Bullpen.sh
Stock and portfolio research through your own coding agent
Desktop app for stock and portfolio research through coding agents like Claude Code, Codex, and Gemini. Reports with sources. Your keys, your keychain. Data stays on your machine.
I've been building Bullpen.sh lately. It's one of a few "one-skill-apps" I'm working on, all following the same pattern: a thin layer of opinionated GUI + data structure on top of my local coding agents. All using the combo of Tauri + AgentClientProtocol + MCP. Super strong
The idea is simple. I take something I do over and over freeform with an agent. Put structure around it. Force the agent to submit findings in a schema, store it in a structured DB, and visualize it.
So far these mini one-skill-apps perform better for me than raw agents + skills. Not sure they're 10x better for anyone else, but they're 10x better fit for my needs than just using the agent itself.
