Yes, we are very similar. But we are OSS first. Svix is SaaS first.

We're designing a tool to be flexible and simplify webhooks from a binary perspective. We already support multiple queuing & storage backends, we already support an in-memory queue and on-disk database, so you can run convoy as a single binary without third-party dependencies.

The thesis is if we can simplify webhooks like this, we can do more with a tool like this vs. just for API providers.

Although, I learned they recently open sourced some parts of their backend, but I think that's how we're fundamentally different.
