Magnitude is an open-source, vision-first browser agent designed to interact with web interfaces much like a human would. It aims to be accurate, reliable, and fully customizable, enabling real production usage for browser automation.

Key Features:

• Full vision: The agent sees and interacts with the screen like a human, handling complex applications.
• Ease of use: It offers a natural language interface for easy learning and automation syntax.
• Self-healing: Automations are designed not to break when page changes occur, significantly reducing maintenance.
• Repeatable: Actions taken during automation are cached for deterministic execution.
• AI-native architecture: Built from the ground up for reliable, fast, and deterministic browser automation.
• Playwright compatibility: Provides access to Playwright page and context objects for flexibility.

Use Cases:

• General purpose automation.
• Test automation within existing projects.
• Example: Extracting recent issues from GitHub and creating tasks for them in a task manager.

Benefits:

• Accurate and reliable browser interaction.
• Fully customizable for production usage.
• True generalization independent of DOM structure due to visually grounded LLM specifying pixel coordinates.
• Future-proof architecture for desktop apps and VMs.
• Flexible abstraction levels (granular actions vs. flows).
• Custom actions and prompts at agent and action level.
• Deterministic runs via native caching (in progress).
• No self-hosting or GPU required when using Claude from Anthropic.
• Fast and reliable execution.
