# What is Dozzle?

Dozzle is an open-source project sponsored by Docker OSS. It is a lightweight, web-based log viewer designed to simplify monitoring and debugging containerized applications across Docker, Docker Swarm, and Kubernetes environments.

## Key Features

###  Real-time Monitoring

Stream logs from running containers with instant updates. Live CPU, memory, and network metrics with historical visualizations.

###  Flexible Deployment

Run as a [standalone server](/guide/getting-started), a [Swarm](/guide/swarm-mode) deployment, a [Kubernetes](/guide/k8s) install, or with [remote agents](/guide/agent) across multiple hosts.

###  Advanced Log Handling

Automatic JSON detection and color coding, multi-line stack-trace grouping, [filters](/guide/filters), and an embedded [SQL engine](/guide/sql-engine) for ad-hoc queries.

###  Multi-Host Support

Monitor containers across multiple Docker hosts from one UI. See [agents](/guide/agent).

###  Interactive Terminal

Attach or exec into running containers from the browser. See [Shell Access](/guide/shell).

###  Container Actions

Start, stop, restart, and update containers directly from the UI. See [Actions](/guide/actions).

###  Alerts & Webhooks

Match log patterns, CPU and memory thresholds, or container events, and send them to Slack, Discord, ntfy, or any webhook. See [Alerts and Webhooks](/guide/alerts-and-webhooks).

###  Authentication

Run open, or add [authentication](/guide/authentication): a `users.yml` file, sign-in with GitHub or any OpenID Connect provider, or a forward proxy such as Authelia, all with role-based access control.

###  Lightweight & Fast

Go backend, Vue 3 frontend, streaming over SSE and WebSocket — minimal resource footprint.
