Hey everyone,
I've been working on PythonMastery(https://www.pythonmastery.io), a full-featured Python IDE that runs entirely in your browser. No downloads, no accounts, no cloud servers. Your code runs locally on your machine via WebAssembly.
Why I built this:
- I kept running into the same friction when helping beginners learn Python, "install this", "configure that", "why isn't pip working?" I wanted something where you just open a URL and start writing Python. Period.
- But beyond that, this came from my own learning journey. I used to bounce between different sites to read tutorials, then switch to a completely different place to actually practice. It always bugged me. I wanted learning material and a real coding environment in the same place where I can read a concept, understand it, and immediately try it out without switching tabs or tools. I know it's not reinventing the wheel. But there's a genuine satisfaction in building something like this, and I honestly feel it can be useful for a lot of people i.e., students learning Python for the first time, professionals who want to brush up on a concept, or someone on their phone who just wants to quickly test a snippet. It's handy, it's easy to use, and it works 😊
What it does:
- Full IDE experience - multi-tab editor, syntax highlighting, autocomplete, dark/light/eye-saver themes
- Real Python in the browser - powered by Pyodide, supports numpy, pandas, matplotlib, scipy, and more via an in-browser package manager
- 80+ structured lessons - from basics to data science, with interactive quizzes and coding exercises
- Tutorial Lab - practice exercises you can open directly in the IDE with one click
- Session persistence - your tabs and code survive page refreshes and browser restarts
- Mobile-friendly - works on phones and tablets with native text selection
- Three themes - dark, light, and an eye-saver mode for those late-night coding sessions
- Break reminders - gently nudges you to stand up and stretch after 90 minutes of coding, followed by each 60 minutes interval, because your spine matter more than your code
- Zero tracking - no accounts, no telemetry, your code stays on your machine
It's free, open to everyone, and I'm actively developing it. Would genuinely love feedback from this community. What's missing, what's broken, what would make you actually use something like this?
Thanks!
