Design aistartupbackendfrontend Vendo
Vendo is an open-source customization layer that lets users build their own micro-apps directly within your product interface.
What: Backed by Y Combinator and Founders, Inc., Vendo provides an agentic interface that connects to your repo, learns your components and API, and lets users create custom automations or dashboard views. It works as an overlay or sidebar in existing apps like Cal.com or Dub.co.
Why it matters: This represents a shift toward 'user-defined software,' where applications transition from static tools into platforms that end-users can program via natural language.
Deep dive
  • Vendo scans existing Next.js routes, themes, and APIs to generate a safe, sandboxed execution environment.
  • Users can ask for custom micro-apps that run with the user's existing permissions.
  • It supports embedding across your own UI, or within Claude and ChatGPT sessions.
  • The free tier includes $5/month in usage; Pro tiers allow for team-based governance and deployments.
Decoder
  • Agentic interface: A UI layer powered by AI agents that can perform actions, manage state, and build functional software components based on user intent.

Your product, shaped to every customer.

An open-source customization layer. Your users build their own features and micro-apps, right on top of your product.

The interface that builds itself.

Your customers describe what they need, and your product assembles it live. Not throwaway generated UI: real micro-apps with actions, automations, and state, theirs to keep. No ticket, no roadmap, no waiting.

“What did I spend when I should’ve been asleep?”

Views on demand

Any slice of your product, composed into a working dashboard.

Standing automations

“Every Monday at 7” becomes software that runs itself.

Their tools, wired in

Gmail, Slack, GitHub, connected as themselves.

Real micro-apps

UI, data, and logic assembled live. The interface builds itself.

It learns your product. It never exceeds it.

One command reads your repo and learns everything: your components and colors, your API as callable tools, your permission rules. What it builds wears your brand, runs sandboxed as the signed-in customer, and never steps outside permissions they already have.

npx vendo init

One app. Everywhere your customer already is.

In your product

Every surface you choose: an overlay, a chat sidebar, a full panel, or remixed into your own components.

In Claude & ChatGPT

Their AI opens it too. Same app, still wearing your brand.

On a schedule

Works while they sleep with exactly the permissions they gave it.

Free where it matters.

The single-player agent is complete and open source, with the LLM judge and metering included. Cloud is everything multiplayer.
