Your users describe a feature. Rough builds it.
Inside your product, users open the builder and say what they need. Rough writes a Feature against the contract. It can only do what you allow it to.
Build Rough lets your team, and even your customers, create bespoke features inside your product.
"I want graphs" 
"Show me customers" 
"Show cool stats" Engineering decide where features can be built, and how powerful they can be. Defining this contract is the whole implementation. Rough handles the hosting, token management and feature state.
Embed Inside your product, users open the builder and say what they need. Rough writes a Feature against the contract. It can only do what you allow it to.
Build Rough tracks who built each Feature, who uses it, and what it touches. When the same one keeps showing up, you can take it into the main product.
Manage Every feature your users build lives in its own little box. The box is the boundary. It can only see and do what you said it could.
Features run in their own isolated runtime. They can't reach into your product or interfere with other features. If one breaks, the rest keep working.
Your engineers decide what each feature can read and what actions it can call. If you didn't expose deleteUser, no feature can call deleteUser. The contract is the only door.
Features inherit the user's session. Even when the contract allows an action, the user's own permissions still apply. A feature can never do something the user couldn't have done themselves.
Features run inside your product's own page, using the actions you exposed and the session your user already has. We don't call your MCP server. We don't go around the client to hit your API.
Engineering You decide what data is exposed and what Features can call against it. The runtime enforces that contract. Stay focused on the core of your product.
Product Edge cases stop derailing the quarter. Turn bespoke feature requests into delighted customers and see what patterns emerge.
Sales Build the missing feature into the demo, in front of the prospect, before they sign. You don't have to promise anything for next quarter.
CS When a customer asks for a tweak, build it for them on the call. Or hand them the builder and let them do it. No engineering required.
Customers Let your customers solve their own problems before they become pain.
