Build Fastor with Castor
The next generation AI IDE that unifies requirements, design diagrams, and code generation with round-trip synchronization.
Everything you need to make better software
Castor IDE is a next-generation IDE built on top of Theia IDE. Its goal is to shift the developer’s focus from just writing code to practising real software engineering. While traditional IDEs treat code as the sole artifact, Castor, through the use of complex AI agents, unifies requirements, diagrams, architecture, and implementation into a single cohesive workspace which elevates the practice of software engineering.
