multiplehats/eve-studio

eve-studio is a debugging and monitoring tool for developers building AI agents with a framework called eve. Instead of digging through raw log files to understand what an agent did, this tool gives you a browser interface that shows live sessions, the messages exchanged, the steps the agent took, which tools it called, and how much it cost in tokens and money. It works by adding a small extension to an existing eve agent project. That extension sends a stream of events about what the agent is doing to a local collector program, which organizes those events into a readable session history. A web page served next to your agent then lets you browse each session, see its status such as working, waiting, completed, or failed, and inspect the full timeline of messages and tool activity. Getting started is meant to be quick: running a single command from inside an eve agent project sets up the extension and starts the collector and browser UI automatically. There is also an option to load past sessions that were already saved to disk. Setup requires Node.js 24 or newer and a specific compatible version range of the eve framework itself, so this tool is only useful if you are already building with eve. The tool is built to run entirely on your own machine. The collector only listens on your local computer, not the open internet, and nothing is uploaded anywhere. It will not capture data in a production environment unless you explicitly turn that on with an environment variable, and if the collector is not running, the extension simply drops old events rather than slowing down or breaking your agent. The project is a workspace made up of a CLI, a collector server, a browser interface, and a demo agent used for testing. The author describes it as early, beta software that follows preview APIs of the eve framework, so its behavior may still change before a stable release.
