Webhook scheduler alternatives
What teams reach for when they need to fire a webhook URL on a cron schedule with retries and a per-IANA timezone.
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, retries on 5xx, and failure alerts to email or your team's chat.

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. Crontap retries on configurable failure responses (5xx by default). If the receiving end returns 502 once, Crontap retries with backoff before declaring the run failed and firing your alert. The retry policy is per-account, so a quick recovery doesn't page anyone.
- 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.
