Launch HN: Vendo (YC S26) – Let users build features on top of your product
GitHub yousefh409
Vendo announced its launch on Hacker News, letting users build new in-product features on top of an existing SaaS by generating React components that call the host product’s API. It uses QuickJS to run the generated code in a sandbox with no access to the DOM, network, or clock. As a result, generated UIs become durable apps users can pin, run on triggers, and share or fork inside the product rather than chat-confined components.
Why it matters
Hi HN, we’re Yousef & Nour, founders of Vendo (https://vendo.run). 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.Demo: https://www.youtube.com/watch?v=VdpHehY64lsWe 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.Here is how it works:- npx vendo init reads the product's API surface, theme, routes, and more. These are used so that the apps Vendo creates (1) look on-brand and native and (2) have the ability to read data and perform
