Power Codex — Downloads

Codex that finishes features — multi-account power, recovery, zero babysitting.

Added to the Power Agents family by popular demand Power Codex is the Codex host of the Power Claude engine. Downloads and store counts on this page are Power Codex listings only — they are not Power Claude install totals.

New Power Codex mirrors start at zero — they do not inherit Power Claude store totals.

Download Power Codex as a .vsix from this site. VS Code Marketplace, npm, and GitHub Releases are Power Claude mirrors today. Added to the Power Agents family by popular demand and ships its own install artifact here.
