Stream Chat Overlay

A lightweight, transparent chat overlay for Twitch and Kick — designed for single-monitor streamers who want to see chat without alt-tabbing.

Built with WPF/.NET 9. No browser sources, no Electron, no bloat.

Features

• Twitch + Kick chat in a single overlay window
• Transparent, always-on-top — sits over your game with no background
• Native emotes — Twitch, Kick, BTTV, FrankerFaceZ, and 7TV (including animated GIFs)
• Notification sounds — Chirp, Bubble, Chime, Drop, Ping with volume control and preview
• Resizable and draggable — position and size the overlay however you want
• System tray — minimize to tray, toggle borders, reset position from the context menu
• Font scaling — 10pt to 72pt with emotes that scale proportionally
• Dark-themed settings — clean settings panel, no ugly Windows-default dialogs
• Platform badges — Twitch and Kick logos next to each message
• Text shadow — readable on any game background
• No login required — connects anonymously to public chat (read-only)

Build from Source

Requires .NET 9 SDK.

dotnet publish src/StreamChatOverlay/StreamChatOverlay.csproj -c Release -o publish

Setup

Twitch

1. Open Settings (gear icon in title bar, or right-click tray icon)
2. Enter your Twitch username
3. Click Connect

That's it — no OAuth, no tokens. It connects anonymously to public chat via IRC.

Kick

1. Enter your Kick username in Settings
2. Enter your Kick Chatroom ID (see below)
3. Click Connect

Finding your Kick Chatroom ID

Your chatroom ID is a permanent number tied to your Kick account (it never changes).

1. Go to https://kick.com/api/v2/channels/YOUR_USERNAME in your browser
2. In the JSON response, find "chatroom": { "id": 12345678 } — that number is your chatroom ID
3. Paste it into the Kick Chatroom ID field in settings

If Cloudflare blocks the API page:

1. Go to kick.com/YOUR_USERNAME
2. Open DevTools (F12) > Network tab
3. Refresh the page, filter by channels
4. In the response JSON, find chatroom.id

Note: The chatroom ID is different from the channel ID. Make sure you use the one inside the "chatroom" object, not the top-level "id".

Usage

• Drag the title bar to move the overlay
• Resize using the grip in the bottom-right corner
• Hide borders — click the [ ] button or use the tray menu to make it fully transparent
• Show borders — right-click the tray icon > Toggle Borders
