I Built DevSheets.io - A Modern Cheat Sheet Site for Developers (And Why We Still Need Them)

Brad Traversy — Mon, 13 Oct 2025 11:37:53 +0000

We've all been there. You're deep in a coding session, need to remember that one Git command, or the syntax for a CSS flexbox property. You Google it, click the first result, and... ads everywhere. Outdated information. Slow loading. Ten paragraphs before getting to the actual answer.

That's why I built DevSheets.io - a modern, fast, and clean cheat sheet platform designed the way developers actually work.

The Problem with Existing Cheat Sheets

Don't get me wrong - there are some great resources out there. But many suffer from:

Information overload without structure - Everything on one massive scrollable page
Outdated content - Still showing jQuery examples in 2025
Terrible UX - Intrusive ads, slow loading, poor mobile experience
No search - Finding specific commands means Ctrl+F through walls of text

I wanted something that felt native to how we actually code - quick, focused, and just works. I have been creating educational content on web dev and other tech topics for years and I have taken the stuff that people often struggle with, and put it into short, concise sheets that are easy to understand.

It does not cost a dime and there are not even any advertisements. It is completely free to view all 50+ sheets.

What Makes DevSheets Different

1. Clean, Focused Design

Each cheat sheet is organized logically with a clear table of contents. No distractions, no ads. Just the information you need.

2. Modern Tech Coverage

We focus on technologies developers actually use in 2025:

React Router v7 (with the new Library and Framework modes)
TanStack Query for server state management
Docker commands and orchestration
Modern JavaScript patterns (async/await, modules, etc.)

3. Estimated Read Time & Difficulty

Every sheet shows how long it'll take to reference and the complexity level. Planning to learn TypeScript? You'll know it's a 10-minute intermediate-level reference before you dive in.

4. Built for Speed

The entire site is optimized for performance. No bloat, instant navigation, works great on mobile when you're pair programming and need a quick reference.

The Stack

For the tech-curious, here's what powers DevSheets:

Frontend: React 19, Next.js 15, TypeScript
Backend & DB - Next.js, Prisma, PostgreSQL (Neon)
Styling: Clean, responsive CSS with Tailwind CSS
DevOps - Vercel, Github Actions
Content: Structured data that's easy to update and maintain
Icons: Custom SVG icons for each technology as well as Heroicons

I'm also considering:

Dark mode toggle (because of course)
Downloadable PDFs for offline reference
Community contributions for niche technologies
Interactive examples for certain concepts

Why I'm Sharing This

I built DevSheets because I needed it myself. The best tools often come from scratching your own itch.

But here's the thing - I want your feedback. What cheat sheets are you missing? What could be better organized? What technologies should I add next?

Check it out at devsheets.io and let me know what you think in the comments.

For Fellow Builders

If you're thinking about creating a developer tool or resource:

Start with your own pain point - If you need it, others probably do too
Keep it simple - Don't over-engineer v1
Make it fast - Developers have zero patience for slow sites
Get feedback early - Build in public, share often

The web is full of resources, but there's always room for something done better, faster, or with more care for the user experience.
