StreamLight is the official FoggyBytes fork of Moonlight with native StreamTweak integration. It adds host NIC control, live host metrics in the overlay, store badges on game covers, and session quality reporting — all from the client side.
Windows 10 and 11. Requires StreamTweak running on the host PC for StreamTweak-specific features.
⚠️ Not affiliated with or endorsed by the Moonlight project. StreamLight is an independent fork. For upstream Moonlight support, use the official client.
🔗 NIC Control from the Client
- Right-click any paired host to send the speed-change command before connecting, with a built-in 10-second countdown and auto-revert if no connection follows within 30 seconds
- Show current host NIC speed without starting a stream
🖥️ Host Metrics in Overlay (requires StreamTweak 4.4.0+)
- Live GPU %, encoder %, GPU temperature, VRAM used/total, CPU %, and network TX displayed in the performance overlay
- Section hidden entirely when StreamTweak is unreachable — no visual clutter
🎮 Store Badges on Game Covers (requires StreamTweak 5.0.0+)
- Per-game store badge (icon + name) overlaid bottom-right on each cover: Steam, Epic Games, GOG, Ubisoft Connect, Xbox, Battle.net, EA App
- Fetched live from the host via the APPSTORES command on the TCP bridge
📋 Session Quality Report (requires StreamTweak 5.2.0+)
- Client-side metrics (FPS, frame drops, RTT, jitter, decode latency, bitrate) streamed to StreamTweak every second during the session
- StreamTweak uses this data to generate a quality grade (Excellent / Good / Poor) and sparkline charts visible in the Logs tab
⏸️ Remote Session Pause (requires StreamTweak 6.0.0+)
- StreamTweak's Home page shows a Pause button when a session is active; pressing it terminates the stream on the client side exactly as if the user had pressed Pause locally
- Signal piggybacked on the existing per-second STATS channel — no new connection or protocol change required
💡 Philips Hue Sync Integration
- Optional toggle in Settings to automatically start Philips Hue Sync on the client PC when a streaming session begins and close it when the session ends
- Launched silently in the background using HueSyncStarter.exe — no window appears; install path resolved via the Windows Uninstall registry, so custom install locations are supported
🎨 Visual Identity
- UI fully aligned with StreamTweak — color palette, spacing, and component styling match across both apps
- App list sort order: Desktop first, Steam Big Picture second, all others alphabetically
- Session telemetry send interval — SESSIONDATA is now sent once per second instead of every 10 seconds; StreamTweak's live session charts on the Home page update every second as intended (requires StreamTweak 6.1.0+)
2.3.0 — "The Remote Pause Update"
- Remote session pause — StreamTweak's Home page now shows a Pause button when a session is active; pressing it stops the stream on the client side with no UI changes required in StreamLight (requires StreamTweak 6.0.0+)
For full version history see changelog.txt.
StreamLight communicates with StreamTweak over a plain TCP bridge on port 47998 (LAN). Commands: PREPARE, RESTORE, STATUS, STATS, APPSTORES. The same bridge is used to send NIC commands from the client side and to receive host metrics and store data.
