How we picked
Every tool here is published on Toolradar with an editorial score of 74 or above, out of 145 tracked in this category. Ordering follows that score, then third-party review volume, so a tool with one glowing review does not outrank one with a thousand. The figures update as the catalog does.
FAQ
How many app builders tools are there?
We track 145 published app builders tools, of which 49 clear our editorial bar. 119 were added during 2026, which reflects when we indexed them rather than when each vendor launched.
Are there free app builders tools?
Yes, and they dominate: 97 of 145 offer a free tier, 67%. Free usually means a usage cap rather than a feature cap, so the ceiling arrives with volume.
How should I shortlist?
Start from the constraint that will not move: budget, an existing stack you must integrate with, or a compliance requirement. Filter on that first, then compare the two or three that survive. Ranking by feature count leads to the most expensive tool every time.
