A deterministic, skills-based browser agent that automates web interactions using predefined action recipes for popular sites.
Runtime is a deterministic, skills-based browser agent that automates interactions with websites like Amazon, Gmail, and Google. It uses predefined "skills"—structured action recipes—to perform tasks such as searching products, reading emails, or summarizing content without relying on live DOM manipulation. This solves the problem of slow, unreliable AI browser agents by providing fast, consistent automation directly in your logged-in browser session.
Developers, researchers, and productivity enthusiasts who need to automate repetitive web tasks, conduct research, or integrate browser actions into workflows without vendor lock-in.
Developers choose Runtime for its speed and reliability—it's up to 3x faster than alternatives by using predefined skills instead of runtime DOM manipulation. It runs locally in your own browser session, ensuring privacy and eliminating API dependencies.
Deterministic skills-based browser agent
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Uses hand-crafted skills for sites like Amazon and Gmail, ensuring consistent results without runtime DOM manipulation, as highlighted in the skills method.
Claimed to be 3x faster than alternatives like Comet by avoiding live DOM manipulation, demonstrated in the demo GIF.
Actions are performed in the user's own logged-in browser session, eliminating repeated logins, as noted in the key features.
Runs locally without external API dependencies, providing full control and privacy, as emphasized in the description.
Skills are only predefined for a handful of popular websites like Amazon and Gmail, making automation on most other sites impossible without contribution.
The README admits the skills method is not infinitely scalable, which could hinder automation on numerous or dynamically changing websites.
Requires local installation of Node and Rust, plus configuration of external API keys like Gemini, adding overhead despite claims of no dependencies.
