nPerf

nPerf measures internet connection speed, latency, browsing, streaming, and mobile signal strength through apps and a web service. Its speed tests use a worldwide network of dedicated servers to measure download speed, upload speed, and latency. Mobile apps offer separate speed, browsing, and streaming tests, save test history with locations on a map, and allow result sharing. nPerf says its mobile tests use up to two times less data than competing tests, and include a configurable data-threshold indicator. PC and Mac applications test connections up to 10 Gb/s and include speed, browsing, and video streaming tests. Free services include speed and latency tests, app navigation and streaming tests, instant comparisons, and speed and mobile coverage maps. A free account adds web dashboards, statistics, and cloud backup on servers in France. Premium costs $2 a year and adds unlimited history and CSV downloads of partial results from the last 100 tests. nPerf also offers telecom operators crowdsourced network analytics. Founded in 2014, it is headquartered in Villeurbanne, France.

nPerf offers a broad set of connection tests and a free tier, with Premium history and export options listed at $2 a year. Its terms restrict ordinary use, and readers should consider the stated data collection and use.

nPerf may suit individuals comparing connection performance across speed, browsing, and streaming tests. Its business analytics and hosting services are aimed at operators and other professional customers.

nPerf is a connection-testing service for people who want to measure speed, latency, browsing, streaming, and mobile signal strength. It suits consumers comparing network performance and organizations that need telecom analytics or server hosting support. The broad testing range is useful, though the free app retains only 10 tests and ordinary-user terms rule out professional and intensive use.

Overview

nPerf measures download speed, upload speed, and latency with its own algorithm and a worldwide network of dedicated servers. Mobile apps add separate browsing and streaming checks, plus mobile signal measurements. That wider set of checks can help users assess more than raw speed when diagnosing a connection.

Mobile test history includes locations on a map, and results can be shared. nPerf says its mobile tests use up to two times less data than competing tests; a configurable threshold indicator gives users a way to monitor test-related data use. The free history is limited to the last 10 tests on mobile and computer apps, so frequent testers who want to compare older results will need Premium.

Key features

PC and Mac applications include speed, browsing, and video streaming tests and support connections up to 10 Gb/s. That makes them suitable for checking high-capacity desktop links. Test sequences and simultaneous connections vary by platform, so users should expect some differences between devices.

For telecom operators, regulators, and private companies, nPerf Analytics provides crowdsourced network data, more than 250 KPIs, live analysis, and raw data export. This is a distinct business offering rather than a reason for ordinary users to overlook the personal-use restrictions in nPerf’s terms.

Organizations can also request free server hosting support. nPerf offers managed installation, protection, maintenance, and updates, or an on-request installation process for unmanaged servers. Hosting partners need a 64-bit Linux server in a data center with at least a 1 Gb/s symmetric connection; Debian 11 or 12 and Ubuntu 20.04 or 22.04 are recommended.

Pricing

The consumer plans include two free tiers and one paid subscription. The paid plan is $2 a year, billed one year. That is a low-cost way to keep a longer record of tests, though its export covers only partial results from the last 100 tests.

Premium renews yearly on Android unless cancelled; on iOS, a new subscription is required at expiry. Free Services is enough for occasional checks, while Enhanced Services suits account holders who want web dashboards and a French-hosted backup without paying. Premium is the fit for users who need unlimited history, but the stated CSV export is partial and capped at 100 tests.

nPerf’s business analytics and hosting support serve organizational needs; the consumer subscription prices above do not describe those services.

Platforms

nPerf supports Android, iOS, Linux, macOS, the web, and Windows. It also offers a command-line interface and hybrid deployment. The broad platform coverage helps users check connections across phones and computers, although available test sequences and simultaneous connections differ by platform.

Who it's for

nPerf is a good fit for consumers who want speed, latency, browsing, and streaming checks in one service, especially mobile users who value mapped history and result sharing. Users who test occasionally can stay on the free plan; people who revisit old results have a clear reason to consider Premium.

Its analytics and server hosting options are aimed at operators, regulators, and private companies. Hosting support requires suitable data-center hardware and a fast symmetric connection, while ordinary users are restricted to personal, private, non-collective use. The terms prohibit professional or intensive use and commercial transfer of test data without prior written consent, so nPerf’s consumer app is not the right choice for a business monitoring workflow.

Pros and cons

• Broad test coverage: Separate speed, browsing, and streaming checks give users a fuller view of connection performance than a speed reading alone.
• Useful mobile context: Mapped history, result sharing, and a configurable data threshold indicator help users interpret and manage mobile tests.
• Fast desktop support: PC and Mac apps handle connections up to 10 Gb/s.
• Short free history: The free mobile and computer apps keep only the last 10 tests, limiting comparisons over time.
• Business use is constrained: Ordinary-user terms prohibit professional or intensive use, despite nPerf’s separate organizational analytics and hosting services.
• Data use merits attention: nPerf may collect authorized location, device and operating-system details, network information, IP address, and test results. It says it markets anonymized technical data to professional customers; a non-anonymized IP address and test results may be sent only to the user’s operator for technical diagnosis. Its stated safeguards include firewalls, physical access controls, and access authorization checks.

Alternatives

Consider NetSpot if you want a free edition for personal or evaluation use on macOS or Windows, or want to compare its free trial and paid annual option. Consider PingPlotter if connection monitoring is the priority and its free tier’s one connection and 10-minute history are sufficient; its Professional Edition is $29 a month.

Verdict

nPerf is a strong choice for consumers who want several kinds of connection tests across mobile and desktop, with inexpensive Premium access to unlimited history. Its free tier covers casual checks, and its mobile mapping and data threshold tools add practical context. Look elsewhere for professional or intensive use under ordinary terms, or if you need complete CSV exports beyond the last 100 tests.
