Typero: A Distraction-Free Typing Speed Test

Why I Built It

I type a lot. And I kept running into the same problem — every typing test out there is either full of ads, wants your email, or has so much going on that it becomes a distraction in itself. I also wanted to practice with my own files — domain-specific text, complex words I kept mistyping — not just random word lists.

So I built Typero for myself. A clean, focused typing test with no ads, no sign-up required, and the ability to import your own .txt files.

Then I thought — why keep it to myself? So I opened it up.

What It Does

• Timed and open-ended typing modes
• Strict mode (must fix every error) and Forgiving mode
• Import your own .txt files for domain-specific practice
• Live WPM, CPM, and accuracy tracking
• Per-session performance graph
• Activity heatmap and streak tracking (logged-in users)
• Sound feedback on keystrokes
• Zen mode — hide all stats while typing
• No ads, no email required, no tracking

How to Use It

1. Go to https://typero.app
2. Pick your mode — Timed (30s, 60s, 120s, 180s) or Open
3. Choose Forgiving or Strict mistake handling
4. Optionally import a .txt file under Import .txt for your own text
5. Hit Start Typing and go
6. Results page shows your WPM, accuracy, peak WPM, and what to improve
7. Create an account to track your history, streak, and activity heatmap

How I Built It

Fully vibecoded using Claude Code (Opus & Sonnet). No traditional dev process — just ideas turned into prompts turned into a working product. The entire thing from concept to deployment happened in a single focused session.

The stack is deliberately minimal:

• Node.js + Express for the backend
• SQLite for storage — no external DB
• Vanilla JS on the frontend — no frameworks, no build step
• JWT + bcrypt for auth, HTTP-only cookies
• Deployed on AWS EC2 with Nginx + Cloudflare in front

What I Learned

• SQLite is genuinely underrated for small tools — zero config, fast, and just works
• Vibecoding with Claude Code is surprisingly capable for production-quality output
• Cloudflare adds a surprising amount of value for free (CDN, DDoS, SSL)
• The hardest part of building a typing test is getting the WPM math right

What’s Next

• Mobile-friendly read-only results page
• More detailed per-key heatmap
• Custom word lists and categories
