But what if it was different?

Plain helps you
orchestrate your support.

Why We Win

Speed meets power.

We get it — when you’re comparing platforms, everything looks similar.
We’ll make it easy. Here’s why, and when, we win.

We get it — when you’re comparing platforms, everything looks similar. We’ll make it easy. Here’s why, and when, we win.

When you want a workspace made for high-performance customer work.

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, most demanding companies in the world.

When you want complete extensibility and scalability.

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 – so 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.
