Looking for Multilogin alternatives?

The open-source answer to Multilogin: the profile manager, local API and sync server are AGPL-3.0 on GitHub, and every profile stays on your machine. Every claim about Multilogin on this page was read from its own site on August 6, 2026 and links back to it. Moving across is a Chromium profile import rather than a format conversion, and the reasons not to switch have a section of their own further down.

AGPL-3.0

The question behind "Multilogin alternative" is almost never which product has the longer feature list. It is whether the accounts you have already warmed up survive the move, and how long the move takes. So this page starts there, and gets to the comparison afterwards.

Donut Browser is a desktop app that keeps every profile as a directory on your own machine. Nothing counts those directories, there is no workspace in somebody else's cloud to sign into, and the app — profile manager, local REST API, MCP server and sync server — is published under AGPL-3.0 on GitHub. The Wayfern Chromium engine it drives is proprietary, which is stated here for the same reason as everything else on this page: so you can check it.

What follows: how the import works, what survives it and what does not, 7 axes where the two products are built on different assumptions, what the free tier covers, and 4 honest reasons to stay exactly where you are.

Key Takeaways

  • Nothing converts Multilogin profiles into Donut profiles, because no antidetect vendor exports to another's format. What Donut imports is a Chromium profile directory — a folder, a browser user-data directory or a ZIP, auto-detected from Chrome, Brave, Edge, Opera, Vivaldi, Arc or Yandex — and importing is free on every tier.
  • The Donut Browser app is AGPL-3.0 on GitHub: profile manager, local REST API, MCP server and sync server. The Wayfern Chromium engine is proprietary, and this page says so rather than rounding it up to "open source".
  • The comparison below runs 7 axes, and every Multilogin cell carries the URL it was read from and the date it was read — August 6, 2026. Nothing about Multilogin is quoted from memory.
  • Your workflow depends on Android. Multilogin sells Android cloud devices; Donut Browser has no mobile or cloud-phone product.

How do you move your profiles from Multilogin to Donut Browser?

In one pass, and it is the same pass whether you hold five profiles or five hundred. Point the importer at a folder, a browser user-data directory or a ZIP archive; rename, group and attach proxies while the copy runs; each profile arrives with a freshly generated fingerprint.

Multilogin also offers Firefox-engine profiles. Those cannot be converted to a Chromium engine — migrate their cookies over the API instead.

The middle column is one pass, not five steps you run separately: detection, renaming, grouping and proxy assignment all happen while the copy runs, and the import proceeds per item so a single broken profile never aborts the batch. What arrives on the right is a Chromium profile carrying its cookies, history, extensions state and local storage — and a fingerprint that was generated on arrival.

Nothing imports a Multilogin profile directly — no anti-detect vendor exports to another's format. What Donut does import, in bulk and free on every tier, is Chromium-family profiles from Chrome, Brave, Edge, Opera, Vivaldi, Arc and Yandex, with per-profile proxy assignment applied during the import.

  1. In the app

    Open Import from the rail. Auto-detect scans the default locations of every supported Chromium-family browser and lists what it finds; Manual points at any path, including a ZIP. Imports run per item, so one broken profile never aborts the batch.

  2. Over the REST API

    Three endpoints cover the whole migration on the local API at 127.0.0.1:10108 — list what is importable, bulk-import with a group and a per-item proxy, and bulk-add proxies from a plain-text list or a Donut export.

  3. Through MCP

    The MCP server exposes the same surface as tools, so an assistant can run the migration conversationally: detect the profiles, import them into a group, assign your stored proxies round-robin.

What comes across in a profile import, and what does not?

This is the part a switching guide usually skips. An import is not a clone: some of the profile travels, one part of it is deliberately regenerated, and one category cannot travel at all.

Comes across

  • History, cookies, extensions state and local storage, per profile.
  • Whatever you assign during the pass: a new name, a group, and a proxy — one for every profile, or round-robin across the proxies you already have stored.
  • Your choice of what happens to a name that already exists: rename it automatically, or skip it.

Does not come across

  • Multilogin's own profile format. What you point Donut at is a Chromium profile directory — Multilogin's export if it produces one, or the browser the profile came from underneath it.
  • The old fingerprint. Every imported profile gets a freshly generated one, which is the intended behaviour rather than a shortcoming: a fingerprint already seen alongside another vendor's stack is not an asset worth keeping.
  • Firefox and Gecko profiles. They cannot be converted to a Chromium engine at all; their cookies can be migrated over the API instead.

Two prerequisites, both small: a Wayfern version has to be downloaded already, because the import path never downloads a browser, and setting a fingerprint's operating system for cross-OS spoofing is a paid feature. Everything else about importing is free.

Where does this Multilogin alternative take a different approach?

Not a feature matrix. The axes below are the ones where the two products are built on different assumptions, and every Multilogin cell restates something published on its own site, read on August 6, 2026 and linked in the sources list underneath.

  • Source code

    Donut Browser

    The app — profile manager, local REST API, MCP server and sync service — is AGPL-3.0 on GitHub. The Wayfern Chromium engine is proprietary, and the site says so.

    Multilogin

    No open-source licence and no source repository are named on the homepage or the pricing page. [1]

  • Free tier

    Donut Browser

    Unlimited local profiles, per-profile proxy and WireGuard, the profile-management API and the MCP server. No account, no card, no trial clock.

    Multilogin

    Five profiles, free with no time limit and no card, once you have created an account. [2]

  • What you are charged for

    Donut Browser

    Profiles are directories on your own disk. Nothing counts them, so the ceiling is storage rather than a plan.

    Multilogin

    Profiles and seats together: the Pro tiers are sold at 10, 50 and 100 profiles, and the Business tiers run from 300 to 10,000. [3]

  • Team seats

    Donut Browser

    Two seats included on the Team plan, priced as an add-on beyond that. Seat count never gates the profile count.

    Multilogin

    Seats are a tier feature: the Pro plans list one, two and five seats respectively, and unlimited seats begin at the Business tiers. [4]

  • Browser engines

    Donut Browser

    One engine, Wayfern: an anti-detect Chromium whose fingerprint spoofing is enforced in C++ and exposed over custom CDP commands.

    Multilogin

    Two engines, which the vendor names Mimic and Stealthfox. [5]

  • Automation

    Donut Browser

    A local REST API on 127.0.0.1:10108 (base path /v1, OpenAPI at /openapi.json) and an MCP server at /mcp, both on the free tier.

    Multilogin

    A documented hosted API, with the site naming ADB, Selenium, Puppeteer and Playwright as supported automation tools. [6]

  • Where profiles live

    Donut Browser

    Profiles, cookies and logins stay on the device. Cloud sync is an opt-in paid feature, and the personal sync server is open source and self-hostable.

    Multilogin

    An account-bound workspace at app.multilogin.com; the site does not describe a local-only mode. [7]

How much does this Multilogin alternative cost?

The free tier is not a trial and it is not capped by profile count, because there is nothing to cap: profiles are directories on your disk. The paid tiers buy capabilities, never permission to create more of them.

Free, no account

  • Unlimited local profiles on the Wayfern anti-detect Chromium engine
  • Per-profile proxy — HTTP, HTTPS, SOCKS4, SOCKS5 — and WireGuard VPN
  • The profile-management REST API and the MCP server
  • Cookie and extension management
  • Importing, which is free on every tier including this one

Paid, from $29/month

  • Cloud profile backups and the nightly Cookie Bot
  • Fingerprints for other operating systems
  • The browser-manipulation API and MCP, and a higher automation rate limit
  • Team seats, profile sharing and collaboration
  • Commercial use

When is Multilogin still the better tool?

Every switching page should carry this section and almost none do. Nothing below is softened: each one is a real limitation of Donut Browser, and where the Multilogin side of it needed a source, it has one.

  • Your workflow depends on Android. Multilogin sells Android cloud devices; Donut Browser has no mobile or cloud-phone product. [8]

  • You need Firefox-engine profiles. Donut Browser ships one engine, the Wayfern anti-detect Chromium, and imports only Chromium-family profiles.

  • You want to open the same profile from any machine with nothing to set up. Donut keeps profiles on the device; reaching them elsewhere means the paid sync tier or self-hosting the sync server.

  • You need unlimited seats on one invoice. Donut's Team plan bundles two seats and charges per seat above that, so a large team is not automatically cheaper here.

If none of those describe your work, the switch is one import and an afternoon. If one of them does, stay where you are — a browser you have to fight costs more than a subscription does.

Multilogin alternative: common questions

Is there an open source Multilogin alternative?

The Donut Browser app is published under AGPL-3.0 on GitHub: the profile manager, the local REST API, the MCP server and the sync server. The Wayfern Chromium engine it drives is proprietary, and this site says so wherever the claim is made. None of the four vendors compared across these pages names an open-source licence or a public source repository on the pages linked in the sources list.

Is there a free Multilogin alternative?

Yes, and it is not a trial. Donut Browser's free tier carries unlimited local profiles, per-profile proxy and WireGuard, the profile-management REST API and the MCP server, with no account and no card. Importing your existing profiles is free on every tier as well. The paid tiers add cloud backups, cross-OS fingerprints, seats and commercial use — never a higher profile count, because nothing counts them.

What Multilogin alternative do people recommend on Reddit?

No thread is quoted here, because none was read, and inventing one would undo the point of the rest of the page. What is offered instead of upvotes: the app's source is on GitHub under AGPL-3.0, the prices are published, and every claim about Multilogin above links to the page it came from with the date it was read. That is a slower answer than a recommendation, and it is one you can check yourself.

Can I import my Multilogin profiles into Donut Browser?

Not as Multilogin profiles — no antidetect vendor exports to another's format. What Donut reads is a Chromium profile directory, so point it at a folder, a browser user-data directory or a ZIP, whether it came out of Multilogin's own export or out of the Chrome, Brave, Edge, Opera, Vivaldi, Arc or Yandex profile underneath it. Renaming, grouping and proxy assignment happen in the same pass, and each imported profile gets a freshly generated fingerprint.

Do you need an account to replace Multilogin?

No. The free tier runs with no account, no card and no trial clock, because your profiles are directories on your own disk rather than rows in somebody else's database. An account appears only when you buy a paid tier or turn on cloud sync, and the sync server itself is open source and self-hostable.

Switching from Multilogin: what to do this week

A migration you cannot roll back is not a migration, so do it in the order below rather than all at once. None of the first two steps bills you or creates an account.

  1. Today

    Download Donut Browser and import one profile — the least important one you have. Check that it opens, that the proxy is bound and that the site still recognises the session.

  2. This week

    Run the real batch: point the importer at your browser's user-data directory or at an export from Multilogin, assign a group, and round-robin your stored proxies in the same pass.

  3. Before you cancel

    Keep Multilogin running until every imported profile has signed in and stayed signed in for a few days. Then cancel, and keep the export.
