It allows 15 projects per year, up to 100 responses per project, 200 responses per year, and 200 email invitations per year. Pro costs $99 a month and includes 1,250 responses per month, 15,000 responses per year, and 2,000 email invitations per month. Pro Max costs $199 a month, with 3,000 responses per month, 40,000 per year, and 4,000 email invitations per month. Surveys can contain up to 40 questions, and a 15-day trial is listed. Sogolytics, founded in 2013 and headquartered in Herndon, Virginia, lists API as its platform.

SurveyJS is a set of JavaScript components for building surveys, quizzes, polls, and web forms, then storing responses and displaying results. Its free, open-source Form Library renders JSON-based forms in React, Angular, Vue, and plain JavaScript applications. It supports more than 20 question types, conditional logic, validation, multilingual forms, and right-to-left languages. Survey Creator provides a drag-and-drop designer that generates JSON schemas. Dashboard displays results through interactive charts, tables, word clouds, and aggregated statistics; PDF Generator creates editable PDF forms and exports submissions. The libraries run in a customer’s application and can connect to any backend or database. SurveyJS says it does not access, process, or store survey data; customers choose and manage their own data storage and protections. React, Angular, and Vue have native support, while jQuery uses a wrapper over the Vanilla JavaScript version. The Form Library is free, but Survey Creator, Dashboard, and PDF Generator require commercial licenses for production use. Commercial developer licenses are required for each developer working with those product APIs or implementing integrations.
