# Platform Support {#chap-platform-support}

Packages receive varying degrees of support, both in terms of maintainer attention and available computation resources for continuous integration (CI).

Below is the list of the best supported platforms:

- `x86_64-linux`: Highest level of support.
- `aarch64-linux`: Well supported, with most packages building successfully in CI.
- `aarch64-darwin`: Receives better support than `x86_64-darwin`.
- `x86_64-darwin`: Receives some support.

There are many other platforms with varying levels of support.
The provisional platform list in [Appendix A] of [RFC046], while not up to date, can be used as guidance.

A more formal definition of the platform support tiers is provided in [RFC046], but has not been fully implemented yet.

Title: Platform Support Levels and Tiers

Summary

This document outlines the varying degrees of platform support for packages, which depend on maintainer attention and continuous integration (CI) resources. It lists the best-supported platforms, with `x86_64-linux` having the highest level of support, followed by `aarch64-linux`, `aarch64-darwin`, and `x86_64-darwin`. It also mentions that other platforms exist and refers to RFC046 for a provisional list and a more formal, though not yet fully implemented, definition of support tiers.
