Fire Horizon is a portfolio tracker built specifically for the FIRE community. Link your brokerage (Plaid/SnapTrade) or import a CSV, and it tracks Coast, Barista, Lean, and Fat FIRE as real plan types, not a retirement-age slider. Get a live net worth, Monte Carlo simulation, dividend income, and withdrawal-strategy modeling, all built on math that's published and auditable. Free to start, no card required, no ads, never sells your data.
