The open-source Multilogin alternative

Multilogin is a mature, team-focused anti-detect platform, now with a free plan and an API on every paid plan. It is still a closed product priced by profile count. Clearcote is engine-level, has an open build you can audit, and treats code as the main way in.

What is Multilogin?

Multilogin (Multilogin X) is one of the longest-running anti-detect browsers: a polished, GUI-first platform for teams and agencies managing many accounts. Its maintained engine is Mimic, a proprietary Chromium build (core 153 since late September 2026). The Firefox-based Stealthfox engine became legacy in January 2026: it gets no new cores and stays on core 146. It also sells Android cloud phones on real hardware, and it has strong workspace, role and sharing features, with profiles stored locally or in the cloud.

Automation has matured too. Every paid plan includes the API (50 to 100 requests a minute on the Pro plans), from the entry Pro 10 plan at $11/month (or $7.08/month billed yearly); there is an official Docker image for the launcher, Playwright connects over CDP, and headless is a start option. Since July 2026 there is also a free plan with 5 profiles, though without API access. The model is still a launcher that starts profiles for you, priced by how many profiles you keep, and the browser itself is closed.

Why teams pick Clearcote

An engine you can audit

Clearcote's open build ships every patch as readable source with reproducible builds. Multilogin's browser is a closed binary.

Code-first

launch() from Python, Node or .NET returns a normal Playwright browser, or keep a CDP endpoint running in Docker. No launcher service or profile API in between.

Identities aren't metered

Every --fingerprint seed is its own consistent machine, and there's no limit on how many you create. What the paid tier changes is how many browsers run at once.

A current engine

Clearcote's latest build is on Chromium 154, and new majors follow Chrome's releases.

When Multilogin might be the better pick

  • You're a team or agency that needs shared workspaces, roles and profile hand-offs more than a code-first workflow.
  • You need Android cloud phones alongside desktop profiles.
  • You want a polished GUI and a vendor to support it. Multilogin is mature and a category leader for that.

FAQ

Is Multilogin open source?

No. The browser is closed and proprietary, so you can't audit or rebuild the stealth. Clearcote's open build is fully open (BSD-3) and reproducible.

Does Multilogin have a free plan?

Yes, since July 2026: 5 profiles with no time limit and no card, but without API access. Paid plans start at $11/month for Pro 10 (check their pricing page for current prices). Clearcote's open build is free with no account, and its latest build is free with a GitHub sign-in for one browser at a time.

Can I automate Multilogin?

Yes. Every paid plan includes the API; you start a profile through its launcher (which can run in Docker, headless if you want) and connect Playwright, Puppeteer or Selenium to it. Clearcote skips the launcher: its SDK launches the browser directly from your code.

Does Multilogin still have a Firefox engine?

Stealthfox became a legacy engine in January 2026. It still runs, frozen on core 146 with no further updates; new work is on the Chromium-based Mimic engine.
