Evidence

Things with no honest explanation: a promise that contradicts the code, code that runs at install time while hiding what it does, data leaving the machine.

Orionbelt Semantic Layer — questions

Answers built from our own checks of this server.

Why is there no uptime for Orionbelt Semantic Layer?

Orionbelt Semantic Layer runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the pypi package orionbelt-semantic-layer was installed 626 times last week.

How do I connect Orionbelt Semantic Layer?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls orionbelt-semantic-layer straight from pypi; nothing to host, nothing to sign up for.

How many people use Orionbelt Semantic Layer?

The pypi package orionbelt-semantic-layer was installed 626 times in the last week. Week over week that is -23%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Orionbelt Semantic Layer open source?

We cannot say either way: written in Python and 94 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
