Hi HN, we're Yousef & Nour, founders of Vendo. Vendo lets users create new features inside the software they already use. A user describes the dashboard, workflow, or small app they need, and Vendo builds it on top of the product's existing data, API, and interface.

We built Vendo because every SaaS eventually faces the same problem: every customer needs something slightly different. One wants a new report and another needs a workflow that only makes sense for their team. These requests either sit on the roadmap, become one-off engineering work, or force the customer into spreadsheets and external tools. We wanted the user to be able to create the missing feature themselves, without leaving the product.

There's a lot of generative UI right now: streaming developer-written components into a chat (Vercel AI SDK, CopilotKit, Thesys), or rendering your app inside someone else's assistant (OpenAI Apps SDK, MCP Apps). We differ on two things. Vendo lives in your product and acts through your API as the signed-in user, so what it makes is durable: real apps users keep, pin, and run on triggers while they're away, and not components that are merely confined to a chat.

Vendo is completely open-source (Apache-2.0) and can be self-hosted, so feel free to check out all the source code here: [https://github.com/runvendo/vendo](https://github.com/runvendo/vendo). Would love you to try it out and give us your feedback: [https://docs.vendo.run/](https://docs.vendo.run/).
