Technical Simple publishes short, practical tutorials on the tools developers are adopting right now. Every article is written to be read in a few minutes and used straight away: a clear explanation, working code, and the mistakes to avoid.
What we cover
- AI & Machine Learning - calling LLM APIs, prompting, retrieval-augmented generation, AI agents and the Model Context Protocol.
- Web Development - React, Next.js, TypeScript, modern CSS, Node.js, FastAPI and API design.
- Programming Languages - Rust, Go, modern JavaScript and Python.
- Cloud & DevOps - Docker, Kubernetes, Git, GitHub Actions, Terraform and observability.
- Databases - PostgreSQL, MySQL, Redis and MongoDB.
- Security - the OWASP Top 10 and modern authentication.
- Interview Questions - JavaScript, React, SQL and system design, with flashcards to practise.
How we write
- Code first. Examples are complete enough to copy and run.
- One idea per article. Each post answers one question well instead of ten questions badly.
- Kept current. Topics are chosen from what teams are adopting today, and articles are updated when tools change.
Free developer tools
Alongside the articles you'll find small browser tools we use ourselves: a JSON formatter, JWT decoder, regex tester, cron helper, Base64 and hash generators, a case converter and an HTML editor. They run in your browser, so nothing you paste is sent to our server.
