What Sonadier is

Sonadier is an online database application platform for building custom business applications with forms that represent database tables. The maker says forms and fields have no quantity restrictions, and hosted data can be reached from any device. Organizations can share permissions with partner organizations and revoke access when needed. Group-based permissions control access to selected forms and reports. Team users can create trigger-action workflows for notifications, integrations, and record assignment. Zapier connections provide integrations with hundreds of applications. Developers can use JavaScript in the browser or on the server and connect external applications through a REST API that documentation describes as beta-stage. Sonadier supports spreadsheet imports and exports form data as XML, JSON, or CSV. Its OAuth service currently supports Salesforce and Force.com. The Free Plan costs nothing for five users or fewer, with unlimited forms and fields and two default groups. A 14-day trial is listed.
