Hook0 review
A flexible webhook platform with free, cloud, and self-hosted deployment options.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Hook0 is a webhook management platform for software teams and businesses that send application events to subscriber endpoints. Its REST API handles event delivery, while the platform adds subscription management, delivery logs, event inspection, replay, automatic retries, HMAC-SHA256 signature generation, and label-based routing. It suits teams that need operational visibility around webhook delivery, particularly those choosing between managed cloud hosting and open-source self-hosting.
Pricing gives teams several paths. The Developer plan is free forever for one developer, one application, 10 event types, 10 subscriptions, up to 100 events per day, and seven days of data retention. Startup costs €59 per month and expands capacity to 25 developers, 50 event types, 300 subscriptions, up to 30,000 events per day, and 14 days of retention, while still covering one application. Pro costs €190 per month or €1,824 per year, with unlimited developers, applications, event types, and subscriptions, up to 100,000 events per day, and 30 days of retention. Enterprise adds unlimited everything, custom event volume and retention, a custom SLA, dedicated support, and enterprise security and compliance.
Deployment flexibility is Hook0’s clearest differentiator. The Self-hosted plan is free forever under the SSPL-1.0 license, with users hosting their own instance and receiving community support on Discord. Docker Compose and Kubernetes support make that option relevant to teams managing their own infrastructure. On-Premise Pro provides a dedicated instance in the customer’s environment, up to 1,000,000 events per day, managed updates, and priority email support for €500 per month or €6,000 per year. Hook0 is a strong fit for open-source teams that value control and delivery tooling; teams wanting a simpler hosted-only service may prefer a narrower alternative.
