Boldin is a planning tool first. You describe your situation in detail and it models the consequences — taxes, conversions, claiming ages — with more depth than anything else at consumer pricing. Fire Horizon starts from the other end: it holds your actual portfolio, prices it daily, and answers whether the plan still works given what your accounts did this week. Both are legitimate; they answer different questions.
A 45-year retirement is not a 25-year retirement with different numbers. Sequence-of-returns risk matters more, Social Security arrives decades late, and the FIRE variants are real strategies rather than labels — Coast means deliberately stopping contributions at a chosen age and letting compounding finish the job, which needs two markers on the chart, not one. That is the part built into Fire Horizon and approximated everywhere else.
If you are within a decade of a traditional retirement and weighing Roth conversions against future tax brackets, Boldin is the better tool and we do not model that at all. Their free tier is enough to see whether that depth is what you need.

Both have real free tiers, so the honest way to decide is to run your own numbers through each. Ours takes a few minutes to set up — free, no card required.
