Capafy is a marketplace for agent skills rather than for agents themselves. A skill is a packaged capability an agent can load, and the distinction matters because the useful unit of reuse in agentic work is not a whole assistant but a specific competence someone has already got working reliably.
It targets the runtimes developers actually use, listing skills for Claude Code, Codex and similar environments, and lets skills be run online as well as downloaded. That means a skill can be evaluated before it is wired into a workflow, which is the practical difference between a marketplace and a package registry.
There is a seller side, so people who build a good skill can earn from it. As with any open marketplace the quality range is wide, so judge the specific skill you intend to use rather than the platform average, and check when it was last updated since agent runtimes change quickly.
