In their own words
Axel
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.
