More than ping checks. Less than an observability suite.
A simpler UptimeRobot alternative for small teams: uptime checks, heartbeats, alert routing, status pages, and agent-assisted setup in one lightweight product.
No credit card · free plan · up and watching in minutes.
The problem
As your app grows, a single outside ping isn't enough — you also want heartbeats for cron jobs, a status page your users can check, and alerts routed to the channel your team actually watches. A full observability suite does all that and far more, at a price and a rollout most small teams don't need yet.
Set up in three steps
Add your first monitor
An outside check for a site or API, or a heartbeat URL for a cron, queue, or backup.
Route your alerts
Send alerts to email, Slack, Discord, or a webhook — no per-seat notification fees.
Publish a status page
Turn on a status page connected to the same monitors, updated automatically.
What Holter does
Holter sits in between: outside checks and inbound heartbeats, alerts routed to the channel your team actually watches, a status page that updates itself, and an MCP server so your coding agent can help set it all up — without the enterprise price tag.
