Technical Documentation
Does ToolNova store my code?
No. All developer tools, including the HTML Editor and JSON Formatter, process data locally using WebAssembly and Javascript.
Can I test local APIs with the REST Client?
Yes, since the tool runs in your browser, it can reach localhost and internal network endpoints that cloud-based testers cannot.
Are the QR codes generated in vector format?
Yes, the QR Architect allows for high-fidelity SVG exports suitable for professional print and digital branding.
