Blik is an open source, self-hosted platform for anonymous 360-degree feedback and performance review cycles, built with a strong focus on privacy, transparency, and developer-friendly deployment.
It allows organizations to run review cycles where employees get anonymous feedback from peers, managers, and direct reports, without vendor lock-in or per-user licensing costs.
The system is built using the Django framework, with a PostgreSQL backend, and is packaged for easy deployment via Docker Compose, making it accessible for small teams or startups to spin up on their own infrastructure.
One of the core design choices is true anonymity: reviewers use token-based links rather than user accounts, and the architecture is designed so that even administrators cannot trace responses back to individuals under normal operation.
Features
- Anonymous feedback collection via tokenized reviewer links with no reviewer authentication required
- Pre-built, customizable review questionnaires using frameworks like the Dreyfus skill-model
- Admin dashboard for managing review cycles, tracking invite status, and monitoring participation
- Analytical reports and radar-chart visualizations of aggregated feedback while enforcing anonymity thresholds
- Easy self-hosted deployment via Docker Compose (or full production stack with Nginx, Gunicorn, PostgreSQL)
- Open-source under AGPL-3.0 with full data export and self-hosted control for privacy and compliance
