lyno is described as 'Lyno enables remote teams to collaborate as if they were on site. By extending established tools like Slack or Microsoft Teams with an intuitive way of synchronous collaboration we create an exciting virtual presence' and is an app in the Office & Productivity category. There are four alternatives to lyno for a variety of platforms, including Mac, Windows, Linux, Online / Web-based and SaaS. The best alternative is Sococo. It's not free, so if you're looking for a free alternative, you could try Pragli or Tandem - Virtual Office.
We created Pragli (pragli.com) as an online office for distributed teams. Our product enables remote workers to frictionlessly dive into impromptu conversations with audio channels and direct conversations, similar to a walkie talkie.
