FVM vs ServBay

FVM manages Flutter SDK versions by project, allowing teams to keep builds consistent while using different versions across projects. A project’s `.fvmrc` file records its selected Flutter version and can include project-specific settings and flavors. FVM switches among installed SDKs without downloading them again. It can identify unreferenced versions, preview cleanup candidates, and remove unused SDKs with `fvm cleanup`. The documentation describes commands suitable for CI/CD automation and support for custom Flutter repositories. FVM provides packages for macOS, Linux, and Windows, with architecture availability varying by system. Installation options include a shell script, Homebrew, Chocolatey, Pub, and standalone packages. FVM detects VS Code and updates `.vscode/settings.json` for the Dart Code extension to use the project’s managed SDK. Android Studio and IntelliJ settings must be configured separately to point to the FVM SDK path. JSON API commands expose installed SDKs, releases, cleanup data, environment context, and project configuration. FVM stores known project roots in a machine-local file and says it does not scan disks for projects. The project is licensed under MIT.

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.
