Free tiers we trust

A free tier is a promise about the future: you can build on us before you can pay us. Some companies mean it as a funnel, some as a trial with a hidden clock, and a few mean it structurally — the free tier is priced into how the product works. Only the last kind belongs under a one-person app.

How to read a free tier

• Look for a hard number, not a percent. "10,000 requests a month" is a promise you can plan around. "Fair use" is a promise they can reinterpret. The tools on our list overwhelmingly pick the number.
• Check what happens at the ceiling. The trustworthy pattern is a pause or an email. The untrustworthy pattern is a surprise invoice. You learn this from other people's horror stories before you learn it yourself — search for them first.
• See if the founder plan survived growth. Pull up the pricing page on the Wayback Machine from three years ago. If the free tier shrank every year, you're watching a slow bury in progress — the same pattern that gets tools cut from the list.

Why this matters more at zero revenue

At zero revenue every subscription is a countdown timer on your runway, and worse, a decision tax — five $9 tools is five monthly moments of "is this still worth it?" A generous free tier removes the decision entirely, which is the job. The one bill we always accept early is payments infrastructure: a percentage of something is the only price that's free until it isn't a problem to pay.

The stacks on this site — see the one-person stack — are mostly free tiers plus one or two tools worth real money. That ratio is not stinginess. It's what lets a nights-and-weekends project survive long enough to earn its bills.
