How to choose a webhooks infrastructure tool

Choose Svix when you are offering webhooks to your own customers and want the endpoint portal done for you. Its server is MIT if you would rather self-host.
Choose Hookdeck when the hard part is receiving webhooks from Stripe, Shopify or GitHub reliably, or testing them on localhost. Its Outpost project covers sending.
Choose Convoy for one self-hosted gateway that handles both directions, and check that the Elastic License fits before you build on it.
Choose Hook0 for free self-hosting with a full UI, or an EU-hosted cloud priced by events per day.
Check whether "open source" means OSI-licensed: Svix and Outpost are; Convoy (ELv2) and Hook0 (SSPL) are source-available.
