yt-dlc-yt-dlp · status confirmed
Data verified at: 2026-11-14T00:01:35.175Z (UTC)
A human reviewer approved this relationship for the exact current evidence at 2026-09-20T08:19:11.135Z (UTC). The evidence below is the basis of that decision.
Evidence suggests yt-dlp/yt-dlp is a fork of blackjack4494/yt-dlc. Human review required before publication.
Seed context: 2026-09-19 researched candidate; NOT APPROVED. New README explicitly identifies now inactive youtube-dlc as its base; continuing maintenance and release verified. Community continuation, not exclusive official successor of youtube-dl. Primary sources: https://github.com/yt-dlp/yt-dlp and https://github.com/blackjack4494/yt-dlc. Raw API evidence: succession-research-20260919.json. Await normal collector ingestion; API quota exhausted.
Verbatim excerpts from official sources, whitespace-normalized. Full payloads are hashed and retained by the pipeline; collection failures never fabricate evidence.
The project is a fork of youtube-dl based on the now inactive youtube-dlc.
As of the last verified collection. These are facts about the snapshots, not activity verdicts — a low number is not a claim that a project is inactive.
