Open-source form builder with AI assistance and unlimited responses
The full codebase is public and auditable, and you can run OpnForm on the vendor cloud, an EU-hosted instance, or your own infrastructure for complete data ownership.
Optional AI help for building forms and fields, designed to stay out of the way when you would rather write everything yourself.
Conditional logic, computed fields, answer piping, hidden fields and redirect-on-submit rules let one form adapt to many different respondents.
Collect as many responses as you need even on the free plan, with no hidden quotas or surprise overage charges.

The AI workspace where teams and agents get work done together
Combine docs, wikis, projects, and databases into one structured system of record that stays linked as your content grows.
Draft, summarize, translate, and answer questions inline, or build custom agents that automate recurring workflows around the clock.
Find answers instantly across Notion and connected apps, with citations so you can verify where each answer came from.
Use relations, rollups, views, and a large template gallery to model anything from a CRM to a content calendar.
