DevTrials
Code it. Run it. Own it.
Interactive programming lessons with a live terminal built right in. No local setup, no copy-pasting into a separate window — just read the exercise, type the commands, and see it work.
Learning tracks
Four tracks, each self-contained. Pick one or do all of them.
Python
General programming, data science, and AI
The most beginner-friendly language and the #1 choice for AI and data science. Readable syntax, huge ecosystem, and a clear path from beginner to professional.
Bash
Shell scripting and automation
Turn repetitive terminal tasks into one-line commands. Automate deployments, manage files in bulk, and build the glue that holds your infrastructure together.
Go
Fast backend and systems programming
Compiled, statically typed, and dead simple. Powers Docker, Kubernetes, and Terraform. Ships as a single binary with no runtime needed.
RAG & Offline AI
Build your own private AI with Ollama
Build a Retrieval-Augmented Generation pipeline that runs 100% locally — no API keys, no cloud, no data leaving your machine.
How it works
Live terminal in the browser
Every lesson has a real bash shell. You type commands and see actual output — not simulated, not sandboxed animations.
Progressive difficulty
Each track goes Fundamentals → Basic → Medium → Hard → Final Project. Start from zero or jump to where you need.
Hints when you're stuck
Every exercise has three levels of hints, from a nudge to a full solution. Learn at your own pace without getting frustrated.
100% offline
The RAG track runs entirely on your machine with Ollama and ChromaDB. No data leaves your network.
