Curated list of Plan 9 (and sometimes 9p) libraries and software. Generally when referring to "Plan 9" this really means 9front. 9p.io links are accessible over 9p as well. On 9front you can run `9fs 9pio` as a shortcut. Many of the applications listed here are available under the 9front ports tree.
