Holo Web Conductor

What is Holo Web Conductor and what is it for?

Holo Web Conductor is a browser extension that runs Holochain applications in a web page without the visitor installing Holochain software. It keeps the visitor's keys in the browser and runs the application's own logic there, while a relay service handles the shared network side.

Holochain applications are peer-to-peer, so each person taking part normally has to install and run a conductor — the software that keeps their keys, runs the application's logic and talks to the network. For people who simply want to open a web address and start using an app, that requirement is a barrier. Holo Web Conductor is an attempt to remove it.

It is a browser extension that acts as the visitor's own conductor. It creates and keeps the visitor's cryptographic keys inside the browser, runs the application's compiled logic locally, and signs the actions the visitor takes. The part a browser cannot do well — holding shared data and staying online for other people — is left to a separate relay service. Web apps reach the extension through a companion client library.

An app built for it can try the extension first and fall back to an ordinary Holochain connection when the extension is not installed, so one page can serve both kinds of visitor. Running it in production means hosting the application bundle and relaying network traffic through a linker, optionally adding a joining service that handles onboarding. The project's own guides for application developers and for deployment are the place to start.
