Our verdict on GHCup

GHCup is an open-source installer and version manager for Haskell development tools. It manages the Glasgow Haskell Compiler (GHC), Cabal, Haskell Language Server, and Stack through command-line and text-based interfaces. Haskell teams can list available tools and versions, install recommended or specific releases, set an active default, and run commands with a selected toolchain. It supports Linux, macOS, Windows, FreeBSD, and WSL2, making it suited to teams working across different development environments.

Its strongest fit is a Haskell workflow that needs explicit control over compiler and tool versions. GHCup supports source compilation for supported tools, while GPG verification protects the integrity of metadata. The documented integrations include Stack and Cabal-install, plus Visual Studio Code for editor workflows and GitHub Actions for continuous integration. Non-interactive installation is particularly relevant for CI runners, where repeatable command-line setup is more useful than an interactive installer.

GHCup keeps its scope focused on installing, selecting, and invoking Haskell tools. It does not provide project pinning or automatic switching, so teams that require per-project toolchain selection or environment changes based on the current directory may need a different approach. Its open-source model suits teams that want a dedicated Haskell toolchain manager without a commercial SaaS layer. Choose GHCup for cross-platform Haskell tool installation, version selection, source builds, and CI setup; choose an alternative when automatic project-based switching is central to the workflow.
