one place. The per-monitor pricing adds up with scale, but if you're already in the Sentry ecosystem, it makes sense.
If you don't use Sentry: There's no reason to pay for a full error tracking platform just to monitor cron jobs. CronSignal does one thing well, at a predictable price.
