Precision webhook scheduler for indie hackers — $15 founding

Lambda can't hold long delays; a broker is overkill for one HTTP call. SendItWhenever fires a signed webhook at the exact second you schedule it — with Early Firing to offset round-trip latency. · Three lines of SDK (Node or Python) · HMAC-signed delivery + Encryption at Rest + SSRF protection · Retries, dead-letter queue, searchable delivery log · Free to start — Indie plan at $15/mo founding price (first 50; $19 after)
Hey Product Hunt 👋
I built SendItWhenever because every time I needed to fire a webhook later — a trial expiry, a deferred charge, a follow-up ping — my options were bad: serverless functions time out long before the delay, and standing up a real message broker is a weekend of IAM and YAML for one HTTP call.
So this is the small, dependable thing I wanted: schedule({ url, fireAt, payload }) and it fires on time, HMAC-signed, with automatic retries and a searchable delivery log.
A few things worth knowing:
→ The live demo on the landing page (/#try) fires a real signed webhook — you can watch the scheduled → fired → delivered timeline and inspect the actual X-SendIt-Signature header. No signup.
→ Precision is second-level with Early Firing (best-effort RTT offset) — I'm honest about that at /status where you can see the real on-time numbers.
→ Node and Python SDKs are both published. What language should be next?
Launch pricing: 1 month free, then $15/mo locked for life — for the first 50 founders. After that it's $19/mo. No per-request billing ever.
Happy to dig into any of the architecture (Redis/BullMQ fire path, fire-time SSRF re-resolution, AES-256-GCM payload encryption). Thanks for taking a look 🙏
