I doubt that any paying user will be interacting with your system through a browser, but the browser-based demo could do a better job with status. You do show some activity updates, but it would be nice to know where in the overall process the task is. I was just about to bail when my one line C program finished. It took about 90 seconds. Yeah, I am impatient.

Your Lisp implementation would be interesting to me, but I don't know what the market size for a Lisp focused product would be. I actually don't know if the market size for C is great either. We did a huge toolchain refactor at DreamWorks a decade ago and there was a lot of C code, so maybe it would be relevant.

We do have some upcoming changes that will make the status clearer on the website and will be removing some constant time overhead that we're paying on each playground run. I agree that the playground is on the slow side at the moment whilst we're still in the early stages of developing this product.

On the Lisp point, it's not really been developed for commercial reasons, as like you say it's not got the largest market share, but we wanted to see if we could get it to work with languages other than C and Lisp seemed like a nice one to try.

I should add that we believe it’s possible to support other langs too, especially if they compile down to LLVM IR, or have an interpreter/runtime that does. So we plan to eventually work on support for others too like C++, .NET, Java, JavaScript and Rust.
