How TinyURL Works? Explained by Monkey
A humorous animated explainer on URL shortener system design: short links, redirects, databases, caching, and scaling when a tiny link becomes very popular.

How TinyURL Works? Explained by Monkey
This is my animated, slightly unserious take on URL shortener system design.
The written URL shortener article is the careful engineering version. This video is the visual version: faster, funnier, and built for people who want the idea to click before they dive into the deeper tradeoffs.
What the video covers
- Why URL shorteners exist
- How a long URL becomes a short code
- What happens when someone opens a short link
- Why the database is the source of truth
- Where caching helps when a link gets popular
- How the system grows without making the first version too dramatic
