⚡ 15-minute challenge: build the best thing you can with Elffuss (until Sun 9 Aug)
⚡ 15-minute challenge — build the best thing you can with Elffuss. Open until Sunday 9 Aug 2026.
The rules are simple:
- Open the app (full-screen link is in the README — the folder picker is blocked inside the embedded iframe).
- Give yourself 15 minutes. Ask it for an app, or point it at one of your own folders.
- Post what you got — a screenshot or a clip, plus the prompt you used.
Where to post your entry: as a reply on X or a comment on LinkedIn (links below). The most-liked entry wins, and the winner gets featured here in the Space and in the GitHub repo. You can also drop it in this thread if you'd rather keep it on the Hub.
Worth keeping in mind while you judge what it does: the brain is a ~4B model running inside your own tab (Gemma-4 E4B on WebGPU, or our healed LFM2.5-1.2B where WebGPU isn't available). No install, no account, no API key, and nothing you type leaves your machine — the inference runs on your GPU, not on a server. What lands in the next few months goes far past this, which is exactly why it's interesting to see what today's small local models already pull off.
If you want the engineering underneath — model, runtime, agent harness, editor and filesystem access, all in one browser tab — there are four write-ups here: https://bitacora.utopiaia.com/#elffuss

Clarification on the rules: every like counts, wherever you post your entry — a reply on X, a comment on LinkedIn, or a comment right here in this thread. On Sunday we tally them all together and the entry with the most likes across platforms wins.
So post wherever you're comfortable. If you'd rather stay on the Hub, drop your screenshot/clip and prompt below and it counts the same.
