## When it is useful

Verifying the x-hookdeck-signature header on webhooks delivered through Hookdeck, in Express, Next.js or FastAPI.

## The Catch

Skills MIT. Hookdeck Event Gateway is proprietary SaaS: Developer plan is always $0 but capped at 10k events/mo, 3-day retention, 1 user — over the cap the dashboard locks until you upgrade; Team from $39/mo plus metered events (hookdeck.com/pricing). Only Outpost (and hookdeck-cli) is Apache-2.0 and self-hostable. Only useful if your webhooks already route through Hookdeck.
