## What it is
The core OCaml compiler system, including bytecode and native-code compilers, a runtime system with generational garbage collection, and the base standard libraries. It is the reference implementation of the OCaml functional programming language, distributed via opam and actively maintained with regular releases.

## Use cases
- compile ocaml programs to fast native executables
- learn a statically typed functional programming language
- build reliable mission-critical software with strong type safety
- compile ocaml to portable bytecode
- set up an ocaml development environment with opam
- write high-performance systems code with garbage collection

## When to choose
- you want an industrial-strength functional language with type inference and pattern matching
- you need both fast native compilation and portable bytecode output
- you are building complex, maintainable codebases where compile-time safety matters
- you want a mature language with long-term support branches

## When to avoid
- you need a language with a huge general-purpose ecosystem of libraries
- your team has no functional programming experience and needs quick onboarding
- you require C-level manual memory control
- you need first-class mobile or web runtime support out of the box

## Facets
- artifact type: cli-tool
- maturity: stable
- function: compiler, interpreter, programming-language, developer-tools
- domain: programming-languages, compilers, developer-tools, cross-platform
- platform: windows, bsd, cross-platform, cli
- tags: ocaml, functional-programming, type-inference, garbage-collection, bytecode, native-code-compiler, standard-library, linux, macos
