An Anti-Detect Browser for Running Many Accounts.
Every profile gets its own device fingerprint and its own proxy, so platforms see separate visitors — not one machine with twenty logins. Profiles, cookies and history stay on your disk. Never on our servers.

How Anti4 Protects You
Encrypt Locally
AES-256 encryption happens on YOUR device. Keys never leave.
Store on Device
All data stays in your local encrypted vault. No upload. Ever.
Sync Your Way
Sync via YOUR cloud (AWS, R2, B2). Data encrypted before upload.
Automate with AI
CDP + MCP bridge. LLM runs locally or via API — data stays.
Only You Control
No master key. No backdoor. Even we can't recover your data.
Cloud Apps

Everything Encrypted. Nothing Uploaded.
Military-Grade Encryption

Sync Across Devices. Your Cloud. Your Rules.
Anti4 doesn't have a sync server. YOU choose where your encrypted data syncs. Connect your own storage — we never see your data, not even during sync.
- Data encrypted BEFORE upload — provider sees only ciphertext
- You own the storage account — revoke access anytime
- No vendor lock-in — switch providers in 1 click
- Sync profiles, settings, vault across all your devices
- Zero-knowledge sync — even if provider is compromised, data is unreadable
- Optional: run 100% offline with no sync at all

Simple. Honest. No Subscription Traps.
Try free. Pay once. Own forever.
flat price · no tiers · no subscription
- 1 key = 1 device
- Activates once — lifetime, no renewal
- Full features, every platform
Minimum order is 10 keys ($1.00).
No subscriptions. No auto-charges. Pay only for the keys you buy.
Need more devices later? Just buy more keys, anytime.
Forever. There's no expiry date, no subscription, and no renewal fee — you activate once and keep using Anti4 on that device for good.
Exactly one. Each key permanently binds to the first device that activates it — that's what keeps the price down at $0.10.
Buy a new key for it — at $0.10 each, adding a device costs less than a coffee. Keys are one-time-use by design and can't be moved between devices.
At $0.10/key, a single-key order barely covers payment processing. USDT orders start at 10 keys ($1.00).
USDT on either the TRC20 (Tron) or BEP20 (BNB Smart Chain) network. Send the exact amount shown at checkout and your keys are issued automatically once payment is detected. PayPal is temporarily unavailable while we finish maintenance — it is shown greyed out at checkout and will return.
