YC-backed Vendo open-sources persistent AI micro-apps for B2B SaaS

Vendo, a YC Summer 2026 startup, open-sourced (Apache-2.0) a layer that lets B2B SaaS users generate custom micro-apps via an AI agent without touching host source code. Unlike chat-scoped AI UIs, these apps persist: users pin, trigger, and fork them across an organization. Generated code runs in a QuickJS sandbox with no DOM, network, or clock access.
