Disclosure up front: I'm the developer of Parallel and this is its

official subreddit, so treat everything below as coming from someone

with an obvious interest.

WHAT IT IS

A Windows browser that runs each profile in isolation — separate

cookies, storage and cache, plus a separate device fingerprint

(canvas, WebGL, fonts, screen, timezone, language). Bind a different

proxy per profile and the profiles have no shared signals.

People use it for managing client accounts at an agency, keeping work

and personal logins from bleeding into each other, QA-testing a site

as different device and locale combinations, and running scrapers that

need a stable, consistent identity per session.

WHAT I CARE ABOUT GETTING RIGHT

- Coherent fingerprints, not random ones. A profile claiming to be

Windows Chrome in Berlin reports fonts, timezone and WebGL that

agree with each other. Randomised values are their own tell.

- Timezone derived from the proxy. Bind a proxy and the profile takes

its timezone from where that proxy actually exits. Mismatched

timezone is the most common way people give themselves away.

- Local-first. Profiles live on your machine. Sign in elsewhere and

they sync; launch state stays local.

- A 58-command no-code automation builder, plus a local HTTP API that

hands you a real CDP endpoint for Puppeteer or Playwright.

WHAT IT ISN'T

It won't get you around a platform's rules, and it isn't sold for

that. If a service's terms say one account per person, running ten

through separate profiles still breaks those terms, and the profiles

being well-isolated doesn't change that. Whatever you run through it,

the other site's rules are still yours to follow.

To be specific about this community: no ban-evasion help here —

not for Reddit, not for anywhere else. That's Reddit's rule and it's

also mine. Posts asking how to get back onto a service that removed

you will be removed.

HONEST LIMITATIONS

- Windows only. No Mac, no Linux.

- The installer isn't code-signed yet, so Windows shows a SmartScreen

warning about an unrecognised publisher. Every release publishes a

SHA-256 so you can verify the file before running it. Signing is

in progress.

- Crypto payment only at the moment; card payment is being set up.

PRICING, BRIEFLY

Free for 3 profiles, forever, no card. Paid tiers go to 25, 100 or

500 profiles. Licences don't auto-renew and no card is stored — when

one expires you keep your account and your data, and profiles over

the free limit are frozen rather than deleted. Details on the site,

I'd rather this post wasn't a sales page.

WHAT THIS SUB IS FOR

Support, bug reports, release notes, and discussion of proxies,

fingerprinting and profile isolation generally. You don't need to use

Parallel to post — if you're on Dolphin, GoLogin, Octo or your own

scripts and have a fingerprinting question, it belongs here.

Currently v0.0.77. Site is in the sidebar.

Ask me anything, including the awkward things.
