Open source developer tools

Expert tech that powers real-time applications. Discover tools that instantly scale your team's capabilities at velocity.

A mission to the future

Real-time applications are at the core of modern experience — and the future of human connection.

But today’s solutions are often stuck in the past: built on outdated and underperforming software that doesn’t meet modern needs. Developers don’t have the tools they require, and users don’t get the experiences they deserve. That’s why we’re building a suite of open source tools to help developers stretch into the future of real-time applications.

Join the expedition

Building our open source developer tools (mission codename: Arcas) is an ongoing project, and you’re invited to join us on the adventure. We’ll be releasing tools and sharing code developments on a rolling basis — try them out and let us know how you put them to use.


A powerful foundation to support optimal performance and actionable insights for real time applications.

In development

Load testing

The first release is ready for action: load testing for up to 100,000 concurrent users. Try it out and let us know what you think.

User analytics

Unmatched observability with advanced insights into your users’ experiences and detailed metrics.
