When you want a workspace for high-performance customer work
Read about performance
Plain is beautifully crafted, instant, and intuitive. It’s designed for work, not to feel like work. Our UI has been stress-tested, forged, and iterated on by and with some of the fastest-growing, and most demanding companies in the world. They love it, and we think you will too.
When you want complete extensibility and scalability
Learn about our API
Plain is the only API-first support platform in existence (as far as we know). This means that our app is built on the same API we make available to you. Anything Plain can do, you can do programmatically. There are no limits. We think support is infrastructure and you should be able to build on it.
Start fast. Scale fearlessly. Plain isn’t just faster, it’s built to last.
