Server, uptime and cron monitoring for solo builders. €9/month, open-source agent, no sales calls.
Five servers or fifty. A homelab, a side SaaS, a personal blog, a Telegram bot. One tool that costs less than the cheapest VPS you are monitoring.
Used by indie hackers, homelab users and weekend builders

Same intent, fewer dashboards.
Today · 4 tools, 0 integration
- UptimeRobot - free, but only uptime checks
- healthchecks.io - good cron checks, separate dashboard
- Grafana + Prometheus on a VPS - powerful, but another stack to maintain
- Manual SSH checks - when you remember

Built for indie operators who...
This is for people monitoring their own things, without a procurement process or a sales funnel.
-
Run a homelab on Proxmox, Unraid or bare metal
Track CPU, memory, disk and network across your nodes. The agent runs on standard Linux distros, including the one you installed last weekend.
-
Have a side SaaS and do not want enterprise pricing
Monitor production, your blog and your status page from the Starter plan. Move to Pro only when the project grows past 15 monitors.
-
Run cron jobs that cannot silently fail
Send heartbeats from scripts and get alerts when a job fails, runs late or stops pinging.
-
Want alerts where you already hang out
Telegram, Discord, Slack, email and webhooks. Pick a channel, paste a webhook and move on.
-
Need a public status page without another subscription
Publish a status page on your domain for a side project, blog, bot or small SaaS.
-
Care about open source and avoiding lock-in
The Linux agent is on GitHub. Audit it, fork it, contribute, and export your data through the REST API.
Everything for your homelab, VPS and side projects
Linux metrics, uptime checks, cron heartbeats, status pages, alerts and API access without stitching three tools together.
Server metrics, homelab-friendly
CPU, memory, disk, network, processes, Docker containers, Postgres, NGINX and Caddy. Works on VMs, LXC containers, bare metal and cheap VPS boxes.
