Just shipped the first non-monitoring feature in Observare: a Stripe webhook logger and replay tool. It's in the existing £5/month plan, no upgrade needed.
What it does:
- You create webhook endpoints in your dashboard, get a unique URL to paste into Stripe
- We verify every incoming event using your signing secret, store the full payload, return 200 (so Stripe doesn't retry)
- Dashboard shows every event in real time — search by type, filter to failures, drill into the pretty-printed JSON
- Click Replay on any stored event → we POST it to your dev environment with a freshly-signed Stripe-Signature header, so your handler validates it exactly like a real event. Or switch to cURL mode and copy a runnable command instead.
- Optional alerts when signature verification starts failing — so you find out the moment your secret falls out of sync, not when the next real event breaks something downstream
The dedicated tools for this exist, but they're separate logins, separate dashboards, separate bills, and the smallest tiers start where solo devs would rather not be paying yet. Bundling it into the £5/month means it's just there when you need it.
Full writeup with the design decisions I'm proud of (parse-before-verify dedup, why we always return 200 even on signature failure, SSRF guard on replay destinations) is on the marketing site:
