Frequently asked questions
Common questions about switching from Fillout to LeadToSheet.
- Will I still get reliable Sheets sync without Fillout's integration runtime?
- Yes - LeadToSheet writes to Sheets directly, not through an integration layer that can stall. There's no third-party runtime to monitor or re-authorize.
- How does the embed weight compare to Fillout's?
- LeadToSheet's runtime is a ~25 KB Preact embed that inherits your page styles. Fillout's bundle is significantly larger and prioritizes their builder UI being editable in place.
- Will I lose Fillout's HubSpot, Notion, and Airtable destinations?
- You can still pipe submissions to those destinations via webhook (HubSpot has a direct integration, Notion and Airtable via Zapier/Make webhooks). The default Sheets sync just removes the integration layer for the most common case.
- What does schema versioning give me that Fillout doesn't?
- Every submission is stored against the form schema that produced it, so when you rename or remove a field, historic submissions still resolve their original field labels. Fillout (and most builders) overwrite the schema, which makes old responses harder to interpret after the form changes.
