Local vs Nix

Local is a free desktop application for developing WordPress sites on Windows, macOS, and Linux. It installs WordPress with one click and includes SSL for each site. Development features include root SSH access, WP-CLI, and hot-swappable PHP environments. Local provides native PHP, MySQL, NGINX, and Apache services, with switching between NGINX and Apache. Sites can be imported or exported with their files, databases, and configuration files. Local Connect pushes and pulls sites to Flywheel and WP Engine; Connect is free, while hosting costs depend on the selected hosting plan. Cloud Backups connects Dropbox or Google Drive for project files, directories, and databases, but backups must be started through its interface. Live Links creates secure persistent URLs for client and coworker review. Image Optimizer compresses local image files offline. An HTTP/HTTPS tunnel exposes a site to other devices and supports testing Stripe WebHooks, PayPal IPN, and REST APIs. Downloads include macOS Intel, macOS Apple Silicon, Windows, Debian-based Linux, and RPM-based Linux. Support resources include forums, documentation, and release notes. WP Engine says it collects service telemetry.

Nix is a free package management and system configuration tool for creating reproducible, declarative systems. It builds packages in isolation to avoid undeclared dependencies and help keep builds consistent across machines. Users can define and share development and build environments across projects and languages, install software from URLs or source code, and use virtual machines for integration testing. Nix supports dependency resolution, lockfiles, workspaces and offline installation; its package formats include Nix expressions, derivations and flakes. The Nix Packages collection offers over 140,000 packages. The wider ecosystem supports remote builds and deployments, binary caches, cross compilation, atomic upgrades and rollbacks to earlier package versions. Nix runs on Linux and macOS, and on Windows through WSL2; multi-user Windows installation requires WSL systemd support. Documentation includes guides for GitHub Actions, Docker images, Terraform deployment, SSH provisioning and distributed builds. Nix is aimed at people familiar with command-line interfaces and plain-text editors, including developers, test engineers, DevOps engineers, system administrators, data scientists, students and open-source enthusiasts. It has no paid plan listed.
