Built for serious streamers
Every feature in StreamArc was designed around one goal: making your TikTok Lives more engaging without adding complexity to your setup.
Your stream, alive.
Animated Overlays
Design browser-source overlays that fire when your audience interacts. Follow alerts, gift animations, like bursts — all in real time, all customizable.
- Drag-and-drop overlay editor in the dashboard
- Multiple animation presets: alerts, banners, pop-ups
- Instant browser-source URL — paste into OBS and done
- Overlays persist across stream sessions
- Supports transparent backgrounds for compositing
Rules that run on your terms.
Smart Triggers
Build event-driven automations without code. Set a trigger to fire when someone sends a gift above a threshold, types a command in chat, follows your account, or hits a milestone.
- Gift threshold triggers (e.g., fire when gifts > 50 diamonds)
- Chat command triggers (e.g., !hype, !tts)
- Follow and like event triggers
- Subscriber milestone triggers
- Multiple triggers per overlay, independently configurable
- Free plan: 5 triggers · Pro: unlimited
Hear your audience, literally.
Neural Text-to-Speech
StreamArc's Kitten TTS engine runs entirely on your machine — no cloud API, no latency, no per-character costs. Gift messages and chat donations get read aloud in one of eight natural voices.
- 8 expressive voices: 4 male, 4 female
- On-device ONNX neural engine (Kitten TTS)
- Download once (~80 MB), works offline after
- Deterministic per-viewer voice assignment
- Web Speech API fallback before model downloads
- Volume control and voice selection in Settings
Every interaction, instant.
Real-time Event Feed
The desktop app's Live Feed tab shows a scrolling real-time log of every viewer action on your stream — follows, likes, gifts, chat messages — as they happen.
- Zero-delay event stream via TikTok Webcast protocol
- Color-coded event types for quick scanning
- Gift events show diamond value
- Feed persists across overlay windows
- Searchable and filterable by event type
More ways to engage.
Custom Widgets
Drop-in browser-source widgets to add extra engagement layers to your stream without cluttering your main overlay layout.
- Goal bars: track gift targets in real time
- Leaderboards: top gifters of the session
- Each widget has its own browser-source URL
- Styled to match your overlay theme
- Available on Pro plan
Stream tools that live on your machine.
Desktop App
StreamArc is a native Windows desktop application — not a browser extension, not a web app tab. It runs in the background while you stream, with a system tray icon for quick access.
- Windows installer via NSIS (no admin required)
- System tray: start/stop, open overlay, check status
- Auto-connects to TikTok when you go live
- OBS-compatible browser source URLs
- Settings sync between desktop and dashboard
Always up to date.
Automatic Updates
StreamArc checks for updates every time it launches and downloads them in the background. You're always on the latest version without thinking about it.
- Silent background downloads
- One-click install on next launch
- Minimum version enforcement for security
- Pre-release channel for early features
Your account, protected.
Security & Privacy
StreamArc uses isolated browser partitions for TikTok authentication and Clerk for dashboard auth. Your session credentials never leave your machine in plaintext.
- Isolated TikTok session (separate from your browser)
- Clerk-based authentication (no passwords stored by StreamArc)
- No analytics or telemetry on your stream content
- Encrypted session storage on disk
