Anti-detect browser
Many accounts, one browser.
Quark is an anti-detect browser for teams that run many accounts, built on Chromium, with Snaga agents inside. Every account lives in its own profile, and you can hand Quark a task in a chat.

A reminder that you set the boundaries.
A profile per account
Every profile is its own window with its own cookies, country, language, time zone and device. Profiles are shared with your team and stay in sync between your Macs.
A fingerprint that holds together
Each profile carries a persona you choose: browser and client hints, screen and window size, WebGL, canvas, audio, fonts, media devices, WebRTC mode, time zone and locale, consistent with one another. Quark never picks a persona for you.
A proxy per profile, checked
Each profile has its own proxy chain, and the checker shows its exit address, country, time zone, city and provider before you start. A profile without a proxy is flagged.
It starts with a chat
Quark's home page is a chat. Describe the task in plain words; Quark answers itself or hands it to a profile, to Snaga Code or to Svitlo, and calls you only when your word is needed. What waits for you is under Tasks.
Your confirmation where it matters
Passwords, mail, payments and account deletion always wait for your confirmation, whatever level of autonomy you set.
Agents inside
Snaga Code writes code in your projects, and Svitlo investigates public Telegram channels — both are pages of the same browser, on the same account.
Before you install
This is a test build for Mac with Apple silicon; Windows and Intel Macs are in internal testing. Quark needs a Snaga account to work at all: nothing in it runs before you sign in.
