About Webhook Relay
Webhook Relay gives you an endpoint that receives webhooks and delivers them to a public URL, a server on a private network, or your own localhost, with durable retries when the destination is down. Functions written in JavaScript or Lua can filter, reshape and fan out payloads.
A relay CLI handles forwarding and tunnels, and there are connections to AWS SQS, Google Pub/Sub and Azure. The free plan covers 150 webhooks a month. It suits developers who need webhooks to reach machines that are not publicly reachable.
