SHADER7 was founded in 2023 by me, Nishikant Xalxo, after 5 years of working as a FANUC CNC milling machine operator. The frustration was real: every useful online tool either required registration, forced you into a "free trial" that asked for credit cards, or bombarded you with ads that compromised privacy.
Working daily with FANUC 0i-MF controls on vertical mills, I needed quick, reliable tools for G-code reference, feed rate calculations, and document creation. When I needed a passport photo for a work visa to Germany, I found every "free" tool demanded my email. That's when I decided to build my own.
Why "Free Forever" Actually Means Free
Unlike freemium tools that limit features, SHADER7 provides full functionality without paywalls. Here's how we sustain operations:
Voluntary Donations: Users who find value can contribute via Stripe (we never see payment details)
Privacy-Focused Ads: Google AdSense displays relevant ads without tracking users
Minimal Overhead: Tools run client-side, reducing server costs by 80%
Privacy-First Architecture
All tool processing happens directly in your browser using JavaScript. When you upload a photo for passport editing or enter salary data, it NEVER leaves your device. Close the tab and your data is permanently gone from memory.
