About Sentry
Sentry is an open source debugging platform for detecting, tracing, and fixing software issues in real time. It lives in the developer infrastructure ecosystem and provides error tracking and performance monitoring across languages, frameworks, and runtime environments.

About dozzle
Dozzle is a lightweight, web based application for monitoring Docker logs in real time. It is written in Go and distributed under the MIT license, and it lives in the container and orchestration ecosystem alongside Docker, Docker Swarm and Kubernetes, which its topics and tagline both name. The project ships as a small container — roughly 7 MB compressed — and its user interface is built with Vue.js. It exposes a browser view over logs rather than writing them anywhere: the README states plainly that Dozzle stores no log files and exists purely for live log viewing.
