Best Uptime Monitoring Tools for Indie Hackers in 2026: UptimeRobot vs Better Stack vs Uptime Kuma vs Checkly

Originally published at devtoolpicks.com

You shipped your SaaS. It is running on Railway or Render or a Hetzner VPS. Users are signing up. And then at 3 AM, your database connection drops, your app returns 502s for two hours, and you wake up to angry support emails.

Uptime monitoring exists to catch that before your users do. It checks your URL every few minutes and pings you when something breaks. Simple concept, dozens of tools doing it.

Here are the four worth considering as an indie hacker, what they actually cost, and which one to pick.

Quick verdict

UptimeRobot

UptimeRobot has been around since 2010. Over 3.2 million users. It does one thing well: check if your site is up and tell you when it goes down. That simplicity is the entire value proposition.

Pricing:

• Free: 50 monitors, 5-minute check intervals, 1 basic status page, 3-month data retention
• Solo: $9/month annual ($10/month monthly), 50 monitors, 1-minute intervals
• Team: $38/month annual ($45/month monthly), 50 monitors, 1-minute intervals, 3 login seats
• Enterprise: $69/month annual ($82/month monthly), 200+ monitors, 30-second intervals

The free plan gives you 50 monitors with 5-minute checks. No other tool in this list comes close to that on a free tier. You can monitor your production app, your staging environment, your API endpoints, your status page, and your documentation site all at once without paying a cent.

The 5-minute interval means there is a window where your site could be down for up to 5 minutes before UptimeRobot notices. For most indie hacker projects, that is fine. If you need 1-minute checks, the Solo plan at $9/month gets you there.

UptimeRobot supports HTTP, keyword, ping, port, and heartbeat monitors. You can verify that a specific string appears on your page (not just that it returns 200). It integrates with Slack, Discord, Telegram, PagerDuty, and 15+ other services.

One important caveat: UptimeRobot's free plan is for personal, non-commercial use only according to their terms of service. If you are running a SaaS product commercially, you technically need a paid plan. Most solo developers start on free and upgrade when revenue comes in, but it is worth knowing.

SMS and voice call alerts are not included on any plan. You buy credits separately starting at $3 for 10 credits. If your monitors fire frequently, this adds up. Stick with Slack or email notifications unless you specifically need phone alerts.

Who should NOT use UptimeRobot: Teams that need incident management, on-call scheduling, or advanced observability in the same tool. UptimeRobot is a monitoring tool, not an incident response platform. If you need the full stack, look at Better Stack.

Better Stack

Better Stack (formerly Better Uptime) is the modern all-in-one alternative. It bundles uptime monitoring, incident management, on-call scheduling, status pages, and log management into a single platform. The trade-off is complexity and price.

Pricing:

• Free: 10 monitors, 3-minute checks, 1 status page, Slack and email alerts
• Responder: $29/month annual ($34/month monthly) per license, unlimited phone/SMS alerts, unlimited team members
• Additional 50 monitors: $21/month (annual) to $25/month
• Telemetry bundles (logs, metrics): $25 to $500+/month based on volume

The free plan gives you 10 monitors with 3-minute checks, plus a status page with a custom domain. For a single SaaS product with a handful of endpoints, that is enough to get started. The 3-minute default is faster than UptimeRobot's 5-minute free checks.

What sets Better Stack apart is everything beyond basic uptime. The Responder plan at $29/month includes on-call scheduling with escalation policies, incident timelines, and unlimited phone and SMS alerts. If you are a solo founder, you do not need on-call rotation. But the moment you bring on a co-founder or a part-time contractor, having structured incident management becomes valuable.

Better Stack also checks from at least four locations simultaneously and only creates an incident after three locations confirm the failure. This reduces false positives, which is one of the most annoying problems with basic monitoring tools.

The pricing can get complex. The base $29/month covers one responder license. Adding monitors, logs, and metrics comes as separate charges. For a solo indie hacker, this means Better Stack can quickly become $50 to $100/month if you use the full platform. Compare that to UptimeRobot at $9/month for the same number of monitors.

Who should NOT use Better Stack: Solo developers who just need "is my site up?" monitoring. The all-in-one platform is overkill if you do not use incident management or logging. You will pay more for features you ignore.

Uptime Kuma

Uptime Kuma is the self-hosted option. It is open source, free forever, and runs on any VPS or Docker host. If you already have a server, you can have uptime monitoring running in under 5 minutes with zero recurring cost.

Pricing:

• Free. Always. Unlimited monitors. Unlimited checks. No tiers, no limits, no catch.

Install it with Docker (docker run -d -p 3001:3001 louislam/uptime-kuma), open the dashboard in your browser, and start adding monitors. The interface is clean, responsive, and genuinely well-designed for an open source project.

Uptime Kuma supports HTTP, TCP, DNS, Docker container, and push monitors. It has built-in status pages with custom domains. It sends alerts through Slack, Discord, Telegram, email, webhooks, Gotify, Ntfy, and over 90 other notification services. The notification integration list is larger than most paid tools.

The check interval goes down to 20 seconds if you want it. No paid tier required. No credits to buy. Your server, your rules.

The obvious trade-off is that you are responsible for keeping Uptime Kuma itself running. If your VPS goes down and takes Uptime Kuma with it, you will not get an alert about anything. The standard solution is to run Uptime Kuma on a different server or provider than your production app. A $5/month DigitalOcean or Hetzner droplet dedicated to monitoring solves this. That $5/month still costs less than any paid monitoring service.

Uptime Kuma has 64,000+ stars on GitHub and a very active community. It is maintained by a single developer (Louis Lam) with regular releases. The project is mature and stable enough for production use.

Who should NOT use Uptime Kuma: Anyone who does not want to manage a server. If the idea of maintaining a Docker container sounds like work you do not want to do, use UptimeRobot. Also not ideal if you need multi-location checking out of the box. Uptime Kuma checks from wherever you host it, which means single-location by default unless you set up multiple instances.

Checkly

Checkly is the developer-first option. It is built around a concept called "monitoring as code." You write your checks in JavaScript or TypeScript, store them in version control alongside your application code, and run them from your CI/CD pipeline. Checkly also does standard uptime monitoring, but that is not its main selling point.

Pricing:

• Hobby (Free): 10 uptime monitors, 10,000 API check runs/month, 1,500 browser check runs/month
• Team: $64/month, more monitors, Playwright-based synthetic checks, private locations
• Enterprise: Custom pricing

The free tier is generous for API monitoring. 10,000 API check runs per month is enough to check multiple endpoints every minute. The 1,500 browser check runs use Playwright under the hood, meaning Checkly can simulate a real user clicking through your signup flow or checkout process and alert you if any step breaks.

This is fundamentally different from the other tools in this list. UptimeRobot checks if your URL returns a 200. Checkly checks if your entire user flow actually works. That level of monitoring catches issues that basic uptime tools miss entirely: a login page that loads but the form submission fails, a checkout page that renders but the payment button is broken.

The "monitoring as code" approach means your checks live in a .checks directory in your repo. You can run them locally, in CI before deploying, and continuously in production. Changes to your checks go through the same code review process as your application code. For developers who think in terms of version control and CI/CD, this feels natural.

Checkly is GDPR compliant and based in Berlin. If you serve EU customers and care about data residency, that matters.

The jump from free to $64/month is steep. There is no $15 or $20 middle tier. You go from hobby to team pricing with nothing in between. For a solo indie hacker, that gap is hard to justify unless you are specifically building API-heavy products where synthetic monitoring is worth the investment.

Who should NOT use Checkly: Anyone who just needs basic "is my site up?" monitoring. Checkly is built for developers who want to monitor API endpoints and user flows programmatically. If you want to add a URL and get a Slack alert when it goes down, UptimeRobot does that for free with a simpler setup.

How to choose

You want free and simple: UptimeRobot. 50 monitors at no cost. Add a URL, pick Slack as your notification channel, done. Upgrade to Solo ($9/month) when you need 1-minute checks.

You run a VPS already: Uptime Kuma. Install it on a separate $5/month droplet and you have unlimited monitoring forever. The interface is better than most paid tools. Just make sure it runs on a different server than your production app.

You are growing past solo: Better Stack. When you need incident management, on-call scheduling, and status pages in one dashboard, Better Stack is the best integrated option. The $29/month Responder plan includes unlimited phone/SMS alerts for on-call.

You build API-heavy products: Checkly. Playwright-based browser checks and monitoring-as-code are genuine differentiators. If "does my checkout flow actually complete?" is a more important question than "is my homepage loading?", Checkly is worth the $64/month.

The practical path for most indie hackers: Start with UptimeRobot free (50 monitors). When your SaaS is earning revenue and you need faster alerts or incident management, evaluate Better Stack. If you already manage servers, skip everything and set up Uptime Kuma.

FAQ

How often should I check my endpoints?

Every 5 minutes is fine for most indie hacker projects. If you run a product where minutes of downtime cost real money (e-commerce, real-time collaboration), upgrade to 1-minute checks. Anything faster than 1 minute is typically only needed for high-traffic B2B SaaS or fintech applications.

Do I need uptime monitoring if I already use error tracking?

Yes. Error tracking tools like Sentry catch application errors inside your code. Uptime monitoring catches infrastructure problems: your server is down, your DNS is misconfigured, your SSL certificate expired, your database is unreachable. These are different failure modes. Use both.

Can I use uptime monitoring for cron jobs?

Yes. UptimeRobot, Better Stack, and Uptime Kuma all support heartbeat (or "push") monitors. Your cron job pings a URL after each run. If the ping stops arriving, you get an alert. This is how most indie hackers monitor background jobs, database backups, and scheduled tasks.

What is a status page and do I need one?

A status page (like status.yourapp.com) shows your users whether your service is up or experiencing issues. All four tools in this list offer status pages (free on UptimeRobot and Better Stack, built-in on Uptime Kuma, paid add-on on Checkly). You should set one up once you have paying customers. It reduces support tickets during outages and builds trust.

Is self-hosted monitoring reliable enough for production?

Yes, if you run it on a separate server from your production app. Uptime Kuma on a $5/month VPS in a different region than your production infrastructure gives you independent monitoring. The risk is if you run it on the same server you are monitoring. If that server goes down, your monitoring goes down with it and you learn about the outage from your users instead.

Bottom line

Uptime monitoring is the cheapest insurance you can buy for your SaaS. A $0/month UptimeRobot account or a $5/month VPS running Uptime Kuma catches outages before your users do. The cost of not knowing your site is down is always higher than the cost of monitoring it.

Start with UptimeRobot's free plan today. Add monitors for your production URL, your API, and your status page. Set up Slack notifications. That takes 5 minutes and covers 90% of what an indie hacker needs.

If you outgrow it, you will know.
