Hook0

Description

Hook0 is a source-available webhooks server with a management UI, built by a French company (FGRibreau SARL) and running in production with paying customers. It lets SaaS vendors send webhooks to their own customers, with event management, subscriptions, reliable delivery, automatic retries, HMAC signatures, delivery logs, and a developer portal. You run Hook0 the way your architecture requires. Self-host it on your own infrastructure, including on-premises and EU-based environments, or use the managed Cloud at hook0.com, which runs on Clever Cloud in France. Both models expose the same features, so you can start on the Cloud and move to self-hosting later without rewriting your integration. For European teams, Hook0 is an alternative to US-based webhook services such as Svix and Hookdeck. Your event data stays in the EU or on your own infrastructure, and the vendor operates under French jurisdiction, outside the scope of the US CLOUD Act. The full source code is published under the SSPL v1 (Server Side Public License), so you can audit how delivery works, verify security controls, and self-host the whole stack. Data lives in standard PostgreSQL, which keeps reversibility straightforward and avoids proprietary lock-in. Hook0 fits the sovereignty requirements of regulated industries, public bodies, and any organisation that needs to keep webhook traffic and event data under European jurisdiction. You control where the service runs, who operates it, and how long you keep your delivery history. It reaches TRL 9, a proven technology deployed and operated with real customers today.
