Profiles
A profile is one isolated identity — its own browser data directory, cookies, and a coherent fingerprint. Every field below is optional except the name; everything else defaults to "derive it from the seed."
Basics
| Field | What it does |
|---|---|
| Name | Required. Shown everywhere in the profile grid and pickers. |
| Group | Optional. Organizes the grid and drives the group filter chips — pick an existing group or create one inline. |
| Notes | Free text, for your own reference only — never sent anywhere. |
| Start URLs | One or more URLs, opened as tabs the moment the profile launches. |
Fingerprint & engine
Every profile has a fingerprint seed that deterministically derives its entire identity — user agent, screen, hardware, canvas/WebGL/audio noise, fonts, timezone, and locale all stay internally consistent instead of being randomized independently (the thing most fingerprint spoofing gets wrong). The same seed always produces the same fingerprint, so a profile's identity is stable across relaunches.
| Field | What it does |
|---|---|
| OS | Windows, macOS, or Auto — Auto derives it from the seed for a natural distribution across profiles you create. |
| Chrome version | Pin a specific real build (e.g. 150.0.7871.124) or leave on Auto for the current default engine. The faked user agent and client hints always match whichever engine actually launches. |
Proxy
Bind a proxy from the Proxies page (HTTP, HTTPS, or SOCKS5, with optional auth) or leave it unset for a direct connection. Use the proxy list's Test button before relying on one — it reports exit IP, geo, and latency through the actual proxy. The profile's timezone is derived from the proxy's geo when one is bound, and WebRTC is leak-prevented so the browser's real IP can't leak around the proxy.
Platform quick-login
Pick a platform from the preset list (Facebook, Google, Amazon, Instagram, TikTok, X/Twitter, LinkedIn, Reddit, Pinterest, eBay, Discord, Shopify) or choose Custom and supply your own login URL. When set, that login page opens as the first tab on launch, ahead of any Start URLs.
You can also save a username/password for the platform right in the profile editor.
Manual fingerprint overrides
Collapsed under "Advanced" in the profile editor. Every field defaults to Auto (derive from the
seed, the same as before this existed) — set only the ones you need a specific value for.
| Field | What it does |
|---|---|
| Timezone | An IANA zone, e.g. America/New_York. |
| Language | A BCP-47 tag, e.g. en-US — also drives navigator.languages and Accept-Language. |
| Screen width / height | Both must be set together — a lone width or height is ignored. |
| WebRTC mode | Auto (leak-controlled, the default), Disabled (removes RTCPeerConnection entirely), or Real (no patching at all). |
| Hardware concurrency | Overrides navigator.hardwareConcurrency (CPU core count). |
| Device memory | Overrides navigator.deviceMemory, in GB. |
Groups & bulk actions
Create, rename, and delete groups from the Profiles page — an empty group persists even with nothing in it yet. Filter chips let you narrow the grid to one group at a time. Multi-select a set of profiles to launch, stop, delete, move to a group, or assign a proxy to all of them at once instead of one at a time.
Session import/export
Import or export a profile's cookies in the common Cookie-Editor / EditThisCookie JSON format — a fast way to move an already-logged-in session into or out of Parallel.
Cloud sync
Signed in, your profiles, proxies, groups, and RPA processes all sync to your account — sign in on another machine and they're already there. Two things are deliberately not synced and stay local to each machine:
- Run status — whether a profile is currently launched only makes sense on the machine actually running it.
- Saved platform login credentials and RPA run logs — local-only by design, covered above and in the RPA guide.
