Floodtide vs Topgrade

Topgrade is a free command-line tool that detects tools in use and runs the commands needed to update them. Run it with the `topgrade` command. The project provides self-updating binaries, source installation, and package-manager options; release binaries cover macOS, Windows, Linux, and FreeBSD. Its example configuration includes Arch package managers, DNF, Nix, Homebrew, Flatpak, and Winget. Topgrade can pull or fetch configured Git repositories, and custom commands can run before, during, or after its built-in commands. It can use SSH to run Topgrade on configured remote hosts before acting locally. On first run, it creates a configuration file if one is missing and also loads and merges files from `topgrade.d`. The project describes itself as a fork of r-darwish's Topgrade that aims to keep the tool maintained. Its example configuration advises against running it as root on Unix, since it invokes sudo or an equivalent where needed. Only the latest version is supported, and fixes are not backported.
