Hook0 Alternatives An Honest Comparison
Looking for a webhook platform? Someone published a "Hook0 Alternatives" page, so here is our side of the story. No spin; just facts, side by side.
The Short Answer
The main alternatives to Hook0 are Svix, Hookdeck, and Convoy, and each solves a different slice of the webhook problem. Svix is open-core with closed enterprise features and $17M in VC; Hookdeck pairs a closed inbound gateway with its Apache-2.0 Outpost delivery engine; Convoy is source-available under the Elastic License v2.0. Hook0 is open-source under SSPL-1.0, bootstrapped, and free to self-host on every plan, with the same code running in the managed EU cloud and on your own servers. The table below puts all four side by side.
Hook0 vs the Alternatives
Four webhook platforms, one table. Judge for yourself.
| Criteria | Hook0 | Svix | Hookdeck | Convoy |
|---|---|---|---|---|
| Open-Source | Yes (SSPL-1.0, full source) | Partial (open-core, enterprise closed) | Partial (Outpost Apache-2.0; Event Gateway closed) | Source-available (Elastic License 2.0) |
| Self-Hosting | Free (Docker / K8s) | MIT server, self-managed; supported on-prem on Enterprise | Outpost yes; Event Gateway cloud-only | Yes (self-managed) |
| Free Tier | Yes, no credit card | Yes | Yes (10,000 events/mo) | Community edition only |
| Pricing Model | Per-event, transparent | Per-event + enterprise tiers | Per-event managed; Outpost self-host free | Flat cloud tiers by throughput (from $99/month); self-hosted Premium $999/month |
| HMAC Signatures | Included (all plans) | Included | Verification only | Included |
| Retry Logic | Configurable per subscription (fast + slow phases) | Automatic retries | Automatic retries | Automatic retries |
| Funding | 100% Bootstrapped | $17M VC-funded | $3.5M VC-funded | VC-funded |
| Data Hosting | Europe (GDPR) or self-host | US and EU regions, or self-host | Canada-based, EU region available | Self-host only |
| Type | Full webhook platform | Webhook platform (open-core) | Webhook gateway + Outpost delivery engine | Webhook platform |
What Their Comparison Page Doesn't Tell You
Hookdeck published a "Hook0 Alternatives" page. We appreciate the attention. Here is what they left out.
"Hook0 is HTTPS-only"
Yes; and that is a feature, not a limitation. Sending webhook payloads over plain HTTP means your customers' data transits in clear text. Every serious production system uses HTTPS. We enforce it because security is not optional.
"No published SLA"
Hook0 Cloud Enterprise includes a custom SLA with dedicated support. If uptime guarantees matter, that is the fastest path; no infrastructure to manage, no ops team needed. Hook0 is also open-source, so you always have the option to self-host if your compliance requirements demand it.
"Pricing is unclear"
Our pricing is public and per-event, starting at €59/month on Cloud with no sales call and no "contact us" wall. For reference, Svix publishes a free tier plus paid plans up to Professional at $490/month, with Enterprise pricing on request (svix.com/pricing, consulted 2026-10-04).
Funding model
Hookdeck has raised $3.5M in VC, Svix $17M, and Convoy is VC-backed; Hook0 is 100% bootstrapped and takes no outside funding. Bootstrapped and VC-funded vendors answer to different incentives, customer revenue versus investor returns, which is worth weighing when you pick a long-term provider.
The Hook0 Difference
One Platform, One Codebase
Hookdeck splits the job: the inbound Event Gateway stays closed and cloud-only, while Outpost handles outbound delivery under Apache-2.0. Hook0 ships sending, retries, signatures and the subscriber portal as one platform, and the code you self-host is the code we run.
No Enterprise Paywall
Every Hook0 feature ships in every plan, and self-hosting the full server needs no sales call. Svix's MIT server self-hosts too, but supported on-prem deployment is an Enterprise-plan feature.
European & GDPR
Cloud hosted in EU. Data sovereignty built in. Bootstrapped; no US VC board deciding your data policy.
Common Questions
What are the best Hook0 alternatives?
The main alternatives to Hook0 are Svix (open-core, MIT core with closed enterprise features, VC-funded), Hookdeck (a Canadian company: the inbound Event Gateway is closed and cloud-only, while Outpost, its outbound delivery engine, is Apache-2.0 and self-hostable), and Convoy (Elastic License 2.0, source-available like the SSPL-1.0 used by Hook0, maintained by frain-dev, VC-funded). Each solves a different slice of the webhook problem. Hook0 is open-source under SSPL-1.0, bootstrapped, and self-hostable for free, with the same code running in the managed cloud and on your own servers.
Is Hookdeck better than Hook0?
Hookdeck is a webhook gateway; it proxies existing webhooks for reliability. Hook0 is a webhook platform; it sends webhooks on your behalf with retries, signatures, and subscriber management. They solve different problems. If you need to add webhooks to your product, Hook0 is the right tool.
Should I use Svix or Hook0?
Both are webhook platforms, but they differ on licensing and funding. Svix is open-core (enterprise features are closed-source) and raised $17M in VC. Hook0 is fully open-source under SSPL-1.0, bootstrapped, and offers free self-hosting. If vendor independence and long-term pricing stability matter, Hook0 is the safer bet.
What does Hook0 cost?
Hook0 has a free tier with no credit card required. Hook0 is also open-source and self-hostable for compliance requirements. Hook0 Cloud adds managed infrastructure, EU hosting, automatic updates, and priority support. Paid plans start at €59/month with per-event pricing.
Does Hook0 work at scale?
Yes. Hook0's architecture supports PostgreSQL-only for simplicity or Pulsar + S3 for high throughput. Cloud customers process millions of events per day. The same architecture runs identically when self-hosted.
