Vendo

Let your users build their own features on top of your product

About Vendo

Vendo is the customization layer that lets your users build their own features and micro-apps directly on top of your product. Rather than waiting on an ever-growing feature backlog, your users can personalize the product to exactly how they work, create their own automations, and integrate hundreds of external tools, all without your team writing a line of code. Everything runs on your existing API, renders natively in your own theme and components, and executes inside secure sandboxes within your existing security guardrails, so your source code is never touched. Companies can plug Vendo into an agent they already have, or deploy a production-ready agent complete with the ability to take actions in the product, generate UI, and draw on a built-in knowledge base. Vendo is open source and installs with a single command, and we work closely with teams to get it running for their product.
