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

TLDR

CubeAPM is an OpenTelemetry-native observability platform that runs inside your own cloud instead of a vendor’s. It fixes the two things teams hate about Datadog: unpredictable bills and data leaving your VPC. Best for: mid-size and enterprise engineering teams escaping per-host APM bills. Price: from $0.20/GB ingested, no free plan. Rating: 8.1/10

What is CubeAPM?

CubeAPM is a full-stack observability and application performance monitoring platform. It covers APM and distributed tracing, log management, infrastructure monitoring, real user monitoring, synthetic monitoring, error tracking and Kubernetes monitoring in one product. The pitch is unusual: instead of shipping your telemetry to a SaaS vendor, CubeAPM deploys inside your VPC or on-prem, and the CubeAPM team manages the deployment for you. The company calls this “self-hosted but managed.”

That positioning exists because of a real gap. Cloud SaaS observability is easy to run but expensive and it moves your production data offsite. Rolling your own ELK or Prometheus stack keeps data local but hands your platform team a permanent second job. CubeAPM sits between those two. It is built natively on OpenTelemetry rather than a proprietary agent format, which means the instrumentation you write is portable if you ever leave. The company publishes case studies with Indian logistics and travel businesses including Delhivery and RedBus, and it holds SOC 2 and ISO 27001 certifications. We dug into it as a Datadog replacement, and that is the frame that makes the most sense.

What Are CubeAPM’s Key Features?

Managed deployment inside your own cloud

This is the whole product in one line. CubeAPM installs in your AWS, GCP, Azure or on-prem environment, so traces, logs and metrics never leave your network boundary. Upgrades, patches and day-two operations are handled by the CubeAPM team rather than your platform engineers. The practical payoff is compliance: if you operate under data localisation rules, this removes the argument entirely. The secondary payoff is cost, because egress charges on telemetry data drop to nothing when the data never exits your cloud.

OpenTelemetry-native ingestion

CubeAPM ingests OpenTelemetry data directly rather than wrapping it in a proprietary agent. It also accepts existing New Relic and Datadog agent traffic, which is the detail that makes migration realistic. You point your existing agents at CubeAPM instead of re-instrumenting hundreds of services. The company claims most teams complete a switch in under an hour. We would treat that as a best case rather than a promise, but the agent compatibility is genuine and it is the single biggest reason a migration here is less painful than usual.

AI-based smart sampling

Trace volume is what kills observability budgets. CubeAPM applies sampling that keeps error traces and slow outliers while discarding redundant healthy traces, and the company states this cuts storage by up to 95 percent. Sampling is always a trade-off, and you should test it against your own traffic shape before believing any vendor number. But the design intent is right: you pay for the traces that tell you something, not the thousands that confirm your checkout endpoint returned 200 again.

Unlimited retention on Enterprise

Long retention is where SaaS observability gets brutally expensive, because you are renting someone else’s storage at a markup. Because CubeAPM writes to your own storage, the Enterprise tier offers unlimited retention rather than a 15 or 30 day window. You still pay for the underlying disk, quoted at roughly $0.02/GB for compute and storage, but that is your cloud provider’s rate, not a monitoring vendor’s. For anyone who has needed a log line from four months ago during an incident review, this matters more than it sounds.

How Much Does CubeAPM Cost?

CubeAPM’s Pro plan starts at $0.20/GB per month of data ingested, billed pay-as-you-go. Data transfer is quoted at $0.01/GB and the infrastructure layer, compute plus storage, at roughly $0.02/GB. Pro includes APM, log management, infrastructure monitoring, real user monitoring, synthetic monitoring, error tracking, service graphs, basic alerting, SLOs, high availability clustering, SSO, MFA, audit logs and email support, with 15 days of data retention. Enterprise is custom priced and billed annually, adding distributed tracing depth, continuous profiling, runtime metrics, custom metrics and dashboards, role based access control, a dedicated account rep and unlimited retention.

The number that actually moves the needle is not the per-GB rate. It is that user licences are free. Datadog APM runs $31 per host per month on an annual Pro contract, and standalone APM tiers reach $36 to $47 per host. New Relic gives you 100GB of ingest free then charges $0.40/GB, but full platform user seats start around $99 per user per month and climb sharply. On both platforms, adding engineers to the dashboard adds to the invoice. CubeAPM does not charge per seat at all, so a 40 person engineering team costs the same to onboard as a 4 person one.

There is no free tier. You get a sandbox to try and then a demo call, which is a real friction point if you wanted to run a quiet weekend evaluation without talking to sales. Compared to SigNoz, which starts at $49/month including $49 of usage at $0.30/GB for logs and traces, CubeAPM’s $0.20/GB is cheaper per gigabyte but has no published entry point for a solo developer. This is priced and sold for teams with a real telemetry bill already.

Who is CubeAPM Best For?

Use CubeAPM if your Datadog or New Relic invoice has become a line item that finance asks about. The savings case is strongest at volume, where per-host and per-seat charges compound and long retention is non-negotiable. It is also the obvious pick if you operate under data residency rules, in regulated sectors, or in markets where telemetry cannot legally leave the country. Teams already instrumented with OpenTelemetry will have the easiest migration of anyone.

Use CubeAPM if you want managed observability without vendor lock-in. Because ingestion is OpenTelemetry-native, your instrumentation stays portable.

• Skip CubeAPM if you are a solo developer or a small startup. There is no free tier and no self-serve entry point, and the deployment model assumes you have cloud infrastructure to run it on.
• Skip it if you need the deepest ecosystem of prebuilt integrations. Datadog’s integration catalogue is a decade ahead and that gap is real.
• Skip it if you want to evaluate without a sales conversation. The sandbox helps, but full onboarding runs through a demo.
• Skip it if your team has no appetite for anything running in your own cloud account, even when someone else operates it.

Best CubeAPM Alternatives

SigNoz

SigNoz is the closest philosophical match: OpenTelemetry-native, open source, and available either self-hosted for free or as a cloud service. The Teams plan starts at $49/month including $49 of usage, with logs and traces at $0.30/GB and metrics at $0.10 per million samples, both on 15 day retention. Early-stage startups can qualify for $19/month for the first year. SigNoz wins on accessibility, because you can install the community edition tonight without talking to anyone. CubeAPM wins on the managed-inside-your-cloud model, where SigNoz self-hosting still leaves the operations burden with you.

Datadog

Datadog remains the category leader and the integration ecosystem is genuinely unmatched. APM starts at $31 per host per month on annual Pro billing, with infrastructure monitoring from around $15 to $27 per host and logs from $0.10/GB, and the add-ons stack fast. If your priority is breadth of coverage and you can absorb the cost, Datadog is still the safest technical choice. If your priority is a predictable bill and keeping production data in your own network, it is exactly the thing CubeAPM was built to replace.

New Relic

New Relic’s consumption model is friendlier at small scale: 100GB of ingest free every month, then $0.40/GB, or $0.60/GB on Data Plus. The catch is seats. Full platform users are priced per head and typically start near $99 per user per month, so cost scales with headcount as much as with data. For a five person team sending moderate volume, New Relic is a reasonable landing spot. For a 50 engineer organisation, the seat maths is what pushes teams toward CubeAPM’s free-licence model in the first place.

Final Verdict: Is CubeAPM Worth It?

CubeAPM is a sharp answer to a specific, expensive problem. If you are paying per host and per seat for observability, and your compliance team is nervous about production traces sitting in another company’s cloud, this removes both problems at once. The $0.20/GB rate with free user licences is the strongest part of the offer, and OpenTelemetry-native ingestion means you are not signing up for another decade of proprietary agents. Agent compatibility with Datadog and New Relic makes the migration path credible rather than theoretical.

The reservations are about maturity and access, not capability. There is no free tier, evaluation runs through a demo, and the third-party review footprint is still thin compared with the incumbents, so you are relying more on your own proof of concept than on a wall of public reviews. Do the trial properly, test the sampling against your real traffic, and confirm the retention maths on your own storage costs. We rate it 8.1 out of 10: an excellent fit for mid-size and larger teams with a painful monitoring bill, and the wrong tool entirely for a solo developer who just wants a dashboard by lunchtime.
