These are the limits Fillo enforces or publishes as of August 27, 2026. Product and provider safety limits can change, so check that date before building a hard dependency on a number.
Plans
| Allowance | Free | Everything |
|---|---|---|
| Price | €0 or $0 per month | €35 or $39 per month |
| Builder forms | Unlimited | Unlimited |
| Code-defined forms | Up to 200 per workspace | Up to 200 per workspace |
| Completed responses | 200 per month | 5,000 per month, then €0.007 ($0.008) each |
| Default-renderer branding | Powered by Fillo visible | Optional |
| Support | Community | Priority email |
Free has no time limit and needs no card. Everything is free for the first 30 days, then €35 or $39 per month. Above 5,000 completed responses, each additional response costs €0.007 in EUR or $0.008 in USD (€7 or $8 per 1,000). Fillo calculates the overage from exact usage, rounds the monthly total to the nearest cent, and keeps the form collecting.
Every embed method, field type, save and resume, response limits, connected storage, CSV export, signed webhooks, and the supported integrations are available on every plan. The Everything plan changes response scale and support, not renderer access.
Schema limits
| Item | Limit |
|---|---|
| Serialized schema accepted by sync and save | 200,000 bytes |
| Pages per schema | 50 |
| Blocks per page | 500 |
| Options, matrix rows, or matrix columns per field | 200 |
| Conditions in one normalized condition list | 20 |
| Jump rules on one page | 50 |
| Field or page ID length | 128 characters |
Normalization also caps labels, descriptions, option labels, and content text. A schema isn't document storage — keep forms focused.
File field limits
| Item | Limit |
|---|---|
| Files in one field answer | 1 by default, configurable up to 20 |
| Size of one file | 500 MB by default, configurable from 1 MB to 5,000 MB |
| Accepted type rules | Up to 50 extensions or MIME patterns |
The field limit isn't a promise that every connected provider, browser, network, proxy, or account quota will accept a 5 GB file. Google Drive, Box, S3/R2, and the host environment keep their own quotas and multipart constraints.
An eligible newly provisioned workspace can use Fillo's temporary transit storage before customer-owned storage is connected. That lane is limited to 10 MB per file and 100 MB of active files or reservations per workspace. An incomplete upload holds capacity for one fixed hour from initialization, and completed files expire after seven days.
Public write rates
The response endpoint allows up to 30 submissions per form and client IP per minute, with aggregate ceilings of 600 per form and 1,200 per workspace per minute. Uploads and draft/session writes have separate endpoint, form, workspace, and byte-volume controls. A limit response returns HTTP 429.
These are abuse ceilings, not throughput you've purchased. Spread legitimate batch work over time and retry only after Retry-After where it's present.
Management API rates
Project API keys allow 120 requests per minute per key, with an aggregate ceiling of 240 per minute across the workspace. List endpoints accept limit from 1 through 100 and use keyset cursors.
Unclaimed preview workspace
An agent-provisioned workspace stays capped until its owner claims it from the email. The current preview cap is 10 responses across the workspace, and the claim has a time window too. Claim it before putting real traffic on the form.
