A serious-roleplay framework for Open77, the multiplayer platform for Cyberpunk 2077.

OPX//77 gives an Open77 server what a roleplay city needs: characters, money, jobs and gangs, an inventory, vehicles with keys and garages, dealerships and clothing stores, door locks, emotes, phone calls, a HUD, chat and a full staff toolset. It ships as one Open77 resource with a single WebUI, written in Lua and Vue, and built around three rules:

• The server decides. Every request from a client is checked again on the server before anything moves: money, items, doors, vehicles.
• The client stays inside its budget. Open77 kills a client coroutine that runs too long; every hot path is measured by the test suite.
• Never a name to a stranger. A character's name is learnt in roleplay, never shown by the interface.

• Documentation: https://opx77-framework.github.io/opx77_doc/
• Install on a server: Getting started
• Build on top of it: For creators
• Community: Discord
• Support the project: Tipeee

Alpha. OPX//77 runs on a test server and changes quickly; APIs and features may change without notice and it is not yet production-ready. Feedback from operators and players is what moves it forward.

Contributions are welcome: bug reports with journal lines, in-game verification of open items, translations, documentation and code.

• Read the contributing guide and the Code of Conduct.
• Look for good first issue and needs-in-game-test issues.
• Report vulnerabilities privately: see the security policy.
