Its package-nerd interest is less about a large standalone ecosystem and more about turning a Tor Browser convention into a scriptable CLI/library primitive. ### 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. ### Timeline - 2020: Tor Browser 9.5 introduced user-facing Onion-Location support, giving HTTPS sites a browser-visible way to advertise onion services. - 2024-08-02: onion-location 0.1.0 was released on PyPI. - 2026: Homebrew distributes onion-location as a formula with the same advertised purpose. ### Related projects - The project is related to Tor Browser's Onion-Location feature, Tor onion services, and broader onion-service discovery work. ### Sources - - - - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** onion-location - **Version Scheme:** 0 - **Revision:** 2 - **Head Version:** HEAD - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## Related links - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Language runtime packages](https://www.automicvault.com/pkg/language-runtime-packages/) - Matched language runtime, compiler, or interpreter metadata. - [Networking and protocol packages](https://www.automicvault.com/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [Web development packages](https://www.automicvault.com/pkg/web-dev-tools/) - Matched web development metadata. - [python@3.14](https://www.automicvault.com/pkg/brew/python-3-14/) - Runtime dependency declared by Homebrew. - [nyx](https://www.automicvault.com/pkg/brew/nyx/) - Shares av.db curated category or tags: cli, networking, tor. - [onionprobe](https://www.automicvault.com/pkg/brew/onionprobe/) - Shares av.db curated category or tags: cli, networking, onion-services, tor. - [airshare](https://www.automicvault.com/pkg/brew/airshare/) - Shares av.db curated category or tags: cli, networking, python. - [dsocks](https://www.automicvault.com/pkg/brew/dsocks/) - Shares av.db curated category or tags: cli, networking, tor. - [gdown](https://www.automicvault.com/pkg/brew/gdown/) - Shares av.db curated category or tags: cli, networking, python. - [geoip2fast](https://www.automicvault.com/pkg/brew/geoip2fast/) - Shares av.db curated category or tags: cli, networking, python. - [getmail6](https://www.automicvault.com/pkg/brew/getmail6/) - Shares av.db curated category or tags: cli, networking, python. - [magic-wormhole](https://www.automicvault.com/pkg/brew/magic-wormhole/) - Shares av.db curated category or tags: cli, networking, python. - [podcast-archiver](https://www.automicvault.com/pkg/brew/podcast-archiver/) - Both packages touch the same language runtime or ecosystem.
