TDuck

TDuck is an open-source questionnaire and form platform for enterprises that need to collect and manage business data. It supports private deployment and replaces manual collection workflows with a configurable data entry and publishing system.

Forms are built by drag and drop using 27+ custom components, including text, date, file upload, ordering, cascades, and subforms. It supports batch component import, conditional display logic, data export and print preview, attachment downloads, real-time chart analysis, post-submit redirects, submission limits by IP, device, and attempt count, email reminders, an API for data sync, and webhooks for add, change, and delete events.

TDuck ships in community, Pro, and TDuckX editions. It is built on Spring Boot and Vue, deploys with Docker, and offers file storage on Aliyun, Qiniu, UpYun, local disk, or generic S3. The license is MIT.
