ByteByteGo System Design Newsletter
Short, heavily illustrated explanations of how real systems work, published regularly. The diagrams are the point, and they are the fastest way to build intuition for architectures you have never seen.

What it is
A newsletter and blog covering one system design concept or real world architecture at a time, built around clear diagrams rather than long prose.
Why the format works
System design is spatial. A diagram that shows where the cache sits relative to the database and the queue conveys in five seconds what four paragraphs struggle with. Reading one of these a week builds a mental library of architectures you can draw on later.
How to use it
Subscribe and read casually. This is background accumulation, not a study plan. It works best alongside structured material rather than in place of it, because a stream of interesting diagrams never adds up to a curriculum.
Best for: ongoing learning for working engineers, and light revision during preparation.

Stuck on something specific?
Writing only gets you so far. If you want an answer to your situation rather than the general case, book a session and we will work through it together. Every session is free; a few slots open each week.
