PaaS cron alternatives
How Crontap compares to the cron primitives shipped by Heroku, Render and the rest of the PaaS pack.
About this topic
PaaS
Most PaaS platforms ship a scheduler that matches the platform's own conventions. Heroku Scheduler runs on three fixed cadences (10 min, 1 hour, 24 hours) and spins a one-off dyno per run. Render Cron Jobs run as separate paid services, billed per cron. Fly Machines support cron schedules but require some shell wiring. The comparison pages below put each one head-to-head against Crontap. Where the native scheduler is the right pick (one daily Rake task, you live entirely on Heroku, you're happy with UTC), we say so up front.
Crontap fires any cron expression at the HTTP endpoint of your choice (a route on your existing dyno or service, an external API, anywhere reachable) without spinning a fresh container per run. The schedule lives outside your repo, so cadence changes never trigger a redeploy and you can run schedules across multiple PaaS apps from one dashboard. Pricing math, migration playbooks and per-platform trade-offs are on each comparison page below.

FAQ
Common questions on PaaS
- Why not just use my PaaS's built-in scheduler?
- If you only need one of the cadences your PaaS supports and you live entirely inside that platform, the native scheduler is usually the simpler choice. The trade-offs to know: most are UTC-only, none of the major ones support full 5-field cron expressions across the board, and most spin a fresh container per run (Heroku Scheduler in particular). Crontap fits when you want any cron expression, IANA timezones per schedule, or one dashboard across multiple apps.
- Does Crontap save money on PaaS dyno bills?
- Often, yes. Heroku Scheduler bills a one-off dyno per run; Render Cron Jobs are paid services that run on their own. Crontap calls a URL on a service you already pay for (your existing web dyno, your existing Render service) and adds zero per-execution cost. The exact savings depend on cadence: a job that fires every 10 minutes is where the per-execution math starts to matter.
- Can Crontap reach a private PaaS service?
- Crontap calls public HTTP endpoints. The standard pattern is to expose a /scheduled/{job} route on your existing service, protect it with a bearer token sent as an Authorization header, and have your route check the token before doing any work. The endpoint is technically public but the work behind it is gated.
- Will my PaaS's logs still show the request?
- Yes. The request hits your service exactly like any other HTTP call, so it shows up in your platform's request logs, your APM, and your error tracker. Crontap also keeps its own log of the call (status code, duration, response body up to a limit) so you have a scheduler-side record without grepping platform logs.
