Features

Simultaneous multi-platform support

• Twitch — Anonymous IRC or OAuth, with badges, subs, rewards, and bits.
• Kick — Pusher WebSocket connection, no authentication required.
• YouTube Live — Anonymous InnerTube support, Super Chats, and member subscriptions.
• TikTok Live — Real-time event tracking including comments, new followers, and subscriptions.

All at the same time, in a single HUD.

Real animated emotes

• 7TV global + channel emotes, including zero-width overlays (RainTime, overlays on top of other emotes).
• BTTV + FFZ support on Twitch.
• Native Twitch emotes.
• Unicode emojis → Twemoji.
• Locally decoded static WebP images (no proxy required).
• Custom GIF decoder with proper disposal method support, packed into a 2D atlas: 1 GL texture per animated emote, automatically split if it exceeds `GL_MAX_TEXTURE_SIZE`.
• Disk cache with a 7-day TTL — instant startup after the first session.

Polished overlay

• Display modes: FULL · COMPACT · MINIMAL.
• Themes: DEFAULT · DARK_GLASS · PREMIUM_GLASS · QSMP · MINIMAL_WHITE · CUSTOM.
• Animations: configurable fade-out lifetime and horizontal slide-in.
• Duplicate collapsing (`x3`, `x7`, …).
• Avatars + platform icons + official platform badges.
• Adaptive username contrast.
• Swappable layout profiles.

Interaction

• Highlighted mentions with optional sound.
• Follower, Subscription and Donation notifications.
• Word and user blocklist.
• Highlighted users (`specialUsers`) and alert tracking (`wantedUsers`).
• Keybinds to hide/show, clear chat, and cycle display modes.

Privacy

NexusChat only connects to the official APIs of each platform:

• `twitch.tv`
• `7tv.io`
• `betterttv.net`
• `frankerfacez.com`
• `kick.com`
• `youtube.com`
• `tiktok.com`

It also uses `wsrv.nl` as an image proxy only as a fallback.

There is no dedicated server and no user data is collected.
