A free, open-source Pax Historia alternative
Open Historia is an open-source AI grand-strategy experiment playable in the browser: command a nation in plain English, keep long-running campaign memory, and bring your own AI provider or play through the shared free gateway.
Why players look for alternatives
Pax Historia is a hosted AI sandbox platform where scenario play runs through its own service. Open Historia takes the same idea in an open direction: MIT-licensed code, browser play with local saves, and your choice of AI provider — including a local model — instead of a metered credit system.
What you get today
Natural-language turns adjudicated by an AI Game Master, 20+ historical and alternate scenarios, a living world map, diplomacy threads, and a rewindable timeline that can branch into alternate histories. Cloud saves are optional and require sign-in.
Where it is honest about its limits
Open Historia is a held experiment, not a polished platform: the map detail and campaign pacing are prototype-grade, and there is no multiplayer or community scenario marketplace yet.
