ScanMeLast — accurate internet speed test

CORE METRIC

Download Speed Analyzer

Measures how fast data travels from the internet to your device. Our advanced multi-threaded engine simultaneously opens up to 16 parallel connections, simulating real-world usage like 4K streaming, large file downloads, and web browsing. The result reflects your true maximum throughput without ISP prioritization tricks.

ESSENTIAL FOR CREATORS

Upload Speed Monitor

Critical for video conferencing, cloud backups, live streaming, and sending large files. We measure sustained upload throughput under load, simulating real conditions like Zoom calls or YouTube Live. Our algorithm detects buffer bloat and upload stability across time, not just peak bursts.

Packet loss detection during upload
Latency under load (bufferbloat test)
Optimized for symmetrical fiber & cable

GAMING & VOIP

Ping & Jitter Radar

Latency (ping) measures response time — lower is better for gaming and real-time apps. Jitter tracks latency variation over time, revealing network inconsistency. Our tool sends 50+ ICMP and TCP packets to global servers, delivering a stability score from A+ to F. Detect packet loss, route flapping, and wireless interference.

ADVANCED ANALYTICS

Stability & Bufferbloat Analyzer

Many networks slow down dramatically under load — that's bufferbloat. We simultaneously push download/upload while measuring ping increase. The result shows if your router handles congestion well. Also includes long-duration stability test (1-5 minutes) to detect intermittent drops and ISP throttling patterns.

MOBILE & HOME

Wi-Fi & Cellular Signal Analyzer

Not all speed issues come from your ISP. Our tool measures signal strength, channel congestion, and interference for both 2.4GHz and 5GHz networks. On mobile, it captures 4G/5G signal metrics (RSRP, RSRQ, SNR) to pinpoint if slow speed is due to weak coverage or network saturation.

TRACK PROGRESS

Speed History & Trends Dashboard

One test tells a story; dozens reveal the truth. Our dashboard stores your test history (optional, local or cloud sync) and visualizes performance over days/weeks. Identify peak vs. off-peak hours, track ISP upgrades, and get alerts when speed drops below your baseline. Perfect for remote workers and network admins.
