Viewer - Getting Started

The Quale Viewer is the browser-based tool for inspecting evolved connectomes, watching replay simulations, and exploring how brains grow over evolutionary time.

Open quale.run in any modern browser. The landing page shows available experiments as cards with domain badges, fitness scores, and generation counts.


The viewer has three data source modes, selectable from the header tabs:

ModeDescriptionBackend Required
DemosBrowse pre-run experiments hosted on Cloudflare R2. Always available, no setup needed.No
LocalConnect to a quale serve instance running on your machine. See your own evolution results.Yes
SandboxRun experiments on a remote engine.Coming soon

To view your own evolution results:

  1. Run an evolution experiment: quale evolve your-experiment.quale
  2. Start the API server: quale serve --port 8094 --dir checkpoints
  3. Open quale.run (or localhost if running the viewer locally)
  4. Click Local in the header tabs
  5. Your experiments appear as cards - click one to inspect

The viewer auto-detects localhost and defaults to Local mode when accessed from localhost or 127.0.0.1.


The Demos mode shows pre-run experiments with full replay data. Currently available:

Domain filter tabs (All / Survival / Human Factors) let you filter experiments by domain.
