What Hacker News says
14 sourceswas using it for a month, cool concept, it borrows stuff from alacritty for the base, added iterm2 inline images protocol, kitty image protocol soon
but there are quite a lot of issues, mainly just really weird ones
1. splits dont feel like splits. unlike in something like wezterm or ghostty, rio uses a literal black line for splits, which cannot be controlled. it doesnt properly resize splits, which you can notice if you have like 4 splits active
2. tabs inherit from the previous tab's zoomed in height and width https://github.com/raphamorim/rio/issues/1196
3. blur doesnt work on window (not that big of an issue anyways) https://github.com/raphamorim/rio/issues/1174
4. some characters are broken (no clue how this happens) https://github.com/raphamorim/rio/issues/1192
5. has issues with iterm2 while using yazi
its a cool concept like i p

I have been waiting to try this out for sometime now. I recently tried various terminal emulator tools and I settled on wave terminal. This is a list of these tools for reference. I would list tools that are on both MacOS and Linux which is comparable to this new emulator. But also because I did not try any on windows.
- Alacritty (https://github.com/jwilm/alacritty)
- waveterminal (https://github.com/wavetermdev/waveterm)
- Hyber (https://github.com/zeit/hyper)
- Kitty (https://github.com/kovidgoyal/kitty)

- Tabby (https://github.com/Eugeny/tabby)

- Contour (https://contour-terminal.org)
- Extraterm (https://github.com/sedwards2009/extraterm)
- Warp (https://www.warp.dev/)
I didn't like that Warp is VC product as I don't like essential tool like a termina

In Rio: Terminal app built over WebGPU, WebAssembly and RustAnyone see how to run it in browser? Would love to try that out.
edit: seems like most of the wasm stuff is some tests within this lib: https://github.com/raphamorim/rio/tree/main/sugarloaf
