Vibe coded: this whole project is written by AI (Claude Code).
A GTA Online companion that runs in your browser. Keep it open while you play, and it tracks your businesses, safes and cooldowns, so you know when stock is full or a safe needs emptying.
Status: early development. Not usable yet; see the issues for what's planned.
- Static site, no account. Everything you enter stays in your browser (
localStorage). Nothing is sent anywhere. Export/import lets you back up or move your data. - Time-based estimates. LSOS can't see the game. Business production runs while LSOS is open and tracking ("play time"). LSOS opens paused: press Start once you have loaded into a session, or turn on tracking on open in Settings. Played a while without LSOS? Skip time moves every play-time tracker forward by however long you enter. Real-world cooldowns such as the Lucky Wheel run on the wall clock even when LSOS is closed.
- Sourced game data. Rates and values come from sources such as gta.wiki. Where none exists for your upgrades, LSOS uses a best estimate and labels those numbers "(est.)".
- Overview for a second screen. One page lists what is ready now and what comes next across every tracker, soonest first, with the money waiting. Mark things done right there (sold, collected, spun), hide what you don't care about, and get optional alerts as pop-ups or browser notifications.
- Resync anytime. When an estimate drifts from what the game shows, click the value and type the real one.
- Weekly events (bonuses, discounts, rotations) come from a data file in this repo that's updated weekly, copied from gta.wiki. They're on the Weekly tab.
Targets the current-gen edition (PC Enhanced, PS5, Xbox Series X|S).
