Apps are interactive, AI-generated web applications that live inside OpenSwarm. Instead of paying for software or spending weeks building UIs, you describe what you want and an agent writes it for you — a live, runnable app appears in seconds.
“In the past, we used to have to pay for expensive applications. Now, you can prompt them into existence.”

​
What is an App?

An App in OpenSwarm is a self-contained, reusable interface that:
  • Runs directly inside the OpenSwarm dashboard
  • Runs a Python backend for data processing, API calls, or computation
Apps are built from files — at minimum an index.html for the frontend, and optionally a backend.py for server-side logic.

​
What can Apps do?

Apps are full web applications. Anything that runs in a browser can be an App:
  • Data dashboards — charts, tables, live stats
  • Calculators and tools — mortgage calculators, unit converters, ROI estimators
  • Form UIs — contact forms, intake flows, data entry interfaces
  • Visualizations — maps, graphs, timelines, org charts
  • Utilities — markdown renderers, JSON formatters, color pickers
  • Mini-apps — Pomodoro timers, kanban boards, invoice generators
  • Games — anything playable in a browser
The frontend can use any JavaScript library that loads from a CDN (React, Chart.js, Tailwind, D3, etc.). No bundler required.

​
The Apps library

All your Apps live on the Apps page (/apps). Each App is shown as a card with:
  • A thumbnail (auto-captured from the last preview, or a default icon)
  • The App’s name and description
  • Quick-action buttons to run, edit, or delete
From the library you can launch any App instantly, without going back into the editor.

​
How Apps relate to agents

An app that has already been created can be used by an agent the same way a human uses the app. You can think of this like the Browser use agentic capabilities, but for a custom App. You can build Apps manually in the editor, or ask any agent in any mode to generate App code for you directly from a workspace.
