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 here was read from its own site on August 6, 2026. Moving across is not a profile conversion, because no antidetect browser exports a profile another one can open. It is a cookie export, 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.

Key Takeaways

  • Nothing converts a Multilogin profile into a Donut profile. What carries your accounts across is the cookie file: export it from Multilogin, import it here, and the sessions stay signed in. The fingerprint is always minted fresh, on any engine, by anyone.
  • 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.

What actually moves when you leave Multilogin?

Not the profile itself. No antidetect browser exports a profile in a form another one can open, so the honest question is which parts survive the move. Two of them do.

Nothing converts a Multilogin profile into a Donut profile, because Multilogin's export is an encrypted archive that only Multilogin can open. What moves is the session. Export your cookies from Multilogin, load them into a new Donut profile, and the accounts stay signed in. The fingerprint is not lost on the way across. It never was a file.

Multilogin's profile export is the most complete of any vendor here: it carries cookies, extensions, saved logins and fingerprint settings. It is also encrypted, and Multilogin states that exported files can only be imported back into Multilogin. The archive is a backup, not an exit. Export cookies separately instead. Donut reads JSON and Netscape cookie files through the app, the local REST API or MCP, and writes them in plaintext where the engine actually reads them. Creating the profiles is free on every tier.

Exact fingerprints will not be identical, because Multilogin uses its own fingerprint model.
Multilogin's own documentation, multilogin.com, read August 9, 2026

  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.

Which Chromium is Multilogin actually running?

Every anti-detect browser is a patched Chromium, and none of them is on the current one. The gap matters twice over: an engine that trails upstream trails it on web platform features and on security patches at the same time.

Chromium major version, read from each vendor's own release notes

Chrome stable was 151 on August 9, 2026. Where a vendor prints no version anywhere on its site, the row says so instead of showing a number you could not check.

Where do your Multilogin profiles actually live?

Not on your machine, in most of this market. Which matters on the ordinary day only a little, and on the day a subscription lapses quite a lot, because every vendor that holds your profiles also runs a clock on them.

Where the profile sleeps

Read from each vendor's own documentation on August 9, 2026. Where a vendor documents no deletion policy the row says so, because on this particular question silence is worth recording.

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 profiles. No antidetect vendor exports a profile in a format another vendor can read, and that includes Multilogin. What you move instead is the session: export your cookies from Multilogin, create the profiles in Donut, and import the cookie file through the app, the local REST API or MCP. Donut reads JSON and Netscape cookie files. Every new profile gets a freshly generated fingerprint, which is what Multilogin does with profiles imported into it as well.

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. Export cookies from Multilogin profile by profile, create the matching profiles in Donut, assign a group, and round-robin your stored proxies in the same pass.

  3. Before you cancel

    Keep Multilogin running until every rebuilt profile has signed in and stayed signed in for a few days. Sites re-check a device they have not seen before, so give them the chance. Then cancel.
