# HookBridge

> HookBridge is a webhook delivery service that handles signing, queuing, retries, rate limiting, and observability so developers don't have to build webhook infrastructure themselves. It supports both outbound (sending webhooks to your customers) and inbound (receiving webhooks from third-party providers). SDKs are available for Node, Python, Go, Ruby, and PHP.

HookBridge provides production-grade webhook delivery with HMAC-SHA256 signing, two-tier retries with exponential backoff and jitter, per-endpoint rate limiting, dead-letter queues, delivery logs with HTTP timing breakdowns, Slack and email alerting, and one-click replay. Inbound webhooks support HMAC, static token, and IP allowlist verification modes.
