A Svix alternative without a separate service

Svix is a good webhook service. If you'd rather not add a vendor or run another server, and your app is Node.js on Postgres, Hookgres gives you the sending side as a library that uses your existing database.

How they differ

	Hookgres	Svix
What it is	A TypeScript library	A hosted API, or a self-hosted Rust server
Where it runs	Your app, your Postgres	Their cloud, or your server plus Postgres (Redis optional)
Part of your database transaction	Yes	No, a separate API call
Signatures	Standard Webhooks	Standard Webhooks
Retries	About 28 hours, configurable	Yes
Delivery log	Rows in your database	In their dashboard and API
Customer portal	Build on the delivery log	Included
Price	Free, MIT	Free tier, then per message or plan
Languages	Node.js / TypeScript	SDKs for many languages

When Svix is the better choice

• You want a hosted customer portal today.
• Your backend isn't Node.js, or several services in different languages send webhooks.
• You'd rather not have webhook traffic touch your database.

When Hookgres is the better choice

• You want webhooks to commit with your data, with no outbox to build. With any external service, a crash between "saved" and "sent" loses the event.
• You don't want another service, vendor or subprocessor. Payloads and logs stay in your database.
• You want to query deliveries with SQL, for support or a customer-facing log.

Switching

Both use Standard Webhooks signatures and whsec_ secrets, so receivers keep working. The migration guide maps every concept and call.
