Signal Alums Reveal ‘Encrypted Spaces,’ a System for Making Private Collaboration Apps

For years, we have had to choose between powerful collaboration tools and total privacy. Signal alums are now trying to bridge that gap with a new open-source project called Encrypted Spaces.

This system provides a foundation for developers to build apps with features as complex as Discord or Slack. The big difference is that everything is protected by end-to-end encryption from the ground up.

Most of our work currently lives in the cloud, where service providers could technically peek at our data. This project aims to make that impossible by ensuring that only the intended users can see the information.

We are seeing a major shift toward privacy-first infrastructure in the tech world. As more professionals handle sensitive proprietary data, the demand for secure collaboration tools is skyrocketing.

For those of us building in AI or handling client secrets, this is a huge development. It means we could soon have the convenience of Google Docs without the worry about surveillance or data leaks.

This is still early, but it marks a significant step for the open-source community. It moves privacy from a niche feature to a core requirement for the next generation of work apps.
