Looking for a Svix Alternative? Open-Source Webhook Platforms Compared
Svix is a good webhook platform, and not the only option. If you care about an SSPL-1.0 license you can self-host for free, EU data residency, or transparent published pricing, this page breaks down the alternatives.
The Short Answer
The best open-source Svix alternative depends on what you need, but for full open-source licensing, EU data residency, and free self-hosting, Hook0 fits. It runs under SSPL-1.0 with no closed add-ons, keeps its data plane on Clever Cloud in France, and bills per event from €59/month. Convoy and Hookdeck each cover part of that, and the table below shows where every option lands.
Why Teams Look Elsewhere
Open-Core Limitations
Svix's MIT base is real open-source. The catch: enterprise features like SSO, advanced analytics, and dedicated support are proprietary. When you scale, you hit a paywall. If your team needs full source access, that's a problem.
$17M in VC vs bootstrapped
Svix has raised $17M in venture capital; Hook0 is 100% bootstrapped and takes no outside funding. The two models answer to different stakeholders, investors versus customers, which is worth weighing when you pick a provider for the long term.
An EU Region Is Not the Whole Story
Svix's managed cloud offers EU and US regions, and its MIT server can run on your own infrastructure. An EEA data processing agreement comes with the Professional and Enterprise plans. Hook0 keeps its data plane on Clever Cloud in France on every plan, free tier included, and publishes its sub-processor list. For a GDPR or data sovereignty review, compare who operates the infrastructure, not only where it sits.
Svix vs the Alternatives
Five webhook platforms side by side. Data speaks louder than marketing pages.
| Criteria | Svix | Hook0 | Hookdeck | Convoy | HostedHooks |
|---|---|---|---|---|---|
| License | MIT (open-core, enterprise closed) | SSPL-1.0 (full source available) | Partial (Outpost Apache-2.0; Event Gateway closed) | Source-available (Elastic License 2.0) | Closed-source |
| Funding | $17M VC-funded | 100% Bootstrapped | $3.5M VC-funded | VC-funded | Bootstrapped |
| Self-Hosting | MIT server, self-managed; supported on-prem on Enterprise | Free (Docker / K8s) | Outpost only (Event Gateway cloud-only) | Yes (self-managed) | No |
| Free Tier | Yes | Yes, no credit card | Yes (10,000 events/mo) | Community edition only | Yes (limited) |
| HMAC Signatures | Included | Included (all plans) | Verification only | Included | Included |
| Retry Logic | Automatic retries | Configurable per subscription (fast + slow phases) | Automatic retries | Automatic retries | Automatic retries |
| Data Hosting | US and EU regions, or self-host | Europe (GDPR) or self-host | US-based | Self-host only | US-based |
| Open-Source Level | Partial (open-core) | Full (SSPL-1.0, no closed add-ons) | Partial (Outpost only) | Source-available (Elastic License 2.0) | None |
Common Questions
Is Svix truly open-source?
Partially. Svix's base is MIT-licensed, but enterprise features (SSO, advanced analytics, priority support) are proprietary and closed-source. This is called open-core. You can run the community edition, but key production features require a paid plan. Hook0, by contrast, ships everything under SSPL-1.0 with no closed-source add-ons.
Can I self-host Svix for free?
Yes, with limits. The Svix server is MIT-licensed and its README documents a Docker and Docker Compose setup anyone can run. The same README notes that some features of the hosted service are not yet in the open-source server, and supported on-prem deployment is an Enterprise-plan feature. Hook0 self-hosts for free with the same feature set as its cloud.
What is the best Svix alternative for startups?
Hook0 works well for startups. Free tier, no credit card, per-event pricing starting at €59/month, and free self-hosting via Docker or Kubernetes. The company is 100% bootstrapped, so there's no VC pushing to raise prices next quarter. Convoy is worth a look too, though it ships under the Elastic License 2.0, which is source-available, like Hook0's SSPL-1.0.
How does Svix pricing compare to alternatives?
Svix offers a free tier, a Basic plan from $20/month and Professional from $490/month. Supported on-prem deployment, SAML/OIDC single sign-on and custom regions sit in the Enterprise plan, priced on request. Hook0 Cloud starts at €59/month with transparent pricing and includes self-hosting for free on any plan. Hookdeck prices per event, with its Event Gateway cloud-only and Outpost self-hostable. Convoy self-hosts for free and sells a managed cloud from $99/month. HostedHooks offers cloud-only paid plans.
Which Svix alternative is both EU-hosted and open-source?
Hook0. Its data plane runs on Clever Cloud in France (inside the EU) on every plan, and the full server is open-source under SSPL-1.0, so you can audit it or self-host it. Svix is open-core, with EU and US regions on its managed cloud; many EU-hosted webhook services are closed and cloud-only. The CDN in front of Hook0 Cloud is Cloudflare (US), disclosed in the public sub-processor list.
Is there a free, open-source alternative to Svix?
Yes. Hook0 is open-source under SSPL-1.0 and free to self-host on Docker or Kubernetes, with a free cloud tier that needs no credit card. Convoy is source-available under the Elastic License 2.0 and self-hostable too, though Hook0 is the one that also offers an EU-hosted cloud if you would rather not run it yourself.
How do I migrate from Svix to Hook0?
Hook0 uses the same webhook building blocks as Svix, namely an event API, per-endpoint subscriptions, HMAC signatures, and automatic retries. You point your producers at Hook0's API, recreate your subscriptions, and switch signature verification to Hook0's secret. Because the server is open-source, you can rehearse the whole flow on a self-hosted instance before moving production traffic.
Is Hook0 production-ready compared to Svix?
Hook0 ships the delivery guarantees you expect from a webhook platform, namely HMAC-signed payloads, configurable retries split into fast and slow phases, and delivery monitoring on every plan. Because the server is open-source under SSPL-1.0, you can read the exact delivery and retry code instead of trusting a claim, and run it yourself for full control. Its EU data plane sits on Clever Cloud in France.
