Octo Browser vs Multilogin 2026: Which Premium Antidetect Is Worth It?

Octo Browser and Multilogin are the 2 names buyers mean when they say "premium antidetect browser," and in 2026 they've gone in different directions. Octo puts everything into its kernel: Octium 156 came out on October 22, 2 days after Chrome, and its team tools log every action. Multilogin follows Chrome by design 2 weeks later, but $40 a month buys 100 profiles with unlimited team seats and real Android phones in the cloud, about 50% less than Octo charges.

I've used Multilogin in my own work; for Octo this comparison is built on what the company publishes. Everything below was checked on October 22, 2026: pricing pages, refund terms, help centers, Octo's Octium changelog and Multilogin's release notes. For the full picture, read our Octo Browser review and Multilogin review.

Kernel: 2 days against 2 weeks

Octo is among the fastest on the market. Its dated Octium changelog shows every Chromium version in 2026 arriving 2 to 6 days after Chrome, and Octo's home page promises to update "as quickly as possible, so that no one notices any difference between Octo and Chrome sessions."

Multilogin is slower by design. Its help center says "the new Mimic core is usually released 1–2 weeks later" than Chrome, applied automatically when you launch a profile. The release notes show exactly 14 days for each of the last 3 versions.

• 153. Chrome stable: September 8. Octo Octium: September 10, 2 days. Multilogin Mimic: September 22, 14 days.
• 154. Chrome stable: September 22. Octo Octium: September 24, 2 days. Multilogin Mimic: October 6, 14 days.
• 155. Chrome stable: October 6. Octo Octium: October 8, 2 days. Multilogin Mimic: October 20, 14 days.
• 156. Chrome stable: October 20. Octo Octium: October 22, 2 days. Multilogin Mimic: not yet.

What it means. Chrome now ships every 2 weeks. Octo's profiles almost always claim the current Chrome; Multilogin's are almost always 1 version behind, which is where most of the market sits. Multilogin's upside is that you never update by hand: the new core arrives with the next launch. Its Firefox core, Stealthfox, stopped at version 146 in December 2025, so plan to move old Stealthfox profiles to Mimic.

Neither details its spoofing method. Octo says its fingerprints come from real devices with 50+ configurable parameters; Multilogin says each profile looks "like a real, distinct device." In October 2026, Check Point Research picked Multilogin, Kameleo and AdsPower for a report on AI-assisted antidetects referenced on underground forums, and Fingerprint, a company that sells device identification to websites, names Octo among its examples of antidetect browsers. Both are on detectors' radar.

Price: about 2 times apart, more with a team

Multilogin costs about 50% less for the same profiles. Monthly prices, with yearly billing in brackets:

• 10. Octo Browser: 29 EUR (21 EUR). Multilogin: $11 ($7.08).
• 100. Octo Browser: 79 EUR (56 EUR). Multilogin: $40 ($26.67).
• About 300. Octo Browser: 169 EUR for 350 (119 EUR). Multilogin: $89 for 300 ($57.08).
• About 1,000. Octo Browser: 329 EUR for 1,200 (231 EUR). Multilogin: $185 for 1,000 ($121.25).

Teams are where the gap explodes. Octo's Lite, Starter and Base plans are owner-only; Team gives 3 members plus the owner and up to 3 more at 25 tokens each, which Octo says equal 25 EUR. Multilogin's Business plans include unlimited seats, though Pro plans have only 1 or 2 and extra seats aren't sold separately.

• 3 people on about 100 profiles: 169 EUR at Octo (Team, 350 profiles), $40 at Multilogin (Business 100).
• 10 people on about 300 profiles: Octo's Team tops out at 6 members plus the owner, so you need Advanced, 329 EUR with 8 members plus the owner, plus 1 more at 20 tokens, 349 EUR. At Multilogin, Business 300 costs $89.

Trying and refunds favor Multilogin. It has a free plan with 5 cloud profiles, though they're deleted after 7 days without activity, and a 14-day money-back guarantee on paid plans. Octo has no free plan, only a 2-day Starter trial with the code TRIAL, and refunds within 5 days of the first payment: in full only if you haven't created any profiles, otherwise partly, and never for renewals.

Teams, API and automation

Octo gives more control. Access rights go down to each folder, profile, template, tag and proxy, every plan has an action log, and the API offers an audit stream. Multilogin has 4 roles (owner, manager, operator and starter) with folder-based access and profile transfer to other workspaces, but its pricing page lists "workspace activity logs" as "Soon." If you need to see who did what in a shared account today, that's Octo.

Both APIs are tight. Octo's starts on Base at 79 EUR with 50 requests a minute and 500 an hour, rising to 100 on Team and 200 on Advanced. Multilogin's starts on Pro 10 at $11 with 50 a minute, 75 on Pro 20 and 100 on Pro 50 and Business, plus a CLI. Both connect Playwright, Puppeteer and Selenium.

Neither has a no-code builder or synchronizer. Multilogin adds Cookie Robot for warming up profiles in account farming, with bulk creation and cloning, from Pro 50. We found no comparable tools in Octo's docs.

Mobile and extras

Multilogin's cloud phones are its real difference. It runs Android 10 to 16 phones on real hardware in the cloud, streamed inside the desktop app, for app-based accounts. Every paid plan includes minutes (150 a month on Business 100), extra minutes cost from $0.0067 each in bulk, and an open-source AI agent controls the phones over ADB. Its old Android browser profiles are deprecated.

Octo works on your own phone instead. On desktop it creates profiles with Android fingerprints, and its iOS and Android apps run mobile profiles on a real phone; those stay separate from desktop profiles. New users get 100 mobile profiles free during open testing. Octo has no cloud phones.

Proxies. Multilogin includes premium proxy traffic in every paid plan, 5 GB a month on Business 100. Octo sells residential and mobile proxies with UDP support in its built-in Proxy Shop.

Platforms. Octo runs on Windows including Windows Server, macOS 13 and later and several Linux distributions. Multilogin needs 64-bit Windows 10 or later, macOS 14 or later or Ubuntu 22 and later, and doesn't support Windows on ARM.

Which one should you choose?

By situation:

• Expensive accounts, kernel freshness first — Octo Browser. 2 days behind Chrome against 14.
• Team that needs an audit trail today — Octo Browser. Action log on every plan; Multilogin's is "Soon".
• Agency or team of 3 to 10+ — Multilogin. Unlimited seats from $40
• Accounts that live in Android apps — Multilogin. Cloud phones on real hardware
• Working from your own iPhone — Octo Browser. iOS app with mobile profiles.
• You want a long refund window — Multilogin. 14 days against 5.

You can also split the work: keep the most valuable accounts in the browser with the faster kernel, and the team, the volume and the phones in the one with cheaper seats. If you do, keep each account in one browser; moving a profile between vendors means a new fingerprint.
