Tally
Beautifully simple form builder with a Notion-like interface — free for most users
Best for: Teams that want beautiful forms for free and don't need self-hosting
Overview
Tally is a form builder with a Notion-like block editor that makes creating forms feel like writing a document. While not open source, it’s worth including here because its generous free tier (unlimited forms, unlimited responses) often makes it the pragmatic choice over self-hosted alternatives.
Tally’s free plan covers what Typeform charges $25-83/month for: conditional logic, calculations, hidden fields, and custom branding. The paid plan ($29/month) adds integrations, file uploads, and team features.
