PickAPlugin vs other plugin directories

We'd rather you find the right plugin than stay on our site. Here's where else to look, and when each one is the better pick. Counts are what each site says about itself as of Oct 27, 2026.

PickAPlugin (us)

346 plugins, hand-sorted into 12 plain-English categories, with pages by language and license, "best of" pages like best review and testing plugins, and free browser tools. There's no sign-up. We're smaller than some of the lists below on purpose: we leave out repos that are dead or only half work.

Pick it if: you want a quick, readable shortlist with the install command right there.

Questions people ask

Which Codex plugin directory is the biggest?

By their own counts, CodexStacks and Codex Harness list the most (roughly 900–1,000+ as of Oct 27, 2026). Bigger isn't always better, so check what filter each uses.

Can I use more than one?

Sure. They're all free to browse, and the install command is the same wherever you find a plugin.
