Build on the platform

Egg gives every user a private backend on their own machine: AI, data, identity, and an agent runtime. You build a frontend against one SDK, and the platform provides the rest on the user’s device.

An app on Egg is an Egglet: a web bundle that declares what it uses in a manifest, which the host enforces at runtime. It runs inside the Egg browser or as an ordinary web page in any browser, reaching the local platform over HTTP. The user grants each app access per capability and can revoke it anytime.

Because the model, the data, and the logins live on the user’s machine, an Egg app needs no servers, no API keys, and no inference bill of yours. Heavy or shared work still goes to the cloud; everything personal stays local. That is the hybrid the platform is built for.
