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

01

Route people down different paths, skip irrelevant questions, and call any API mid-flow — connect the steps on a canvas and the logic just runs.

Reuse 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.
