## What it is
TEAMMATES is a free, cloud-based online tool for managing peer evaluations and other feedback paths for students, used by hundreds of universities worldwide. It is a full-stack web application built with Java and Angular/TypeScript, provided as a hosted service for educators and students.

## Use cases
- manage peer evaluations for university students
- collect structured feedback from students about teammates
- run anonymous feedback sessions between students and instructors
- coordinate team-based assessment in courses
- gather instructor-to-student and student-to-student feedback
- track and grade student contributions in group projects

## When to choose
- you are an educator or institution needing a hosted peer-evaluation system
- you want a mature, widely adopted feedback tool used by hundreds of universities
- you need structured feedback paths (student-to-student, student-to-instructor) rather than generic surveys
- you want a free, open-source alternative to commercial survey tools for education

## When to avoid
- you need a general-purpose survey or form builder rather than education-focused peer feedback
- you need a self-hosted on-premise deployment without cloud infrastructure
- you are not in an educational context and need corporate performance reviews or HR feedback
- you need a lightweight library to embed feedback features into your own app rather than a standalone service
