About Blog.Kriativity
Blog.Kriativity is a free, interactive learning platform built for developers who learn by doing. Every course is designed around real exercises you can run directly in your browser no environment setup, no login required.
Our Mission
High-quality technical education should be free and accessible. Too many developers are locked out of good learning resources by paywalls, slow videos, or environments that take an hour to set up before you can write a single line of code.
We build courses that get you writing and running real code in under a minute. Progress is tracked locally in your browser no account, no tracking, no friction.
How the Platform Works
Read structured content
Each topic has a clear introduction, key points, annotated code examples, common mistakes, and PostgreSQL-specific callouts.
Practice in the browser
SQL exercises run in a real PostgreSQL instance powered by PGLite a WebAssembly build of Postgres that runs entirely client-side. No server, no installation.
Test your knowledge
Multiple-choice quizzes after each topic give you instant feedback and explanations. Your progress is saved in your browser's localStorage automatically.
