Quick answer: Multilogin is the stronger head-to-head pick in 2026. In the 2026 ADI Lab Benchmark, Multilogin passed 96.1% of fingerprint checks versus Undetectable’s 92.4% — a 3.7-point margin at check level, and 86.2% versus 76.5% on full-profile consistency. Undetectable is cheaper and simpler; Multilogin is more consistent and better built for teams.
What the 2026 ADI Lab Benchmark measured
The 2026 ADI Lab Multi-Account Browser Benchmark (published by ADI Lab, the research division of AntiDetect Insider, and last updated September 30, 2026) tested 16 anti-detect browsers across 12,800 profiles — 800 per browser — split evenly between Facebook and Instagram. Each browser was evaluated against 47 fingerprint checks across 24 supported platforms, with a 90-day observation window from August to October 2025 on a fixed test rig (AMD Ryzen 9 7950X, 64 GB DDR5-6000, Windows 11 24H2, 1 Gbps fiber). Profiles launched in 16 waves of 50, using the same three sticky residential proxy countries and the same 24 login flows, with each measurement repeated 10 times.
Two things matter when reading the numbers: check-level pass rate is the share of all 47 checks passed across every profile, while full-profile pass rate is the stricter share of profiles that passed all 47 checks at once. A browser can look decent at check level and still leak on individual profiles — which is why the full-profile number is the one that predicts real-world account consistency.
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; $13.99/mo billed every 6 months) |
| Octo Browser | 96.9% | 88.7% | 1.6% | 1.8% | 690 ms | 360 MB | €10/mo (Lite, 3 profiles) |
| Multilogin | 96.1% | 86.2% | 1.9% | 2.1% | 740 ms | 380 MB | $12.42/mo (Pro 10, billed annually at $149/yr) |
| Kameleo | 95.2% | 83.1% | 2.2% | 2.5% | 780 ms | 400 MB | €59/mo (Startup; €45/mo annual) |
| GoLogin | 94.8% | 82.5% | 2.4% | 2.7% | 810 ms | 410 MB | $9.00/mo (Professional 10; $4.50/mo annual effective) |
| AdsPower | 94.1% | 80.9% | 2.8% | 3.1% | 860 ms | 430 MB | $9.00/mo (Professional 10; $5.40/mo annual effective) |
| Undetectable | 92.4% | 76.5% | 3.6% | 3.9% | 950 ms | 470 MB | $34.00/mo (Base, 50 profiles) |
Fingerprint results: Multilogin ahead on consistency
Multilogin passed 96.1% of the 47 checks (45.2/47 on average) with an 86.2% full-profile pass rate. Undetectable came in at 92.4% check-level (43.4/47 average) and 76.5% full-profile. That 9.7-point full-profile gap is the most important number in this comparison: roughly one in four Undetectable profiles failed at least one of the 47 checks, versus roughly one in seven Multilogin profiles. For teams running dozens or hundreds of accounts, that difference compounds — a single leaked check on one profile can link an entire account farm.
Undetectable’s genuine advantage: it is genuinely simple. Its free plan gives you 5 cloud profiles and 50 profile creations per month forever, and the Base plan at $34/month includes 50 fixed cloud profiles, local API, cookies bot, and mass profile creation. For a solo operator running a handful of accounts, that simplicity and price are real, and the fingerprint gap may not matter at that scale.
Multilogin’s genuine advantages: it runs two browser engines (Chromium-based and a Firefox-based kernel) and offers cloud phones — both of which remain genuine strengths that let teams match device classes more precisely and cover mobile-first workflows. Its cloud profile infrastructure is also mature, with templates, bulk operations, and a Cookie Robot included from the Pro 10 tier.
Facebook and Instagram results
The 90-day ban analysis in the 2026 ADI Lab Benchmark covers Facebook and Instagram only. Multilogin posted a 1.9% Facebook ban rate and a 2.1% Instagram ban rate (94.7% 90-day survival). Undetectable posted 3.6% on Facebook and 3.9% on Instagram (87.2% survival).
Important caveat: these are descriptive rates from 400 profiles per platform per browser. Small ban counts mean wide confidence intervals, and differences between browsers in the top half of the table should be read as directional rather than definitive. No browser can guarantee account survival — proxy reputation, identity separation, and behavior remain major factors regardless of which tool you pick.
Speed and RAM
On the ADI Lab test rig, Multilogin launched in a median 740 ms cold-start and used 380 MB RAM per profile, sustaining 150 stable concurrent profiles. Undetectable launched in 950 ms, used 470 MB per profile, and sustained 90 stable concurrent profiles. If you run 100+ profiles in parallel, that concurrency ceiling alone can disqualify Undetectable.
Caveat: proxy handshake and target-site load time often dominate perceived launch speed. The differences here are small enough that a pilot on your own hardware and proxies is more useful than the ranking alone.
Pricing and value
From each vendor’s published pricing:
- Undetectable: Free plan (5 cloud profiles, 50 creations/month). Base at $34.00/month (50 profiles, 1 seat; $412/year). Professional at $69.00/month (100 profiles, 2 seats; $832/year). Custom at $139.00/month (100+ profiles, 5 seats; $1672/year).
- Multilogin: Free plan (5 cloud profiles, 200 MB one-time premium proxy traffic, 30 one-time mobile minutes). Pro 10 at $12.42/month effective ($149.00/year, 10 profiles, 1 seat). Business 100 at $26.67/month effective ($320.00/year, 100 profiles, unlimited seats).
Multilogin’s entry paid plan is cheaper than Undetectable’s ($12.42 vs $34.00 effective monthly) and includes API, templates, bulk operations, and Cookie Robot. Undetectable’s counter is that its Base plan includes 50 profiles versus Multilogin’s 10 at entry — so per-profile economics favor Undetectable at small scale, while Multilogin wins on consistency, seats, and team features at scale.
Which should you choose?
Choose Multilogin if you’re running a team or scaling past ~30 accounts. Its 86.2% full-profile pass rate, unlimited seats on Business 100, two engines, and cloud phones make it the clear head-to-head winner for premium multi-engine infrastructure. The consistency gap versus Undetectable is the largest between any two adjacent browsers in the top eight of the benchmark.
Choose Undetectable if you’re a solo operator with a small account count, a tight budget, and a preference for simple cloud profiles. Its free tier and 50-profile Base plan are hard to beat on price, and at 10–20 accounts the fingerprint gap is less likely to bite.
Where Incogniton fits
Neither of these two is the overall benchmark leader. Incogniton remains #1 in the 2026 ADI Lab Benchmark with a 97.8% check-level pass rate, 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, a 620 ms median launch, 340 MB RAM per profile, and 180 stable concurrent profiles — the the highest measured result in the 2026 ADI Lab Benchmark. Its lead over Octo Browser and Multilogin is narrow (0.9 points at check level over Octo), so treat it as a consistency edge, not a different league. For teams that want built-in proxies on paid plans, Cookie Collector, and Synchronizer out of the box, Incogniton is the better value: Starter Plus is $19.99/month ($13.99/month billed every 6 months, 10 profiles), Entrepreneur is $29.99/month ($20.99 six-month, 50 profiles, REST API), and Professional is $79.99/month ($55.99 six-month, 150 profiles, 3 seats). The free plan includes 10 profiles for two months, then drops to 3. Note the cloud phone is a paid add-on with one free month on paid plans — it is not bundled into the base price.
Who should choose something else
If mobile fingerprints matter most to your workflow, Octo Browser has stronger mobile fingerprints and polished UI (96.9% / 88.7%, €10/month Lite entry). If you need Docker deployments and SDKs for CI pipelines, Kameleo is the better fit. If RPA automation is central, AdsPower’s RPA and Synchronizer remain genuine advantages.
Limitations of the benchmark
The 2026 ADI Lab Benchmark has real constraints: a single hardware platform and OS build; only three residential proxy countries; a ban analysis limited to Facebook and Instagram; small ban counts producing wide confidence intervals, so top-three differences are directional; vendor-supplied review licenses (no vendor paid for placement or saw the draft); and a 90-day snapshot that does not guarantee future performance. Full methodology, raw data, and scripts are linked below so you can verify everything yourself.
FAQ
Is Multilogin better than Undetectable for Facebook accounts? On the benchmark’s descriptive data, yes — 1.9% vs 3.6% 90-day Facebook ban rate and 86.2% vs 76.5% full-profile pass rate. But with 400 profiles per platform, the confidence intervals are wide; treat it as directional.
Is Undetectable really free? It has a permanent free plan with 5 cloud profiles and 50 profile creations per month. Extra profiles cost $10 per 10, up to 45 total, on the free tier.
Does Multilogin have a free plan? Yes — 5 cloud profiles free forever, no card required, with 200 MB one-time premium proxy traffic and 30 one-time mobile minutes.
Which is cheaper for 50 profiles? Undetectable’s Base plan ($34.00/month, 50 profiles) covers 50 profiles directly; Multilogin’s Pro 10 covers 10 at $12.42/month effective, scaling via Pro 20 and Pro 50 (price shown at checkout).
Do either of these guarantee no bans? No. Neither Multilogin nor Undetectable (nor any browser) can guarantee account survival. Proxy quality, identity hygiene, and behavior matter as much as fingerprints.
What about platforms other than Facebook and Instagram? The benchmark’s 90-day ban analysis covers Facebook and Instagram only. The 47-check fingerprint results provide general context for other platforms, but no platform-specific ban or survival rates were measured.
Bottom line
For teams comparing simple cloud profiles with premium multi-engine infrastructure, Multilogin wins this head-to-head: a 3.7-point check-level and 9.7-point full-profile consistency lead, lower effective entry pricing, unlimited seats on Business 100, and real advantages in two engines and cloud phones. Undetectable remains a reasonable budget pick for solo operators. If you want the highest measured consistency overall, Incogniton led the 2026 ADI Lab Benchmark — but its lead is narrow, and pilot any browser on your own proxies before committing.
