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.

Features

For learners

Area	What you get
SQL cases	100+ real-world cases across 9 domains (finance, healthcare, space, etc.)
Data-science projects	38 guided projects in 9 domains (transport, churn, fraud, ESG, more)
Cloud missions	AWS/Azure/GCP/ESG/FinOps tracks — quizzes, scenarios, build missions, checklist
Interactive editors	CodeMirror with syntax highlighting, autocomplete, keyboard shortcuts
Live execution	sql.js for SQL, Pyodide for Python, client-side AWS simulator — all browser
The Arena	Coach or tag-team duels vs the house bot; daily duel, rival ladder, replays
Smart error help	Contextual hints + checkers that say why a result is wrong
Visualizations	Auto-charts (Plotly) for completed cases; Python/R viz guides in Lab
Hints & solutions	Progressive hints (first 3 free), thought-process walkthroughs, full solutions
Points & shop	Earn points for solving; spend on skips, trial unlocks, cosmetic titles
Quizzes	Per-topic quizzes for SQL trials, Lab, and Cloud
Test mode	Optional timed challenges with tier-based limits
GitHub export	Push solved work to your own portfolio repo with one click
Cross-device sync	Sign in with GitHub → progress syncs via Supabase
Mobile-friendly	Wrapping toolbars, sticky Run — works on phones

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.
