CoScreen Terminal

A collaborative terminal that lets you pair program with your team securely with near-zero latency

Terminal collaboration

CoScreen, the video collaboration tool for technical teams, now has a built-in terminal that's even better for pair programming and debugging.

Speed: 80% lower latency compared to traditional screen sharing by transmitting terminal content as PTY/text data while still being able to connect without friction.
Multi-user collaboration: Up to 10 users can view the shared terminal and collaborate within it, alongside CoScreen's video chat and multi-display screen sharing.
Annotations: Draw on the shared terminal to highlight code, commands, and output for other participants in addition to easy copy & pasting.
Security: Through the use of data encryption, RegEx pattern matching and entropy-based secret scanning and filtering, CoScreen Terminal enables you to share your terminal more securely.

How to get started

CoScreen Terminal is free for small teams.

Download and launch CoScreen.
Start a CoScreen meeting and invite your team members.
Click on 'Share terminal' in the meeting menu.

‍
🏁 CoScreen Terminal will appear for you and all other participants in the CoScreen session. If you enable remote control in CoScreen, other users can type and click into your terminal.

[data-wf-bgvideo-fallback-img] { display: none; } @media (prefers-reduced-motion: reduce) { [data-wf-bgvideo-fallback-img] { position: absolute; z-index: -100; display: inline-block; height: 100%; width: 100%; object-fit: cover; } }

Give us feedback

CoScreen Terminal is an early version and we're already exploring a couple of additional features (e.g. abilities to disable and fine-tune secret filtering, to scroll up even when filtered, to customize your fonts, or even to bring your own terminal). Please tell us how we can make it better!

Secure collaboration

The data channel of CoScreen is used to securely transmit the encrypted PTY terminal data. If there are only two participants, the data channel produces a P2P, DTLS-encrypted WebRTC data channel connection between the CoScreen peers. If there are more than two participants and as a fallback method for two participants, it relies on a single secure WebSocket connection to the Jitsi VideoBridge via outgoing SSL on port 443, which makes it compatible with most corporate firewall scenarios.

To ensure the protection of sensitive information such as credentials and passwords, CoScreen Terminal has an experimental mechanism to hide suspected secrets before they are transmitted.

Among other components, this feature relies on Sensitive Data Scanner to detect potentially sensitive information in strings that would otherwise be shared with remote users. It is configured to detect various types, such as passwords, private RSA keys, GitHub API keys, tokens, credit card numbers, and social security numbers. When these strings are detected during a terminal sharing session, the scanner will replace it with wildcards before transmission.

Note: secret filtering is an experimental feature that can’t be disabled in this first version of CoScreen Terminal. If you want to share your unredacted terminal, you can still do so via the traditional CoScreen-way: by clicking on the “Share” tab above the terminal window.
