Pricing: Open-source platform with no upfront costs; potential costs are related to API usage (~$0.02 per build) and cloud infrastructure if applicable.
Run an army of Claude Code, Codex, etc. on your machine
Superset is an innovative IDE designed to supercharge developer productivity by enabling the seamless integration and management of multiple AI coding agents like Claude, Codex, and others. It allows developers to run several agents simultaneously without the typical overhead of context switching, each within its own sandbox environment to prevent interference. With its centralized dashboard, users can monitor all ongoing tasks, receive notifications for updates, and review changes efficiently using an integrated diff viewer. This setup significantly accelerates workflows, reduces frustration, and helps teams ship features faster. Ideal for AI developers, machine learning engineers, and advanced programmers, Superset transforms the coding process into a more organized, efficient, and collaborative experience, making complex multi-agent projects manageable and scalable.
