Runs in your browser with Pyodide. Assembly uses MCJIG, colours come from the Minecraft 26.3 client, then 26.4 snapshot 6. Anything newer is drawn magenta and listed in the report. Your pack is never uploaded. Each build is counted for the table above: a pack from a Modrinth link by its name and pack.mcmeta basics, a dropped file or any other link by number only.
