Hostedhooks vs Hook0

Hostedhooks is a proprietary webhook platform. It has fewer features but is quick to set up. Hook0 is open-source and does more on multi-tenancy, event routing, and self-hosting.

Open-source vs proprietary​

This is the main difference. With Hostedhooks:

  • You can't inspect the source code
  • You can't self-host it
  • You can't customize the behavior
  • If Hostedhooks shuts down, you need to rebuild or migrate
  • You have no visibility into how your data is processed

With Hook0:

  • Full source code under SSPL-1.0
  • Self-host on your own infrastructure with zero feature restrictions
  • Fork and customize if needed
  • The only restriction: if you offer Hook0 as a managed service to others, you must open-source your entire stack
  • Your infrastructure runs independently of Hook0 the company
  • Audit every line of code that touches your data

In regulated industries (finance, healthcare, government), self-hosting and code auditing are requirements.

Where Hook0 goes further​

Hostedhooks covers the basics: send a webhook, check delivery, retry on failure. For simple use cases, that works.

Hook0 adds:

  • Event type hierarchies: events organized as order.created, order.updated, order.cancelled instead of flat strings
  • Label-based filtering: route events to subscriptions based on arbitrary key-value labels (useful for multi-tenant SaaS)
  • Dead letter queue: failed events are kept for inspection and replay, not silently dropped
  • Biscuit token authentication: capability-based access control with Service tokens for programmatic access, instead of all-or-nothing API keys

Pick Hostedhooks if​

  • You need a quick webhook setup with minimal configuration
  • Your use case is simple: a few event types, a few endpoints
  • You don't need self-hosting or source code access
  • You want the smallest possible tool for the job

Pick Hook0 if​

  • You need self-hosting (compliance, data sovereignty, air-gapped environments)
  • You're building a multi-tenant SaaS platform
  • You need event routing and filtering beyond flat event types
  • You want open-source with no vendor lock-in
  • You need dead letter queues and manual replay
