OMPiUI is a third-party web/desktop client for OMP (oh-my-pi): the interface reuses the PiUI visual shell, while agent execution is powered by the official oh-my-pi (OMP) RPC runtime with 60+ providers, 31 built-in tools, a sub-agent system, MCP/LSP, and extensions.
The interface comes from lehhair's PiUI and OpenCodeUI. OMPiUI is not an official client of either project.
It requires Node 22.19 or later and the OMP CLI (18.2.11 or later, installed with bun install -g @oh-my-pi/pi-coding-agent), with provider credentials configured.
