nvm vs ServBay

nvm is a free, MIT-licensed command-line tool for installing and managing Node.js versions. It is designed for installation per user and invocation per shell, and works in POSIX-compliant shells including sh, dash, ksh, zsh, and bash. Users can install specific versions, switch between them, set aliases such as a default, and use LTS aliases and commands to select long-term support versions. A project can specify its Node.js version in an.nvmrc file; documented shell snippets can support automatic switching. During installation, nvm can reinstall global npm packages from another installed Node.js version. With the --offline flag, it can install a version that was previously downloaded or cached without network access. The project documents use in Docker, including an example for CI/CD jobs. On Windows, nvm can work through WSL and may work with Git Bash or Cygwin depending on the environment. Fish shell is not supported, and the project points users to community alternatives. The project states that only the latest nvm version is supported.

ServBay manages local web development environments on macOS and Windows, bringing language runtimes, databases and web servers into one desktop tool. It includes versions of PHP, Python, Node.js, Go, Java,.NET, Ruby and Rust, plus Apache, NGINX and Caddy. Developers can assign runtime versions to projects and switch installed service versions through its management interface. Local services include DNS, mail testing, MinIO object storage and RabbitMQ; built-in PKI supports local HTTPS, and ServBay can manage certificates through ACME. Its MCP server works with Claude Code, Cursor, Codex and other MCP clients, which can manage services and packages, create sites with local DNS and SSL, operate databases, read logs and run diagnostics. The AI Gateway provides one local endpoint for cloud and local model providers, with usage tracking, virtual keys and automatic fallback. ServBay says provider API keys stay encrypted on the user’s machine and are not uploaded. The free plan costs nothing and is limited to five websites and five DNS records. Pro starts at $9.90 a month; a 7-day trial is listed.
