# Website uptime monitoring with down alerts

> Lampwick requests your URL every 30 seconds to 1 hour and sends a down alert after 2 failed checks in a row. Free plan: 3 monitors every 5 minutes.

An uptime monitor requests one public URL on a fixed interval, from Lampwick's servers, and tells your team when it stops answering. After 2 failed checks in a row the monitor is **Down** and everyone on the team gets **Down: MONITOR** by push and e-mail, with the reason first. You add it by pasting a URL; your app needs no code.

## What you get

- **Checks every 30 seconds to 1 hour.** The shortest interval depends on the plan: as often as every 5 minutes on Free, every minute on Pro, every 30 seconds on Team and Business.
- **A quick second look.** After a first failure, Lampwick checks again within 15 seconds. One dropped request alerts no one; a real outage is noticed within one interval plus about 15 seconds.
- **The reason in the alert.** `HTTP 503`, `timed out after 10 s`, a DNS or TLS error: the alert says which, and shows the host and path of the URL, never the query string.
- **Up again.** **Up again: MONITOR** after the first successful check, only after a down alert.
- **Response times.** The monitor's page shows uptime for the selected range, average and p95 response time, and the latest checks with status, duration and error.
- **SSL, domain and DNS on the same monitor.** Every monitor also checks its [certificate](/features/ssl-monitoring/) and [domain](/features/domain-monitoring/), with no extra setup.
- **Alerts where your team works.** Push in the Lampwick iOS app, e-mail, and [alert channels](/docs/alerts/#alert-channels) for Slack, Discord, Microsoft Teams or a signed webhook.
- **Fewer alerts on purpose.** At most one down alert per monitor per 30 minutes when a site flaps, and a mute switch per monitor.

## How a check decides up or down

| Rule | Value |
|---|---|
| Up | The final response, after redirects, has status 2xx or 3xx. |
| Failed check | Any other status, no response headers within 10 seconds, a DNS, connection or TLS error, or more than 5 redirects. |
| Down | 2 failed checks in a row. |
| Back up | 1 successful check. |
| Request | `GET`, User-Agent `lampwick-uptime/<version>` |

## Check if your website is down, then stop checking by hand

To check by hand, open the site in a private window or run `curl -I https://example.com`; [how to know when your app is down](/guides/know-when-your-app-is-down/) goes through the usual causes. An uptime monitor does that check for you, all day, and alerts when it fails twice in a row.

## Set it up in a minute

1. [Create an account](https://app.lampwick.dev/signup) and a project.
2. Go to **Uptime** in the sidebar and paste the URL under **Add monitor**, such as `https://example.com/up`.
3. Pick **Check every** and click **Add monitor**. The first check runs within seconds.

Monitor a light health endpoint (Laravel's `/up` route, for example) rather than a heavy page. Behind Cloudflare or another WAF, allow the User-Agent `lampwick-uptime`. Details: the [uptime docs](/docs/uptime/). An AI agent can add monitors too, over the [MCP server](/docs/mcp/).

## What it doesn't do

- Checks come from one place, Lampwick's own servers. There is no confirmation from a second location.
- It checks the status code, not the page's content: no keyword checks, no `POST`, no custom headers.
- No ping, TCP port or Lighthouse checks.
- Alerts go by push, e-mail, Slack, Discord, Microsoft Teams or webhook. No SMS, phone calls or PagerDuty.
- Only public `http://` and `https://` URLs. Private and loopback addresses are refused.

## What it costs

| Plan | Price per team | Uptime monitors |
|---|---|---|
| Free | €0 | 3, every 5 min |
| Pro | €29 / month | 20, every minute |
| Team | €79 / month | 100, every 30 s |
| Business | €199 / month | 300, every 30 s |

SSL, domain and DNS checks come with every monitor on every plan. The plans also include error and request monitoring: see [pricing](/#pricing).
