10 Free Developer Tools I Actually Use Every Day (No Signup, No BS)
As developers, we constantly need small utilities — format some JSON, decode a JWT, generate a UUID, compress a screenshot before uploading. Most of us either Google around, install a random VS Code extension, or paste sensitive data into some sketchy ad-filled site. Over the past few months, I've been building Dev Hacks — a collection of 100+ free tools that run entirely in the browser. No…
Developers often require quick utilities to format JSON, decode JWTs, generate UUIDs, compress images, create QR codes, format SQL queries, convert markdown to HTML, count words, and minify JSON. However, many developers rely on random VS Code extensions or sketchy websites that may expose sensitive data. To address this issue, the author has developed a collection of 100+ free, browser-based tools that require no signup and keep data private. The 10 tools they use most frequently include:
1. JSON Beautifier & Validator
2. JWT Decoder
3. UUID Generator
4. Image Compressor
5. Image Converter
6. QR Code Generator
7. SQL Formatter
8. Markdown to HTML
9. Word Counter
10. JSON Minifier
All of these tools run entirely in the browser, using JavaScript, ensuring that API keys, tokens, and other sensitive data remain on the user's machine. The collection is available at devhacks.tech, with more tools being added weekly based on user requests.
