About:
OPAM is a package manager for OCaml that handles the installation of compiler switch versions, libraries, and tools. It simplifies dependency management by allowing developers to pin specific package versions and manage multiple sandboxed environments. The tool enables easy sharing of project setups through lock files and repository remotes.
Key Features:
  • Multi-switch compiler management
  • Dependency solving and version pinning
  • Sandboxed environment isolation
  • Lock file generation for reproducible builds
  • Extensible package repository system
Use Cases:
  • Managing multiple OCaml compiler versions on a single system
  • Creating reproducible build environments for OCaml projects
  • Distributing and consuming OCaml libraries and applications
Alternatives:
  • esy – Esy uses npm for package management and focuses on esy-based projects, while OPAM is the native OCaml ecosystem standard
  • opam-local – Local switches provide isolated environments similar to Python virtualenv but integrated with OPAM's dependency solver
