Show HN: How long do I need to work at my salary before I can coast, or retire?

A developer created "fire," a day-by-day financial simulator that calculates how long someone needs to work at a high salary before they can coast, retire, or retire without depleting their nest egg by age 112. The tool models daily income (after taxes), expenses (with a safety buffer), and investments to determine the exact stop date for various retirement goals, and includes features like geographic moves, tax-advantaged accounts, and what-if scenarios. The creator notes it's a "vibe-coded" tool built with AI assistance and not professional financial advice, meant for exploring retirement planning ideas.
