<h1>Spectrum — a step towards <em>usable</em> secure computing</h1>
<p>
Spectrum is a project that aims to create a computer operating system,
based on the principle of security by compartmentalization, that has a
lower barrier to entry and is easier to use and maintain than other
such systems.
<p>
User data and application state will be managed centrally, while
remaining isolated, meaning that the system can be backed up and
managed as a whole, rather than mixed up in several dozen virtual
machines.
<p>
Spectrum is an upstream-first project. Wherever possible, we aim to
participate in cross-project collaboration to move the entire free
desktop ecosystem forward, rather than designing Spectrum-specific
solutions. This reduces the amount of software that Spectrum as a
small project is solely responsible for maintaining, and it derisks
the project — even if Spectrum does not achieve all its goals, our
efforts will have resulted in improvements across the board of free
desktop systems.
<p>
Spectrum is free software, currently under active development. If you
are interested
in <a href="/doc/contributing/communication.html">participating</a>,
we'd love to have you.
<p>
Spectrum is mostly funded through individual donations
on <a href="https://github.com/sponsors/alyssais">GitHub Sponsors</a>
and <a href="https://liberapay.com/qyliss">LiberaPay</a>. Additional
funding is provided
by <a href="https://www.ngi.eu/about/ngi-zero/">NGI Zero</a>, an
initiative by the Digital Single Market of the European Commission.
