Third-party software
Last updated October 31, 2026
Fenrir is not affiliated with, endorsed by, or sponsored by any project or company on this page. Nor with TikTok, nor with any game publisher. Fenrir works alongside these things; none of them has agreed to anything with us.
What you install yourself
Fenrir does not bundle, mirror or re-host any of these. It links to each project’s own site and you install it from there under that project’s terms. Installing it separately does not give Fenrir or its users permission from a game publisher. These projects update on their own schedule and can break Fenrir’s connection to a game without either of us having changed anything.
Runs your patched game. Install Patch or Open Game downloads a pinned player from mGBA's download host when needed, checking its size and SHA-256.
MPL-2.0. Downloaded separately from the Fenrir installer. Supply your own compatible original ROM; Fenrir does not include ROMs or saves.
Loads native scripts into GTA V. One release supports both the Legacy and Enhanced editions. Required, together with ScriptHookVDotNet, before Fenrir can install a GTA mode.
Story Mode only. Loaders, third-party superhero/disaster mods and character assets are not bundled; obtain them from their authors under their terms. Experimental GTA gameplay and external-mod compatibility are not yet verified.
Loads .NET scripts such as Fenrir's GTA runtime. Use it for GTA V Enhanced; it also supports Legacy.
Zlib license. Not bundled.
The original .NET script loader, for GTA V Legacy only.
Zlib license. Not bundled.
The client that loads these games' mod scripts. The Steam versions on their own cannot run them.
You need a legitimate copy of the game. Plutonium does not provide the game itself.
Loads the original game's custom Survival scripts. Download iw5-mod.zip from AlterWare's client archive; Fenrir links to it and does not bundle it. AlterWare is winding down and says its archived clients may not work after the 2026 Steam update.
Use your owned MW3 installation and compatible legacy game files. Client compatibility and Fenrir's expanded Survival actions require testing; current game updates and missing map assets can cause problems.
The client that loads custom scripts for Infinite Warfare. The stock Steam game cannot run them.
You must legally own Call of Duty: Infinite Warfare. IW7-Mod's own guide says the same and will not support unlicensed copies.
A Steam Workshop mod that registers real console commands in Black Ops 3. Fenrir binds a key to one of those commands, so the mod is what makes the bind mean anything.
You need the Steam copy of the game. The mod is its author's work, not ours: Fenrir links to it and never bundles or redistributes it.
Injects into the Unreal engine so commands can reach the game. The bridge mod Fenrir writes runs on top of it.
Loads the small plugin Fenrir uses to pass commands into the game.
A Minecraft server Fenrir sends commands to over RCON. This is the one Fenrir will download and set up for you if you ask it to, from Paper's own API — it is still their software, fetched from them. Fenrir also downloads a Java runtime from Adoptium for it, checks both against the SHA-256 their providers publish, and installs the server only after you accept the Minecraft EULA yourself. Fenrir does not include or download Minecraft maps.
Optional OBS scene control needs OBS Studio (version 28 or newer), which you install yourself from its own site. OBS Studio is open-source software under the GNU General Public License, version 2 or later. Fenrir controls it through the remote control built into OBS (obs-websocket); it does not include, modify or redistribute any part of OBS. The dedicated Stream with OBS page was removed in beta.72. Browser overlays and OBS docks remain available, separately from the planned built-in Stream Studio.
Earlier Video Editor and Stream Studio components
Video Editor and Stream Studio are not included in the current desktop beta. The following notices are retained for earlier implementations; they are not a current feature list. Video export uses FFmpeg and FFprobe, using the FFmpeg build that ships with Fenrir. This release does not include a caption-generation runtime, and automatic generation/setup is disabled. Stream Studio is Fenrir's own engine; its streaming protocol components include libdatachannel, libsrt and libopus, with their dependency notices. The list below describes those native components; their notices and source information accompany the package. Fenrir is not affiliated with OBS, CapCut or DaVinci Resolve.

What ships inside the installer
These are open-source libraries compiled into the application. Their license terms are listed because they are the ones that actually attach to a download of Fenrir.
Reads the TikTok LIVE event stream. This is the one that makes Fenrir work.
MIT (version 6.6.5, the version Fenrir ships). Fenrir still runs entirely on your PC rather than on a server of ours: that is how it keeps your stream and your viewers' data to itself.
Included with the Python engine for legacy web-window compatibility. The current application window uses native WinUI 3.
BSD 3-Clause
Creates phone connection QR codes locally in Fenrir.
BSD 3-Clause, with MIT-licensed portions. Version 8.2.
Creates and checks local phone TLS certificates in Fenrir.
Apache 2.0 or BSD 3-Clause. Version 50.0.2.
Bundled from beta.82 so Clip Studio, highlights, clip trimming and game recognition from recordings work without installing anything. An unmodified shared build (BtbN autobuild), kept as separate files so its DLLs can be replaced.
LGPL-3.0. Source: the FFmpeg link on this row. Our mirror of the exact build we ship: the next row.
Our mirror release of the FFmpeg build Fenrir ships.
LGPL-3.0
Art by desire: his background and icon for the Desire's Lab style. Shipped from beta.84 but off by default; it loads only after you turn on Use desire's art in Settings > Experience. desire's map packs are not bundled: they download from his GitHub only when you click Install.
Used with desire's permission. Not covered by Fenrir's own licence.
Libraries built into the bundled FFmpeg
FFmpeg's own build includes these libraries. From beta.82 the full licence text of every one of them, taken from the upstream source of the exact version built, ships in the app's third-party notices (THIRD_PARTY_NOTICES.txt). Parts of ZVBI (src/packet-830.* and src/pdc.*) are under the GNU GPL version 2 only. For at least three years from when you got your copy of Fenrir, KJS GAMING LLC will give anyone who asks the complete corresponding source code for those FFmpeg DLLs; ask at support@fenrirapp.com. The upstream source is github.com/zapping-vbi/zvbi at commit 34bb6f660c5c1bacd4a66cc7b22311e4ca3c1ab5.

Services Fenrir and this site talk to
What each one sees is set out in the Privacy Policy, including how long anything is kept.
Used by the optional Fenrir Discord bot: it checks whether followed Twitch channels are live through Twitch's official API.
Twitch is a trademark of Twitch Interactive, Inc. We are not affiliated with Twitch.
Supplies the signing TikTokLive needs to open a LIVE connection. Your TikTok username passes through it when a stream connects.
Named on the Risks page too, because it is the one part of the chain that is not on your PC.
The Fenrir Discord bot runs on Discord's API, and the bot dashboard asks Discord which servers you manage when you connect your account.
Hosts the database for Discord bot settings and records, plus hashed account references and report-attempt times for feedback spam prevention. It also coordinates billing updates; feedback text is not stored there.
When a member uses them, the Discord bot asks public services for an answer: Open Trivia Database (/trivia, questions under CC BY-SA 4.0), Wikipedia (/wiki and /anime summaries, CC BY-SA), Wikidata (/anime facts, CC0), dictionaryapi.dev (/define, definitions from Wiktionary under CC BY-SA) and bible-api.com (six of the Bible translations). Only the search words or the verse reference are sent. Feeds a server sets up are read from the YouTube Data API and the RSS address the server chose.
Bundled with the Discord bot, all free to use: the World English Bible (ebible.org, public domain), the Berean Standard Bible (public domain since 2023), the New Heart English Bible (public domain), and the King James, American Standard, Darby, Young's Literal and Geneva texts (public domain by age; the KJV is under a Crown patent in the UK only), from scrollmapper/bible_databases (MIT). Creeds, confessions and catechisms come from Creeds.json, keeping only the texts it marks Public Domain.
Holds accounts and sign-in. Your email address and the record that you accepted the terms live here.
Hosts this website and the account and plan API the application checks in with, and counts this website's page views (Vercel Web Analytics: no cookies, no cross-site tracking).
Hosts the installer download and the release list the updater reads.
Games
Call of Duty, Minecraft, Palworld, Valheim, Hogwarts Legacy and every other title Fenrir supports belong to their publishers. Fenrir is not licensed by, affiliated with or endorsed by any of them, and it does not provide a way to obtain a game. You need your own legitimate copy of any game you want to use it with, and modifying a game you own carries risks that are set out on the Risks page.
Something missing or wrong?
If you maintain one of these projects and want the wording changed, or want Fenrir to stop pointing at you, say so and it will be changed. Contact details are on the Terms page.
