WebhookWarden

WebhookWarden is a web app (with optional CLI) that monitors, validates, and replays webhooks across your integrations. It sits between webhook producers and your endpoints (or mirrors traffic via gateway/log drains) to detect schema drift, signature mismatches, latency spikes, and silent delivery failures. The product provides contract tests for webhook payloads, automatic alerting with actionable diffs, and a safe replay queue so developers can reprocess missed events without asking vendors to resend. It also includes per-integration dashboards (Stripe, Shopify, GitHub, etc.) that highlight breaking changes and show real delivery rates by endpoint, region, and status code. This is not a generic “API monitoring” tool; it’s narrowly focused on the messy reality of webhooks: retries, idempotency, signature verification, and payload evolution. Pricing is usage-based by events monitored and retained.
