Hook0 is an open-source, bootstrapped webhooks platform with free self-hosting, EU cloud hosting from 59 euros/month, and no vendor lock-in.
Hook0 is an open-source webhooks-as-a-service platform founded in 2022 in France. It lets developers add outbound webhooks to their product with a single API call, while Hook0 handles the deliverability, retries, and security work behind the scenes.
Unlike many closed-source webhook providers, Hook0's code is published on GitHub under the SSPL-1.0 license, and the company is fully bootstrapped with no venture capital funding, positioning itself around long-term independence and no vendor lock-in.
Hook0 handles the operational complexity of webhooks: configurable retry logic for failed deliveries, HMAC signatures and TLS encryption for security, and an event logging and monitoring dashboard so developers can see delivery status at a glance.
Because the platform is open source, teams can self-host it for free with full control over their data, or use Hook0's managed cloud service, which is EU-hosted and GDPR compliant, without being locked into a single deployment model.
Hook0 offers a free, self-hostable Developer tier and a free cloud tier for up to 100 events per day. Paid cloud plans start with Startup at 59 euros/month for up to 30,000 events per day and 25 developers, rising to Pro at 190 euros/month for up to 100,000 events per day with unlimited applications and developers.
For organizations that need a dedicated environment, Hook0 also offers a managed dedicated instance starting at a 1,000 euro setup fee plus 500 euros/month, alongside the option to self-host the open-source code entirely for free.
