1Browser

Overview

1Browser is a Chromium browser for keeping multi-account sessions in separate profiles, each tied to its own proxy and fingerprint. It suits people who need those setups to persist across sessions, especially for account work, regional ad checks, data collection or automation. Its free tier is a workable entry point, but its limited proxy locations and basic speed make it less compelling for sustained or location-sensitive work.

Key features

Profiles retain their cookies, fingerprint and proxy under an ID the user controls. That makes it easier to reopen a specific account setup without reconstructing its browser state. The trade-off is that profile capacity depends on the plan, so frequent parallel work may push users toward a paid tier.

Built-in mobile, residential and datacenter proxy options give users a choice of connection type, with proxy options starting at $1. The free plan, however, limits proxy countries to the USA, Canada, Germany, Australia and India. For work that depends on other regions, the free tier is a constrained preview rather than a complete solution.

A local API can create, open and configure profiles by ID over CDP on every plan, subject to that plan’s profile limit. That is useful for automation without requiring a paid subscription just to access the API. On Android, the app syncs the same profile, proxy and fingerprint through Chrome’s sync engine, making it possible to continue a profile on mobile.

The maker says data is encrypted before leaving the computer and on its AWS servers, and that it does not store browsing logs or track destinations. Its privacy policy says registration collects a name and email and that passwords are encrypted and stored on servers. These are useful privacy commitments, though account registration still involves storing personal and credential data.

Pricing

1Browser is freemium. The Free plan costs nothing (billed Free/mo) and includes 10 profiles, limited proxy countries and basic browser speed. It is a sensible way to try profile persistence and API automation, but the restricted locations and speed are meaningful compromises for regular use.

Basic costs $7 a month (billed $9$7/mo; $84 billed annually) and raises the limit to 20 profiles. It adds a global proxy network spanning 100+ countries, multiple city locations per country, enhanced browser speed and 2 GB of resident proxy traffic. This is the more practical tier for smaller operations that need broader regional coverage, though 20 profiles may be restrictive for larger workloads.

Professional costs $27 a month (billed $29$27/mo; $252 billed annually) and includes 100 profiles, the same 100+ country network and multiple city locations, best browser speed and 2 GB of resident proxy traffic. It fits heavier profile management where capacity and speed matter; the included resident proxy allowance remains 2 GB, so it does not scale with the larger profile count.

The Custom solution has custom pricing for custom requirements or large-scale setups; contact [email protected]. Choose it when the standard profile limits or setup do not fit, rather than assuming it includes a particular quota or seat count.

Platforms

1Browser supports Android, Linux, macOS and Windows. Chromium is its browser engine, and profile sync extends the same profile, proxy and fingerprint to Android. The product also offers cloud profile sync and API access.

Who it's for

1Browser is best for individuals or teams doing multi-account work who value persistent, individually proxied profiles and need a local API for scripted profile management. Regional ad testing and proxy-based browsing are also natural fits, particularly on a paid plan with broader country and city choices. It is less suited to users who need extensive free proxy coverage, more than 10 profiles without paying, or an included resident proxy allowance that grows with profile capacity.

Pros and cons

• Persistent, user-controlled profiles: Cookies, fingerprint and proxy stay tied to a profile ID, which supports repeatable account setups.
• API on every plan: Local CDP access enables profile automation even on Free, within the profile cap.
• Android continuity: Chrome sync carries the profile, proxy and fingerprint to the Android app.
• Free tier has real constraints: Ten profiles, five proxy countries and basic speed limit its usefulness for more demanding work.
• Proxy allowance does not rise with the top tier: Professional includes 100 profiles but still 2 GB of resident proxy traffic.

Alternatives

For a category-wide comparison, see Anti-Detect Browser Software.

Kameleo is worth considering if broader platform access matters: it supports Android, iOS, web, desktop, API and extension, and its free plan includes 100 cloud profiles, 2 emulated mobile browse.

GoLogin is another freemium option with a free trial and support for web, desktop and Android; consider it if those platform choices better match your workflow.

MoreLogin offers a free plan with 2 profiles, 2 users, Chrome and Firefox, local API and Selenium/Puppeteer automation. It may suit users who want those automation integrations and can work within the smaller profile cap.

AntiProfiles starts with 3 free profiles, basic proxy and standard fingerprint controls, but its free tier has no API. Consider it if those controls are sufficient and API access is not a requirement.

GeeLark has a free tier with 2 profiles, 30 bonus minutes and 1 seat; its Base plan starts at $5 a month with a 5-profile minimum. It is an option for users whose needs fit those profile and seat limits.

Hidemium has a free tier with 5 profiles, one device and no accounts per profile or team members. Consider it if a single-device setup with that smaller profile allowance is enough.

Multilogin offers 5 free profiles plus one-time premium proxy traffic and mobile minutes, making it an alternative for users who value those trial allowances.

Nstbrowser provides 500 free browser profiles, 30 standard profile launches per day, 3 team members and pay-as-you-go overages. It may be a better fit when a high free profile count matters more than unrestricted daily launches.

Verdict

Choose 1Browser if your work depends on persistent, individually proxied profiles and you want local API access without reserving automation for paid customers. Its strongest case is the combination of profile continuity, Android sync and broad paid proxy coverage. Look elsewhere if the free tier’s five countries and basic speed are too limiting, or if you need more than 2 GB of included resident proxy traffic alongside a large profile count.
