STABLE ECOSYSTEM
Focus on Your Code, and Opam Takes Care of Distributing It.
Our users have the highest standards for the OCaml ecosystem to run
mission-critical applications across a variety of operating systems, and they expect that a package that
compiles today will still work a decade from now.
Continuous Integration
Before any package update, we run sandboxed matrix builds for
boundaries of the dependencies and for each of the dependent packages. A package publication will
never break the rest of the ecosystem.
State of the Art
Opam supports publishing multiple versions of packages
simultaneously to specify the version constraints, so only compatible revisions are
chosen for a build. It comes with a performant constraint solver, a flexible CLI, a well-specified
metadata format, and an easy access to the package manager logic via OCaml libraries.
Stability
The Opam project and package repository is maintained by a team of
developers who ensure that everything is not only running smoothly, but also curated to maintain a high
degree of metadata quality. This makes it one of the most stable package repositories available
today.
