Host your Farcaster channel
Plaza turns a small Hypersnap Lite node into a community square: QR login, temporary signers, local origin memory, global Farcaster distribution.
global identity
Run a plaza
- Install Hypersnap Lite. It creates
~/.hypersnap-lite, starts the local node, and opens the command center. - Scan once as the host account. This is the Farcaster identity that runs the channel.
- Open the guest page. People scan a QR, get a temporary signer, and post through this node.
- Every message still goes to Farcaster. The plaza keeps a local origin trail of what happened here.
After it runs, open the localhost command center it prints. That is where the host account scans once, posts, and creates guest sessions.
When you want other people to join from their phones, use the command center's public guest link flow. It opens a temporary internet URL for your local guest page so people can scan, connect their Farcaster account, and post through this plaza.
Then send this agent prompt to the coding agent working on the community. The agent can use it as context to evolve the plaza in whatever direction the community needs: event wall, local archive, channel client, Neynar-powered channel context, moderation tools, or something stranger.
What this is
A plaza is a self-hosted Farcaster channel surface. The host runs the node. Visitors bring their own Farcaster identity. Posting happens through temporary signer sessions.
No full-state sync. No app-store gate. No platform permission. Just a local write node, QR auth, and signed messages leaving your machine.
Inspect the code and the reasoning behind the Lite architecture.
What communities can build
Put one QR at the door. People scan, post, and leave with their identity intact.
A local square for notices, memories, questions, and coordination.
Capture the conversation from the place where it happened.
Let a club, DAO, venue, or workshop host its own posting surface.

Why this matters
Farcaster already gives communities portable identity and signed social messages. Plaza makes the hosting surface small enough that a town, a venue, a classroom, a festival, or one person with a laptop can run the channel edge themselves.
The network remains global. The origin can stay local. That is the interesting part.
