## What it is
Blip is a browser-based tool that visualizes Internet latency in real time by plotting ping times as blips on a graph. It runs on any device with JavaScript and HTML canvas support, measuring round-trip times and packet loss at up to 100 samples per second.

## Use cases
- measure my internet latency in the browser
- diagnose wifi network quality and packet loss
- see how latency changes when streaming video or switching networks
- compare ping times to nearby vs distant servers
- troubleshoot brief network outages that ping misses
- check if my internet connection has low latency without installing software

## When to avoid
- you need deep packet inspection or bandwidth/speed testing rather than latency
- you require long-term historical monitoring with alerting and dashboards
- you need to measure latency to arbitrary custom hosts

## Facets
- artifact type: application
- maturity: maintenance
- function: monitoring, analytics, data-visualization
- domain: networking, developer-tools, performance
- platform: browser, cross-platform
- tags: latency-measurement, ping, network-diagnostics, javascript, browser-based, web-server
