[Fillout](https://www.fillout.com) is a hosted, no-code form builder. You build forms with drag-and-drop, then share them as a link on a custom domain or embed them as an iframe, popup, or slider. Fillo renders the form inside your app — your components, your route — and handles validation, uploads, and responses behind it.

## Which should you choose?

### When Fillo fits

- The form belongs inside a signed-in product flow, not on a standalone page or popup.
- Your React or browser components must render the actual fields, on your own route, without an iframe.
- A typed schema should live beside the feature that uses it, shared across client and server validation.
- Uploaded files must go browser-direct to storage you connect — Google Drive, Box, or S3-compatible storage such as Amazon S3 or Cloudflare R2.
- Signed-in account identity should travel with the response.

### When to stay on Fillout

- A hosted, no-code builder is the point: non-technical teammates create and change forms without touching code.
- The form ships as a shareable link, custom-domain page, or embedded popup, and never needs to be native controls on your own route.
- Fillout's AI form generation, themes, and template-driven building are how you want to start, and nothing downstream needs your product's identity or markup.

## Key differences

| Decision | Fillo | Fillout |
| --- | --- | --- |
| Rendered form | Native React or DOM controls, fully headless UI, or a hosted page | Fillout-hosted form shared as a link or loaded through its iframe, popup, slider, and full-screen embeds |
| Authoring | Dashboard or typed `defineForm()` schema | No-code drag-and-drop builder |
| AI | Draft a form with a coding agent through the Fillo skill or MCP server, then own the schema in code | Built-in AI form, quiz, and survey generators inside the Fillout builder |
| Application identity | Optional server-verified respondent ID from your app | Hidden fields and URL parameters |
| File destination | Browser-direct upload to connected Google Drive, Box, or S3-compatible storage such as Amazon S3 or Cloudflare R2 | Files collected and stored through Fillout's service |
| Response limits | Fillo publishes monthly completed-response allowances | Fillout's free plan includes a monthly response allowance, and paid tiers raise it |

Check [Fillo plans and limits](/docs/limits) and [Fillout's current pricing](https://www.fillout.com/pricing) before estimating production volume.

## Before you switch

Fillo doesn't try to be a hosted, no-code builder a non-technical team runs end to end: it has no drag-and-drop hosted-page designer for operators, no AI form generator, no template gallery, and no Fillout importer. If a non-technical team owns the form entirely inside a hosted builder, that workflow changes with Fillo — the form moves into your codebase or the Fillo editor. Fillo also starts a new response history: a Fillout CSV or file export stays an external record and can't be imported as Fillo responses with versions and delivery state.

## What you would need to change

| Existing Fillout form | Expected work |
| --- | --- |
| A shared link or iframe/popup embed | Rebuild the fields and pages in Fillo, publish, and render them on your route or a hosted page |
| Hidden fields, logic, uploads, and integrations | Map each setting to stable field IDs, connect storage, and test every branch and destination |
| AI-generated starting points, custom domains, or hosted-page themes | Rebuild in Fillo's schema and update downstream consumers before cutover |

## Next step

[Open the editor](/new) and rebuild one real form first. If it belongs inside your product, read [Embed a Fillo form](/docs/embed) for the native React, DOM, and hosted options.
