Launch HN: Vendo (YC S26) – Let users build features on top of your product
Summary
Vendo offers an open-source layer that lets SaaS vendors expose embedded agents to automate work and let customers build features on top of their product. The platform reads your API into tools the agent can use, generates brand-native UI in a sandbox, and enforces policy and approvals at a single choke point. It ships with modular blocks and MCP integration for external clients, enabling live views, UI remix, and cross-tool automation.
