As a developer, I often find myself opening multiple websites — or prompting AI tools - just to get small things done.
Decode a JWT. Generate a UUID. Convert a timestamp. Test a regex.
All tiny tasks that somehow end up wasting time.
And the biggest concern? Data insecurity.
I never felt comfortable pasting tokens or keys into random online tools.
So, I decided to build something simple, fast, and private.
DevTills
🔒 Why DevTills?
DevTills is a privacy-focused collection of everyday developer tools, built to run entirely in your browser.
No servers, no signups, no tracking of your input data just local execution.
I do use Firebase Analytics to track anonymous tool usage (e.g., which tool was opened),
but no sensitive data is ever logged, stored, or sent anywhere.
⚙️ Tools Included (So Far)
🔑 Base64 Encoder / Decoder
🕒 Timestamp Converter
🧩 Regex Tester
🆔 UUID Generator
🎨 Color Picker
🔍 Text Diff Tool
🔐 Password Generator
🧮 Box Shadow & Gradient Generator
🖼️ Image → Base64 Converter
🔢 Hash Generator
🔐 JWT Decoder
...and many more
💡 Why I Built It
I built DevTills out of frustration, constantly jumping between sites and worrying about data security.
Now I use it daily myself, and it’s made my workflow so much smoother.
If you often find yourself searching “best online tool for ___,”
DevTills might just save you a few tabs 😅
