Devbox vs FlyEnv

Devbox is an open-source command-line tool for creating isolated development shells from declared package lists. A project’s devbox.json can define packages, scripts, services, and environment configuration, drawing on a searchable Nix-powered catalog with over 400,000 versions of 80,000 packages. One definition can produce a local shell, a VS Code devcontainer, a Dockerfile, or a remote cloud development environment. Devbox can orchestrate project services with process-compose without Docker; Docker is needed only for container creation. The GitHub Action installs Devbox and can cache the Nix store in workflows, and documented integrations include direnv and a Visual Studio Code extension. Installation guidance lists Linux, macOS, and Windows through WSL2, and Devbox requires the Nix Package Manager. Jetify offers cloud and secrets services alongside the tool.

FlyEnv is a desktop application for managing local development environments on Linux, macOS and Windows. It supports container-free local workflows and offline operation. Developers can install and switch among language runtimes including PHP, Node.js, Python, Java, Go, Ruby and Rust, then scope runtime settings to a project. Those settings are stored in a.flyenv file and control the toolchain used by terminals, editors and run commands. The local-site module includes settings for custom domains, document roots, server ports, PHP binding, rewrite rules, reverse proxies and HTTPS. Listed database integrations include MySQL, PostgreSQL, MariaDB, MongoDB, Qdrant, ClickHouse and Neo4j; its AI integrations include tools and services such as Codex, Ollama and Claude Code. The free plan includes 3 local sites and 3 custom projects per runtime. The Pro License costs 10.00 USD once and includes unlimited local sites and custom projects, with one active device at a time. FlyEnv is intended for personal or business development use.
