Happy New Year, everyone! 🎉
I hope 2026 is off to a great start for all of you. To kick off the year, I’ve been working on a massive update for my side project, CodeCoffeeTools.
A few weeks ago, I shared CodeCoffeeTools here a collection of developer tools + ... that run 100% locally in your browser. The response was amazing, but I kept hearing one request
How do I move these secure files between my devices without using the cloud?
So, I got to work. ☕
I just pushed a major update to CodeCoffeeTools, introducing Peer-to-Peer (P2P) File Transfer, a native App Install (PWA) feature, and a bunch of new utilities.
Here is what’s new! 👇
1. P2P File Transfer (No Server Storage)
We've all been there: You have a sensitive file on your laptop that you need on your phone. You usually email it to yourself or upload it to a random cloud drive. That breaks the privacy chain.
I added a new P2P File Transfer tool that connects your devices directly.
- How it works: It establishes a direct connection between your browser tabs (using WebRTC logic).
- Privacy: The file streams strictly from Device A to Device B. It is never stored on my server, not even for a second.
- Speed: Since it's local (if you are on the same WiFi), it's blazing fast.
2. You Can Now "Install" The App
CodeCoffeeTools is now a fully capable Progressive Web App (PWA).
-
Install it: Click the "Install" button (or the
+icon in your address bar) to add it to your Dock (Mac) or Home Screen (iOS/Android). - Offline Capable: Many tools now work even if you lose your internet connection.
- Native Feel: No more hunting through browser tabs to find your JSON validator.
3. Freshly Brewed Tools
I didn't stop at infrastructure. Based on your feedback, I’ve added several new tools to the roster:
- SVG to PNG Converter: Scale and convert vectors without pixelation.
- QR Code Generator: Create quick links for testing on mobile devices.
- Citation Generator: (For the students out there!) Format references instantly.
- Cooking & Unit Converters: Because sometimes developers bake too. 🍰
Why "Privacy-First" Still Matters
Every tool on the site still adheres to the core philosophy: Your data never leaves your device. whether you are compressing a massive image or formatting a sensitive SQL query, the processing happens in your browser's JavaScript engine, not on a backend server.
Try It Out
I’m building this as I complete my software engineering degree, and I’d love your feedback on the new P2P feature.
