shur.click - URL Shortener
shur.click is a production-ready URL shortener that creates compact links and delivers ultra-fast redirects with analytics and secure link management.
Technology Stack
Key Challenges
- • Generating unique short codes with collision resistance
- • Designing Redis caching strategy for O(1) redirect lookups
- • Separating analytics write path from redirect read path
- • Handling concurrent link creation safely
- • Preventing abuse using validation and rate limiting
- • Managing link expiration and soft deletion logic
Key Learnings
- • Designing high-read, low-latency systems
- • Cache aside pattern with Redis + persistent database
- • Building scalable redirect flows without blocking threads
- • Structuring clean API layers for frontend integration
- • Understanding tradeoffs between memory speed and durability
- • Applying defensive backend design for public APIs
Overview
shur.click is a high-performance URL shortening platform focused on fast redirects, reliability, and clean link management. It lets users create compact links, manage them from a dashboard, and monitor click activity in a simple workflow.
The platform is designed so redirects stay consistently fast while analytics are tracked in the background, keeping the user experience smooth and production-ready.
What It Can Do
- Generate Short Links with collision safe unique codes
- Instant Redirects powered by Redis for ultra low latency lookups
- Link Expiry Control to automatically disable links after a set time
- Click Analytics Tracking without slowing down redirect performance
- Secure API Design with validation and abuse prevention
- Dashboard Management to create, monitor, and manage links
Why I Built This
I wanted to understand how real world high read systems are designed. A URL shortener looks simple, but it hides interesting system design challenges like collision handling, caching strategy, redirect speed, and analytics separation.
This project helped me explore:
- Cache aside architecture using Redis and a persistent database
- Designing extremely fast read paths for redirects
- Handling concurrent link creation safely
- Building scalable public APIs with rate limiting
- Creating clean contracts between backend and a TypeScript frontend
shur.click is not just about shortening URLs. It is about understanding how performance, reliability, and simplicity come together in backend engineering.
