Kosuke

AI-powered live sandbox that lets PMs, designers, and marketing ship small tickets themselves while respecting your codebase.

Kosuke provides a live sandbox environment that enables non-technical team members like PMs, designers, and marketing professionals to handle small development tickets independently. The platform runs existing codebases in secure sandboxes, allowing these stakeholders to ship minor changes such as copy updates, button modifications, tooltip rewrites, and form field additions without requiring engineering resources. Unlike background agents that generate blind code diffs, Kosuke produces tested, mergeable work that respects established code architecture and conventions.
