Frequently asked questions
What is the main difference between Hook0 and Zen Mesh?
Hook0 is an open-source Webhooks-as-a-Service (WaaS) platform for sending webhooks from your application to subscribers. Zen Mesh is a private webhook delivery platform for receiving webhooks from third-party providers (Stripe, GitHub, Twilio, etc.) and delivering them into private or internal services without opening inbound firewall access.
Can Hook0 deliver webhooks to private networks?
Hook0 delivers webhooks to publicly accessible endpoints. It does not provide a private delivery mode for reaching services behind NAT, VPN, or corporate firewalls without inbound access. Zen Mesh is designed for this use case with its outbound-only delivery model.
Can Zen Mesh send webhooks to subscribers?
Zen Mesh focuses on inbound webhook delivery — receiving webhooks from providers and delivering them to private services. It is not a platform for sending outbound webhooks from your application to your customers' subscribers.
Is Hook0 open-source?
Yes. Hook0 is fully open-source under the Server Side Public License (SSPL-1.0). The source code is available on GitHub. Hook0 also offers a managed cloud version hosted in Europe.
Does Zen Mesh have provider templates for webhook sources?
Yes. Zen Mesh provides Provider Template Packs for common webhook sources such as Stripe, GitHub, Twilio, Shopify, and custom sources. These templates include signature verification, event classification, and delivery routing defaults.
