HookBytes vs Webhooker

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.

Webhooker is an inbound webhook gateway that verifies, stores, and delivers events to your services. It accepts HTTP POST webhooks from providers including Stripe, GitHub, and Shopify, and can check each source using HMAC-SHA256 or SHA1 signatures; invalid signatures receive HTTP 401. For each destination, it makes six delivery attempts over about five hours, with failed events available for resending from a dead letter queue. You can transform payloads per destination, inject headers, and sign outbound requests. A live SSE event stream, delivery history, replay, and in-app or email failure alerts help track processing. Delivery is at least once, so your receiving services should account for duplicates. The cloud service says ingest, storage, and delivery run on Hetzner servers in Germany, with backups in EU data centers. Plans retain events for 14, 30, or 90 days, depending on plan; the data processing agreement is available on paid plans. The Free plan is free, and Pro is €29 a month. Webhooker also offers a CLI for Linux, macOS, and Windows and a Management API for dashboard operations over HTTP.
