Overview
Hook0 is a webhooks-as-a-service platform: your application POSTs an event to its REST API and Hook0 handles routing to subscribers, retries, payload signing and TLS. Subscribers can register several endpoint URLs, pick event types and filter by labels. Every attempt is logged so deliveries can be inspected and replayed.
- Best for
- SaaS teams that need to send webhooks to their customers without building the delivery layer
- Pricing
- Free Developer tier, then €59/month (Startup) and €190/month (Pro, or €1,824/year), with custom Enterprise pricing and per-event overage above the daily quota.
- Runs on
- WebSelf-hosted

- All delivery attempts logged, searchable and replayable
Trade-offs
- Free tier caps at 100 events/day and 7 days retention, extras blocked

- On-premise pricing is behind a separate tab, not shown here

How this score is made up
Each dimension is scored out of 100 and combined into the headline score using fixed weights.
MCP support
Whether an agent can drive the product through the Model Context Protocol, and how much setup that takes.
API quality
Public API surface: machine-readable spec, official SDKs, documented auth, errors, rate limits and versioning.
Documentation
Publicly reachable docs — coverage, freshness, code samples and machine readability.
Agent friendliness
How readable the site is to an automated client: llms.txt, structured data, server-rendered content, crawler access.
Pricing transparency
Whether real prices are published, self-serve signup exists, and usage costs are knowable without a sales call.
Changelog
A public, dated record of what shipped and when — the clearest signal that a product is still alive.
Marketing site structure
Whether the site answers a buyer's questions: clear positioning, the pages that matter, and accessibility.
Page speed
How fast the site loads for real visitors: Chrome UX Report 75th-percentile LCP, INP and CLS, with a Lighthouse mobile run standing in where a site has too little traffic for field data.
Operational trust
Status page and incident history, security disclosure, compliance and data-processing documentation.
Measured, but not part of the score
Useful to know, but not a mark for or against the product — so these do not affect the ranking.
Openness
Source availability, self-hosting, data export and open standards. Scored and shown, but not part of the composite — paid SaaS is not worse for being paid SaaS.
Maintenance
Release cadence and repository activity. Scored and shown, but not part of the composite — it is only measurable for open repositories.
