Frequently asked questions
What is Blend Browser?
A Windows desktop app that runs many separate browser profiles. Each profile has its own cookies, storage, proxy and consistent fingerprint, so accounts stay isolated.
Is it really free?
Yes. The Free plan includes 10 profiles, proxies, the fingerprint editor, local automation API and encrypted sync. Paid plans add more profiles and team features.
Does Blend sell proxies?
No. Blend never sells proxies. You can add your own HTTP, HTTPS or SOCKS5 proxies and test them in the app.
Can you see my profiles or passwords?
No. Cloud sync is end-to-end encrypted with a key derived from your password on your device. Our server only stores ciphertext.
Which systems are supported?
Windows 10 and 11 (64-bit) for now. macOS and Linux are planned.
Why does Windows show a SmartScreen warning?
The beta installer is not code-signed yet. Click "More info" then "Run anyway". Signing will be added before the stable release.
Can I automate profiles?
Yes. Every profile exposes a Chrome DevTools endpoint, so Puppeteer, Playwright and Selenium work. There is also a no-code flow builder and a REST API.
Is it allowed to use Blend for anything?
No. Fraud, account takeover, spam, evading bans for abuse and other illegal use are forbidden by the Acceptable Use Policy, and we close accounts that break it.
Can I get a refund?
Paid plans can be refunded within 14 days of the first payment. See the refund policy.
