Open Source Hookdeck Alternatives

Hookdeck provides managed infrastructure for the complete webhook lifecycle, covering both inbound and outbound event traffic. Its Event Gateway ingests, queues, filters, transforms, and routes incoming webhooks from third-party providers, giving teams observability, replay controls, and delivery guarantees instead of hand-rolled receiver code. The platform is built to handle billions of events at production scale, with 99.999% uptime and spike protection to absorb traffic bursts without dropping data.

For outbound events, Hookdeck offers Outpost, a delivery engine for sending webhooks and events from a platform to its own customers’ systems, supporting destinations like webhooks, AWS SQS and EventBridge, GCP Pub/Sub, RabbitMQ, and Kafka. Outpost is open source under the Apache 2.0 license and can be self-hosted or run as a managed service, while the core Event Gateway remains closed-source SaaS. Developers also get a CLI for forwarding webhooks to localhost during local development, a Console for inspecting payloads and delivery attempts, and Radar for monitoring the latency and reliability of upstream webhook providers.

Hookdeck targets developers and platform teams building APIs, SaaS products, or PaaS offerings that depend on webhooks as critical infrastructure. Pricing ranges from a free Developer tier (10,000 events, 3-day retention) through Team ($39/month) and Growth ($499/month, with SLAs and SSO/SCIM) up to custom Enterprise plans with dedicated support and compliance guarantees.
