Webhook scheduler alternatives
What teams reach for when they need to fire a webhook URL on a cron schedule with a per-IANA timezone. Automatic retries with exponential backoff.
About this topic
Webhooks
Most webhook-receiving tools (Slack, Discord, Make, Zapier, n8n, IFTTT, your own service) accept a POST and run their workflow when one arrives. The missing half is the scheduler: something that fires the POST on cadence, with the right headers, the right body, and the right timezone. Some webhook-receiving tools have a built-in time trigger (Zapier Schedule, Make's Schedule module), and we cover those head-to-head in the automation-platforms category. For tools without one, an external scheduler is the standard answer.
We don't have webhook-specific competitor comparison pages here yet (the closest are the per-platform ones in serverless and PaaS). The blog and use-cases categories cover the webhook patterns (Slack incoming webhooks on cadence, Make scheduled run via webhook trigger, n8n cron-from-outside) and are the right starting point. Crontap is, at its core, a scheduled webhook fire-er: any URL, any cadence (1 minute on Pro), any IANA timezone, custom headers and JSON body. Human failure alerts use connected Notification channels, while machine callbacks remain Integrations. Failed runs are retried automatically with exponential backoff before you get alerted.

FAQ
Common questions on Webhooks
- What's the difference between scheduling a webhook and reacting to one?
- Reacting to a webhook is event-driven: your service receives a POST when an external thing happens. Scheduling a webhook is time-driven: something fires a POST on cadence, regardless of external events. Crontap covers the time-driven half; it doesn't replace your event-driven webhook handlers.
- Can I retry a failed webhook automatically?
- Yes. When a call fails with a server error (5xx), times out, or can't connect, Crontap retries it automatically with exponential backoff, up to 5 times, and only alerts you if the retries are used up. Retries are on by default for new schedules and can be turned off per schedule. Pro lets you tune the number of retries, the starting delay, and whether to also retry on 429 or other 4xx responses.
- How is this different from Make or Zapier's webhook trigger?
- Make and Zapier expose a webhook URL you can POST to and then run a workflow. They are the receiver. The sender (the thing that POSTs on schedule) is what Crontap is. The common pattern is Crontap fires the URL on cadence, Make or Zapier runs the workflow, and you only pay the workflow engine for actual work.
- Does Crontap sign requests?
- Crontap sends the headers you configure on the schedule. The standard pattern is to set an Authorization header (Bearer token, API key) and verify it in the receiving handler. Crontap doesn't currently auto-HMAC-sign payloads (as of Apr 2026), but you can include any pre-computed signed header value in the schedule's headers.
