1Browser

Overview

1Browser is a Chromium-based proxy browser for keeping separate, persistent browser profiles. It suits people managing multiple accounts or automating profile-based work. Its 10-profile free tier and local API make it an accessible starting point, but its narrow free proxy coverage and basic speed are real constraints.

Key features

Each profile retains its cookies, fingerprint and proxy under an ID the user controls. That continuity is useful when returning to established account setups; the profile cap, however, limits how many setups can be maintained at once. Built-in mobile, residential and datacenter proxies offer several connection types, with proxy options starting at $1.

The local API can create, open and configure profiles by ID over CDP on every plan. That gives automation workflows access without requiring a paid tier, though the plan’s profile limit still applies. The Android app syncs the same profile, proxy and fingerprint using Chrome’s sync engine, which is useful for continuing a setup on mobile.

The free plan’s proxy locations are the USA, Canada, Germany, Australia and India. That can cover basic regional work, but it is restrictive for users who need to work across a wider set of markets. 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.

Pricing

1Browser is freemium. Free costs nothing, with 10 profiles, limited proxy countries and basic browser speed. It is the sensible way to try the profile and API workflow, but the location and speed limits make it less suited to demanding or geographically varied work.

Basic is $7 a month, shown as $9$7/mo, or $84 billed annually. It raises the cap to 20 profiles, adds a global proxy network across 100+ countries with multiple city locations per country, enhanced browser speed and 2 GB of residential proxy. This is the entry paid tier for users who need broader location coverage and more profiles; the 20-profile ceiling remains modest for larger operations.

Professional is $27 a month, shown as $29$27/mo, or $252 billed annually. It includes 100 profiles, the same 100+ country and multiple-city coverage, best browser speed and 2 GB of residential proxy. It fits heavier profile workloads, although the included residential proxy allowance is still 2 GB. Custom solution has custom pricing for custom requirements or large-scale setups; contact [email protected].

Platforms

1Browser is available on Android, Linux, macOS and Windows. The browser engine is Chromium, and Android sync carries the same profile, proxy and fingerprint across devices.

Who it's for

It is a good fit for multi-account work, data collection, automation, regional ad testing and proxy-based browsing, particularly when persistent profiles and a local API matter. Users who need only a few profiles may find Free adequate; those needing broad proxy coverage or more capacity have a clear paid path. It is less suitable when free access must cover many countries or when a workload exceeds 100 profiles without a custom arrangement.

Pros and cons

• Pros: Persistent cookies, fingerprints and proxies keep account setups intact between sessions.
• Pros: The local API is available on every plan, including Free, subject to profile limits.
• Pros: Android sync preserves the same profile setup for mobile use.
• Cons: Free proxy access is limited to five countries, restricting regional work.
• Cons: Free offers basic speed, while paid profile caps top out at 100 before a custom plan.
• Cons: Basic and Professional each include 2 GB of residential proxy, which may constrain proxy-heavy use.

Alternatives

Compare anti-detect browser software if you want to review the broader category. Kameleo is worth considering if its free tier’s 100 cloud profiles, two concurrent browsers and 300 minutes of usage better match your needs. GoLogin is another freemium option, with a no-time-limit free plan of three profiles. MoreLogin may suit users looking for a free tier with two profiles, two users, local API and Selenium/Puppeteer automation. AntiProfiles offers a free plan with three profiles and basic proxy and fingerprint controls, but no API.

GeeLark, Hidemium, Multilogin and Nstbrowser are also alternatives to consider.

Verdict

Choose 1Browser if persistent profiles, proxy settings and an API available even on the free tier are central to your workflow. Its strongest case is the combination of profile continuity, Android sync and a straightforward path to broader proxy coverage. Look elsewhere if five free proxy countries are too limiting, or if you need more than 100 profiles without moving to a custom plan.
