UpSec is a webhook gateway that never lets you lose a webhook. It sits between senders (Stripe, GitHub) and your app — storing every payload instantly, verifying HMAC signatures, and forwarding with automatic retries using exponential backoff. If your server is down during deployment, UpSec catches and queues everything. Full audit trail, multi-destination routing, and AI-powered anomaly detection included. SDKs for Node.js, Python & Go. Free tier available.
