Chat Box Overlay (16 Themes)

An overlay that shows your unified live chat (YouTube + Twitch + Streamlabs) directly on stream — a separate OBS Browser Source from the pop-out chat window (which is for the streamer). Great for streamers who want viewers to see chat on screen.

What it does​

  • Shows unified chat from all platforms on stream, with platform icons (you can upload a custom icon per platform)
  • Choose from 16 themes: dark, glass, minimal, bubble, neon, vtuber, cozy, terminal, sakura, comic, holo, kawaii, discord, rpg, sticky, lowerthird
  • Adjust font size (default 13px) + toggle timestamps
  • Fun effects — playful entry animations + bouncy highlights (seeded per message so they stay stable, no flicker)
  • Supports Chat Critters FX — a layer of playful effects on top of chat

Where to find it​

Config: Settings → Overlays → Chat Box

OBS Browser Source route: /chat-overlay — copy the URL from the app into OBS as a Browser Source

Settings → Overlays → Chat Box showing theme options, font size, and a chat overlay preview
Pick a theme + font size, then copy the /chat-overlay URL into OBS

Use case​

A just-chatting streamer who wants viewers to see chat nicely on screen — pick the bubble or discord theme, bump the font size for readability, and drop /chat-overlay into OBS. YouTube + Twitch chat shows up together on stream instantly.
