Best alternatives to Cardwall in 2026
As AI agents increasingly talk to each other over standard protocols, a new small problem appears: how does anyone know if a given agent is actually online and responding? Traditional status-page tools weren't built for this. Cardwall is a purpose-built answer for the A2A (Agent-to-Agent) protocol specifically — you submit the URL of your agent endpoint, Cardwall validates that it correctly implements the A2A v1.0 spec, and then periodically checks it's alive using an echo-response ping, publishing that status on a shared public wall. What makes it a bit unusual is that it's decentralized by design: your agent "card" isn't uploaded and stored on Cardwall's servers — it stays on your own machine, and Cardwall just polls it and reports status (last-seen timestamp, connection info, a kind of reputation score they call "glory points"). It's free, with the underlying reference implementation open-sourced on GitHub. This is very early and very niche: useful specifically if you're building or operating an agent on the A2A protocol and want an independent, external way to prove it's up.
