Hookbridge vs Svix

Hookbridge is a cloud service for software teams that send webhooks to customer endpoints, receive third-party webhooks or hold incoming events for workers to retrieve through an API. Its send API queues a message and returns an ID, so delivery continues outside the application's request path. Outbound retries use exponential backoff and jitter according to a configured schedule for retryable failures. Retained messages can be replayed from the console or API after successful or failed delivery. Security options include outbound HMAC-SHA256 signatures and inbound checks using configured HMAC signatures, static tokens or IP allowlists. Hookbridge says it encrypts data in transit and uses access controls and monitoring; payload and delivery-log retention depends on plan and customer settings, with automatic purging after the configured window. Developers can use an HTTP API and SDK examples for Node.js, Python, Go, Ruby and PHP. Tools include a CLI tunnel, a GitHub Action for CI testing and an account-free browser request inspector.

Svix is a webhook delivery platform with tools for sending, receiving, streaming, testing, and managing webhook events. Dispatch sends webhooks, Stream handles streaming, Ingest receives events, Portal provides a customer-facing interface, and Play supports testing. Delivery controls include automatic and manual retries, logs and monitoring, filtering, payload transformations, throttling, and multi-tenancy. Customers can give their users a white-labeled portal or APIs to manage endpoints, inspect logs, and view reports. Developers can use SDKs and libraries for JavaScript/TypeScript, Python, Go, Java, Kotlin, Ruby, Rust, PHP, and C#, as well as a CLI, cURL, and a Terraform provider. Destinations include object storage, message brokers, and databases. Deliveries are HMAC-signed under the Standard Webhooks specification, with other authentication options including mutual TLS and OAuth 2.0. Svix is available through API, web, and self-hosted deployments. The Free plan allows up to 50,000 messages per month, 50 messages per second, and seven-day payload retention. Basic costs $20 a month; Professional costs $490 a month. Enterprise pricing is based on needs.
