Paid Web

What Weclare is

Weclare is a free, open-source web classroom response system made for university computer science education. Instructors send questions, and students answer interactively in their browsers without downloading an app. Participating browsers connect directly, while the server mainly handles signalling. Questions can include Java code snippets that students compile and run in the browser. Java snippets support indentation and syntax highlighting. An executable Java example can appear only once in a question and remains separate from the question text. Free-text questions are not supported. The project describes classroom response systems as usable on computers, tablets, and smartphones. Weclare is available through the web, although its official site requires JavaScript. The repository identifies a GPL-3.0 license and gives a local setup using npm install, npm start, and localhost:3000. The project came from Moritz Stückler’s bachelor thesis at HAW Hamburg. Its focus is interactive questioning for university-level computer science classes rather than broad classroom surveying.

Who it suits

Weclare suits university computer science instructors who want browser-based interactive questions, especially questions containing executable Java examples. It also fits learners using computers, tablets, or smartphones without downloads.

What it does well

Free and open-source GPL-3.0 project
Runs in web browsers without downloads
Compiles and executes Java snippets
Supports indentation and syntax highlighting
Works across computers, tablets, and smartphones

What to know first

Prototype focused on university computer science
Free-text questions are unsupported
Only one executable Java example per question
Official site requires JavaScript

Verdict

Weclare offers a focused browser classroom tool for interactive university computer science questions. Its executable Java support is useful for code-based teaching, while the prototype scope and unsupported free-text format limit broader uses.
