Show HN: Prism.Tools – Now 100% Offline capable
I've completely overhauled Prism.Tools to be 100% offline-capable and privacy-focused, with significant tool improvements.
WHAT CHANGED?
- Dependencies: Moved from external CDN libraries to LOCAL libraries only (/lib folder)
- Privacy: Zero external requests now (no potential CDN tracking)
- Offline Use: Works completely offline after download (no internet required)
- Licenses: All licenses included (/lib/license/)
- Assets: Local Web Safe fonts (/tools/fonts/)
TOOL UPDATES:
1. ASCII Art Generator:
- Improved performance using FIGlet.js
Credit: Created by Glenn Chappell and other FIGlet contributors
- Animate button cycles through all fonts for quick review
2. SVG Editor:
- Completely reworked with expanded capabilities
- Educational design with help tooltips
- Professional features (transform engine, gradients, group

ing)
- Beginner-friendly with default example to explore features
3. Other Updated Tools:
- Code Formatter, Diff Checker, Hash Generator, SQL Formatter, YAML/JSON Converter, QR Code Generator

TESTING OFFLINE FUNCTIONALITY:
1. Download complete repository
2. Disconnect from internet
3. Open index.html in browser
4. Test all tools - should work normally
TIP: Use Chrome's "Application" tab in Developer Tools to verify no network requests are made.
Q: Why these changes?
A: To ensure privacy and provide reliable, always-available tools regardless of internet connectivity.
Q: What if I don't update?
A: Old versions will eventually break when CDNs change or shut down. They also send data to third parties.
