Overview

OpnForm is an open-source builder for forms, surveys and workflows. Fields are dragged into place, with conditional logic, calculations, computed fields, themes and either classic or conversational layouts, then shared by link, embed, Notion, custom domain or QR code. Responses route to Slack, Google Sheets, Zapier, Stripe and webhooks, and it runs on OpnForm's cloud, EU hosting or self-hosted.

Best for: Teams that need unlimited form responses and the option to self-host or keep data in the EU
Pricing: The Free plan is $0 with unlimited submissions and Pro, Business and Enterprise are paid cloud plans with 15% off yearly billing, but the captured pricing page shows $0 placeholders instead of their real rates; self-hosting is free for the Community Edition or $1,999/year per instance for the Enterprise licence.
Runs on: WebSelf-hosted
