koigrid vs Svix
Outbound webhooks with HMAC signing and retries — the built-in alternative to Svix and Vercel webhooks.
Svix made webhooks-as-a-service a category: signed payloads, automatic retries, delivery logs. koigrid gives you the same — every platform event delivered to your URL, signed with HMAC-SHA256 and retried with backoff — but native to the platform your resources already live on, at a flat rate and with no per-message bill.
| Feature | koigrid | Svix |
|---|---|---|
| Pricing | Flat rate (included) | Per message / MAU |
| Signed payloads (HMAC-SHA256) | Yes | Yes |
| Automatic retries + backoff | Yes (5 attempts, ~2h) | Yes |
| Delivery history / status | Yes | Yes |
| SSRF protection (no internal targets) | Yes | Partial |
| Events from your infra (apps, DBs, deploys…) | Native | You publish them yourself |
| Manage by AI agent | Native (API + CLI) | API |
What koigrid improves
Native to your events
Every koigrid event (deploys, DB failover, checks…) can fire a webhook — no glue code to publish them.
Flat, predictable
Webhooks are included — no per-message or per-endpoint bill.
Secure by default
Signed with a per-webhook secret and blocked from hitting internal/private hosts (anti-SSRF).
Frequently asked questions
Is koigrid cheaper than Svix?
koigrid is flat-rate with bandwidth included — no per-GB egress or per-request fees. For a comparable setup you usually pay a lot less (see the estimate above).
Can I migrate from Svix without lock-in?
Yes. koigrid runs on portable primitives — standard PostgreSQL, S3-compatible storage and containers — so you can move in (or out) whenever you want.
Is my data hosted in the EU?
Yes. koigrid is EU-hosted (on Hetzner) with data sovereignty by default.
Can I run everything from an API or an AI agent?
Yes — koigrid is API-first and agent-native: every action has an API and a scoped token, with llms.txt and OpenAPI so an LLM can operate it end to end.
