We are planning to first open-source our Rust UI framework, and then parts and potentially all of our client codebase. The server portion of Warp will remain closed-source for now.
You can see how we’re thinking about open source here: https://github.com/warpdotdev/Warp/discussions/400 TLDR;
As a side note, we are open sourcing our extension points as we go. The community has already been contributing new themes [https://github.com/warpdotdev/themes]. And we’ve just opened a repository for the community to contribute common useful commands. [https://github.com/warpdotdev/workflows]
Just my thoughts on this: I wouldn't consider using it personally, but would advocate for using it in companies where e.g. there are engineers that work closely with support, teaching them how to debug etc. If it was OSS, I do think it would increase adoption by a lot.
