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 Outdated information.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- Outdated content - Still showing jQuery examples in 2025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.
