It looks similar to https://hurl.dev

Hurl is well designed for testing with marchers available for assertions. HTTL only supports strict equality assertions (for now).

Hurl is written in Rust, HTTL in node.

HTTL has an import system that can be useful for reusing an auth setup.

It was funny that when I was in the middle of the project, I discovered Hurl. It was cool, especially since it's written in Rust and uses libcurl under the hood. However, the lack of OpenAPI support and VS Code integration forced me to continue working on HTTL project.
