The projects the community has voted for, ranked by GitHub stars.
Stars are an imperfect but honest signal: developers star what they use, admire, or intend to come back to. This is the directory ranked by that signal — the projects that have earned the most attention in the x402 and AI-agent-payments ecosystem.
Use it as a map of where the community’s energy is. For a quality-filtered view (traction plus active maintenance), see the production-ready collection.
