Launch HN: Vendo (YC S26) – Let users build features on top of your product

Vendo enables SaaS users to build custom dashboards, workflows, and small apps directly within the host product by describing the desired feature, after which Vendo generates a sandboxed React component compiled with QuickJS and rendered via the product’s API. The system reads the product’s API surface and theme, ensures type-checked, API-driven execution, and supports durable, shareable apps for reporting, automations, and bespoke business logic.
