Looking for Octo Browser alternatives?

A local Octo Browser alternative: profiles are folders on your own machine, so nothing meters them, nothing bills you to take one out, and nothing deletes them when you stop paying. Every claim about Octo Browser here was read from its own site on August 9, 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.

The question behind "Octo Browser 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 Octo Browser profile into a Donut profile. What carries your accounts across is the cookie file: export it from Octo Browser, 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 6 axes, and every Octo Browser cell carries the URL it was read from and the date it was read — August 9, 2026. Nothing about Octo Browser is quoted from memory.
  • You need the newest Chromium major as soon as it lands. Octium tracked Chromium 151 on 30 July 2026; the shipping Wayfern build is on 150.

What actually moves when you leave Octo Browser?

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 Octo Browser profile into a Donut profile, because Octo Browser's export is a .octo file another Octo account can import exactly once, billed at 0.5 tokens per profile. What moves is the session. Export your cookies from Octo Browser, 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.

Octo's export is the most complete in this market and the most locked: the file carries the fingerprint and the cookies, it costs 0.5 tokens per profile, and it can be imported once, into Octo. Octo itself says automatic transfer from another anti-detect browser is not available and that profile settings have to be recreated, which is the same wall from the other side. So export the cookies by hand, rebuild the profiles here, and load the file. 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.

When generating a fingerprint, make sure to use the same OS as the one you are transferring the account from. Set Hardware Settings as close as possible to the system you are transferring from (CPU/RAM/GPU).
Octo Browser's own documentation, docs.octobrowser.net, 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 Octo Browser 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 Octo Browser 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 Octo Browser 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 Octo Browser cell restates something published on its own site, read on August 9, 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.

    Octo Browser

    Proprietary, and the licence says so in detail: you get a personal, non-transferable licence to use the software, source code excluded, with reverse engineering forbidden. [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.

    Octo Browser

    There is no free plan. The cheapest published tier is Lite at €10 a month for 3 profiles, before VAT. [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.

    Octo Browser

    The subscription, and then the exit: taking a profile out costs 0.5 tokens, and the file it produces can be imported once. [3]

  • 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.

    Octo Browser

    In the Octo account, on a clock: 6 months without a subscription and every profile in the account is deleted. [4]

  • Browser engine

    Donut Browser

    One engine, Wayfern: an anti-detect Chromium whose fingerprint spoofing is enforced in C++, currently on the Chromium 150 major.

    Octo Browser

    Octium, a Chromium build the vendor moves to each new major about monthly. It was on Chromium 151 on 30 July 2026, level with Chrome stable. [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.

    Octo Browser

    The API starts at the €79 tier and its throughput is part of what you buy: 50 requests a minute at Base, 100 at Team, 200 at Advanced, and none below. [6]

How much does this Octo Browser 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 Octo Browser 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 Octo Browser side of it needed a source, it has one.

  • You need the newest Chromium major as soon as it lands. Octium tracked Chromium 151 on 30 July 2026; the shipping Wayfern build is on 150. [5]

  • You hand whole profiles to other people. An Octo export carries the fingerprint and the cookies into another Octo account in one file; Donut Browser moves cookies, and the profile is rebuilt at the far end. [7]

  • 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 run accounts from an iPhone or iPad. Octo publishes an iOS app; Donut Browser is desktop only. [8]

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.

Octo Browser alternative: common questions

Is there a free Octo Browser 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.

Is there an open source Octo Browser 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.

What Octo Browser 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 Octo Browser 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 Octo Browser profiles into Donut Browser?

Not as profiles. No antidetect vendor exports a profile in a format another vendor can read, and that includes Octo Browser. What you move instead is the session: export your cookies from Octo Browser, 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 Octo Browser does with profiles imported into it as well.

Do you need an account to replace Octo Browser?

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 Octo Browser: 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 Octo Browser 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 Octo Browser 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.
