About this app

Made for a clear purpose.

Hookverge is a private webhook-resilience lab for backend developers, platform engineers, consultants, and integration owners who need to reason about duplicates and partial failure before production traffic does it for them.

Explore how event rate and provider failure translate into duplicate pressure, retries, backlog, and recovery obligations.

KEY FEATURES - Retry-decay visualization - Event-rate and failure sensitivity - HMAC-SHA256 local fixture - Idempotency-window register - Persist-before-ack checklist - Dead-letter and replay ownership - Resilience artifact export - No endpoint or server required - Native structured-file or CSV import - Local PDF, workspace JSON, and domain-artifact export - 48 original offline technical reference plates - No account, ads, analytics, tracking, IAP, or subscription

Hookverge models recorded rates, attempts, and dedupe windows and generates local fixtures; it does not receive, send, replay, or validate production webhooks. Verify provider-specific signing, timing, ordering, retry, and recovery behavior against current documentation and controlled tests.
