Tessera is a desktop library for game assets. It keeps every pack you collect whole, puts its license and where it came from on record, and copies assets into Unity, Godot or Unreal with the credits written for you.
The reason it exists is a question most of us cannot answer: what am I actually allowed to ship? You collect packs for years from bundles, jams, Discord links and stores, and the terms come loose from the files almost immediately. Tessera reads the license out of the pack where it can, keeps a page snapshot and an archive.org copy as proof of what the terms were on the day you got it, and puts anything unclear in Review rather than guessing.
A few things I decided for it:
Your library is ordinary folders. No database you cannot open, no format only Tessera reads. If it vanished tomorrow you would still have everything.
A free, open source library for the game assets you collect. Tessera keeps every pack whole, puts its license and where it came from on record, and sends it into Unity, Godot or Unreal with the credits written for you. Search a hundred thousand files in milliseconds, preview models, sounds and fonts without unpacking anything, and let an AI agent do the filing on your terms. It runs on your own computer: no account, nothing uploaded, and your library stays ordinary folders.
