Bleepx — Learn SQL, Data Science & Cloud by Solving Cases
Bleepx is a browser-native learning platform where you master SQL (BleepxQuery), Python/R data science (BleepxLab), and cloud architecture (BleepxCloud) by solving realistic case studies. Everything runs client-side on WebAssembly — your code never leaves your device. And when you want a fight, the Bleepx Arena pits your champion against the house bot in real-code duels.

What is Bleepx?
Bleepx turns "another SQL tutorial" into narrative case studies you actually want to finish. Each case drops you into a believable scenario — a missing-data investigation, a supply-chain mystery, a telecom-churn prediction, an S3 misconfiguration — and hands you the tools to crack it.
Why it's different:
- Built-in guide, Bleepx — a pixelated mascot who gives hints, reacts to mistakes, and celebrates wins with bleepy commentary.
- Zero setup, zero wall — SQL runs via
sql.js, Python runs via Pyodide, cloud missions run in a client-side simulator. Browse and run everything as a guest; sign-in is only asked when you want progress saved.
- The Arena — coach a champion through real-code duels (live SQL execution, Pyodide duels, sandbox build missions), or tag in and fight the last round yourself. Shareable match cards + replays.
- Progression with teeth — points, streaks, achievements, a shop, a daily duel, a rival ladder, champion evolution bridged from training.
- Portfolio-ready — one click pushes your solved work to a GitHub repo (
sql-portfolio, ds-portfolio).
- Honest pricing — everything is free today; Bleepx Verified is labeled a free preview until real checkout lands.

For admins
- Anonymous PostHog analytics — which cases are popular, where users drop off.
- Save-time sign-in gate — guests run everything; GitHub sign-in is asked at completion (progress, points, portfolio push).
- Supabase daily keep-alive — GitHub Actions cron prevents free-tier pause.
- Security overrides — pnpm/npm overrides pin patched versions of flagged CVEs.
- YAML-driven curriculum — add a case by dropping a
.yaml file. No code changes needed.
