OP here - CoScreen offers multi-user screen sharing and simultaneous remote control for engineering teams like no other solution out there.
After the awesome reception on HN a year ago, we're super excited to announce our completely newly designed & developed v1.0 release of CoScreen for macOS and our private alpha for Windows.
Today's video chat solutions are great if you enjoy awkward full-screen conversations, but are a productivity killer for development teams. The pandemic has turned endless, boring in-office meetings into endless, boring video calls. It’s also just too painful for engineering teams to wrangle with complex pull requests using a brittle string of tools like Zoom, Skype, Tmux, GNU screen, and a variety of IDEs.
Solution:
CoScreen enables pair/mob/team programming like no other solution and we believe it can reduce the cost of context switching by up to 80% [2] so you can focus on what actually matters - reviewing code, troubleshooting bugs, or building major new features.
CoScreen is a desktop app that enables multiple users to share application windows with each other at the same time. You can think of it like a shared desktop where any user can interact with any shared window as if it were their own via remote mouse and keyboard to allow them to collaborate like never before (they can even copy and paste code across windows of different users). In addition to built-in video chat, and remote control, we're also launching a Slack integration so that you can embed CoScreen into your daily workflow. Integrations with VS Code and other IDEs will follow soon.
Our progress since our HN Show post last year:
After CoScreen went to the front page in November 2019 [3], we saw a huge interest in this entirely new way to collaborate and to get things done as a team. We’re incredibly thankful, as it helped us transition from a weekend and late-night project to a full-time undertaking with a stellar, globally distributed team. We've engineered the new app from scratch and we give you more control over what you share than any other tool.
CoScreen uses P2P whenever you and a second participant can connect directly (e.g. when no corporate firewalls or proxies are between the two of you) so none of your window and control data touches our servers. Otherwise, up to a dozen participants can collaborate using our enterprise-grade, HIPAA-compatible video infrastructure with hundreds of servers around the globe that run the awesome open-source framework Jitsi. All video data is encrypted using DTLS-SRTP during transmission and in addition, we’re planning to support end-to-end encryption soon.
With the help of UX experts who originally designed Slack, we've also created a new, minimalistic UI that never gets in your way and have done hundreds of evaluation sessions with testers of our private beta. We're making our new macOS version publicly available today for free [1]. The Windows alpha is already in final internal testing and you can sign up for early access for it and our future Linux and web clients [4].
Can’t wait? See for yourself how CoScreen works [5, 6].
What happens next:
A few hundred early-adopters, and our own internal team have used CoScreen for the last six months.These early insights have been instrumental to our code and design reviews, bug fixing, standups, and feature development since the pandemic hit. Now we want more teams to benefit from CoScreen and are therefore offering CoScreen entirely for free for the next six months. We’ll keep sign-ups open as long as our infrastructure allows. We’re working hard to support other platforms, offer the best performance in terms of latency and quality (it's already much better than Zoom’s), and further reduce CPU and memory usage.
Thanks again to the HN community for helping us to get to this point. Keep telling us what you think via the built-in feedba...
Great question - what the team does at Tuple is great but we have a slightly different take that goes beyond formal pair programming:
1. With CoScreen, more than one user can share their windows with each other at the same time, side by side on the same share desktop - not just one.
2. Up to 12 participants can interact with any shared window using mouse & keyboard across multiple users.
3. You can even copy & paste code between windows shared by different users.
4. We are about to launch our Windows beta so users that aren't on macOS will be able to pair/team program too (and e.g. simultaneously share & interact with macOS AND Windows windows).
I've been using the beta version for the past few months, and it's really been great to see the progress made - Adding thumbnailed webcam feeds of participants was a nice addition and means it can replace Zoom for many of our engineering meetings - Everyone can interact with whatever application(s) are being shared, reducing the "it's your turn to share the screen" or "can you click that button on the top right" friction - Anyone can interact with anything being shared.
Definitely recommend checking it out if you're working on a distributed team.
(no connection to the company, other than being an enthusiastic beta tester :-) )
Coscreen has come a long way. I've been using it for several months and have seen lots of improvements. I like the idea that it's many-to-many versus normal one-to-one pairing. It makes it useful for things like daily team standups in addition normal collaboration.
for me, the main WOW factor is multiple people sharing their windows simultaneously -- such a differentiator. like the post said, this has huge implications for productivity. a new standard in collab.
This seems promising! One thing that confused me initially was that your video made it seem like a second monitor was necessary. Had to go to your FAQ to find out that you can share individual screens.
Thanks for your feedback, we will definitely make it more prominent that single monitor use is definitely a viable use case.
The best experience is definitely with a secondary monitor, that was the original conception of the product, but we have a model of tab-based sharing, and a mechanism to hide windows of specific users, as well as focus the windows of a specific user (click their profile picture), that have made interacting with it on a single monitor a lot more intuitive and nice.
Many of our developers use it exclusively with a single monitor.
Adding to Jason's comment - check out this video that shows a live demo with the single display scenario and individual window sharing: https://www.youtube.com/watch?v=054wVitjVJ0
Hi, eng from the CoScreen team here. Our focus is to allow sharing individual applications not an entire screen. This allows multiple people to concurrently share and have access to all shared apps. In a way it is similar to "Seamless Windows" in Virtualbox - you see and have control over embedded windows from remote machines.

Also do you have a pricing strategy in mind yet for when this moves out of beta? (Sorry if I missed that on the site)
I'd say that Q2 2021 for Linux (Fedora/Ubuntu) is a fair estimate at this point.
We're still figuring things out wrt pricing, but will always offer an affordable option similar to what Slack and Zoom have.
Definitely recommend checking it out if you're working on a distributed team.

Will definitely give this a shot.
