My experience with bolt.diy on a M3 Macbook: it is not usable anymore.
bolt.diy declined over the last updates and from my point of view it is not usable anymore.
Even with the most sophisticated LLMs (through openrouter or api) it is not able to do a simple task. Also the preview isn’t used only if you now how to “update” the vite files or something similar but results are very bad.
As stated in other topics here it is totally slow and very often doesn’t respond at all also stopping the hole machine only a restart helps.
Do not use it or try it anymore, sorry to have to say that.
What is your experience?
