b is a modern binary manager and environment file syncer that simplifies how developers install, manage, and version their command-line tools and configuration files. With project-based configuration and automatic PATH management, b ensures your development environment is consistent and reproducible.

Why b?

Managing command-line tools and shared configuration across different projects and environments is challenging:

• Version Conflicts: Different projects need different tool versions
• Environment Setup: Complex PATH management and installation procedures
• Team Consistency: Ensuring everyone uses the same tool versions and configs
• CI/CD Integration: Reproducible builds with exact tool versions
• Config Drift: Upstream configuration changes that need to be synced

b solves these problems by providing:

• Project-based Configuration - Each project defines its required tools and env files
• Automatic PATH Management - Tools are available when you need them
• Version Control - Lock specific versions for reproducible builds via b.lock
• Team Collaboration - Share tool and config requirements via b.yaml
• CI/CD Ready - Simple integration with build pipelines
• Env File Sync - Sync configuration files from upstream git repos with three-way merge

Get Started

Install b and start managing your development tools in minutes.

Quick Example

# Initialize a new project
