UptimeRobot Alternative
Go beyond basic up/down checks. Monitor your APIs from 4 global regions with DNS, TLS, TTFB, and P95 latency tracking.
UptimeRobot is one of the most popular uptime monitoring tools available, and for good reason. It offers a generous free tier with up to 50 monitors, a clean dashboard, and reliable alerting that has helped millions of developers and site owners keep tabs on their services since 2010. For straightforward "is my site up?" checks, UptimeRobot remains a solid and well-trusted choice.
However, as APIs become more complex and teams adopt distributed architectures, many developers find that basic HTTP pings from a single region no longer tell the full story. You might need to know how your API performs across continents, whether your TLS handshake is slowing things down, or what your P95 latency looks like over the past week. UptimeRobot's metrics are limited to response time and up/down status, which can leave blind spots when diagnosing real-world performance issues.
Nurbak was built for developers who need that deeper visibility. With health checks running from four global regions, granular metrics covering DNS resolution, TLS negotiation, time to first byte, and response size, plus encrypted credential storage and flexible alert channels, Nurbak gives you the observability layer your APIs deserve.
| Feature | UptimeRobot | Nurbak |
|---|---|---|
| Check Regions | Single region (US or EU) | 4 regions (US, BR, FR, JP) |
| Check Frequency (Free) | Every 5 minutes | Every 5 minutes (1-min on Pro) |
| Performance Metrics | Response time + up/down only | DNS, TLS, TTFB, response size, total time |
| Credential Encryption | Basic storage | AES-256 + AWS KMS |
| Alert Channels | Email, SMS, Slack, webhooks | Slack, WhatsApp, SMS, email |
| Public Status Pages | Yes (paid plans) | Yes (included in free tier) |
| Latency Percentiles | Average only | P50, P95, P99 tracking |
| Free Tier | 50 monitors, 5-min intervals | Generous free tier with multi-region checks |
UptimeRobot pings your endpoint from a single location, which means you only see performance from one perspective. Nurbak runs health checks simultaneously from the US, Brazil, France, and Japan, giving you a true global picture of your API's availability and latency. If your service is slow in South America but fast in Europe, you will know immediately instead of guessing.
Knowing your API is 'up' is table stakes. Nurbak breaks down every request into DNS resolution time, TLS handshake duration, time to first byte, and response payload size. Combined with P95 latency tracking, you can identify exactly where bottlenecks occur, whether it is a slow DNS provider, an expiring certificate causing negotiation delays, or a bloated response body.
Monitoring authenticated endpoints means storing API keys and tokens somewhere. UptimeRobot stores these as part of your monitor configuration, while Nurbak encrypts all credentials at rest using AES-256 with keys managed through AWS KMS. This gives you a meaningful security layer when monitoring private or internal APIs that require bearer tokens, API keys, or basic auth credentials.
UptimeRobot is a reliable and well-established monitoring tool, and it works great for basic uptime checks. The reason developers consider switching is when they need deeper metrics that go beyond simple up/down status. If you want to track DNS resolution time, TLS handshake performance, TTFB, or P95 latency across multiple global regions, Nurbak provides that level of detail out of the box. It is not about UptimeRobot being bad, it is about needing more observability as your APIs grow.
UptimeRobot's free tier is genuinely generous with 50 monitors, and that is one of its strongest selling points. Nurbak's free tier focuses on providing richer data per monitor rather than maximizing monitor count. Each Nurbak monitor gives you multi-region checks, detailed performance breakdowns, and P95 latency tracking, which means fewer monitors can deliver more actionable insights than a larger number of basic ping checks.
Nurbak can monitor any HTTP or HTTPS endpoint, whether it is a website homepage, a REST API, a GraphQL endpoint, or a health check route. The detailed metrics like DNS, TLS, and TTFB are valuable for any web service. That said, Nurbak is specifically designed with API developers in mind, so features like authenticated endpoint monitoring with encrypted credential storage and structured response validation are where it particularly shines.
If you serve users globally, a single-region check can miss problems that affect specific geographies. For example, a CDN misconfiguration might make your API fast in the US but slow in Asia. A DNS propagation issue might only affect South American users. Nurbak checks from the US, Brazil, France, and Japan simultaneously, so you catch these regional issues as they happen rather than waiting for user complaints to trickle in.
