Ookla review
Ookla runs Speedtest, the internet speed test most people have run at least once to check a download number against what an ISP advertised. The company also owns Downdetector, RootMetrics, and Ekahau, and in 2026 it changed hands again: Accenture completed a $1.2 billion purchase of Ookla from Ziff Davis on June 17, 2026.
A renter deciding if a new provider is worth the switch, a remote worker troubleshooting a dropped video call, or an IT support desk determined to find out why one laptop lags on a network that otherwise tests fine. The real number matters because it's the evidence behind an ISP dispute, a refund request, or a router replacement decision, grounded in an actual measurement rather than how fast a page merely feels on screen.
This review covers how the Speedtest internet speed test works, what it measures, what it costs beyond the free app, how its numbers compare with rivals like Fast.com and other online speed tests, and where the ownership change leaves the product going into the rest of 2026.
Company history and the Accenture deal
Mike Apgar and Doug Suttles founded Ookla in 2006 in Seattle after Apgar left Speakeasy, the ISP where an early speed test started as an internal tool for auditing vendor connections. Suttles picked the name because he already owned the Ookla.com domain, registered years earlier for a pet cat named after a character on Thundarr the Barbarian.
Speedtest Mobile shipped in 2008, extending the browser speed test to phones. The Speedtest website originally ran on Adobe Flash, until Ookla rebuilt it in HTML5 in December 2015 and dropped the plugin Flash required.
Ziff Davis announced on March 3, 2026 that it would sell the Connectivity division, including Ookla, Downdetector, RootMetrics, and Ekahau, to Accenture for $1.2 billion in cash. The deal closed June 17, 2026. Ookla brought in $231 million in revenue for 2025, about 16 percent of Ziff Davis's total sales that year.
Who owns Ookla now?
Accenture owns Ookla today; the Ziff Davis era ended when the deal closed. The consulting firm folded Ookla into its network intelligence practice, framing the purchase around enterprise data and AI services for carriers. Ookla's Speedtest Global Index and Speedtest Intelligence products, the paid data feeds carriers and governments buy to benchmark network performance, sit closer to what Accenture is after than the free app millions of people open to test their home internet connection.
How the Speedtest internet speed test works
Ookla runs Speedtest on a network of more than 15,000 servers worldwide and reports the platform has completed over 55 billion speed tests since launch.
A Speedtest run measures download speed, upload speed, latency, jitter, and packet loss, the core metrics behind every result, in one pass, using that server network to keep each test close to the user's actual internet connection. Which server a given test uses is determined automatically by distance and current load, though the app lets a user override that choice manually.
Test duration and methodology
A test connects to a nearby server, ramps traffic up and down to find peak throughput, and after cycling through several phases finally reports the result in Mbps alongside ping in milliseconds. One independent comparison logged an average test duration of 39.6 seconds with a consistent 11 ms ping, in line with what a wired connection on a healthy network should return.
Platforms and the desktop version
The app runs on Android, iOS, Windows, and Mac, plus a browser version at the Speedtest.net website that needs no download. A Mac App Store listing gives Mac users a native desktop version, and testing over a wired Ethernet connection with that desktop version rules out Wi-Fi as a variable before anyone calls their ISP.
Extra features
Beyond the core speed test, Speedtest adds three things most rival tools don't:
- A video-specific speed test for 4K streaming, to check if a connection can sustain the throughput a streaming service needs rather than just a burst download number.
- Downdetector status data inside the same app, so a slow test result can be checked against an ISP-wide outage before anyone assumes their own Wi-Fi is the problem.
- A saved speed test history for signed-in users, useful for spotting a slow trend over months rather than relying on memory of one bad test.
Reading your results against the advertised speed
A speed test only means something next to the number an ISP advertised on the plan. If a provider promises 300 Mbps and a test consistently returns 180 Mbps on a wired connection, that gap is worth a call to the ISP rather than an assumption that internet speed test numbers just run low.
Test over both Wi-Fi and a wired connection to separate a router problem from an actual bandwidth shortfall. A wired connection that hits the advertised speed while Wi-Fi lags points at the router or its placement rather than the ISP itself. A mobile speed test complicates the picture further, since a weak cellular signal in one room reflects local conditions alongside the carrier's own network performance.
Download and upload speeds matter for different jobs. A household mostly streaming and browsing leans on download speed, while anyone uploading video, backing up files, or on frequent video calls needs upload speed to hold up too, and a plan advertised on download speed alone can leave upload thin by comparison. Running multiple tests on a few different devices, and at a few different times of day, gives a more reliable read on a home internet connection than one test alone provides.
Speedtest versus Fast.com and other speed tests
Fast.com, Netflix's speed test, measures download speed only, built around the one number that matters for streaming rather than a full network profile. Speedtest tests both directions plus latency and packet loss, information a gamer or a remote worker on video calls needs and a Netflix subscriber generally doesn't. Typing internet speed test into Google surfaces a built-in test powered by M-Lab too, a lighter alternative that skips opening a separate app or website.
Independent comparisons show Speedtest reporting higher throughput than some rival tools in the same test window, and the gap traces to differences in server selection and connection handling rather than one tool being wrong. M-Lab's test caps out around 700 Mbps, a ceiling that matters more each year as gigabit plans become common; Speedof.me instead emphasizes letting a user compare their own past results over time.
None of the major speed test tools share a single reference methodology. A result 10 to 15 percent apart between two services is common and reflects that gap in method, rather than a broken test.
What does Speedtest cost?
The core app and browser test are free, and Ookla makes money instead from advertising, the enterprise Speedtest Intelligence data business, and a small paid tier inside the consumer app.
| Tier | Price | What you get |
|---|---|---|
| Free | $0 | Unlimited speed tests, ads shown between runs, saved history with an account |
| Ad removal | $0.99 one-time | Removes ads from the app; no other change to features |
| Speedtest VPN Premium | $4.99/month | Ad removal plus unlimited VPN data, bundled rather than sold separately |
Is Speedtest accurate and trustworthy?
Speedtest is widely treated as the industry standard for measuring internet speed, and its scale, more than 15,000 servers and 55 billion completed tests, backs its reputation for accuracy better than any single review can. The FCC defines broadband as at least 100 Mbps download, and a Speedtest result is the number most ISPs and regulators cite when that threshold comes up in a dispute over a connection's real speed.
App Store reviewers regularly praise the interface, test speed, and overall reliability, calling it a great tool for the price and saying the free tier alone delivers their money's worth before any premium purchase. Enough return across version updates to count as big fans of the app rather than one-time downloads. Support for the free tier runs through help center articles rather than a live line, and VPN Premium subscribers get the same in-app support channels rather than a dedicated one.
Trust has limits worth naming. A test measures conditions at that moment: server load, local network congestion, and even which device runs the test can shift a result by a meaningful margin. Reviewers on Quora and elsewhere note that ping times under 20 ms read as excellent for gaming, but a single test showing that number doesn't guarantee it holds an hour later during a video call.
Running a speed test at different times of day, and confirming a surprising result against a second tool, catches the cases a single Speedtest run would miss, and keeps the accuracy question grounded in more than one data point.
Ookla and other mobile market intelligence tools
Ookla focuses on one job: measuring real-world network performance through consumer-run and passive tests. Three other names cover adjacent ground in the same mobile market intelligence category, and buyers researching one often need to know how they differ.
- Opensignal measures similar real-world network performance but leans on passive, crowdsourced data collected in the background rather than a test a user runs on demand.
- GSMA Intelligence and Omdia analyze carrier and device market data, subscriber counts, spectrum, and technology adoption, rather than running a network test themselves.
- Counterpoint Research covers device and technology market analysis with its own research methodology, a different job from benchmarking one connection.
A team needing network performance evidence for one connection wants Ookla or Opensignal; a team needing carrier-level market sizing wants GSMA Intelligence, Omdia, or Counterpoint Research instead.
Weaknesses and limitations
- A single speed test is a snapshot: results shift with server load, Wi-Fi congestion, and time of day.
- Speedtest's numbers don't always match what other tools report for the same internet connection, since no shared industry benchmark exists to arbitrate between them.
- The free app carries ads unless a user pays the $0.99 removal fee or subscribes to VPN Premium.
- The Accenture acquisition points company priorities toward enterprise network-intelligence data. Nothing announced so far changes the free tool, but a $1.2 billion price tag reflects the data business more than the consumer app bundled with it.
Is Ookla a good company to work for?
73 reviews, 69 percent of reviewers would recommend working there to a friend. Work-life balance rates highest at 4.1, with culture and values, and career opportunities, both at 3.7, and compensation and benefits at 3.8.
Positive reviews cite unlimited PTO and strong benefits. Recent reviews describe leadership friction since the founders left the company, with some staff saying feedback gets collected but rarely acted on. That pattern, collected mid-acquisition, is worth reading against the timing: any company changing owners twice in twelve years draws some of that commentary regardless of how the product itself performs.
Is Speedtest worth using?
For checking if an ISP delivers the internet speed on the bill, yes: Speedtest is free, fast, and the result most providers and regulators already recognize as accurate enough to settle a dispute. It remains the most recognized name in the speed test market, and anyone who wants deeper diagnostics, jitter, packet loss, a saved test history, and an ad-free run gets that for under five dollars a month through VPN Premium.
The tool works less well as a single source of truth. A buyer comparing ISPs, or a network engineer chasing an intermittent problem with an internet connection, should treat one Speedtest result as a data point, run it at different times, and check a second tool like Fast.com when a number looks off before assuming the connection itself is the problem.
FAQ
Who owns Ookla?
Accenture, since completing a $1.2 billion acquisition of Ookla from Ziff Davis on June 17, 2026.
What is the most reliable speed test site?
Speedtest by Ookla is the most widely used and cited among online speed tests, backed by a 15,000-plus server network and more than 55 billion completed tests, though no speed test tool publishes results against one shared reference standard.
Which is more accurate, Fast.com or Ookla?
Fast.com and Speedtest measure different things, so the better tool depends on the number that matters most: download alone, or the fuller profile Speedtest adds with upload, latency, jitter, and packet loss.
Is Speedtest trustworthy?
Yes, for what it measures at the moment a test runs. Results shift with server load and local network conditions, so a single speed test is a snapshot rather than a guaranteed daily number.
Does Speedtest cost money?
The core test is free. Removing ads costs $0.99 once, or $4.99 a month through Speedtest VPN Premium, which also includes unlimited VPN data.
Who founded Ookla?
Mike Apgar and Doug Suttles founded Ookla in Seattle in 2006, after Apgar left the ISP Speakeasy, where an early speed test began as an internal vendor-auditing tool.
Bottom line
Speedtest earned its place as the default internet speed test through scale: 15,000-plus servers, over 55 billion tests run, and name recognition strong enough that ISPs and regulators cite its numbers in speed disputes. The free app, the $0.99 ad removal, and the $4.99 VPN Premium tier cover most individual needs well.
Ownership is the bigger story heading into the rest of 2026. Accenture paid $1.2 billion for a business that generated 16 percent of Ziff Davis's revenue in 2025, and that price reflects the enterprise network-intelligence data Ookla sells to carriers and governments more than the free app millions of people open to check their home internet connection. Nothing has changed for anyone running a speed test today, but the product's direction over the next few years now depends on decisions Accenture hasn't made public yet.
