TinyTools Lab publishes small, single-purpose calculators for Dutch personal finance. No signup, no tracking, no bloat; every tool is a static page on the permaweb so it stays online.
Current tools: WWS rent-subsidy estimate, Box 3 wealth-tax check, rent-increase calculator, solar-panel payback check and a stablecoin yield scan.
All tools, guides and the two-page catalog live here:
