Describe the survey you need in one sentence, and TDuck drafts the questions for you. This open-source form platform replaces hosted tools like Typeform with a version you run on your own server, so responses never leave your hands. The visual designer offers over 27 field types, from text, dates, and ratings to file uploads, signatures, cascading selects, sub-forms, and matrix scales. Logic rules show or hide questions based on earlier answers, and imported question lists save time on long forms. Appearance settings cover header images, backgrounds, colors, and button text. Each form can be limited by device, account, IP, or WeChat identity, with an answer window you set. Finished forms publish as links or QR codes, and a recycle bin recovers deleted ones. Statistics show views, completion rate, weekly trends, submission maps, and per-question pie or bar charts that export as images. Responses can be edited, exported, printed, or zipped with attachments. Webhooks fire on new, changed, or deleted entries, a sync API exposes all data, and email, SMS, and WeChat notices keep owners informed. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.
