Unlock Web Automation with Nanobrowser: Your Free AI-Powered Chrome Extension

Are you looking to streamline repetitive online tasks, perform in-depth web research, or automate complex workflows without breaking the bank? Meet Nanobrowser, an innovative open-source Chrome extension that brings powerful AI-driven web automation right to your browser.

Positioned as a compelling free alternative to expensive tools like OpenAI Operator, Nanobrowser empowers users with a multi-agent system and the flexibility to integrate their own Large Language Model (LLM) API keys. This means you pay only for your LLM usage, with no subscription fees or hidden costs, making advanced web automation accessible to everyone.

Why Nanobrowser Stands Out:

Nanobrowser isn't just another automation tool; it’s built with user control and privacy at its core. Here's what makes it a game-changer:

• 100% Free: Say goodbye to monthly subscriptions. Nanobrowser is completely free to install and use, leveraging your existing LLM API keys.
• Privacy-Focused: All operations run locally within your browser. Your data and credentials remain on your machine, never shared with third-party cloud services.
• Flexible LLM Options: Connect to a wide array of LLM providers including OpenAI, Anthropic, Gemini, Ollama, Groq, Cerebras, Llama, and other OpenAI-compatible services. Assign different models to different agents for optimized performance and cost efficiency.
• Fully Open Source: Experience complete transparency. The codebase is open for inspection, ensuring no black boxes or hidden processes.
• Multi-Agent System: Specialized AI agents collaborate to tackle complex web workflows, adapting and self-correcting as needed.
• Interactive Side Panel: A user-friendly chat interface provides real-time status updates and allows for contextual follow-up questions.

Key Features for Enhanced Productivity:

Nanobrowser is packed with features designed to make web automation intuitive and powerful:

• Task Automation: Seamlessly automate repetitive tasks across various websites.
• Conversation History: Easily manage and review your AI agent interactions.
• Browser Support: Officially supported on Chrome and Edge, ensuring a smooth and reliable experience.

Getting Started with Nanobrowser:

Installation is straightforward, whether you prefer the stable version from the Chrome Web Store or the latest updates via manual installation:

Chrome Web Store (Stable Version): 1. Visit the Nanobrowser Chrome Web Store page. 2. Click "Add to Chrome" and confirm the installation.

Manually Install (Latest Version): 1. Download the latest nanobrowser.zip from the official GitHub release page. 2. Unzip the file. 3. Navigate to chrome://extensions/ in your browser, enable "Developer mode," click "Load unpacked," and select the unzipped Nanobrowser folder.

Once installed, click the Nanobrowser icon in your toolbar, open the settings, and add your preferred LLM API keys. You can then choose which models the 'Navigator' and 'Planner' agents will use.

Optimize with Model Configurations:

Nanobrowser allows you to configure different LLM models for various agents to balance performance and cost. For example:

• Better Performance: Pair Claude Sonnet 4 for the Planner (reasoning) with Claude Haiku 3.5 for the Navigator (web navigation).
• Cost-Effective: Utilize Claude Haiku or GPT-4o for the Planner and Gemini 2.5 Flash or GPT-4o-mini for the Navigator.
• Local Models: For ultimate privacy and zero API costs, run models locally using Ollama or other custom OpenAI-compatible providers. Popular choices include Qwen3-30B, Falcon3 10B, and Mistral Small 24B.

See it in Action:

Imagine accomplishing tasks like these with a single command:

• "Go to TechCrunch and extract top 10 headlines from the last 24 hours."
• "Look for the trending Python repositories on GitHub with the most stars."
• "Find a portable Bluetooth speaker on Amazon, water-resistant, under $50, with a minimum battery life of 10 hours."

Nanobrowser makes these complex instructions simple to execute.
