Core Pipeline

Four stages. Zero dropped events.

Your webhooks go through four stages. Each runs independently, so a problem in delivery doesn't block ingestion.

Receive

Ingest webhooks from any provider. HMAC signature verification, IP filtering, idempotency deduplication, and 15+ provider templates built in.

  • Stripe, GitHub, Shopify templates
  • HMAC-SHA256 / SHA1 verification
  • IP allowlist filtering
  • KV-backed deduplication

Route & Transform

Content-based routing with 9 filter operators. JSONata transforms reshape payloads before delivery. Topic-based pub/sub for fan-out.

  • 9 filter operators (eq, contains, regex...)
  • JSONata payload transforms
  • Topic pub/sub fan-out
  • Schema validation (reject / warn)

Deliver Anywhere

HTTP, AWS SQS, S3, EventBridge, GCP Pub/Sub, Kafka, RabbitMQ, and WebSocket destinations. Circuit breakers prevent cascading failures.

  • 8 destination types
  • Exponential / linear / fixed backoff
  • Circuit breaker per destination
  • Dead letter queue + manual retry

Monitor Everything

Real-time event stream via WebSockets. Volume, latency, and error dashboards. Auto-created issues on failure. Alert rules with webhook notifications.

  • Real-time WebSocket push
  • Volume, latency, error charts
  • Auto-issue detection
  • Event replay + archival to R2
Global Edge Network

Delivered from the edge.
Every continent. Every region.

hookstream runs on Cloudflare's global network — 300+ cities worldwide. Your webhooks are verified, transformed, and delivered from the nearest edge location to your destination.

  • Sub-50ms median delivery latency
  • Automatic failover across regions
  • No cold starts — always warm at the edge
  • DDoS protection built in

Instant Database

Webhooks become queryable data.

Every webhook payload gets written to a collection you can query. Schema detection, upsert with configurable merge keys, and export to NDJSON or CSV.
