gtax.dev is a browser-based toolkit for GTA V, FiveM, and RDR2 modding. Preview and convert game files, build clothing and props, paint vehicle liveries, author animations, and package everything into ready-to-use dlc.rpf outputs. No install, free to start, everything runs right in your browser.
Under the hood: a C++ core compiled to WebAssembly, Go services, and a Next.js web app.
