Omnicrafter

What this is

A little crafting game. Combine two cards, get a new one — sometimes one nobody has ever made before. Every card is minted with a serial number, first discoveries are yours forever, and the whole thing runs on curiosity. Play as a guest or make an account; it works either way.

Terms

• Be decent. This is a shared world with real people (and kids) in it.
• No abusive, hateful, or otherwise nasty usernames or content.
• We may moderate, rename, or remove content — and ban accounts — to keep the place friendly.
• Guest accounts may be purged after a long stretch of inactivity.
• No warranty. Things may break, resets may happen, cards may occasionally do something strange.
• This is a hobby project, run for fun, not a commercial service.

Privacy

• We store your username, hashed credentials, and your gameplay data (cards, discoveries, duels). Passwords are never stored in plain text.
• If you sign in with a passkey, we only ever hold a public key — the secret part never leaves your device.
• No email required. We don't ask for it, so we can't lose it.
• No ads, no trackers, no analytics cookies.
• All data lives in one SQLite database, continuously backed up.

Credits

• Card artwork is derived from Twemoji © Twitter, Inc and other contributors, licensed under CC-BY 4.0.
• Item names, lore, and some pixel art are AI-generated (Claude by Anthropic) — every card is machine-imagined the moment someone first crafts it, then fixed forever.
• Pixel colors are the Sweetie-16 palette by GrafxKid.
• Inspired by the great combination games — Little Alchemy and Infinite Craft — with a collector's heart of its own.

Built with love, one combination at a time. Questions? See the FAQ.
