Show HN: Multi-display screen sharing with CoScreen

Good to be back on HN with all-new CoScreen, a little more than 3 years after it launched over here!

With CoScreen 5.0, you can now share your windows from multiple displays at the same time, a long standing request by our most avid users and impossible in other apps. It also has a lightning-fast, Rust-based window compositing, scaling, and streaming engine now.

CoScreen was always meant to be different so that you and your team can share your screens simultaneously and multi-directionally, and to be able to control what is being shared. We saw it as a natural extension and closely coupled with your OS — instant, fast, and seamless. A better way to pair program, debug tough incidents, or jam on great ideas by sharing multi-modal information like code, commands, graphs, or logs.

All that made a lot of sense conceptually but to be frank, it was hard to get it right. Now a part of Datadog and with major parts of our app rewritten in Rust, we feel we’re closer than ever.

Here’s what pair programmers liked about CoScreen, so we made it even better: - High definition code sharing: Windows are video-streamed in real-time at their native resolution whenever possible. You never have to search for your IDE anymore or be anxious to share the wrong window. - Multi-directional collaboration: You can share, while Alice shares, while Bob shares. Side-by-side, across multiple displays. With built-in crisp audio and video chat. - 60FPS+ super smooth mouse pointers. Type, click, and draw on any shared window as if it was your own.

What some of you did NOT like, so we fixed it in CoScreen V5: - CPU utilization and latency have been reduced drastically as various parts of our desktop client are now implemented in Rust, building on crates such as cxx, rust-skia, iced, as well as Neon for our native remote control plugins. - No more accidental clicking into remote windows through the new remote window toggles. - You’re no longer bound by your displays, can share windows from multiple of them at the same time and even move them across displays while sharing without stopping. - You’ll also soon be able to join meetings from your browser from any platform.

CoScreen runs on macOS (x64 and Apple Silicon), Windows, soon also on the web and is currently free. We’re planning to charge for larger teams and enterprise features in the future. Hopefully - finally - we’ll also have a Linux version one day. Tell us if you need it urgently and if you have any other requirements!

Launch HN: Inri (YC W23) – Wealthfront for Investing in India

Hello everyone, I’m Nishad, cofounder at Inri (https://www.goinri.com/), an investment platform for Indian expats to diversify capital in India, without any taxation or repatriation hassles. Super excited to be launching on HN, the platform that I personally nerd on and has helped me discover some of my favorite products early.

My cofounder Hemant (@hemantgangolia) has been living in the US since 6 years and has tried multiple times to invest in India. He couldn't go ahead with the process because bank account opening was a challenge and the process after that wasn't clear. There is complexity around taxation, moving money back and a general lack of clarity on where to invest.

Even though there are currently over 30 million Indian expats globally, there are no digital, full-service solutions offered for them specifically. US solutions focus only on US investments and Indian solutions focus only on Indian customers—this makes the India <> US belt underserved. Indian banks with overseas branches offer these services, but investors don’t trust these banks because of conflict of interest. There are other small players in the market but they expect customers to do their own service, which is not what customers want, based on our learnings.

We found a lot of other Indian expats in the same situation as us - wanting to invest in India for financial and emotional reasons, but unable to do so easily or consistently. We wished a simple product existed to solve for this online. We couldn’t find one, so we built it.

Inri is like Wealthfront for your India investments. It is a web platform that offers curated mutual fund portfolios and solves for all tax compliance and repatriation needs online. We have curated the funds based on performance, history and compliance based on your resident country, and funds are selected based on your risk preference, similarly to Wealthfront. We facilitate investments through central platforms like National Stock Exchange and show the holdings via a dashboard on the platform once the investments are done. Additionally, we do this while making tax compliance and repatriation easy.

Just log in to the platform, upload your documents, approve the emails with details confirmation and you’re sorted. Currently, only people with a PAN card (Indian financial identity document) can invest.

Our early customers are all people who have tried doing this before, but gave up because of all the hassle. The fact that they could get invested in just 2 days vs weeks for traditional alternatives was unheard of to them.

We know this is a bit of a niche product for HN but we also know that there are quite a few Indian expats like us here, who could make use of it—and we hope it makes interesting enough reading for everybody else. We would love to get your feedback! Thank you!
