What’s your team size?
Why Fillu
Most form tools stop at collecting answers.
Fillu forms react. Branch on what people say, personalize the next step, and call your own systems — all from a visual canvas, no engineer required.
Branch on every answer
01Route people down different paths, skip irrelevant questions, and call any API mid-flow — connect the steps on a canvas and the logic just runs.
Welcome, {{ contact.name }}
Personalize in real time
02Reuse earlier answers anywhere. Greet people by name, pre-fill fields, and show the right options based on what they've already told you.

Questions, answered
- Do I need to know how to code?
- No. You design the whole flow visually — pages, questions, logic, and integrations — by connecting steps on a canvas. No code, no developers.
- Is it really free to start?
- Yes. You can build and publish a form without signing up or entering a card. There is a free plan, and you only pay when you need more.
- Can forms connect to my other tools?
- Yes. A form can call any API mid-flow — push answers to your CRM, look up data, or trigger a workflow — using the HTTP step, no glue code required.
- How do people fill out the form?
- Hit Publish and you get a shareable link. Respondents open it in any browser and move through your steps one at a time — nothing to install.
