Better Stack vs UptimeRobot for a Side Project: Free Tiers, Check Intervals and Status Pages

Your side project does not need an observability platform. It needs one thing: when the site goes down, you find out before a customer emails you. Everything else, such as dashboards, incident timelines and on-call rotations, is nice to have, and most of it is built for teams you do not have.

For that one job, two hosted services come up again and again: UptimeRobot, the long-time default with a generous free plan, and Better Stack, the newer, more polished option that bundles monitoring with incident management and status pages. I have run both on small paid products, where every missed outage is a refund request and every false alarm is a ruined evening. Here is how they compare when the whole engineering team is you.

If you want the simplest thing that works, and the most monitors for free, use UptimeRobot. It does basic uptime checks well, and it has done for years.

If you want alerts that wake you up reliably, fewer false alarms, and a status page that looks professional to paying customers, use Better Stack. Its free tier is smaller, but what it does include is better designed for the moment something actually breaks.

A note on free tiers

Both companies change their plans regularly. Monitor counts, check intervals, and what counts as commercial use have all shifted over the years. Treat any specific numbers you read here or anywhere else as a snapshot, and check the current pricing pages before you decide. The broad shape has stayed stable, though: UptimeRobot gives you more monitors with longer intervals; Better Stack gives you fewer monitors with more features around each one.

A focused monitor and a monitoring suite

UptimeRobot does one thing: it checks your URLs, ports and servers from the outside on a schedule, and alerts you when they stop responding. It supports HTTP checks, keyword checks (is this text still on the page?), ping, port checks, and heartbeat monitoring for jobs that check in. It has simple public status pages. It is fast to set up and stays out of your way.

Better Stack started as an uptime monitor and grew into a suite: uptime checks, incident management with acknowledgement and escalation, on-call scheduling, status pages, and log management. For a side project, the uptime and incident parts are what matter. It does the same kinds of checks as UptimeRobot, but wraps each failure in an incident you can acknowledge, comment on, and close, with a timeline of what happened.

Check intervals: how fast you find out

The interval between checks is the main thing a free plan rations. On a long interval, your site can be down for several minutes before the first failed check, and then the monitor needs to confirm the failure before it alerts. In practice, you hear about an outage several minutes after it starts.

For a hobby site, that delay does not matter. For a product with paying users, it matters more than people expect. A five-minute outage you never hear about is invisible. A five-minute outage your customer hears about before you do is a support ticket and a lost trial. If your project has revenue, a paid plan with one-minute checks on your most important endpoint is one of the cheapest forms of insurance you can buy.

A useful middle ground is to spend your free monitors carefully: one check on the homepage, one on the login or checkout page, and one on an API health endpoint that actually queries the database. A homepage served from a CDN can stay up while the app behind it is broken. Keyword checks help here: check that the page contains text that only renders when the app is working, not just that it returns a 200.

Alerts: the part that actually matters

An uptime monitor is only as good as its alert. If the alert lands in an email inbox you check twice a day, the monitor is a history log, not an alarm.

UptimeRobot sends alerts to email, its mobile app, and a range of integrations such as Slack, Telegram, Discord and webhooks. That is plenty for most side projects. Push notifications from the app are the practical choice for getting woken up. Phone calls and SMS are paid extras.

Better Stack treats alerting as the core product. An outage becomes an incident, and the incident keeps notifying you until someone acknowledges it, escalating from push to SMS to a phone call if you set it up that way. For a solo founder, that escalation is the killer feature. A push notification is easy to sleep through; a phone call that keeps coming back is not. Phone and SMS alerts are paid here too, but the escalation logic is built in.

False alarms are the other half of alerting. A monitor that pages you because one checking location had a network blip trains you to ignore it. Better Stack confirms failures from several locations before opening an incident, and it records screenshots and error details, which makes it easier to tell a real outage from noise. If you have ever been woken by a monitor that turned out to be wrong, this matters more than any feature on the pricing page.

Status pages for customers

Once a project has paying users, a public status page saves you from answering “is it down?” one email at a time.

UptimeRobot’s status pages are functional: a list of monitors with their uptime history. They do the job, and custom domains and branding are available on paid plans.

Better Stack’s status pages are noticeably nicer. They are customisable, support incident updates written for customers, and look like something a real company would publish. If your customers are businesses, that polish signals that someone is paying attention.

One caution with any public status page: be careful what you name your monitors. Internal hostnames, server names and endpoints that you would not otherwise publish end up visible to anyone, and status pages leaking hostnames is a common, avoidable mistake.

Heartbeats for background jobs

Uptime checks only see what is reachable from outside. Your nightly backup, the cron job that sends invoices, the queue worker that processes signups: none of these have a URL. When they stop, nothing on the outside changes.

Both services offer heartbeat monitoring: the job pings a unique URL every time it runs, and if the ping does not arrive on schedule, you get an alert. Availability depends on the plan, so check before you rely on it. For a side project with several scheduled jobs, heartbeats often catch more real problems than uptime checks, because jobs fail silently far more often than websites go down.

What it costs as you grow

UptimeRobot’s paid plans are inexpensive and priced mostly by the number of monitors and the check interval. For a solo developer, the upgrade is cheap and predictable.

Better Stack’s paid plans cost more, and the price grows with features and with the number of people on call. As a solo founder you are one responder, which keeps it reasonable, but it is the more expensive choice, and you are paying for incident management you may not fully use yet.

There is also a third option: self-host. Uptime Kuma gives you most of what UptimeRobot does, for the cost of a small server. The catch is that a monitor running on your own infrastructure can go down with it, which is the trade-off explored in Uptime Kuma vs Better Stack. For a product people pay for, at least one check should run somewhere you do not control.

Free and simple, or paid and loud

UptimeRobot covers you when:

• You have several small sites or projects and want to watch them all for free.
• You want simple up/down monitoring with minimal setup.
• Your project is a hobby or early-stage, and a few minutes of delay before an alert is acceptable.
• Cost matters more than polish.

Better Stack earns its price when:

• Your project has paying users, and missing an outage costs money.
• You want alerts that escalate until you respond, including phone calls.
• False alarms have burned you before.
• You want a professional status page for customers.

Whichever you choose, the setup matters more than the brand. Check the endpoint that proves the app works, not just the homepage. Send alerts somewhere that actually wakes you. Add heartbeats for the jobs that run while you sleep. A free UptimeRobot account set up carefully beats a Better Stack subscription pointed at the wrong URL.
