The creator: "under Live->Layers->webcam->Properties->border color: in the drop down box, the #hex values are good, but add a corresponding color name/label next to the value." Each row now reads "#e94560 Crimson" - the hex stays exactly as it was, the colour's name goes next to it (dimmed #a0a0b0 so the hex reads first), and the tooltip becomes "Crimson (#e94560)". The 14 colours were a hard-coded string[] inside the click handler - a list of bare strings cannot carry a name, and a list hidden in UI code cannot be asserted on. They now live in Models/BorderColorPalette.cs: NamedColor(Hex, Name) + BorderColorPalette.All (the single source of truth) + NameOf(hex), which answers case-insensitively and falls back to the hex for a colour outside the palette. The picker builds its menu from the catalogue and no longer knows any colour by heart. The names are chosen not to collide - the palette has two greens, two blues and two warm colours: #00FF00 is Lime and #22c55e Emerald, #0000FF is Blue and #3b82f6 Azure, #FF8800 is Orange and #f59e0b Amber. Guard: ytLive.Tests/BorderColorPaletteTests.cs - every entry valid + named, no hex or name repeated, the 14 legacy colours all still offered, NameOf answers, and the old list is gone from the handler. 433/433 green, 0 warnings.

Why I built it
I'm Gramps. I've been gaming since 1981, and these days I stream The Division 2 on YouTube.
When I started streaming, I did what everybody does: I installed the big, general-purpose streaming tools. They're excellent software — powerful, flexible, and built to handle every platform, every camera rig, and every plugin anyone has ever dreamed up. That breadth is exactly what makes them great, and it's also what makes them a lot to learn. Before my first stream I was reading setup guides, picking encoders, balancing audio by hand, and wiring up scenes from scratch. The tools were ready for anything. I just wanted to go live.
Most streamers I talk to are in the same spot. They don't need a tool for every platform and every setup — they need one that's ready for theirs. So I built LlamaCasty around three choices:
- One platform, done properly. LlamaCasty streams to YouTube and only YouTube. That focus lets it be built around how YouTube Live actually works — your channel, your chat, Super Chats and memberships, Shorts-style vertical video, and the YouTube Partner Program — instead of treating YouTube as one destination among many.
- Ready the moment you open it. Five scenes (Starting, Live, BRB, Chat, Ending) are set up, your game and voice are balanced with auto-ducking and voice polish built in, and YouTube's settings are filled in. You arrange things by dragging them, then press Go Live.
- Calm while you're live. A private Test Stream to practice, a layout that locks while you're on air, and warnings only when YouTube reports a real problem.
The general-purpose tools are the right choice when you need everything. LlamaCasty is for when you just want to get your show on air.
Free, and staying that way
LlamaCasty is free forever: no watermark, no branding on your stream, no subscription, no LlamaCasty account. It's also open source (see License) — enjoy it, explore it, experiment with it. If it earns a spot in your setup and you'd like to say thanks, there's a coffee jar and a merch store linked from https://llamacasty.com. Completely optional, never expected, and the app will never ask.
How it's built
LlamaCasty is built through AI-assisted pair programming, under the direction of a developer with decades of experience. Architecture, product direction, and quality gates are human-owned; AI speeds up the implementation. The repo's memory map (below) is how that collaboration stays honest from one session to the next.
Requirements
- 64-bit Windows 10 or 11. (The bundled FFmpeg and ONNX Runtime are 64-bit only.)
- A YouTube channel, to stream. LlamaCasty links an existing channel with "Sign in with Google" — it doesn't create accounts. Recording to an .mp4 works without signing in.
- Working sound in Windows. Desktop and game audio come from your default output automatically; you choose your mic in the app. LlamaCasty doesn't diagnose or repair Windows audio — if it doesn't sound right in Windows, fix it there first.
Build from source
The internal project, assembly, and namespace names are still ytLive (the app was renamed to
LlamaCasty; the internals weren't). Building needs Windows and the .NET 8 SDK.
-
Fetch the bundled FFmpeg (not in git — ~135 MB, pinned and SHA-256-verified):
scripts/fetch-ffmpeg.sh -
Add your own Google OAuth client.
Helpers/OAuthCredentials.csis gitignored. Create a "Desktop app" OAuth client with the YouTube Data API v3 enabled in Google Cloud Console, then:namespace ytLive.Helpers; public static class OAuthCredentials { public const string ClientId = "your-client-id.apps.googleusercontent.com"; public const string ClientSecret = "your-client-secret"; } -
Build and run:
dotnet build ytLive.csproj dotnet run --project ytLive.csproj
Version roadmap
v1 is the finished product (no v1.x releases are planned). Everything still in the queue lands
in v1; anything not on the feature list is on the "Out of product — permanently" list in
TASKS.md — read that before asking for a feature.
What v1 ships: the five-scene control surface, webcam + screen capture, media + web + text sources, chat on stream, the social bar, mic/desktop audio with auto-ducking and TRAX background music, local recording, quality tiers including vertical 9:16, one-click go-live + scheduling, stream resilience, monetization awareness (YPP tracker), animated alerts, and webcam background removal and blur — all free and ungated.
