Tally is a hosted builder with a famously generous free plan — unlimited forms and submissions within its fair-use policy. You share its forms as a link, popup, or iframe. Fillo picks up where that model stops: when the form has to be part of your product rather than a page you link to.

Which should you choose?

When Fillo fits

The form has to render as native controls inside an existing product route.
Your component system should own layout, focus behavior, and field rendering.
The schema belongs in code, or needs to be shared across rendering, validation, responses, and exports.
Signed-in account identity should travel with the response.
Uploaded files must go directly to Google Drive, Box, or S3-compatible storage such as Amazon S3 or Cloudflare R2 that you connect.

When to stay on Tally

The form never touches your product — a hosted link or popup does the job.
It depends on Tally's payments, custom domains, or non-numeric calculations. Fillo doesn't have those today — its calculated fields handle numbers only.
Nobody on the team is going to touch code for this form, and the current integrations already work.

Where the free plan stops

Tally's free tier really does include the builder features. The lines you'll actually hit are on its pricing page (as of August 2026):

Uploads are capped at 10 MB per file on the free plan; removing the limit is a Pro feature. Fillo uploads go browser-direct to storage you connect — Google Drive, Box, or S3-compatible — up to 5 GB per file, on either plan.
Partial submissions are a Pro feature. On free, an abandoned form is just gone. Fillo saves and resumes drafts on every plan, and partial entries never count against your response limit — only completed responses do.
A custom domain is a Pro feature. With Fillo the question doesn't come up for product forms: the form renders on your route, in your app, as your components.

None of that is a complaint about Tally's pricing — a free tier this generous has to draw lines somewhere. It's a map of where "free and hosted" ends and "part of your product" begins.

Key differences

Decision	Fillo	Tally
Rendered form	Native React or DOM controls, fully headless UI, or a hosted page	Tally-hosted form in standard, popup, or full-page embeds
Authoring	Dashboard or typed `defineForm()` schema	Document-style visual builder
Application identity	Optional server-verified respondent ID from your app	Hidden values and Tally's duplicate-submission controls
File destination	Browser-direct upload to storage connected by your workspace	Files collected and managed through Tally's service and plan rules
Calculations	Numeric calculated fields: totals and derived values, recomputed on the server	Calculations are a documented Tally feature
Payments	No payment field today	Payment collection is a documented Tally feature
Pricing shape	Fillo plans limit completed responses; renderer access is included on both plans	Tally advertises unlimited forms and submissions within its fair-use policy

Check Fillo plans and limits and Tally's current pricing before comparing costs for a live form.

What you would need to change

Existing Tally form	Expected work
Questions, required fields, and a single completion screen	Rebuild the fields, publish, and replace the link or embed
Pages, hidden values, logic, numeric calculations, uploads, and destinations	Map each rule and setting, rebuild calculations as calculated fields, connect storage, and test every path
Payments, custom code, non-numeric calculations, or automations built around Tally payloads	Redesign those parts and update downstream consumers before cutover

Old Tally submissions don't become Fillo responses. Export them and keep the archive under its existing access and retention policy.

Next step

Open the editor and rebuild one real form first. If it works for your team, read Migrate from Tally for the full checklist.

Migrate from Tally: Plan the rebuild, archive, cutover, and rollback.
Embed a Fillo form: Choose a native React, DOM, or hosted form.
Author forms in code: Keep a typed Fillo schema in your repo.
Compare form tools: Find the right starting point for the form you need.
Headless form builder: See how a Fillo form works inside your app.
Fillo plans and limits: Check response, branding, and upload limits.
