Self-hosted uptime monitoring gives you full control over your data, infrastructure, and alerting. But as a solo SaaS builder, you don't have time to babysit a monitoring stack. You need something that works out of the box, catches failures before your users do, and doesn't require a DevOps degree to configure. In 2026, the options are better than ever—but also more confusing. Here are the five best self-hosted (or self-hostable) uptime monitoring tools, plus a clear look at where OpsMate fits for indie developers who want a middle ground between "DIY everything" and "enterprise overkill."
Why Self-Hosted Uptime Monitoring Still Matters in 2026
Cloud-hosted monitoring SaaS is convenient, but it comes with trade-offs: per-endpoint pricing, data egress costs, and the occasional "monitoring outage" that ironically blinds you to real incidents. Self-hosted tools keep your check data on your own infrastructure, which is critical if you're monitoring internal APIs, staging environments, or services behind a VPN. They also offer flat pricing (often free) and full customization.
But "self-hosted" doesn't have to mean "run my own Postgres cluster and Redis cache." The tools below range from single-binary simplicity to full-featured observability suites. The right choice depends on how much operational overhead you're willing to absorb.
The 5 Best Self-Hosted Uptime Monitoring Tools
1. Uptime Kuma
Uptime Kuma is the darling of the self-hosted community. A single Docker container gives you a polished web UI, 90+ notification integrations, and support for HTTP(S), TCP, Ping, DNS, and even game server checks. It's actively maintained, has a massive community, and stores everything in SQLite. For a solo dev, it's often the first stop.
Pros: Dead-simple install, beautiful status page builder, no external dependencies.
Cons: No built-in server metrics (CPU/RAM/disk), alerting is basic (no escalation policies), and the status page is per-project, not multi-tenant.
2. UptimeRobot (Self-Hosted Alternative: Statping-ng)
UptimeRobot is technically a SaaS, but many self-hosters use Statping-ng as its open-source replacement. Statping-ng offers HTTP, TCP, and ICMP checks, a clean dashboard, and a solid API. It's lighter than Uptime Kuma but less polished. Development has slowed, but it remains stable.
Pros: Very lightweight (Go binary), simple JSON config, good for basic uptime percentages.
Cons: Lacks SSL and keyword monitoring out of the box, UI feels dated, no built-in incident timeline.
3. Grafana + Prometheus (with Blackbox Exporter)
This is the "pro" stack. Prometheus scrapes metrics, Blackbox Exporter probes HTTP/HTTPS/TCP endpoints, and Grafana visualizes everything. You also get full server metrics (CPU, RAM, disk) from node_exporter. It's the most powerful option on this list—and the most complex.
Pros: Unlimited customization, real-time metrics, alerting via Alertmanager.
Cons: Steep learning curve, requires maintaining multiple services, no built-in status page (you'll build one in Grafana or use a separate tool).
4. Gatus
Gatus is a lesser-known gem. It's a single Go binary that does uptime checks, latency tracking, and even "conditional" checks (e.g., validate JSON responses). It has a built-in status page and can alert via Slack, Discord, and webhooks. It's faster and more configurable than Uptime Kuma, but the UI is more utilitarian.
Pros: Extremely fast, YAML-based config, great for API response validation.
Cons: No server metrics, smaller community, status page is basic (no incident timeline).
5. Cachet (with Uptime Kuma for checks)
Cachet is a dedicated status page system, not a monitor. But many self-hosters pair it with a monitor for a complete solution. However, Cachet has been largely unmaintained since 2020. I'm including it only to warn you: if you're starting fresh in 2026, skip Cachet and use a built-in status page from a modern tool.
Better alternative: Use Uptime Kuma's built-in status page or OpsMate's status page generator (more on that below).
Feature Comparison Table
| Feature | OpsMate | Uptime Kuma | Statping-ng | Prometheus + Grafana | Gatus |
|---|---|---|---|---|---|
| Monitoring Types | HTTP/HTTPS, SSL cert, keyword | HTTP, TCP, Ping, DNS, game | HTTP, TCP, ICMP | HTTP/HTTPS (Blackbox), custom | HTTP, TCP, ICMP, DNS, conditional |
| Free Tier | 1 website + 1 server check | Unlimited (self-hosted) | Unlimited (self-hosted) | Free (self-hosted) | Free (self-hosted) |
| Server Metrics | Yes (CPU, RAM, disk) | No | No | Yes (node_exporter) | No |
| Alerting | Slack, webhooks, daily email digest | 90+ integrations | Slack, email | Alertmanager (Slack, email, etc.) | Slack, Discord, webhooks |
| Starting Price | $9/month (paid) | Free (self-host) | Free (self-host) | Free (self-host) | Free (self-host) |
| Solo-Dev Friendliness | High (zero-config, cloud-managed) | High (Docker one-liner) | Medium (config file) | Low (multi-service setup) | Medium (YAML config) |
Pricing Breakdown
- OpsMate: Free tier covers 1 website + 1 server check. Paid plans start at $9/month for up to 5 servers. Includes SSL, keyword monitoring, and server metrics in all paid tiers. No hidden per-endpoint fees.
- Uptime Kuma: Free forever. You pay only for the server it runs on (e.g., $5/month VPS). But you'll likely need a separate tool (like Netdata) for server metrics—another service to maintain.
- Statping-ng: Free. Same hosting cost as Uptime Kuma. No ongoing license fees.
- Prometheus + Grafana: Free software, but hosting can get expensive if you store long-term metrics. You'll spend time (and money) on storage, retention policies, and HA setups.
- Gatus: Free. Runs on a single small VPS. No server metrics means you'll need a second tool.
Hidden costs to consider: Time is money. Self-hosting Uptime Kuma, for example, means you're responsible for updates, backups, and security patches. If your monitoring tool goes down, you're flying blind. OpsMate's paid plan removes that operational burden while still letting you keep your checks pointed at self-hosted endpoints.
Ease of Setup
- OpsMate: Sign up, add your website URL and server IP, done. No Docker, no YAML, no database. Alerts configured in under 5 minutes. The built-in status page is generated automatically from your monitors.
-
Uptime Kuma: Very easy if you're comfortable with Docker.
docker run -p 3001:3001 louislam/uptime-kumaand you're live. But you need to handle reverse proxy, SSL, and persistence yourself. - Statping-ng: Requires a binary download and a config file. Doable, but the lack of a web-based setup wizard makes it less friendly.
- Prometheus + Grafana: The hardest. You need to configure Prometheus scrape targets, Blackbox exporter modules, Alertmanager routing, and Grafana datasources. Expect a full afternoon of work—and ongoing maintenance.
- Gatus: Easy if you like YAML. Write a config file, run the binary, done. But you'll need to learn Gatus's specific syntax.
Verdict: For a solo builder who wants to ship features, not monitor the monitor, OpsMate wins on setup speed. If you enjoy tinkering, Uptime Kuma is a close second.
When to Pick Each Tool
Pick Uptime Kuma if: You want a free, self-hosted solution with a friendly UI and don't mind maintaining a Docker container. You're okay with separate tools for server metrics and don't need SSL or keyword checks (you'll need to script those yourself).
Pick Statping-ng if: You want a minimal, low-resource binary for basic uptime checks and have a simple, static infrastructure. Be prepared for a less polished experience.
Pick Prometheus + Grafana if: You're already using Prometheus for application metrics, or you need advanced alerting rules and long-term trend analysis. This is for the "infrastructure as code" mindset.
Pick Gatus if: You need fast, conditional API checks (e.g., verify a JSON field equals a value) and want a single binary with a built-in status page. You're comfortable with YAML.
Pick OpsMate if: You want self-hosted-level visibility (server metrics, SSL, keyword) without the self-hosted maintenance. You're a solo SaaS founder who wants alerts in Slack and a status page that updates itself. The free tier is perfect for a single-site launch; the $9/month plan covers a small server fleet.
Conclusion
Self-hosted uptime monitoring is a spectrum. On one end, you have Uptime Kuma's "just run Docker" simplicity. On the other, you have Prometheus's full observability stack. Both are valid—but both require you to own the operational burden. As a solo developer, your scarcest resource is attention. Every hour spent patching your monitoring tool is an hour not spent on your product.
OpsMate isn't trying to replace Uptime Kuma or Prometheus. It's for the builder who wants uptime checks, server metrics, SSL monitoring, and a status page in one place, without running a mini data center. The free tier gets you started, and the paid plan is a no-brainer if you value your time more than a $9/month subscription. Try the free tier, see if it fits your workflow, and if it doesn't, you've lost nothing but a few minutes of setup. That's the kind of low-risk trial every indie dev can appreciate.
