Nice job. How are you handling outpainting? Outside of using an open-weight model, I imagine it's going to get pretty expensive quickly with something like NB or GPT-Image.

Feedback:

Add an option to hide user tags and only show the different colored mouse cursors otherwise the view will probably get cluttered quickly.

Right now it's AI with a human doing the curation. I'll def have to figure out how to do it just with AI, as the current user load is going to finish all the pre-baked levels in the next 30 minutes.

Yeah I hear you. I’ve done some experimentation with infinite image generation, and it’s very difficult to pull off without some level of human supervision.

Even if a model can technically generate infinite content, you’ll find that it eventually repeats certain patterns, so the results can start to feel very repetitive over time.

If you do end up going with a cheaper open‑weight model, Flux Klein 9B might be your best bet as it’s fairly decent at handling outpainting [1].

Thanks, I'll definitely look into it.

Please talk about the development. How long did it take you? Language/framework? 100% agentic (if so, which LLMs did you use, and for what)?

It's about 90% vibe coded with claude opus 4.8 (and now 5).

Fun, but suggestion - don't let the nametags cover the piece area. Very frustrating to not even be able to see the pieces because people are hovering their cursors there.

I love it so much, it felt really good when I placed my first piece :). There are some technical issues, the UI and controls could be better, but it definitely was fun, and that's what really matters!

Thanks! If you have any suggestions please let me know!

Nice concept. 6 people, it was fun, 18 people, not so much. Can't imagine a few hundreds, prolly pure chaos.

Maybe different people seeing different pieces from different sides would help with the chaos, idk.

Ya I was thinking maybe cap it at 12 people, and then if you join it starts fresh as level 0?

The game does not work - I do not see any puzzle pieces

Sorry, hit some cloudflare limits faster than I thought would happen. Working now.

Woah, great concept but too many cooks in the kitchen. Lots going on and it would benefit smaller lobbies. Otherwise awesome.
impostervtJul 26, 2026, 9:47 PM
Ya may need multiple rooms, capped at some number of users.

Fun, it's a good idea to play jigsaw online with others together

Somebody ban me forever on this game, even at my best I am sabotaging other's game.

sorry, hit the cloudflare worker cap for a free plan. Just upgraded.

I love art, and I have a particular weakness for the style of art you're using for the project. Not sure if you'd give a fig, but I have bookmarked it just to watch. I guess there will always be something new, and live humans are there, organizing the image in real time. As an outlier and unintended fan, I appreciate your work.

Edit: I should say that I left films such as Arrietty and other Japanimations (Kaguya, Fireflies Grave, Spirited Away) I can't recall, wanting to return and stay there. I guess on occasion, this might help.
