I built MyDepreciation after getting frustrated with TurboTax paywalling basic MACRS calculations ($80 for the "Self-Employed" tier).

*Technical details:*

• Vanilla JS, no frameworks (wanted to keep it lightweight) • 100% client-side (no backend, no analytics, no data collection) • MACRS tables hardcoded from IRS Publication 946 (public domain) • Total bundle size: 3KB gzipped • Hosted on Cloudflare Pages (free tier)

*Why no framework?* The entire app is just form inputs + table lookups + arithmetic. Adding React/Vue would 10x the bundle size for zero benefit.

*Privacy-first design:* Your financial data never leaves your browser. No cookies, no tracking, no "sign up to save calculations." Just pure math.

*Why free?* The MACRS tables are published by the IRS for free. Paywalling them felt like gatekeeping public information. Plus, hosting costs $0 (static site), so there's no pressure to monetize.

*Open to feedback, especially:* • Bugs in calculations (I'm not a CPA—if you spot errors, please flag) • UX improvements (I'm an engineer, not a designer) • Edge cases I missed (depreciation has a LOT of gotchas)

Happy to answer questions!17:T514,AI shopping agents are coming. ChatGPT, Gemini, and Perplexity are learning to browse and buy from online stores. But most stores aren't set up to be discovered.

UCP (Universal Commerce Protocol) is the new open standard by Google & Shopify that makes stores readable by AI agents - like robots.txt for AI commerce.

We built UCPtools to help merchants get ready for AI commerce:

FREE TOOLS (no signup): • UCP Validator - check your profile in seconds • AI Agent Simulator - see how agents interact with your store • Security Scanner -
