Axel
What Axel is
Axel captures third-party webhooks, routes events to databases, warehouses, object storage, and HTTP services, and allows retained events to be replayed. When it accepts an event, Axel stores the original payload before returning HTTP 202, then delivers it asynchronously. Routes can use declarative filters and field transformations, and can send an event to multiple destinations. Listed destinations include Postgres, MongoDB, S3, Cloudflare R2, Databricks, BigQuery, and signed HTTP webhooks; generic webhook and custom HMAC sources are supported. Axel Cloud includes 30 days of searchable event and delivery history, with replay available through its dashboard and CLI. The Free plan costs nothing and includes 10,000 accepted inbound events per month, 30-day event search, and community support. Pro costs $20 a month in usage credit, with additional accepted events billed at $0.015 per 1,000; unused credit expires at the end of the billing month. Axel uses at-least-once delivery with a stable event ID across retries, so signed HTTP receivers should deduplicate. The public source release for self-hosting is being prepared.
