Desktop
Application windows share one environment. The public Extella demonstration shows several tools on the same desktop.
Section 05 / Software
Extella OS
Opens applications on a shared desktop.
A desktop, applications and a store built on the Extella core. Tools become familiar windows and workflows.
Why it helps
Work with several applications in one environment, open existing tools and return to the setup you built.
What it contains
Applications and store
An application gives a program an interface. The store helps people find and install available tools.
Evolution Console
The platform map includes a console for work on agent evolution. Agent development remains a separate direction marked as work in progress.
KV Store
The key-value store holds data used by tools. Each program defines its data structure and access.
What was measured
Extella measurements, September and October 2026. Each number holds under the conditions given.
- App text updates for everyone without reinstalling.
The Extella Guide app reads its text from the repository. A text edit shows up in an open window within 5 minutes, which is how long GitHub keeps its copy (checked 13.08.2026).
- A new expert arrives only with a reinstall.
An app's agent is a copy of the expert set at the moment of installation. To get a new expert, remove the app from the desktop and install it from the store again.
- The window opens ready-made browser apps.
An Extella OS window shows another party's browser app of up to 20 megabytes and up to 500 files. The window runs in a sandbox without browser storage (localStorage), so an app that keeps data there needs a shim (02.10.2026).
- Microphone and camera are not available in the window.
The window sandbox rejects an access request the same way as a person pressing «Block». An app in a window accepts a ready recording file instead (20.08.2026).
