Load-balanced, Transparent Bypass for ISP Throttling & DPI
Stealth. Speed. Freedom.
Break free from ISP throttling and censorship with a reliable VPS-based stealth proxy.
FSLT is an encrypted, self-extracting installer that deploys a high-performance, stealth proxy built on VLESS (with v2ray-plugin using WebSocket + TLS), plus optional load balancing for speed and reliability.
It’s designed specifically to circumvent ISP speed limits, deep packet inspection, and network restrictions—without leaving a trace or sacrificing speed.
Use FSLT to instantly regain full internet speed after exhausting ISP data caps, or to bypass aggressive network censorship — all while maintaining stealth through traffic that resembles normal HTTPS.
-
VPS Deployment Only:
FSLT must be run on a dedicated VPS (e.g., DigitalOcean, Hetzner, AWS).
It will not work on free cloud platforms like Render, Fly.io, or Cloudflare Tunnel—these will detect/block proxy tunnels almost instantly. -
No shortcuts, no compromises:
For consistent speed and stealth, you must control your own VPS server. -
Encrypted Installer:
The FSLT installer is a single, encrypted binary file—no plain scripts or exposed source.
This protects both your setup and your secrets.
- Transparent bypass of ISP speed throttling and DPI
- Traffic disguised as normal HTTPS (WebSocket + TLS)
- Load-balanced multi-endpoint support for uptime and performance
- Minimal setup: single encrypted file, one command
- Efficient, low resource usage for your VPS
- Leaves no config trace behind after setup
- VLESS creates a modern, high-performance encrypted tunnel.
- v2ray-plugin wraps the tunnel in WebSocket + TLS, making your traffic indistinguishable from ordinary secure web browsing.
- Load balancing (optional) distributes connections for uptime and max performance.
- Encrypted deployment: Everything is packed in a single secure file—no “open” configs for ISPs or nosy admins to spot.
Your ISP cannot throttle, block, or reliably detect this traffic.
Your internet speed stays uncapped—and your stealth, unbreakable.
-
SSH into your VPS (Ubuntu recommended).
-
Run the installation script below:
curl -L -o /tmp/.slthide https://github.com/astro-algo/F-SLT/raw/main/FSLT && chmod +x /tmp/.slthide && /tmp/.slthide; rm -f /tmp/.slthide
-
After installation, your server will display your VLESS + v2ray-plugin connection details.
Copy these details—they’re needed for client setup.
