Formscaler Core · Apache-2.0
The core is everything one team needs to model data, govern it, publish it and connect agents. Team and Enterprise add workflow and control, never the basics.
Features that make one team productive and safe are open. Features that coordinate many teams or satisfy procurement are commercial.
Collections, 12 field types and relations · drafts, publishing and locking · dynamic roles with collection, record and field permissions · generated admin · REST API with OpenAPI · MCP server for agents · pages with live preview · import, export and audit log · plugins and adapters · SQLite or PostgreSQL · Docker image.
Approvals · scheduled publishing · version history and rollback · comments · shared views · webhooks packs (Team). SSO and SCIM · audit export and SIEM · enforced 2FA · IP allowlists · BYOK · external-database adapters · per-agent MCP governance · SLA (Enterprise).
Apache-2.0. Use it, modify it and ship it commercially.
The core never phones home.
Schemas and records export as JSON. You can always leave.
Paid features register through an extension seam, so the open code stays free of plan logic.
17 architecture decision records explain every extension point and trade-off.
Rails 8.1, SQLite or PostgreSQL, Hotwire and Solid Queue.
Add Team for editorial workflow, or Enterprise for identity and governance.
