How does our platform improve the developer experience? The analogy is similar to using a statically typed language vs dynamically typed. Most API tools are dynamically typed. You’re guessing the params and relying on the request to magically work at runtime, only for you to go back to stack overflow or the docs when it doesn’t.

We take the approach of defining parameters and the schema first. When you add a new parameter, you need to mention upfront if it’s required and what type it is (integer, string, boolean). While this can be painful in the beginning, it will save you and anyone you share this with the hassle of understanding how this API works.

Our app is cross-platform on web and desktop. Our desktop app is <20mb and built on top of Rust with Tauri, NextJS, and Supabase. We open source our code because we want to be transparent about how API requests and secrets are handled (all local IndexDB).

I built the first version of this at Robinhood when my colleagues were sharing bash scripts and internal APIs on slack to test things. I wanted to make it easier for anyone to use an API quickly and made use of our OpenAPI specs to generate a nice autocomplete API tool. Soon after, the Options team, then the Crypto team, and then the whole eng org at Robinhood adopted this tool!

Hopscotch is not a Postman fork as far as I know.

You can also do request chaining with Step CI (https://stepci.com) and Hurl (https://hurl.dev)
