What Glassmkr is
Glassmkr monitors Linux servers and hardware, identifies issues that need attention, and suggests a command to run next. Its 72 alert rules cover storage, memory, CPU, power, cooling, networking, operating system state and GPU hosts. Each alert presents evidence, a check to run and remediation guidance, but the agent does not execute fixes. Notifications can go to email, Telegram, Slack, Discord, PagerDuty or webhooks, with priority filtering by channel. An API supports server onboarding and account automation with tools such as Ansible, Terraform, scripts and MCP clients. Installers support Debian, Ubuntu, RHEL, Rocky, Alma, Fedora and CentOS families; a single-file binary is available for other distributions. The agent runs as an unprivileged glassmkr user, connects over HTTPS, and sends metrics, alert state and bounded diagnostic excerpts rather than bulk logs or arbitrary file contents. Hosted data is stored in Amsterdam, while self-hosted telemetry stays on the operator’s network. Both options are free: hosted accounts allow up to 10 nodes with 90-day retention, and self-hosted use has no node limit. It does not replace application tracing, external uptime checks or Kubernetes monitoring.
Who it suits
Glassmkr is aimed at people responsible for Linux servers without a dedicated infrastructure team, including application, game, storage, small-business and homelab operators.
What it does well
- 72 rules cover server and hardware alert areas.
- Alerts include evidence, checks and remediation guidance.
- Six listed notification channels support priority filtering.

- Does not provide Kubernetes monitoring.
- The agent does not execute fixes.
- No formal SLA or dedicated on-call team.
Plans
| Plan | Billed and limits | Price |
|---|---|---|
| Self-hosted Glassmkr | Free to run on your own hardware · No node limit · You operate databases, upgrades, backups, and TLS | Free |

As glassmkr.com lists them, read 11 Oct 2026. The maker's own page has the final word.
Verdict
Glassmkr offers server and hardware monitoring with useful alert context and several notification options. Its scope is deliberately limited, and self-hosted users operate the databases, upgrades, backups and TLS themselves.
