Google Forms' winning side is clear: free, you already have an account, a survey is up in five minutes. But push a bit further and you hit a wall — no conditional logic, no payments, limited branding. Fillout is also free but goes past those walls. Short answer: Google Forms for a one-off simple survey, Fillout for everything else.
The details below come from Fillout's own pages and independent comparisons; all sourced. I'm a Fillout affiliate, but I name clearly where Google Forms is enough.
When Google Forms is enough
Let's be fair: if you need a simple survey or a quick registration form, you don't care about branding, and dumping results into a Sheet is enough, Google Forms does the job perfectly. Zero learning curve, everyone has an account, instant to share. For that, switching tools is overkill.
When Fillout wins
Once the job gets a bit more serious, Fillout pulls ahead: conditional logic (forms that branch on answers), taking payments through the form, on-brand design and a custom domain, white-label, and bidirectional work with Airtable/Notion. And most of that is on the free plan — up to 1,000 responses a month. So for application forms, paid registrations, multi-step quizzes, where Google Forms falls short, Fillout takes over.
| Fillout | Google Forms | |
|---|---|---|
| Conditional logic | Yes (free) | Very limited |
| Take payments | Yes | No |
| Branding / custom domain | Yes | Limited |
| Strongest at | Powerful, flexible forms | Speed + zero setup |
