stella observe
See a local dashboard of what stella has been doing on your machine. It only runs on your computer and never sends data out.
The Observatory is a read-only dashboard that shows you what stella has been doing. It reads local data from .stella/private/store.db and .stella/private/fleet.db. The Observatory never sends this data anywhere else. It only listens on 127.0.0.1, meaning your own computer, even if your organization has turned on an Enterprise adapter that collects a small summary of activity elsewhere.
Synopsis
stella observe [--port <N>] [--open]What it does
stella observe starts a small web server on your computer (port 7787 by default) and shows you the dashboard. You don't need to install anything extra or build anything first. The server only listens on your own machine, and stella observe never sends data anywhere else.
It reads the same local files that every stella command writes to. That means it works in any workspace where you've run stella at least once. You don't need an API key.
Data can only leave your machine through the two paths described on the telemetry page. This command does not use either of them.
Dashboard tabs
The dashboard covers:
- Overview
- Executions, with details for each run
- The code graph
- Skills
- MCP traffic
- Memory
- Self-improvement
- Your resolved config
It also shows model spend, fleet runs, and a way to change the time range for the charts. See the Observatory dashboard page for a tour of each tab.
Flags
--port <N>The port to use on 127.0.0.1. Set it to 0 to let stella pick a free port for you.
Default 7787
--openOpens the dashboard in your default web browser once the server starts.
Examples
Serve the dashboard and open it:
stella observe --openUse a random open port (handy if 7787 is already taken):
stella observe --port 0Use one fixed port so a bookmark always works, and run it in the background:
stella observe --port 8080 &See a different workspace's data by running the command from that workspace's folder:
(cd ~/projects/acme && stella observe --open)
