GUROchan Chat
On August 19th, 2025, Kaguya announced that a new Web chat based on Heyuri's translated version of COMCHAT was added to the site, thanks to kuz and anonwaha. It is hosted at https://chat.guro.cx/.
Remigration to Kokonotsuba
On December 10th, 2025, Gurochan went back to using Kokonotsuba for their backend as opposed to vichan. This is due to vichan being abandoned by it's maintainers, or for atleast the 2 months where there were no commits. There was a bit of friction, as seen in their discussion thread,[1] but seemed to be smoothed out after a few days. Threads and other data was preserved, but some smaller issues such as optimizing for phone UIs and thumbnails from older posts have yet to be fixed.
