Radar Fiscal CodeUtil.devRadar Fiscal's answer
It's the only tool that shows personalized tax deadlines for Spanish autรณnomos โ filtered by your exact tax regime. Not a generic calendar, not a gestorรญa trying to sell you services. Just your deadlines, at a glance.
CodeUtil.dev's answer:
CodeUtil.dev runs entirely in the browser โ all processing happens on your device, so your data never touches a server. It bundles 20+ tools (JSON, regex, Base64, JWT, cron, hashing, and more) under one roof with zero sign-up. Just open the page and start working.
Radar Fiscal's answer
Competitors are accounting SaaS platforms that happen to have blog articles about deadlines. Radar Fiscal is purpose-built for one thing: knowing what you owe and when. It's free, works as a browser extension, supports 9 languages for expats, and syncs with your calendar app.
Radar Fiscal's answer
Self-employed workers (autรณnomos) in Spain, especially expats who aren't yet familiar with the Spanish tax system. Also useful for any autรณnomo who wants a quick visual overview of upcoming deadlines without navigating the AEAT website.
Radar Fiscal's answer
I moved to Spain and became autรณnomo. The AEAT calendar lists every obligation for every taxpayer โ overwhelming when you just want to know what applies to you. I built Radar Fiscal to solve my own problem: a simple tool that tells you "here's what YOU need to file, and here's the date."

TypeScript, Lit (web components), Vite, Cloudflare Workers. Chrome Extension (Manifest V3) and Firefox add-on.
