VERDICT

Should I use Hook0?

Free webhook platform with HMAC signatures, configurable retries, and delivery monitoring. Self-host the SSPL code or use our EU-hosted cloud. No credit card. - hook0.com

Depends. Buy if you are a developer sending webhooks from your own SaaS and want EU hosting, self-hosting, or a free start. Skip if you need a proven vendor, published security attestations, or no-code tooling.

Confidence

Medium. Based on ~20 public sources; independent user reviews are nearly absent, so reliability judgments lean on official pages and competitor comparisons.
