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 with durable SQLite WAL sync. Reusable keep-alive pooling forwards downstream in sub-10ms.
Hardened with PRAGMA busy_timeout = 5000 and WAL concurrency. If your backend fails or throttles (429/500/504), raw payloads are quarantined without SQLITE_BUSY crashes.
Deploy your fix, then click "Replay All Dead-Letter" or use the CLI. Fresh HMAC timestamps and re-computed signatures defeat gateway expiration windows.
At-rest AES-256-GCM encryption with 12-byte random IVs for secrets and webhook bodies. Multi-layer SSRF defense blocks cloud metadata (IMDS) and private ranges.
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 proxy and replay captured webhook events straight into your local server with automatic signature verification.
