Edron Showcase
Meet Edron through the complete operations console authored with its class-oriented API. The
showcase source uses only edron: no direct Hedron imports, native escape hatches, or component
tree authoring are required. The interactive preview below is generated by edron-sim from that
same runnable source, so its pages, fragments, actions, and styling stay reproducible.
Explore the same app without a server
The preview dispatches the real Edron callbacks at documentation-build time. It uses bounded,
synthetic data and the same Edron-rendered HTML that the runnable app produces.
Command center A complete operations workspace composed from Edron page methods. Everything is operating normally. The transform pipeline is the only active change.

Run the real Edron app
From a repository checkout:
uv sync
uv run uvicorn --app-dir examples/edron-showcase app:app --reload
Open http://127.0.0.1:8000/ . The data is synthetic and local, but the Edron page lifecycle,
sidebar composition, layouts, fragments, actions, charts, tables, tabs, theme, CSRF boundary,
and native lowering are real.
The complete source is examples/edron-showcase/app.py .
Edron's generated theme includes coordinated light/dark tokens that follow the browser preference,
and the request-local shell stacks its layouts for narrow screens.
