Vendo (YC S26) launches open-source tool for persistent, AI-generated micro-apps inside B2B SaaS

Vendo, a YC Summer 2026 startup, publicly launched an open-source (Apache-2.0) layer letting B2B SaaS end users generate custom micro-apps via an AI agent — without modifying host source code. Unlike chat-scoped AI UIs, Vendo's apps persist: users pin, trigger, and fork them across an organization. Generated code runs in a QuickJS VM sandbox with no DOM, network, or clock access.
