HookBytes vs Hookdeck Outpost

HookBytes provides webhook infrastructure as a managed cloud service or an open-source self-hosted gateway. It creates dynamic endpoints with HMAC authentication and custom routing rules, then delivers events asynchronously with exponential backoff and a dead letter queue for failed deliveries. Users can search, filter, inspect, and replay events through the dashboard or CLI. Stored payloads include event history and metadata such as headers and delivery status. The Open Source plan is a self-hosted Laravel gateway with full source access, an MIT license, community support, and unlimited webhooks at free. Cloud Starter costs $29 a month for up to 100K webhooks monthly, standard support, a 99.9% uptime SLA, email and Slack alerts, API rate limiting, and real-time monitoring. Enterprise has custom pricing, unlimited webhooks, a 99.99% uptime SLA, multi-region deployments, dedicated support, on-premise options, and custom integrations. HookBytes is available through API, self-hosted, and web platforms.

Hookdeck Outpost is outbound webhook infrastructure for platforms sending events to destinations selected by their users. Hookdeck offers a managed service, while the open-source version can run on infrastructure you manage. That version is licensed under Apache-2.0, written in Go, and distributed as a binary and Docker container. Outpost supports event topics, topic-based subscriptions, destination filters based on event content, tenant isolation, and fan-out to multiple destinations. Destinations include webhooks, AWS services, Google Pub/Sub, Azure Service Bus, RabbitMQ, Kafka, Cloudflare Queues, and Hookdeck Event Gateway. Delivery is at least once, so consumers should deduplicate events by event ID. Failed deliveries retry automatically with exponential backoff by default, with customizable schedules and manual retries through the Retry API, tenant portal, or Admin UI. It supports webhook signatures, Standard Webhooks compatibility, secret rotation, destination-failure alerts, optional automatic disabling of failed destinations, and OpenTelemetry metrics. Self-hosting is always free; managed Starter is $10 a month, and Growth is $499 a month.
