Uptime Monitoring for Solo Founders in 2026: Real Prices
Every founder learns the same lesson once. Your site was down at 9pm, a customer emailed you about it at 10pm, and you found out at 11 the next morning. The fix is cheap, boring, and takes twenty minutes to set up. The confusion is in picking a vendor, because uptime monitoring prices look simple and then are not: free plans differ by a factor of fifty in what they watch, the check interval you actually need is often stuck behind the first paid tier, and the status page that impressed you in the demo turns out to be an add-on.

I priced the realistic options for a one-person company in November 2026, from each vendor’s own pricing pages, and worked out what the setup most founders actually want costs: a handful of monitors, checks every minute, alerts somewhere you will see them, and ideally a status page you can link to when a customer asks.
The short answer
- UptimeRobot has the biggest free plan in the business: 50 monitors checked every 5 minutes, commercial use allowed. Paid starts at 9 euros a month for 60-second checks.
- HetrixTools is the interval play. Its free plan checks 15 uptime monitors plus 15 server monitors every 60 seconds, which is the frequency most free plans make you pay for.
- Better Stack is the on-call play. Monitoring is near-free, and you are really buying incident response: schedules, phone calls, and polished status pages.
- Uptime Kuma is free forever if you have a machine that is never turned off, and it is the only option on this list whose vendor cannot go bankrupt without warning.
What you are actually choosing between
Uptime monitoring sounds like one product, but vendors split it into four things you get billed for separately: how many things you watch, how fast they check, where the alert lands, and whether you get a status page. The free plans compete loudly on the first one and quietly undercut you on the rest.
The frequency question matters more than people expect. A check every 5 minutes means an average outage is spotted up to two and a half minutes late, which is fine for a blog and embarrassing for a checkout flow. Every vendor will sell you the faster interval. The question is which one charges least for it.
UptimeRobot: the free plan is the product
UptimeRobot’s free tier is not a trial dressed up as generosity. Fifty monitors, checked every 5 minutes, and the company states the plan is fine for commercial projects. For a solo founder with a main site, an app, an API, a docs page and six client projects, the 50-monitor pool covers a lot of ground. This is why it is the default recommendation in every founder Slack, and that default is usually correct.
The paid tiers start where the free plan’s gaps are. Solo, at 9 euros a month billed annually (10 euros monthly), buys checks every 60 seconds, ten times the check history, and three status pages that can sit on your own domain. Team, at 35 euros a month annually, adds 30-second checks, more seats, and the webhook and PagerDuty integrations that only appear from this tier. Scale moves checks to every 15 seconds.
The honest read: if you are happy checking things every 5 minutes, the free plan may be the last uptime decision you make. The moment you need per-minute checks, you are on a 9-euro plan, which is still cheap, but no longer free. And if your alerts need to go somewhere custom, note that free accounts get a short list of integrations. Paid email and Slack alerts are the practical ceiling.
HetrixTools: per-minute checks without paying for them
HetrixTools inverts UptimeRobot’s tradeoff. Its free plan carries only 15 uptime monitors, but every one of them is checked every 60 seconds, on every plan including free. It also throws in 15 server monitors, so you can watch disk and memory on the VPS that runs everything, which most uptime tools treat as an upsell or ignore entirely. The paid tier, Professional at $9.95 a month (or $99.95 a year), expands the monitor counts rather than unlocking features, and the API comes with every plan.
Where this matters: fifteen monitors at per-minute frequency is a bigger upgrade over the free UptimeRobot experience than it sounds, because the thing you lose on free UptimeRobot is not monitor count, it is speed. If your product is a checkout page or an API that people wait on, 15 fast monitors beat 50 slow ones. If you are watching a portfolio of content sites where a 5-minute delay changes nothing, UptimeRobot’s 50 monitors win.
One caveat from the pricing comparison sites: HetrixTools’ dashboard looks dated next to Better Stack, and its status pages are functional rather than something you put in a customer-facing trust page. That matches the price.
Better Stack: you are buying the on-call, not the ping
Better Stack’s free plan is modest: 10 monitors plus heartbeat checks for cron jobs, and one status page, stated for personal use. Paid pricing does not work in tiers the way the others do. You buy a Responder license, $29 per month billed annually ($34 monthly), which is really a seat on an incident-response system: on-call schedules, unlimited SMS and phone-call alerts, incident timelines, and postmortem templates. Uptime checks on paid add-ons run as often as every 30 seconds, and extra status pages with custom domains cost about $12 a month annually.
For a solo founder, that is mostly inventory you do not need. On-call scheduling is for teams with rotations. The parts worth stealing from Better Stack’s free plan: heartbeats (dead-man switches that alert you when a scheduled job silently stops running) and the status page, which you can link from your app’s footer.
The honest read is that Better Stack earns its price for a two-to-five person team with an on-call rotation, and it is the wrong shape for one person with credit-card alerts in Slack. But of everything on this list, its status pages and mobile apps are the most polished, and if you grow, growing into it is painless.
Uptime Kuma: free, forever, with a catch
Uptime Kuma is open-source software under the MIT license that you run on your own server. It costs nothing, checks as often as every 20 seconds, supports multiple status pages, and has no plan, no upgrade, and no vendor. A sizable community of developers runs it on a $5 VPS and never thinks about it again.
The catch is structural, and the comparison sites say it plainly: your monitoring now runs on the same internet as your product, from wherever that server sits. If your host has a regional problem, both your site and your monitor die together, and nothing alerts you that the alerting itself is gone. Serious setups solve this by putting the monitor somewhere else, which starts to feel circular.
My take: Uptime Kuma is the right answer for a tinkerer who already has an always-on box and enjoys it, and a wrong answer for someone who wants monitoring to be a solved problem they never touch. There is no shame in paying $9 for someone else to worry about this.
The pricing table
| Tool | Free plan | Paid starts | Fastest checks | Status page |
|---|---|---|---|---|
| UptimeRobot | 50 monitors, every 5 min, commercial OK | Solo 9 EUR/mo annually (10 EUR monthly) | Every 15 sec (Scale) | 1 free; 3 with custom domain on Solo |
| HetrixTools | 15 uptime + 15 server monitors, every 60 sec | $9.95/mo or $99.95/yr | Every 60 sec on all plans | On every plan |
| Better Stack | 10 monitors + heartbeats, 1 status page | $29/mo annually per Responder license | Every 30 sec | 1 free, more about $12/mo |
| Uptime Kuma | Free, self-hosted, MIT | None | Every 20 sec | Multiple, included |
| Pingdom | Trial only | $16.50/mo annually for 10 checks | Not published | Separate product |
Two honest footnotes on that table. StatusCake, which older roundups list with a 10-monitor free plan, now shows a smaller free tier (3 monitors, every 15 minutes, personal use) on its own site, with its paid Superior plan around $20 a month billed yearly. Roundup articles disagree with each other on it, which is itself the lesson. And Oh Dear is worth a look if you run agency sites: 15 euros a month for 2 sites, no feature gating, but the free plan is a 10-day trial only.
What the founder setup actually costs
The realistic wishlist for a one-person SaaS: your site, your app, your API, maybe a landing page or two, checked every minute, with alerts to Slack and email plus a status page you can link customers to. Priced in November 2026:
- UptimeRobot Solo: 9 euros a month annually, checks every 60 seconds, three custom-domain status pages. Roughly $10 or so a month at late-2026 exchange rates, and it is the complete answer.
- HetrixTools free: $0, watches your four real monitors every minute and eight of your cron-driven servers besides. You give up the polish and the status page branding.
- Better Stack: $29 a month annually once you buy the Responder, plus $12 for extra status pages if you want a branded one. Call it $41 monthly for a setup heavier than you need alone.
- Uptime Kuma: $0 in software plus whatever your existing always-on server costs, which for most founders is already sunk. The real price is being your own operations team for it.
Notice that the spread between the best free answer and the best paid answer is about ten dollars a month. This is not a purchase that deserves an afternoon of deliberation. Pick one, spend the twenty minutes, and go back to whatever actually moves your business. The expensive failure mode here is not picking the wrong vendor; it is running your main product with no monitoring at all and hearing about the downtime from customers, again.
Things I would check before committing
- Confirm the current pricing page yourself. Two of the vendors on this list changed plan shapes within the last year, and third-party roundups still show old tables. Every number here was checked 2-4 November 2026 against vendor pages, but this market reprices often.
- Test the alert path on day one. Set up a monitor pointed at a URL that 404s, wait for the alert, and confirm it actually arrived where you live. An alerting system you have not seen fire is untested infrastructure.
- Heartbeats over cron monitoring, where possible. A dead-man switch attached to your nightly job catches silent failure in a way that an uptime check on the cron endpoint cannot.
- Decide on the status page question separately. If customers will ever look at it, vendor polish matters and Better Stack or UptimeRobot’s custom-domain pages win. If it is mostly an internal artifact, anything works.
Key takeaways
- UptimeRobot free (50 monitors, 5-minute checks) is nearly always the right first move. Its paid Solo tier, 9 euros monthly annually-billed, buys 60-second checks and branded status pages.
- HetrixTools free is the quiet better deal when speed matters: 15 monitors checked every 60 seconds, plus server monitoring, at no cost.
- Better Stack is priced for teams with on-call rotations; solo founders can take its free heartbeats and status page and stop there.
- The self-hosted route with Uptime Kuma is free, but it moves the operational burden onto you, which defeats the point for most founders.
- The whole decision is worth about $10 a month. Do not spend more than an afternoon on it, and do not skip it.
Try them in this order
Set up the UptimeRobot free plan first, because 50 free monitors cost you nothing and will cover everything you run today. Add HetrixTools if you decide 5-minute checks are too slow for anything customer-facing, since its free tier runs per-minute. Move to Better Stack only when you have teammates who need paging and schedules, and consider Uptime Kuma if you already keep a server running and enjoy tinkering. Whichever you pick, point one test monitor at a broken URL and watch the alert arrive before you trust any of it.
