The Synapse gallery

Built with Synapse. Running in a host you own.

Real MCP apps, each a typed UI built once with Synapse. They ship to ChatGPT and Claude, and come alive self-hosted in NimbleBrain, the host that gives them an agent, memory, and multi-tenancy.

HOST

Built with Synapse. Home in NimbleBrain.

Synapse builds each app's UI once. The same app runs in the public stores (ChatGPT, Claude, VS Code) and comes home to NimbleBrain, the host you own, where it gains an agent that drives it, persistent memory, and multi-tenancy.

In NimbleBrain, the host you own, apps also gain an agent that drives them, persistent memory, and multi-tenancy.
