Interactive simulators

See for yourself how technical decisions shape the cost, speed and reliability of a digital product. Move a slider and watch what happens.

Business & costs

• Project cost estimator: Pick the type, pages and features: get a price range and a timeline.
• New website ROI: What a faster, clearer site earns and how many months it takes to pay back.

Performance & infrastructure

• Page speed (Core Web Vitals): Images, JavaScript, CDN, caching: watch LCP, CLS and the score change.
• Traffic & server scaling: How many servers you need at peak traffic and what autoscaling costs.
• Uptime & SLA: Compose an architecture and find out how many minutes a year it may be down.
• Cache policies (LRU, LFU, FIFO): Watch step by step what stays in the cache and what gets evicted.

Web & UX

• Responsive design: Drag the width and watch a page rearrange on phone, tablet and desktop.

Algorithms

• Sorting algorithms: Bubble, insertion, merge, quick and heap sort, animated step by step.
• Pathfinding (A*, Dijkstra): Draw walls and rough terrain, then watch the algorithms find a way.
