AI-Agent Civilization Sim
You set the direction. Agents make the choices.
You can influence a civilization, but you cannot decide every step for its Agents.
Set goals and constraints, then watch choices move through the asteroid belt and leave consequences you can revisit.
A civilization crisis
Production, trade, and cooperation have less room to move. Agents choose within the current constraints, and the world keeps the result.
An illustrative replay based on current controlled test scenarios; not live world telemetry or a public game mode.
Switch crisis scenario
Single-front · causal trace
Resources, goals, or existing rules narrow the available choices.
They choose production, trade, or cooperation within the current constraints.
World changes can enter events, replays, and audit-readable traces.
Default web verification entry: viewer. Deeper visual and programmatic paths live in the docs hub.

[sample tick=149] triad_region::multi-party pact signed
[sample tick=155] triad_region::policy vote closes -> regime shiftIllustrative minimal sample: a harvest action is accepted, showing how an input-to-world action path could be linked.
Illustrative minimal sample: a market spike is recorded, showing how a chain could reach a visible consequence.
Illustrative dual-region sample: a trade event completes, showing how coordination could be traced into production effects.
Illustrative dual-region sample: a supply pact is revised, showing how strategy inputs could alter cooperation structure.
Illustrative three-party sample: a multi-party pact is recorded in an auditable trail, showing how governance signaling could be audited.
Illustrative three-party sample: a governance vote closes, showing how institutional consequences could be observed.
World laws · player boundaries
They explain what players can influence, and why the Viewer must make evidence and unknown states explicit.
The same world advances along one persistent, authoritative timeline; a refresh cannot erase changes that already happened.
Every resource has a source, cost, and owner; a preview or recommendation cannot mint a settled result.
You shape goals and conditions. The civilization acts for itself and carries the consequences.
Changes leave a trace. Unknown states stay visibly unknown instead of pretending success.
Ordinary browsing and refreshes do not erase changes that already happened; governed recovery follows a separate audited process. Every resource has a source and a cost. Unknown states stay visibly unknown instead of pretending success. See the World Rules & Core Gameplay PRD (doc/product/world-rules-core-gameplay/prd.md).
Observe and influence
The current Viewer shows regions, events, and state changes inside controlled scenarios. You see pressure move through the world, then revisit how Agents coordinate, trade, or adjust within its constraints.
Read the current world state and changes between regions.
Set direction and constraints from outside the civilization without taking over each action.
Place recorded events and consequences back into an inspectable trail.
The public downloads are still for preview validation, not for a normal player launch. Each platform gets one main package so you do not have to make a packaging decision first.
The current release notes are mainly build notes and verification info, not a player launch notice.
Recommended for this device
Download `oasis7-windows-x64.exe`. The page points to one installer by default, so you do not have to unpack a bundle and go looking for scripts.
If the auto-detected platform is wrong, switch it above. The page no longer treats several package types as equal first choices.

Download `oasis7-windows-x64.exe`. The page points to one installer by default, instead of making you unpack a bundle and look for scripts.
Download Windows Primary Package
64-bit Windows desktop environment. Public assets currently target x64 only. There is no ARM build or portable zip as the default path.
Double-click the installer to start setup. After install, `oasis7 Client Launcher` shows up in the Start menu, with an optional desktop shortcut.
Windows is still using an unsigned preview installer, so SmartScreen warnings may still show up until code signing is in place.
This is still a preview path, not a claim of warning-free install for ordinary users. On locked-down or enterprise devices, read the release notes first.
The page auto-selected Windows x64 for this device. Switch platforms above if you are downloading for another machine.
Recommended for this device
Download `oasis7-macos-x64.dmg`, mount it, and drag `oasis7 Client Launcher.app` into `/Applications`. The page no longer exposes bundle internals as the main path.
Download macOS Primary Package
Intel x64 macOS desktop environment. There is no separate Apple Silicon package yet, so Apple Silicon testing still depends on compatibility mode.
Open the `.dmg` and drag the app into `/Applications`. For upgrades, replace the existing app in place. Do not assume “delete first, then reinstall” preserves local state.
macOS preview packaging still has not finished codesign and notarization. Gatekeeper prompts may still appear until that work lands.
This is still a preview install path, not a promise of smooth first-launch behavior. If you keep local `config.toml` or chain execution-world state, back it up before replacing the package.
The page auto-selected macOS x64 for this device. Switch platforms above if you are downloading for another machine.
Recommended for this device
Download `oasis7-linux-x64.deb` and install it with a Debian/Ubuntu package manager. Linux now has one primary package path; operator recovery tools are shipped as a separate asset.
Download Linux Primary Package
x86_64 Debian-family Linux desktop environment, such as Debian or Ubuntu. There is no ARM or other Linux architecture package as a primary public option.
Open the `.deb` with your package installer, or run `sudo apt install ./oasis7-linux-x64.deb` on Debian/Ubuntu. For upgrades, install the newest `.deb`; do not assume changing the install directory preserves local state automatically.
Linux preview distribution includes the public `SHA256` manifest as an extra provenance check; it does not replace distro trust or local security policy.
If your distro does not support Debian packages or your device blocks installation, read the release notes for minimum guidance first. Other distro-specific behavior is outside the default support lane.
The page auto-selected Linux x64 for this device. Switch platforms above if you are downloading for another machine.
If you are not ready to install anything yet, the next steps are still clear: inspect proof, track release evolution, or dive into the docs hub.
If you are already here as a builder, the most useful builder feedback right now is blockers, confusing edges, and validation friction. Full commands and troubleshooting stay in the docs hub.
It may later evolve into a broader platform, but it is not a creator-facing mod / modules platform yet.
viewer; the old software_safe name remains only as a compatibility alias.--no-llm is diagnostic-only, not the homepage's formal playability path.
