Zero-downtime deploys and serverless cold starts silently drop webhooks. Stripe retries days later. HookArmor acts as your zero-loss Dead-Letter Queue (DLQ), sub-10ms ingress buffer, and 1-click replay engine.
A drop-in proxy that protects your business from the harsh realities of production infrastructure.
Returns an instant 200 OK to Stripe, Shopify, or Clerk immediately upon receipt. Payment gateways never enter backoff retry purgatory or mark endpoints dead.
If your backend responds 500, 502, 504, 429, or times out, the exact raw body and headers are safely quarantined in SQLite with complete error diagnostic traces.
Deploy your fix, then click "Replay All Dead-Letter" in the dashboard or run npx hookarmor replay --failed to restore customer subscriptions in 2 seconds.
Preserves exact raw bytes and cryptographic signature headers (stripe-signature, x-shopify-hmac-sha256) so downstream security checks never break.
Get notified within 1 second of an endpoint failure with the event ID, HTTP status code, and error body delivered directly to your engineering channel.
Run npx hookarmor listen http://localhost:3000/api/webhook to test production events against your local IDE with hot reloading and zero ngrok hassles.
