CoScreen

CoScreen provides real‑time, multi‑user screen sharing that lets participants view and control one or more application windows across several displays with a single click. The platform emphasizes low latency and high visual fidelity, aiming to make remote collaboration feel as if users are working on the same machine. It includes a shared terminal for collaborative command execution and debugging, as well as integrated audio and video chat with flexible layout options.

The tool is targeted at technical teams—engineers, product designers, and developers—who need to pair program, troubleshoot code, or review designs together. It supports remote and hybrid work environments and is positioned for use in engineering workflows that involve IDEs, browsers, and other desktop applications.

Distinctive aspects include the ability for multiple participants to control shared windows simultaneously, side‑by‑side multi‑display sharing, and a focus on security and data privacy while maintaining fast, high‑quality media streams. The macOS‑only stable release is offered by Datadog.
