# kernl

> kernl is a shell that runs small applets in a sealed sandbox. Your identity, contacts, messages and files stay yours; applets borrow them only while you watch.

kernl is alpha software, MIT licensed, built on the open kehto toolkit and the open applet format it hosts. Every page below has a Markdown twin at `index.md` next to it; the links point at the twins.

## Pages

- [kernl](https://kernlize.github.io/index.md): kernl is a shell that runs small applets in a sealed sandbox. Your identity, contacts, messages and files stay yours; applets borrow them only while you watch.
- [Why](https://kernlize.github.io/why/index.md): The five opinions behind kernl, in plain words: one place for your things, a shell that contains applets, protections on by default, many networks, no ranking.
- [Guard](https://kernlize.github.io/guard/index.md): What the kernl guard does between an applet and your network: a sealed sandbox, verified bytes, budgets, flood control and a question before anything destructive is signed, loosened only by you.
- [Messaging](https://kernlize.github.io/messaging/index.md): kernl describes several private-message providers and ranks none. Each is described by what it protects. Private, legacy and ratchet messages work in the live shell when your account can encrypt; ratchet sessions are experimental.
- [Bridges](https://kernlize.github.io/bridges/index.md): Bridges let kernl reach other networks for you. Web fetch and downloads from peers work inside kernl today; newsgroup downloads, sharing and mail hand off to an app on your device.
- [Developers](https://kernlize.github.io/developers/index.md): How to build for kernl: write an applet in the open applet format, learn what the sealed sandbox and strict guard mean for your code, and read the docs first.
- [Shell](https://kernlize.github.io/app/index.md): The kernl shell. Open an applet by its address and run it in a sealed sandbox, with your identity, contacts and messages on loan only while you watch.
