Where Svix's free tier stops
Svix Svix's free tier is not a trial, but it stops at the boundaries listed on the plan itself: no credit card required, 99.9% uptime SLA, 50 messages per second, 30-day payload retention, embeddable webhooks UI, connectors and transformations, and access to Dispatch, Stream, and Ingest. If your workload needs higher throughput, longer retention, or more control than that capped bundle allows, you are already at the point where a different free tier may fit better.

The alternatives
Hook0
FTV 68 / 100Hook0's free Developer tier gives you a fully managed cloud webhook service with 1 developer, 1 application, 10 event types, 10 subscriptions, up to 100 events per day, 7 days of data retention, community support, and no credit card required. It also blocks extra events instead of letting usage spill over. Compared with Svix, it is lighter on built-in product surface, but it is easier to stay within if you want a small hosted webhook setup. The main tradeoff is that the plan is sized for a much smaller project. Switch if you want a simple managed webhook stack and your event volume is modest.
- Beats Svix: No infrastructure to own
- Falls short: Much lower event volume and retention
- Who should switch: Switch if you want the simplest hosted webhook setup for a small project.
Skyvia
FTV 41 / 100Skyvia's free plan is for small-volume integration and automation work. It includes 10k records per month, scheduling once a day, 2 scheduled integrations with 30-day expiration, 1k tasks per month, 2 active automations, 7 days of log retention, 1 GB storage, 5 queries per day, 100 KB traffic per month, 1 endpoint, and 1 connector. It also includes basic integration scenarios, simple mapping, export to CSV, and one-click restore. Against Svix, it gives you a broader integration toolset than webhooks alone, but it is not built around webhook dispatch and ingestion. Switch if your main need is low-volume automation or data movement rather than webhook infrastructure.
- Beats Svix: Broader integration and automation features
- Falls short: Not webhook-specific infrastructure
- Who should switch: Switch if your workload is small data integration or automation, not webhook delivery.
Hookdeck Event Gateway
FTV 69 / 100Hookdeck Event Gateway's free Developer plan includes up to 10,000 events per month, 100,000 discarded requests per month, 3-day event data retention, 1 user, and 5 events per second throughput per project. That makes it a practical hosted intake and delivery layer for webhook-heavy systems, with observability features designed around event handling. Compared with Svix, it is narrower on included retention and throughput, but its event-gateway model may fit teams that care more about ingress, filtering, and debugging than bundled webhook product features. Switch if you want a webhook gateway with observability and your volume fits the free caps.
- Beats Svix: Observability-focused event gateway
- Falls short: Much lower throughput and retention
- Who should switch: Switch if you need ingress, filtering, and delivery debugging in one gateway.
Knock
FTV 70 / 100Knock's free Developer plan includes up to 10,000 messages per month, up to 500 guide active users per month, 500 AI agent credits per month, unlimited notification workflows, unlimited broadcasts, unlimited delivery channels, unlimited team members, batch and delay notifications, built-in multi-tenancy, and Google SSO access. It is a free tier with a lot of workflow and channel flexibility, especially if your use case is customer messaging rather than webhooks. Against Svix, it offers more messaging workflow structure, but it is not a webhook infrastructure product. Switch if you are routing product or transactional notifications and want generous workflow limits.
- Beats Svix: Unlimited workflows and delivery channels
- Falls short: Not designed for webhooks
- Who should switch: Switch if your use case is notifications or engagement messaging, not webhook transport.
Slack
FTV 41 / 100Slack's free tier gives you messaging with 90-day history, 1:1 huddles with audio, video, and screen sharing limited to 30 minutes, Clips for video recording, and integrations with other tools limited to 10 apps. It is obviously not a webhook service, but it can replace some lightweight team coordination and internal workflow needs around webhook projects. Compared with Svix, it has far less relevance to webhook delivery itself, yet it may cover the collaboration layer your team actually needs during development. Switch if your real problem is internal communication and coordination, not event transport.
- Beats Svix: Team communication and collaboration
- Falls short: No webhook infrastructure at all
- Who should switch: Switch if you need a team workspace more than an event pipeline.
EMQX Serverless
FTV 67 / 100EMQX Serverless is a managed MQTT broker with a free offering that includes up to 1,000 connections, a free monthly quota on sessions, traffic, and rule actions, TLS/SSL encryption, basic monitoring and alerts, and 8/5 support. It is built for always-on message brokering, especially in IoT-style workloads. Compared with Svix, it gives you a different kind of message infrastructure with connection-oriented limits instead of webhook-centric controls. It falls short if you specifically need webhook dispatch, replay, or inspection tooling. Switch if your free-tier need is brokered device messaging rather than HTTP webhook handling.
- Beats Svix: Connection-oriented broker quotas
- Falls short: Not a webhook platform
- Who should switch: Switch if you are building MQTT messaging or IoT traffic handling.
Two quick picks
Hookdeck Event Gateway
Hookdeck Event Gateway is the closest drop-in because it is also centered on webhook and event ingestion, with delivery, routing, filtering, and debugging around the same basic workflow. If you are replacing Svix for event handling rather than broader automation, this is the least disruptive switch.
Knock
Knock gives the most free headroom on workflow structure, with unlimited notification workflows, broadcasts, delivery channels, and team members alongside its monthly message cap. If your use case fits messaging rather than webhooks, it leaves the most room before you need to pay.
Frequently asked questions
Which alternative is closest to Svix for webhook delivery?
Hookdeck Event Gateway is the closest match because it stays in the webhook and event-ingestion lane, with routing, filtering, delivery, and debugging features.
Which alternative has the highest free usage limits?
For webhook-adjacent infrastructure, Hookdeck offers 10,000 events per month, while Svix's free plan is defined by 50 messages per second and 30-day retention. For workflow-style messaging, Knock offers unlimited workflows and channels, but it is not a webhook product.
Which alternative has no credit card requirement?
Svix, Hook0, Hookdeck Event Gateway, Knock, and EMQX Serverless all state no credit card required. Skyvia and Slack do not state that here, so their card requirement is unknown from the provided details.
Which free alternative is best if I need more than just webhooks?
Skyvia is the better fit if your actual need is data integration or automation, because its free tier includes records, schedules, automations, queries, storage, and connectors rather than webhook-only features.
Bottom line
For most builders leaving Svix because they need a different free envelope, Hookdeck Event Gateway is the best first stop. It stays closest to the webhook and event-ingestion workflow, so the switch is the smallest, and the free Developer plan still gives you monthly events, retention, a user, and throughput limits that are easy to understand. If you mainly want webhook infrastructure with fewer behavioral changes, start there before considering the more category-shifted options.
