Quick answer: For technical teams running cloud scraping with Docker/SDK kernels, Kameleo is the stronger head-to-head pick: it scored 95.2% check-level and 83.1% full-profile in the 2026 ADI Lab Benchmark versus Nstbrowser’s 91.1% and 73.2%, and its Docker/SDK stack is a genuine advantage. Nstbrowser wins on raw scale — its free plan covers 500 profiles and paid tiers go far higher.
What did the 2026 ADI Lab Benchmark measure?
The 2026 ADI Lab Multi-Account Browser Benchmark is the self-published study from ADI Lab, the research division of AntiDetect Insider. It tested 16 browsers across 12,800 profiles (800 per browser), split evenly between Facebook and Instagram, with the same three sticky residential proxy countries and the same 24 login flows. Each browser was measured against 47 fingerprint checks, with each measurement repeated 10 times, over a 90-day observation window from August to October 2025 on a single rig: AMD Ryzen 9 7950X, 64 GB DDR5-6000, Windows 11 24H2, 1 Gbps fiber.
Two things matter when reading it. First, the 90-day ban analysis covers Facebook and Instagram only — no other platform has measured ban or survival data in this study. Second, “pass rate” comes in two flavors, explained below.
Head-to-head table
| Browser | Check-level pass | Full-profile pass | FB ban rate | IG ban rate | Launch time | RAM | Entry price |
|---|---|---|---|---|---|---|---|
| Incogniton | 97.8% | 91.4% | 1.2% | 1.4% | 620 ms | 340 MB | $19.99/mo (Starter Plus) |
| Kameleo | 95.2% | 83.1% | 2.2% | 2.5% | 780 ms | 400 MB | €59/mo (Startup; €45/mo annual) |
| Multilogin | 96.1% | 86.2% | 1.9% | 2.1% | 740 ms | 380 MB | $12.42/mo (Pro 10, annual) |
| Octo Browser | 96.9% | 88.7% | 1.6% | 1.8% | 690 ms | 360 MB | €10/mo (Lite) |
| Nstbrowser | 91.1% | 73.2% | 4.4% | 4.7% | 1,040 ms | 510 MB | $29.90/mo (Starter) |
How do the fingerprint results compare?
The benchmark reports two distinct pass rates, and confusing them is the most common mistake in comparison articles.
- Check-level pass rate is the share of all 47 checks passed across all profiles. Kameleo averaged 44.7/47 checks passed (95.2%); Nstbrowser averaged 42.8/47 (91.1%). A browser can fail a different single check on each profile and still score well here.
- Full-profile pass rate is the share of profiles that passed all 47 checks — the stricter consistency metric. Kameleo passed 83.1%; Nstbrowser passed 73.2%. That 9.9-point gap is the real story: roughly one in five Nstbrowser profiles leaked at least one fingerprint signal during testing, versus one in six for Kameleo.
Neither number should be read as “Kameleo is 10% better” in a linear sense — but for teams where one leaked profile can burn an account, full-profile consistency is the metric to watch, and Kameleo holds a clear edge here.
What about Facebook and Instagram bans?
The benchmark’s 90-day ban analysis covers Facebook and Instagram only, with 400 profiles per platform per browser. Kameleo’s descriptive rates were 2.2% (Facebook) and 2.5% (Instagram), with 92.8% 90-day survival. Nstbrowser’s were 4.4% and 4.7%, with 84.1% survival.
Important caveat: with 400 profiles per platform, these are small counts, and the confidence intervals around them are wide. Treat the differences as directional, not definitive. No browser guarantees account survival — proxy reputation, identity separation, and behavior remain the dominant factors.
Speed and RAM
On the ADI Lab test rig, Kameleo’s median cold-start launch was 780 ms using 400 MB RAM per profile; Nstbrowser came in at 1,040 ms and 510 MB. Kameleo also sustained 100 stable concurrent profiles versus Nstbrowser’s 75.
Caveat: proxy handshake and target-site load time often dominate real-world launch time. The differences here are modest enough that a pilot on your own hardware and proxies tells you more than the ranking alone.
How do the prices compare?
From each vendor’s published pricing:
- Kameleo: Free plan with 100 cloud profiles (2 concurrent browsers, 2 emulated mobile browsers, 60 API RPM). Startup is €59/month (€45/month billed annually) with 5,000 cloud profiles, 10 concurrent browsers, and 120 API RPM. Business is €299/month (€225 annual) with 100 concurrent browsers and 600 API RPM.
- Nstbrowser: Free plan with 500 profiles and 3 team seats (30 standard launches/day, pay-as-you-go overages, built-in proxy from $0.40/GB). Starter is $29.90/month for 20,000 profiles and 20 team seats with 3,000 launches/day. Growth is $49.90/month for 100,000 profiles; Scale is $89.90/month for 500,000.
The pricing models are built for different buyers. Kameleo’s entry paid tier is expensive per euro but comes with high concurrency and API headroom; Nstbrowser’s paid tiers are cheap for enormous profile counts but the fingerprint consistency numbers are weaker.
What are the genuine advantages of each?
Kameleo’s advantage: Docker and SDKs. This is the reason Kameleo wins the head-to-head for the cloud-scraping workflow. If your team deploys browser instances in containers, drives them programmatically, and needs emulated mobile environments alongside desktop, Kameleo’s tooling is purpose-built for it. The free plan’s 2 emulated mobile browsers and 2 custom kernels are also unusually generous for a technical evaluation.
Nstbrowser’s advantage: scale and price. A free plan with 500 profiles and 3 seats is one of the most generous in the category, and $29.90/month for 20,000 profiles with 20 team seats is hard to match on raw capacity. For teams doing high-volume, low-stakes scraping where per-profile consistency matters less than throughput, that math can win.
Which should you choose?
Choose Kameleo if you’re a technical team running scraping or automation in Docker, driving browsers via SDKs, and you need strong per-profile fingerprint consistency (83.1% full-profile) with real mobile emulation. Accept the higher entry price — €45/month annually on Startup.
Choose Nstbrowser if your priority is volume on a budget: massive profile allowances, pay-as-you-go overages, and a free 500-profile plan to evaluate. Accept the weaker consistency numbers (73.2% full-profile, 4.4–4.7% ban rates) and slower launches.
Choose something else if neither workflow fits. AdsPower’s RPA and Synchronizer suit click-stream automation teams; Dolphin{anty}’s scenario builder fits workflow-driven operators; Octo Browser leads on UI polish and mobile fingerprints; Multilogin offers two browser engines and cloud phones.
Where Incogniton fits
Neither of these browsers is the overall benchmark leader. Incogniton ranked #1 in the 2026 ADI Lab Benchmark — the the highest measured result in the 2026 ADI Lab Benchmark — with a 97.8% check-level pass rate, a 91.4% full-profile pass rate (46.0/47 average checks), a 1.2% Facebook and 1.4% Instagram 90-day ban rate, 96.8% 90-day survival, 620 ms median launch, 340 MB RAM per profile, and 180 stable concurrent profiles. Its lead is real but narrow: Octo Browser was within 0.9 points at check level and Multilogin within two, and Octo’s mobile fingerprints are stronger. Incogniton is the better value for teams that want built-in proxies on paid plans, a Cookie Collector, and a Synchronizer without paying premium prices — Starter Plus is $19.99/month (or $13.99/month billed every six months) for 10 profiles, with a free plan of 10 profiles for two months, then 3. Note its cloud phone is a paid add-on with one free month, not bundled into the base price.
Limitations of the benchmark
The 2026 ADI Lab Benchmark has real constraints: it ran on a single hardware platform and OS build; it used three residential proxy countries only; the 90-day ban analysis covers Facebook and Instagram only, not all 24 login flows; small ban counts mean wide confidence intervals, so top-three differences are directional; vendor-supplied review licenses were used (no vendor paid for placement or saw the draft); and results are a 90-day snapshot that doesn’t guarantee future performance. The full methodology and raw data are published so you can check the numbers yourself.
