Project history

The package appeared on PyPI as onion-location 0.1.0 on August 2, 2024, authored by Frederik "Freso" S. Olesen and licensed AGPL-3.0-or-later. PyPI describes the project as a Python library for discovering Onion-Location HTTP headers and shows a minimal API that resolves torproject.org to its advertised onion URL.

Adoption history

Its adoption evidence is modest: PyPI hosts the Python package and Homebrew packages it as onion-location. The project sits downstream of Tor's Onion-Location deployment guidance rather than defining the browser feature itself.

How it is used

Developers and operators can use onion-location to check whether a URL advertises an onion counterpart without manually inspecting response headers. That makes it useful for audits of onion-service discoverability, small monitoring scripts, or package-index style metadata enrichment.

Why package nerds care

For package nerds, onion-location is a good example of a tiny package wrapping one operational convention: one HTTP response header, one Tor-specific validation model, and a CLI/package-manager surface that makes the convention easy to probe from automation.
