AgentOp
AgentOp is a web-based platform that allows users to build private AI agents that run entirely in the browser, using open-source large language models (LLMs) accelerated by WebGPU. No installation or server setup is required; the models and runtime operate on-device, ensuring data privacy. Users can write custom Python tools that execute via Pyodide directly in the browser, and test them against local models instantly. The platform provides a code editor, templates for common tasks (such as chat, data analysis, and code review), and an AI agent generator that converts natural language descriptions into functional agents. Finished agents can be exported as a single standalone HTML file, which includes the model loader, Python runtime, and UI, making them fully portable and offline-capable. For tasks requiring more powerful models, AgentOp supports bring-your-own-key connections to cloud-based models from OpenAI and Anthropic, with API keys encrypted client-side to never touch AgentOp servers. The platform is free to use and focuses on openness, with no vendor lock-in, and agents can be shared or embedded easily.

Problem solved
AgentOp solves the challenge of building, testing, and deploying AI agents with local LLMs without complex setup, cloud dependencies, or privacy concerns. It enables developers to create fully self-contained, offline-capable agents that run in a browser tab, eliminating the need for server infrastructure or API keys while maintaining data sovereignty.
