Coding practice drills
Card-based, self-contained drills across JavaScript, TypeScript, HTML, Node.js, and Node microservices. Each drill has a question, expected output, starter code, hidden tests, layered hints, a reference solution, and complexity notes — run in your browser.
AI / peer / mentor mock interviews
Timed mock interview sessions led by an AI interviewer (powered by Google Gemini free tier), by a peer, or by a mentor. Optional recording, structured feedback, and per-session scoring.
Peer code reviews
Request reviews on your solutions and review others’. Inline comments, a review queue, reputation, and a thanks system — learn by reading and critiquing real code.
Progress analytics
A personal dashboard with D3 visualisations: streaks, milestones, per-track completion, and a PDF export of your progress you can share with a recruiter or mentor.
50+ developer tools
Fully client-side utilities: PDF-to-Word, image compression, hash and UUID generators, QR codes, JSON/CSV/XML converters, JWT decoder, colour tools, and more — nothing is uploaded.
Free, private, and cross-platform
A generous free tier on a zero-cost architecture. Sign in with Google, run it as a Progressive Web App, or install the Android app. Your code runs locally for privacy.
