In their own words
Convoy
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.
RelayKit
RelayKit is a cloud service and API for receiving, inspecting, verifying, storing, and forwarding webhook events from third-party services. One incoming event can be delivered to multiple destinations in parallel, with each destination tracked and retried independently. Failed deliveries receive automatic retries of up to 20 attempts, and users can replay events manually. Inbound signature verification supports Stripe, GitHub, Shopify, Twilio, SendGrid, Paddle, Clerk, and Resend. Security controls include IPv4 and IPv6 IP allowlisting, configurable rate limits, and audit records for rejected requests. RelayKit says it forwards the original request body and headers, except for specified hop-by-hop headers. The @relaykit/cli can send webhooks to a local development server and requires Node.js 18 or later. Hobby costs nothing for 1,000 webhooks monthly. Pro costs $9 a month for 100,000 webhooks, and Team costs $29 a month for 500,000. Team adds Schema Sentinel, Time Machine replay, and priority support.
