| programming:tranco [2026/08/27 14:14] – CrUX licence: Tranco methodology still CC BY-SA 4.0; Google methodology is CC BY 4.0. Authored by Claude karel.kubicek.claude | programming:tranco [2026/08/27 14:39] (current) – CrUX licence line: Tranco homepage not methodology. Authored by Claude karel.kubicek.claude |

| **Farsight is default-list-only.** The homepage says so ("only for the default list"), and the [[https://tranco-list.eu/api_documentation|API documentation]]'s ''Configuration.providers'' enum is ''crux | majestic | radar | umbrella | alexa | quantcast''. A custom list you generate through ''PUT /lists/create'' cannot include the Farsight ranking that the daily list uses. If you need a 2026-shaped list that is not the daily one, you are generating something **stricter** than the default, not a clone of it. | **Farsight is default-list-only.** The homepage says so ("only for the default list"), and the [[https://tranco-list.eu/api_documentation|API documentation]]'s ''Configuration.providers'' enum is ''crux | majestic | radar | umbrella | alexa | quantcast''.

| Licences on the current default inputs, as Tranco states them: Umbrella free of charge; Majestic CC BY 3.0; CrUX **CC BY-SA 4.0 on Tranco's methodology page**; Cloudflare Radar **CC BY-NC 4.0**; Farsight used only in the default list. Google's own CrUX methodology (fetched 2026-08-27) licences the datasets **CC BY 4.0**, not CC BY-SA — use that when you cite CrUX directly. Radar's non-commercial clause is the one that bites if you ship the default list as part of a product. Tranco is not affiliated with the providers. | Licences on the current default inputs, as Tranco states them on its homepage (fetched 2026-08-27): Umbrella free of charge; Majestic CC BY 3.0; CrUX **CC BY-SA 4.0**; Cloudflare Radar **CC BY-NC 4.0**; Farsight used only in the default list.

| The public GitHub repository ([[https://github.com/DistriNet/tranco-list|DistriNet/tranco-list]]) still has ''DEFAULT_TRANCO_CONFIG'' as Alexa + Umbrella + Majestic + Quantcast, ''listPrefix: full''. Last push: **2020-03-05**. It is the 2019 generator, not the live service. Do not read the current default out of that file. | The public GitHub repository ([[https://github.com/DistriNet/tranco-list|DistriNet/tranco-list]]) still has ''DEFAULT_TRANCO_CONFIG'' as Alexa + Umbrella + Majestic + Quantcast, ''listPrefix: full''.
