Manage every client account without bans.
The antidetect browser for social media teams. Unlimited isolated profiles for Instagram, TikTok, X, and Facebook: no per-profile fees, free and open source.
Why agencies and freelancers use an antidetect browser for social media
Instagram, TikTok, X, and Facebook link accounts through the browser, not just the login. Shared cookies, one device fingerprint, one IP address: that is all it takes for a platform to connect your client accounts and suspend them together.
Donut Browser gives every client account its own browser identity. Each profile carries a unique fingerprint, isolated cookies and storage, and its own proxy, so Instagram sees ten unrelated users instead of one agency juggling ten logins. Whether you manage 3 accounts or 50+, there is no per-profile fee and no seat limit: the browser is free and open source.
Team handoff is built in too. Donut Sync shares profiles between teammates with end-to-end encryption, so an account manager can pick up a client session with the same device identity: no passwords in a spreadsheet, no fingerprint mismatch that triggers a security review.
Stop paying per profile. Stop losing accounts.
Unlimited isolated profiles for every client, free and open source. Add per-profile proxies and encrypted team sync when you need them.
Key Features
Unlimited profiles, zero per-profile fees
Run 3 client accounts or 300. Donut Browser never charges per profile or per seat, so growing your agency does not grow your tooling bill.
One isolated fingerprint per account
Every profile spoofs canvas, WebGL, audio, fonts, and more into a stable, unique device identity. Instagram and TikTok never see two clients on the same hardware.
Per-profile proxies that stick
Assign each client account its own HTTP, HTTPS, or SOCKS proxy once and it persists across sessions. Geo-consistent IPs keep logins from tripping security checks.
End-to-end encrypted team sync
Share client profiles with teammates through Donut Sync. Cookies and sessions transfer encrypted, so handoffs need no shared passwords or 2FA codes.
No cross-account contamination
Cookies, localStorage, IndexedDB, and extensions are fully separated per profile. A restriction on one client account cannot cascade to the rest.
Free and open source
AGPL-3.0 licensed with zero telemetry. Audit the code, self-host the sync server, and keep client data on your own machines.
How It Works
Create a profile per client account
Spin up one isolated profile for each Instagram, TikTok, X, or Facebook account. Each gets a unique fingerprint automatically.
Attach a dedicated proxy
Give each profile its own residential or mobile IP so the location matches the account. Set it once and it sticks.
Log in and warm up
Sign in to the client account inside its profile. Cookies and sessions persist, so daily logins look like the same trusted device.
Share with your team
Sync profiles to teammates with end-to-end encryption. Handoffs keep the same device identity, without password spreadsheets.

Built for the platforms you manage
One isolated browser identity per account, on every network your clients live on.
Instagram
Manage multiple Instagram accounts without bans. Each profile presents a unique device fingerprint, keeps its session between logins, and routes through its own proxy so every client location stays consistent.
TikTok
Run client TikTok accounts side by side. Isolated storage stops cross-account linking, and stable fingerprints keep accounts out of review queues.
X (Twitter)
Operate brand and client X accounts in parallel without triggering ban waves. Each profile looks like a separate device with its own cookies and IP.
Facebook
Keep Pages, ad accounts, and community profiles separated. Isolated profiles protect Business Manager access when one account catches a restriction.
Everything runs on your machine, no account required
