Convoy vs Webhooker

Convoy is a webhook gateway for sending and receiving events, with automatic retries for failed deliveries. It supports both incoming and outgoing webhooks and can ingest events from Amazon SQS, Apache Kafka, Google PubSub, RabbitMQ, and HTTP. A developer portal lets users inspect deliveries and configure or debug endpoints. Prometheus metrics and OpenTelemetry support provide observability, while separate control-plane and data-plane architecture uses PostgreSQL for event durability. Security features include HMAC signatures, static IPs, IP blacklisting, and replay attack prevention. Convoy is available through web and API access, and can be self-hosted; those deployments keep payloads, secrets, and logs in the customer’s infrastructure. Convoy states that it is SOC 2 and GDPR compliant and offers SSO, SAML, private networking, RBAC, and a 99.999% uptime SLA. The Community plan is free forever for one user and one organization. Premium costs $999 a month, and a 14-day trial is listed. Convoy is headquartered in San Francisco, California.

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.
