Fillout alternative for forms inside your product
Compare Fillout with Fillo when a hosted no-code form moves into your product: native controls on your own route and one schema shared across validation, uploads, and responses.
When a hosted builder meets your product
Fillout is a no-code builder for hosted forms. Fillo is for the point where the form has to render inside your app, with your components, signed-in context, and your own storage.
One schema, every surface.
Stable field IDs carry from the rendered form through server checks, the response grid, and exports.
The answer arrives with its context.
See what someone sent, which account it came from, and where in your app they were.
Files land in storage you own.
Uploads go browser-direct to connected Google Drive, Box, or S3-compatible storage, and stay attached to the response.
Fillout 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 and Fillout's current 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 and rebuild one real form first. If it belongs inside your product, read Embed a Fillo form for the native React, DOM, and hosted options.
