Free tier — no card required

Your backends, unified.
One URL. Stays alive.

WatsonLB sits in front of your scattered free-tier backends on Render, Railway, Fly.io — and routes traffic intelligently. If one goes down, traffic moves to another. If all are cold-starting, your requests queue and flush automatically instead of returning 502.

# Before WatsonLB
BACKEND_URL=https://myapp.onrender.com  # 💀 single point of failure

# After WatsonLB
BACKEND_URL=https://watsonlb.dev/p/a1b2c3d4/
# Routes to: render.com → railway.app → fly.io
# Request queue: holds cold-start requests → flushes when backend wakes

What WatsonLB does

⟳
Round-robin routing
Traffic distributed across all your backends. Unhealthy ones are skipped automatically.
⚡
Request queue
Free-tier apps cold-start in 10–30s. We hold the request and flush it when the backend wakes up — no 502.
◉
Health monitoring
Pings every backend every 5 minutes. Circuit breaker opens after 3 failures. Dashboard shows live status.
☀
Morning reports
Email at 8am with exactly what happened while you slept. Uptime percentage, downtime windows, response times.
🛡
Shield middleware
Blocks bad user-agents, path traversals, and rate-limit offenders before they hit your backend.
↗
Real-time alerts
Instant email (and WhatsApp on Pro) within 60s of a backend going down. Fix it before users notice.
