agent-browser

Asteroid is an AI-driven browser-automation platform that lets both non-technical users and engineers build, deploy, monitor, and refine complex web workflows without writing traditional code. Its core is a graph-based agent builder where you describe desired tasks in natural language and configure repeatable logic with variables and structured outputs. Behind the scenes, Asteroid combines encrypted credential management, selector-based guardrails powered by Playwright, and live browser control to navigate pages, interact with UI elements, and call external APIs as needed. You can instantly deploy agents via a RESTful API, embed them into existing systems, or iterate in the platform’s console with real-time supervision, debugging tools, and human-in-the-loop checkpoints. Use cases range from multi-step data retrieval (insurance quotes, grant applications) and intelligent data entry into legacy systems (patient records, supplier portals) to automated reporting.

Lightpanda is an open source headless web browser designed specifically for AI systems and large-scale web automation workloads. Unlike traditional browsers such as Chrome or Firefox that are built primarily for human interaction and graphical rendering, Lightpanda is engineered from the ground up for machines and automated processes. It runs without a graphical interface and focuses only on the components required for programmatic web interaction, such as HTML parsing, DOM tree construction, and JavaScript execution. By eliminating visual rendering tasks like layout calculations, image loading, and pixel painting, the system dramatically reduces resource usage and improves performance for automation tasks. Lightpanda was built from scratch using the Zig programming language rather than modifying an existing browser engine, allowing it to be optimized for speed, reliability, and minimal memory consumption.
