A daemon that runs your stream,
not the other way around.
StreamDaemon is a free, open-source, self-hosted toolkit for Twitch: 57+ themed overlays, real-time chat, giveaways, predictions, subathons, anti-bot protection, and analytics — all in one local app. No subscriptions. No cloud. Your data stays on your machine.
Most stream tools rent you your own setup.
StreamDaemon runs as a local process on hardware you own. No login wall, no vendor lock-in, no monthly fee to keep your overlays alive.

Everything a stream process needs to stay alive.
Every module talks over Socket.IO in real time, so what happens in chat shows up on screen instantly.
57 standalone overlays
Pure HTML/CSS/JS, no framework required. Eight themed styles including Subnautica 2, Fortnite, Retro 8-bit, Win95, and RetroWave — start screens, gameplay, BRB, and farewell states included.
Vertical & animated
12 vertical overlays (1080×1920) for mobile and dual-format streaming, plus animated alerts for follows, subs, raids, cheers, and redemptions.
Live in-app preview
An interactive preview with dynamic scaling and simulated Demo Mode data, so you can design overlays without going live.
Real-time Twitch IRC
Live chat relayed to overlays instantly, with TTS voice selection, speed and filters, and auto-greetings for new chatters.
Giveaways & predictions
Weighted-ticket giveaways with an animated wheel, plus Twitch Predictions with automatic resolution.
Custom commands
Aliases and cooldowns for every command, so your chat runs itself while you focus on the game.
KPI dashboard
Historical stats across 7d, 30d, 90d and all-time, plus Twitch Achievement tracking for Affiliate and Partner milestones.
Stream HUD & scoreboard
Live viewer, follower and sub counts, a Fighter Overlay and scoreboard for tournaments, and a Fortnite stats overlay for kills, wins and K/D.
Encrypted & rate-limited
OAuth tokens encrypted with AES-256-GCM, local API auth on every request, anti-bot protection, and Zod-validated input on all routes.
Built on a stack that stays out of your way.
Two ways to run the daemon.
Zero-config on Windows, or self-hosted anywhere Node runs. You'll need a free Twitch Developer Application either way.
