IDplayground@agntn/encodings v0.0.0

Any encoding.
Decoded in your tab.

The page imports @agntn/encodings and runs the tool executors right here. Paste the weird string, poke the checksum, break things. Nothing leaves the tab, and every state is a link you can send to a friend who's stuck on the same puzzle.

Tools: 4; same as MCP, Pi and OMP
Encodings: 13; 13 families, 2 with checksum
Network: 0 calls; the library never asks

NoteNothing leaves the tab, but whatever you type does land in the address bar and in any link you copy. A private key decodes fine here. It's still a private key in a URL.

A chip loads the encoding with hello world!. Bech32 needs a prefix, so its chip brings hi.
