FAQ

Is Lumo open source?#

The extension repositories are public. Lumo does not currently include a license file; Lumo Userscripts is MIT. Read the repository before redistributing a build.

Does Lumo send my pages to a server?#

There is no Lumo relay. Model requests go from your browser to the provider you configure. If you choose a local model, page content does not leave the machine.

Which browsers are supported?#

• Lumo: Chrome and Chromium-based browsers with MV3. A Firefox build is available from source.
• Lumo Userscripts: Chrome 138+ with Allow User Scripts enabled.

Can the agent create userscripts?#

Yes, when you enable the endpoint in Lumo Userscripts and approve the caller. The agent gets list, get and diagnostics immediately; creating, editing, enabling, installing and trashing scripts needs a second Allow writes switch, and every write is audited.

Can I use a local model?#

Yes. Configure an OpenAI-compatible endpoint such as Ollama or a local gateway. Vision and tool calling depend on the model you choose.

Do userscripts run on chrome:// pages?#

No. Chrome does not allow extensions to inject into privileged pages, the Web Store, or other extensions. The manager shows a permission empty state instead of pretending the script ran.

How do updates work?#

Lumo Userscripts checks script updates and asks before installing a version that needs more permissions. Lumo itself updates through the Chrome Web Store or by replacing an unpacked build.

Can I self-host this website?#

Yes. It is a static Vite build. Run npm run build and serve build/client from any static host. Without the Worker that rewrites origins, set VITE_SITE_URL so canonical and social URLs point at your domain.
