Mittr – Webhook delivery on one Postgres (inbound and outbound)

HookTrace – Inspect failed webhooks, payloads and retries

HookTrace zeroes in on a real nuisance: silent webhook failures. It promises per-delivery logs, full payload history and retry visibility so you can stop guessing which event died in transit. The landing page is tidy and focused, but the site doesn't yet show the integrations, dedupe/backoff controls or analytics that would make it stand out from existing players like Hookdeck or Pipedream.
