The composable content platform for structured, multi-channel, AI-assisted publishing
Define reusable content types and fields rather than pages, so the same entry can be recomposed into different layouts across channels without duplication.
Content is served through REST and GraphQL APIs plus SDKs, letting any front end or service consume it without depending on a fixed presentation layer.
Locale-aware entries, roles, editorial workflows and environments support multi-market publishing with review and release control.
AI assistance sits inside the editorial workflow for drafting, editing, translation and enrichment, helping teams produce and adapt content at volume.
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.
