Three steps to a working agent

From template to deployment in minutes — test locally or in the cloud.

Pick a Template

Choose from curated templates with example prompts and variables — or start from scratch.

Customize & Test

Edit Python code in-browser. Test with WebLLM (local) or connect OpenAI / Anthropic APIs.

Deploy Anywhere

Export a standalone HTML file, embed on your site, or publish to the marketplace.

Why teams choose AgentOp

Everything you need to build, test, and ship AI agents.

Visual & Code Editors

Build with a visual wizard or switch to CodeMirror for full control — both testable in the browser.

Local Model Support

Run quantized models in-browser via WebGPU for on-device privacy — or connect cloud providers.

API Integrations

Connect to OpenAI, Anthropic, or add custom connectors. Encrypted API keys for security.

Privacy First

Control where inference runs. API keys encrypted client-side (AES-256). Nothing stored on our servers.

Export & Embed

Download standalone HTML bundles. Share on the marketplace or embed in any website.

Community

Fork agents, share templates, follow creators. A growing marketplace of ready-to-use agents.

Build agents with Python + any LLM

Write Python tools that run in the browser via Pyodide. Pair with OpenAI, Anthropic, or local WebLLM models — all from a single codebase.
