Axel vs Webhook Management

Axel captures third-party webhooks, routes them to data systems or HTTP services, and replays retained events. It stores an accepted event’s original payload before returning HTTP 202, then delivers it asynchronously. Declarative filters and field transformations can route one event to several destinations. Listed destinations include Postgres, MongoDB, S3, Cloudflare R2, Databricks, BigQuery, and signed HTTP webhooks; generic webhook and custom HMAC sources are also supported. The dashboard and CLI can replay retained events, while Axel Cloud provides 30 days of searchable event and delivery history. Data Contracts infer event and field types and check for schema changes every five minutes, but do not block delivery or guarantee destination acceptance. Delivery is at least once with a stable event ID across retries, so signed receivers should deduplicate. The Free plan includes 10,000 accepted inbound events monthly and community support. Pro costs $20 a month, with additional accepted events at 0.015 USD per 1,000; unused credit expires monthly. Axel is web, API, and self-hosted.

Webhook Management sends and tracks webhooks through a dashboard and REST API. Users can register and test endpoints, route selected event types, inspect deliveries, and replay historical events. Failed deliveries are retried with configurable exponential backoff, and events remain stored until delivery succeeds or they are manually cancelled. Each webhook is signed with HMAC-SHA256 so recipients can verify authenticity and detect tampering. The dashboard tracks delivery success, latency, and endpoint health, with failure alerts; consistently failing endpoints are disabled automatically. The product page states a 99.99% delivery rate and average latency under 200 ms. The API covers endpoint creation, sending and listing events, retrying events, and checking endpoint health. The maker describes use in SaaS integrations, payment events, event-driven architectures, and partner notifications. Starter is free for up to 10,000 API requests per month and includes seven-day log retention. Pro is billed monthly for usage, with unlimited API requests and Webhook Management listed at €0.0001/delivery. The Webhook Management plan is listed at free, starting at $0.0001 per event, with up to five retry attempts included; additional retries are charged. The product lists 30-day retention.
