Many browsers. One calm place to run them.
Blend keeps each of your browser profiles separate, with its own fingerprint, proxy and cookies. It runs on your computer and works without an account.
Unsigned beta: Windows SmartScreen will warn you on first launch. How to install.
Everything you need to keep profiles apart
It's built for people who manage several accounts legitimately: agencies, marketplace sellers, QA testers and privacy-minded users.
Isolated profiles
Each profile has its own cookies, storage, cache and extensions. Nothing leaks between them.
Consistent fingerprints
Device presets keep user agent, screen, GPU, timezone and language in sync, and a health score warns you about mismatches.
Bring your own proxies
HTTP and SOCKS5 with authentication, bulk import and checks. DNS goes through the proxy. Blend never sells proxies.
Automation built in
A no-code flow builder, Cookie Robot, Synchronizer, and a local REST API for Puppeteer, Playwright and Selenium.
End-to-end encrypted sync
Optional cloud sync. Profiles, proxy passwords and cookies are encrypted on your PC before upload.
Teams
Roles, granular permissions and profile sharing with view, launch, edit or full access.
Honest by default
- Local-first: the free plan never needs an account or a server.
- Zero-knowledge sync: we can't read your profiles, passwords or cookies.
- No proxy reselling and no selling of data. Ever.
- Fraud and abuse are banned by our Acceptable Use Policy.
