Glances vs Maintenant

Glances is a free, open-source, cross-platform tool for monitoring real-time system statistics and running processes. Its listed coverage includes CPU, memory, load, processes, network, disk I/O, sensors, filesystems, containers, alerts, and uptime. Client/server mode enables remote monitoring through a terminal, web interface, or API, while its built-in web UI lets users view a system from a browser-equipped device. Statistics can be exported to CSV or JSON files, databases such as InfluxDB and Prometheus, brokers such as RabbitMQ and Kafka, or a REST endpoint. The project documents Docker and Podman support and describes Docker and LXC container monitoring in its README. Installation options include pip, pipx, Homebrew, Linux and FreeBSD packages, and Docker images. Glances 4 requires Python 3.10 or higher. Its default installation does not include web interface dependencies; separate extras cover features such as web, GPU, containers, exports, and MCP. Version 4.5.1 and higher can provide an MCP server for AI assistants. The project uses the LGPL version 3 license.

Maintenant is a self-hosted, single-container dashboard for monitoring Docker and Kubernetes infrastructure. It tracks containers, HTTP and TCP endpoints, cron heartbeats, TLS certificates, and CPU, memory, network, and disk metrics. It can discover containers automatically, monitor health and restart loops, and stream logs. Update Intelligence checks OCI registries for image digest changes, while security insights identify exposed ports and risky configurations. The software uses SQLite by default, can be configured to use PostgreSQL, and does not require a separate datastore service. A REST API, real-time SSE streams, and an MCP server connect it to other systems and AI assistants. Community includes webhook and Discord alerts; paid editions add email and Telegram, and Pro adds Slack, Teams, and escalation policies. Community is free forever. Personal costs €149, paid once, including one year of updates; further updates cost 59 € incl. VAT per year. Pro costs €29 a month excluding VAT, or 290 € excluding VAT per year. There is no built-in authentication, so the dashboard and admin API need protection through a reverse proxy and authentication middleware.
