6 free alternatives to Hook0

Hookdeck Event Gateway's free Developer plan gives you 10,000 events per month, 100,000 discarded requests per month, 3-day event data retention, 1 user, and 5 events per second of throughput per project. It is still a capped free tier, but the monthly event allowance is much larger than Hook0's daily cap, and the product adds observability around failed deliveries and backpressure. That makes it a good fit if you care about inbound event handling, routing, and diagnostics more than Hook0's managed webhook sender flow. No credit card is required. It falls short on Hook0's built-in daily event allowance framing and application-oriented setup. Switch if you want more headroom on event volume with similar webhook infrastructure basics.

• Beats Hook0: 10,000 events per month instead of 100 events per day
• Falls short: Shorter 3-day retention and no application-based free tier structure
• Who should switch: Switch if your main problem is low event volume and you want monthly headroom with observability.

Webhook Relay's free Starter plan includes 150 webhooks per month, secure end-to-end encryption, up to 2 output destinations, 1 input endpoint, 0 bidirectional tunnels, and 0 team members. It is a narrow plan, but it is useful for forwarding webhooks to public endpoints or tunneling them into private services through a local agent. That makes it stronger than Hook0 if your use case is forwarding or tunneling rather than managing webhook applications and subscriptions. It falls short on Hook0's higher event allowance and broader managed cloud workflow. No credit card is required. Choose it if you need a simple relay, test bin, or private endpoint bridge with very limited free usage.

• Beats Hook0: Supports tunneling and destination fan-out for forwarding workflows
• Falls short: Only 150 webhooks per month, which is much tighter than Hook0's 100 per day
• Who should switch: Switch if you need forwarding or tunneling more than a hosted webhook management platform.

Svix's free plan includes Dispatch, Stream, and Ingest, plus an embeddable webhooks UI, connectors and transformations, and a 99.9% uptime SLA. It also gives you 50 messages per second and 30-day payload retention, with no credit card required. Compared with Hook0, Svix is stronger on retention, SLA, and throughput-style usage, and it includes more of the surrounding product surface for debugging and managing webhook traffic. It falls short on Hook0's simpler small-team free setup with explicit daily event and application limits. If your priority is a production-leaning webhook stack with longer payload retention, Svix is the better free option to test first.

• Beats Hook0: 30-day payload retention and a 99.9% uptime SLA
• Falls short: The free plan is less focused on small fixed counts like 1 application and 10 subscriptions
• Who should switch: Switch if you want a more production-shaped free webhook stack with longer retention.

HiveMQ Cloud's free Serverless plan includes 100 connections, 10 GB of data traffic per month, MQTT 3.1, 3.1.1, and 5.0 support, MQTT over TLS/SSL, WebSocket support, and basic support. It is a free managed messaging platform with no credit card required, but it is built around MQTT rather than webhooks. That makes it stronger than Hook0 only if your event pipeline is really message-broker shaped and you need broker connectivity, protocol support, and transport security instead of webhook delivery semantics. It falls short on Hook0's webhook-native features such as event types, subscriptions, retries, and replay. Use it if you are actually building on MQTT, not HTTP webhooks.

• Beats Hook0: 100 connections and 10 GB of monthly data traffic for MQTT workloads
• Falls short: It is MQTT-centric, so it does not replace Hook0's webhook delivery model
• Who should switch: Switch if your backend is broker-based and you need MQTT rather than webhook infrastructure.

Novu's free plan includes 10,000 workflow runs per month, all channels across Email, In-app, SMS, Chat, and Push, US and EU data residency, up to 20 workflows, 2 environments, activity feed retention for 24 hours, and up to 3 team members. No credit card is required. It is stronger than Hook0 when your problem is broader notification orchestration across channels instead of webhook delivery alone, because the free plan covers multi-channel workflows and basic team structure. It falls short on Hook0's webhook-specific tooling, including delivery attempts, HMAC signatures, TLS handling, replay defense, and replay from the dashboard or API. Pick Novu if the webhook is just one leg of a wider notification system.

• Beats Hook0: Multi-channel notification workflows instead of webhook-only delivery
• Falls short: Shorter activity retention and no webhook replay or signing focus
• Who should switch: Switch if you need notifications across channels, not just webhook transport.

CloudAMQP's free tier gives you a shared RabbitMQ broker with a 1 million messages quota per month, 20 connections, max 100 queues for development use, max 10,000 queued messages, and max idle queue time of 28 days. It is a much larger messaging allowance than Hook0's free tier, and it is better when your architecture needs queues, broker semantics, and backlog handling rather than outbound webhook delivery. The drawback is that it is a broker, so it asks you to adapt your application to queue-based messaging instead of Hook0's webhook workflow. Card required is No. Switch if your event handling problem is really message brokering and queue management.

• Beats Hook0: 1 million messages per month with queue and backlog controls
• Falls short: It is a RabbitMQ broker, not a webhook delivery service
• Who should switch: Switch if you need queues and broker semantics instead of webhook endpoints.
