What is it?

OhMyBuddy is a self-hosted web app that runs on your own computer and turns the Pi coding agent into a personal assistant you can reach from a desktop browser, a phone, or WeChat. It bundles two parts on one runtime: Buddies, named assistants with their own personality and long-term memory, and a Workspace for project work with threads, streaming tool calls, diffs and subagents.

Memory is designed to be inspectable. When a reply saves a note, a skill or a setting, a receipt appears under the message, and memories and skills can be reviewed, edited or undone. Sessions are stored as Pi's native JSONL files, so they remain compatible with Pi CLI. You bring your own model keys for providers such as Anthropic, OpenAI, Google Gemini, DeepSeek, Qwen and Kimi.

The project runs natively on Linux, macOS and Windows, uses Node.js 22.x, and needs no build step or GPU. It also includes scheduled tasks, MCP support, an extension manager, a media lab for image, video and speech services, and an optional WeChat connector based on ClawBot (iLink). The access token is designed for personal, single-user use.
