Nurbak Review (2026): Pricing, Features & Honest Verdict

TLDR

Nurbak Watch is a Next.js-native API monitoring tool that runs inside your server, auto-discovers routes, and reports real P95 latency and per-route error rates. Setup is 5 lines, and Pro is free during the open beta. The catch is the narrow Next.js-only focus and beta maturity. Best for: Next.js developers who want server-side API monitoring. Price: Free; Pro $29/mo. Rating: 6.6/10.

What is Nurbak?

Nurbak, sold as Nurbak Watch, is API monitoring built specifically for Next.js. Most monitors ping your app from the outside and tell you whether a URL responds. Nurbak takes a different angle: it runs inside your Next.js server process and watches every API route from within. That means it sees real request traffic, measures actual latency percentiles, and catches problems that an external pinger would miss, like a slow database call that only shows up under real load or an error that returns a 200 status code.

It is made by Nurbak, a small team based in Montevideo, Uruguay. The setup is the headline: you add about 5 lines of code to instrumentation.ts, and Nurbak auto-discovers your API routes without manual configuration. From there it tracks P50, P95, and P99 latency, error rates split by 4xx and 5xx, and uptime, with checks from 4 global regions on the paid tiers. We dug into how it positions itself, and the value proposition is clear for one specific audience: people who build on Next.js and want API-level insight without wiring up a heavy observability platform.

What Are Nurbak’s Key Features?

Inside-the-server monitoring

The defining feature is that Nurbak runs within your Next.js server rather than pinging from outside. It executes real health checks every 60 seconds from inside the process, which surfaces issues external monitors cannot see. A route can return HTTP 200 while quietly failing downstream, and an outside pinger would call that healthy. Nurbak measures what is actually happening to your requests, which is the difference between knowing your site is up and knowing your API is genuinely working.

Auto-discovery and 5-line setup

Getting started is genuinely fast. You add roughly 5 lines to instrumentation.ts, with zero extra dependencies, and Nurbak automatically finds your API routes. You do not have to register each endpoint by hand the way you would with most monitors. For a solo developer or a small team, that low-friction onboarding is a real selling point, and it is the kind of detail that gets people to actually keep a monitor running instead of abandoning it. Because it hooks into the framework’s instrumentation entry point, it stays current as you add routes, so you are not constantly going back to update a list of endpoints in a dashboard. That self-maintaining quality is one of the strongest arguments for using a Next.js-native tool over a generic one.

Latency percentiles and error rates

Nurbak reports P50, P95, and P99 latency plus error rates broken out by 4xx and 5xx, per endpoint. These percentile metrics matter because an average latency hides the slow tail that frustrates real users. P95 and P99 tell you what your worst-affected requests experience. Having that per-route, from real traffic rather than synthetic pings, is the kind of visibility you normally only get from a full APM tool.

Fast multi-channel alerts

When something breaks, Nurbak sends alerts within about 10 seconds through Slack, email, or WhatsApp. Multi-region checks on the paid plans hit your app from 4 regions worldwide, so you can tell a global outage from a regional blip. WhatsApp alerting in particular is a nice touch for solo founders who live on their phone rather than a dashboard.

How Much Does Nurbak Cost?

Nurbak starts free, and Pro is $29 per month. The free plan covers 1 project, 3 endpoints, and checks every 5 minutes, which is enough for a single side project but not much more. Pro lifts that to 5 projects, 20 endpoints, 1-minute intervals, and monitoring from 4 regions. Team is $99 per month with unlimited projects, 100 endpoints, and team collaboration. Notably, Pro is currently free during the open beta, so you can use the paid tier at no cost while the product matures.

At $29 a month, Pro sits in the middle of the monitoring market. Better Stack, which bundles uptime, log management, status pages, and on-call scheduling, has a free tier with 10 monitors and Pro from around $24 a month. UptimeRobot offers cheap external uptime checks starting from a free tier. The difference is what you get: those tools do external pings, while Nurbak gives you server-side API metrics like P95 latency and per-route error rates that the others simply do not provide.

So the price question depends on what you value. If all you need is “is my site up,” cheaper or free external monitors do the job. If you specifically want inside-the-server API metrics for a Next.js app, Nurbak’s $29 is reasonable, and being free during beta makes it an easy trial. The honest caveat is that beta pricing can change, and you are betting on a young product to keep improving. It is also worth weighing the Team plan at $99 a month against running multiple Pro projects, since unlimited projects and 100 endpoints only make sense once you are monitoring several apps at once. For a single product, Pro is plenty, and the free tier is fine for a hobby project you just want a heads-up on.

Who is Nurbak Best For?

Use Nurbak if you build on Next.js and want real API-level visibility: P95 latency, per-route error rates, and problems that external pingers miss. Use it if you are an indie hacker or a small team who wants monitoring set up in 5 lines without learning an observability platform. Use it if fast alerts to Slack or WhatsApp matter to you. And use it now while Pro is free in beta, since that lowers the risk of trying it.

Skip Nurbak if you run anything other than Next.js, because the entire product is built around that framework and offers nothing for other stacks. Skip it if you need a full observability suite with status pages, log management, and on-call scheduling, since Nurbak is deliberately narrow and you would still need a second tool. And skip it if you want a proven, mature product with a long track record, because this is an early beta and its long-term direction and pricing are not yet settled.

Best Nurbak Alternatives

Better Stack

Better Stack is the closest all-in-one alternative, combining uptime monitoring, log management, status pages, and on-call scheduling. It has a free tier with 10 monitors at 3-minute intervals, and Pro starts around $24 a month. It only does external pings, so it will not give you server-side P95 latency per route the way Nurbak does. Pick Better Stack if you want a broader, more complete monitoring suite. Pick Nurbak if inside-the-server Next.js metrics are the point.

Checkly

Checkly focuses on monitoring as code, letting you define checks in your CI/CD pipeline and run synthetic and API checks programmatically. It is a strong choice for teams that want monitoring versioned alongside their app. Pick Checkly if you want code-first, pipeline-integrated monitoring across any stack. Pick Nurbak if you want zero-config auto-discovery inside a Next.js server rather than writing and maintaining check scripts.

UptimeRobot

UptimeRobot is the cheap, simple external uptime monitor with a generous free tier and inexpensive paid plans. It pings your URLs and tells you if they are down, nothing more sophisticated. Pick UptimeRobot if you just need basic, affordable up/down alerts for any site. Pick Nurbak if you need real API performance data from inside your Next.js app, which UptimeRobot does not attempt to provide.

Final Verdict: Is Nurbak Worth It?

Nurbak Watch does one thing and does it thoughtfully: it gives Next.js developers genuine API-level monitoring from inside their server, with a setup so light there is almost no excuse not to try it. The percentile latency, per-route error rates, and fast Slack or WhatsApp alerts are the kind of insight that usually requires a heavier APM tool. While Pro is free during the beta, the risk of trying it is close to zero.

It earns 6.6 out of 10 because the strengths come with real limits. It is Next.js-only, so it is irrelevant to most developers, it is still in beta with unproven longevity, and its narrow focus means you will likely still pay for a separate tool to handle status pages and logs. If you are a Next.js builder who wants server-side API visibility, try it now while Pro is free. If you need broad coverage or framework flexibility, a general-purpose tool like Better Stack is the safer bet.
