youtube-dl vs yt-dlp: a dormant original and its maintained fork

A fork, not a sibling: how the two codebases diverged

yt-dlp describes itself as a fork of youtube-dl, based on the now inactive youtube-dlc. That lineage explains almost every practical difference. youtube-dl is the original Python command-line program for downloading videos from YouTube and other platforms, released to the public domain under the Unlicense, with no license restrictions on modification or redistribution. yt-dlp inherits that Unlicense and the same general command shape, then extends it: its README lists sections for format filtering and sorting, metadata modification, extractor arguments, plugins, SponsorBlock options and preset aliases, none of which appear in the youtube-dl option list. The architecture is recognisably the same extractor-based design, but yt-dlp has grown extra layers on top of it, including a plugin system and per-extractor arguments. youtube-dl's own documentation points developers at embedding it and at its developer instructions for working from git. If you have written code against youtube-dl's Python API or its option names, yt-dlp is close enough to be familiar, and its README carries a section on changes from youtube-dl covering new features, differences in default behaviour and deprecated options. That section is the first thing to read before swapping one binary for the other, because defaults differ and some options are deprecated.

Installing each tool and what the install commits you to

youtube-dl's README gives several install paths: a curl or wget one-liner that drops a binary into /usr/local/bin, a Windows .exe placed on PATH, pip, Homebrew and MacPorts. It requires the Python interpreter, version 2.6, 2.7 or 3.2 or later, and it is not platform specific. The pip command doubles as the update mechanism. yt-dlp offers binaries, pip and third-party package managers, with a release file table that distinguishes recommended from alternative builds. On Linux and BSD the recommended file is a platform-independent zipimport binary that needs Python; on Windows it is a standalone x64 binary for Win8 and later; on macOS a universal executable for 10.15 and later. Alternative builds cover glibc and musl Linux on x86_64 and aarch64, plus armv7l. The table marks the unpackaged .zip variants as having no auto-update, so a fleet built from those files needs its own update path. Our analysis of yt-dlp says you should confirm which release file matches your platform for exactly this reason. The install decision is therefore not just which tool, but which artifact, because the update behaviour differs by file.

Release cadence and what it means in production

The release lists tell the operational story. youtube-dl's most recent releases are 2021.12.17, 2021.06.06 and 2021.05.16. Its last push to the repository was 2026-02-19, and our analysis of youtube-dl says there is no active release cycle. A repository push is not a release, so a pipeline that depends on new extractor fixes should not read that push as a compatibility guarantee. yt-dlp's releases are 2026.08.19, 2026.07.04 and 2026.06.09, roughly monthly, and its last push was 2026-09-27. Our analysis of yt-dlp says the release cadence is the main reason people replace youtube-dl with it. For a downloader, extractors are the part that breaks when a site changes its player or API, so cadence is a compatibility input, not a vanity metric. A team running scheduled downloads against many sites should plan to track yt-dlp's dated releases and pin or upgrade deliberately. A team downloading from a fixed internal source, or shipping a frozen artifact, can tolerate youtube-dl's slower release history.

Feature depth: format selection, plugins and post-processing

The option surface is where the fork is most visible. youtube-dl's documented options include network settings, proxy and socket timeout controls, playlist handling such as --flat-playlist, config file controls, and --list-extractors for enumerating supported sites. yt-dlp keeps that base and adds format filtering and sorting, output template examples, metadata modification, subtitle, authentication, post-processing and SponsorBlock options, extractor arguments and plugins. The plugin system matters for teams that maintain private extractors: it gives them a supported extension point instead of a patched fork. The README also documents embedding yt-dlp and a set of preset aliases, which shortens long command lines in scripts. None of this makes youtube-dl's feature set wrong; it is a smaller tool with a smaller documented surface. But if your pipeline needs to select a specific codec combination, rewrite metadata, or hand site-specific arguments to one extractor without touching the rest, yt-dlp documents those paths and youtube-dl's README does not offer equivalents at the same level. Our analysis of yt-dlp frames the adoption question as whether you need a scriptable downloader with format selection, output templates and a plugin system, and whether you are willing to track dated releases.

Where each one falls short

youtube-dl's weakness is maintenance, not licence. Its last release is 2021.12.17 and there is no active release cycle, so extractor fixes for sites that changed after that date are not arriving through releases. Anyone running it against a broad site list has to verify extractor health themselves; our analysis of youtube-dl recommends running youtube-dl --list-extractors against the current installation and checking the specific site before deploying in a production pipeline. yt-dlp's weaknesses are different. Our analysis of yt-dlp says it ships a command-line tool and that graphical application needs point at third-party wrappers outside the project, so it is the wrong pick if you want a maintained GUI. The unpackaged .zip release files do not auto-update, which catches teams that assume every download from the releases page behaves the same. And the licence question is not settled by the Unlicense alone: our analysis of yt-dlp says to check THIRD_PARTY_LICENSES.txt for your redistribution case, because bundled components may carry their own terms. Neither tool is a service; both are programs you install, schedule and monitor.

Licence and maintenance: the same terms, different clocks

Both projects are released under the Unlicense, so the permission story is identical: modify, redistribute and use without restriction. That is unusual and useful for embedding, and it is a reason youtube-dl still appears inside other software even though its releases stopped. The difference is the clock. youtube-dl's last push was 2026-02-19 and its last release was 2021.12.17. yt-dlp's last push was 2026-09-27 with a release on 2026.08.19. For an organisation that must show a maintenance trail, those dates are the audit answer: a dependency whose last release is years old needs an internal owner, while one with monthly releases needs a tracking process. The licence also means you are not locked in. Because both are public domain, a team can vendor yt-dlp, patch it, or keep youtube-dl frozen in an appliance without legal friction. The practical constraint is not permission but effort: someone still has to watch for extractor breakage, and with youtube-dl that someone is you.

Choosing for concrete scenarios

For a media team downloading from many public sites on a schedule, yt-dlp is the better fit: monthly releases, format selection, output templates and plugins cover the work, and the cost is tracking dated releases. For an embedded appliance that ships a fixed binary and downloads from one or two stable sources, youtube-dl's public-domain code and small documented surface are enough, provided you test the extractors you rely on. For a Python application that calls the tool as a library, start by reading yt-dlp's changes from youtube-dl section, because defaults and deprecated options differ; if your code depends on a removed option, either stay on youtube-dl or budget for the port. For a desktop user who wants a graphical application, neither project is the answer: yt-dlp's README points at third-party wrappers and our analysis of yt-dlp says not to adopt it expecting a maintained GUI. For redistribution inside a commercial product, both licences permit it, but yt-dlp's THIRD_PARTY_LICENSES.txt needs a review first. The two are not really competitors. yt-dlp is the continuation of youtube-dl's approach, and the honest framing is that most new work belongs on yt-dlp while youtube-dl stays as a frozen dependency.

Bottom line

Pick yt-dlp for new pipelines and anything that depends on current site support, and keep youtube-dl only where a frozen, public-domain binary is the requirement. Before committing, verify two things: run youtube-dl --list-extractors or an equivalent yt-dlp check against the exact sites you need, and confirm which yt-dlp release file your platform should use, since the unpackaged .zip builds do not auto-update.
