Svix
What it is
Svix is a webhook service for sending, receiving, streaming, testing, and managing event delivery. Its products cover those tasks through Dispatch, Ingest, Stream, Play, and Portal. Delivery controls include automatic and manual retries, monitoring and logs, event filtering, payload changes, throttling, and multi-tenancy. A customer-facing portal or APIs let users manage endpoints and inspect logs and reports. Developers can use libraries for JavaScript/TypeScript, Python, Go, Java, Kotlin, Ruby, Rust, PHP, and C#, as well as a CLI, cURL, and Terraform provider. Deliveries can reach object storage, message brokers, and databases. Svix supports API, web, and self-hosted deployment, including an open-source server. The Free plan allows up to 50,000 messages per month, at 50 messages per second, with seven-day payload retention. Basic is $20 a month; Professional is $490 a month. Enterprise pricing is based on needs. The service also lists security attestations, encryption, signed deliveries, and regional environments.
