DECLARATIVE AI AGENT ENVIRONMENT MANAGER
カセット — cassette. plug in, swap out, share.
curl -fsSL kasetto.dev/install | shFEATURES
DECLARATIVE
One YAML file replaces every manual setup script you have ever written. Define your skills, MCP servers, and agents once — then forget about them. Your config becomes the single source of truth across every machine and every teammate.
ENTERPRISE & PRIVATE REPOS
Works with GitHub, GitLab, Bitbucket, Codeberg, Gitea, and self-hosted instances out of the box. Onboard new engineers in one command. Everyone gets the exact same environment — zero drift, zero surprises.
MULTI-AGENT
Ship to 21 agents at once — Claude Code, Cursor, Codex, Windsurf, Copilot, and beyond. Stop maintaining separate configs for each tool. One sync, every agent updated, every time.
SKILLS & MCP
Any directory with a SKILL.md is a skill — no registry, no boilerplate. MCP server configs are auto-merged into every supported format. Distribute rules and tools as easily as sharing a repo link.
SPEED
Built in Rust for instant startup. SHA-256 hashing and lock file diffing mean only what changed gets touched. Full sync across all 21 agents finishes in seconds, not coffee breaks.
UNIVERSAL
One static binary — macOS, Linux, Windows. Drop it into CI pipelines with --json output and proper exit codes. Same behavior on a laptop, a Docker container, or a GitHub Actions runner.
