Do you still get this error now?

It's working!

I was excited to hear about this and had a try. It seems it is not possible to jump to the end of the file.

As AI is hot recently, there is also some AI in this tool -- the app icon is made using AI.

Dark mode will be available in a week. The colors are hard-coded currently, but I can make it adjustable.

Is it only for U.S.?

AudioScore is a professional option. There are a few trial for its older versions available on the Internet. But it is not running on Linux.

I created a Postman/Insomnia and a note app for my own use because I do not trust third-party cloud solutions.

I also created a music player because I dislike the shuffle algorithm in Spotify.

And I have created a travel app for my family to provide public transport route suggestions, offline maps and reminders.

My Postman/Insomnia alternative is open-source for the public now: https://github.com/sunny-chung/hello-http

Thanks for the good question. I have tried Bruno. Comparing with mine, it does not support GraphQL subscriptions, WebSocket and gRPC at the moment, which are needed in my daily work. It also does not log the connection detail, which is very useful in infrastructure troubleshooting. It does not persist responses as well, which I would sometimes need that. My application addresses these demands.

Bruno is Postman-like. It only saves when user clicks "Save" explicitly, which I would always forget and causing data loss. Personally I like Insomnia's style more. It saves modification immediately, which is adopted in my application.

My application also features multiple request templates per API, which I could not find an equivalent in existing HTTP client softwares.

Bruno did have something shining which mine does not address yet -- it allows collaboration over git.

Please correct if I am wrong.

Great response, thank you! I think some of those features are pretty valuable (like the other protocols, and the connection logging).

Bruno does allow git collaboration, but all that really means is that its internal markup language (bru, https://www.usebruno.com/bru) is human-readable (and thus diff-able). If your internal save files are similar, they could also be synced in git.

Unfortunately, my application is designed to persist binary requests and responses, so the file format is also binary. Encoding it to a text format is not ideal as it would increase the file size drastically. This is a big barrier and I do not have a concrete direction yet to make collaboration possible in a transparent and easy way.

Can't you store the connection metadata (like a curl request) in plaintext, but binary blobs in git lfs or similar?

Thanks for the suggestion. It seems only plaintext information is interested in most use cases, so this might work. I will consider this solution.

This is an alternative to tools like Insomnia REST or Postman. No account is needed to use this software. No data is shared. No installation is needed. Hopefully its features would be more suitable to users and have fewer usability bugs.

Users can also learn how application protocols operate on HTTP wires through this software.

Images and videos describing this software are available in the project website: https://sunny-chung.github.io/hello-http/

I created this project because my favourite HTTP client softwares all go to cloud and requiring an account to use, also the major bugs were not addressed, e.g. a request collection is deleted unexpectedly by opening a drop down menu.

Please let me know if there is anything missing. This is my first opensource application project.
