AgentOp is a browser-based platform for building, testing, and exporting private AI agents that run open-source LLMs entirely on your device — no servers, no install, no data leaving your tab.
What is AgentOp?
AgentOp is a browser-based platform that lets you build private AI agents using local open-source language models such as Llama 3.2, Qwen, Gemma, Phi, and DeepSeek — all running completely on your device via WebGPU (with CPU fallback via WebAssembly). You write agent logic as Python tools executed in-browser by Pyodide, test them instantly against a local model, and export the entire agent as a single standalone HTML file that includes the model loader, Python runtime, UI, and encryption. This file runs offline on any modern browser without any installation or account. AgentOp is free to start — no credit card required.
Key Features
- On-device inference — Models are downloaded once, cached in your browser, and inference runs on your CPU/GPU via WebGPU or WebAssembly. Your prompts and data never leave the page when using local models.
- Python tool support — Define tool schemas and handlers in Python using Pyodide 0.29, with grammar-constrained (GBNF) function calling that works identically across local and cloud models.
- Single-file export — The agent is packaged as one standalone HTML file that includes everything needed to run offline without internet, install, or account. The file never expires and can be emailed, embedded, or dropped on a USB stick.
- Cloud model integration — Optionally connect your own OpenAI or Anthropic API key for GPT-4 or Claude. Keys are encrypted client-side with AES-256 and never sent to AgentOp servers. You can mix local and cloud calls: cheap drafts locally, hard calls in the cloud.
- AI agent generator — Describe your agent in plain English and AI writes the complete agent (HTML, Python tools, prompts, UI) in seconds. Your API key stays in your browser and makes only one call to the LLM — AgentOp never sees the key.
- Marketplace of agents and templates — Browse public agents and templates to fork and customize, or publish your own agent to the marketplace.
