Synchronizer — one action, many accounts at once

Open 5, 10 or 20 profiles in parallel windows, do something in one — Afina mirrors every click, keystroke and navigation across all of them. The fastest way to operate dozens of accounts simultaneously without scripting a thing.

Mirror • Batch • Manual

Manual multi-accounting at the speed of one tab

Some workflows aren't worth scripting — daily check-ins, quick UI tasks, on-the-fly tweaks. Synchronizer turns one human action into N parallel ones across selected multi-accounting profiles, with each profile still keeping its own session, fingerprint and proxy.

Mirror clicks, keys and navigation

Pick a master window, every other synced window replays the same DOM interactions in real time. Forms fill themselves across accounts; navigation cascades; uploads can target the same file or per-profile paths.

Parallel browser windows side-by-side

Open and tile multiple profile windows at once. Each is a real isolated Afina browser, not a copy — they keep their own cookies, fingerprint and proxy. The synchronizer is purely an input multiplexer on top.

One-click batch launch

Select profiles in the table, choose "Open synchronized" — Afina starts the browsers, waits for them to be ready, opens a synced session and tiles the windows. Pair with RPA for the parts that should run unattended.

Isolation is never broken

Mirror only inputs and navigation — never identity. Each account stays linked to its own fingerprint, proxy, cookies, storage. Synchronizer is the opposite of a "copy account" tool: it shares your actions, not your traces. Doubles as a fast sanity check that fingerprints stay isolated.

It turns one master browser window into N replicas. You click, type, scroll or navigate in the master, and Afina injects the same DOM events into every synced child window in real time. Each child stays a fully isolated browser — same input, different identity.

Practically as many as your machine can comfortably run in parallel. 5–10 is effortless on a typical M2 / 16GB; 15–20 starts to push memory; 30+ is fine on workstations. RAM is the bottleneck, not the synchronizer itself.

Synced: clicks, mouse moves, key presses, scrolls, navigation, form input. Not synced: cookies, sessions, fingerprints, local storage, IndexedDB, downloads, network responses. Every account remains its own entity — you're only sharing your inputs.

Yes — toggle sync on/off per window from the toolbar. Open a window unsynced, do something account-specific (different password, unique 2FA), then re-enable sync to continue the batch action.

Not directly — synchronizer is real-time, not record-and-replay. For repeatable workflows use the RPA canvas: build the flow once and run it on the same set of profiles via task groups. Synchronizer is the fast-and-manual sibling of RPA.

Synchronizer is a UI feature — it runs on top of the desktop windows you open from the table or via 'Open synchronized'. Profiles started via API remain available to Puppeteer/Playwright through the CDP endpoint, but they're not part of the synchronizer's tiled view unless you bring them in manually.

Operate 20 accounts as fast as one

Tile profile windows, sync them, run a manual workflow once — Afina mirrors it everywhere.

The Afina synchronizer mirrors mouse, keyboard and navigation actions from a master profile to N follower profiles in real time — control 20 browsers as if they were one. Each follower keeps its own fingerprint, cookies and proxy, so the actions are synchronised but the identities stay independent.

Some workflows are too dynamic for a pre-recorded script — captcha solving with rotating challenges, content moderation, manual quality checks across portfolios. The synchronizer lets one operator drive dozens of accounts manually, each on its own isolated profile, without losing the per-account state that multi-accounting depends on.

What's inside the synchronizer

1. Mirror clicks, types, scrolls and navigation

Action on the master profile replays on every follower with millisecond delay. Form fills, navigation, scroll position, copy-paste — all mirrored. Disable individual followers with one click if a flow goes wrong on a specific account.

2. Parallel windows on one screen

Tile follower windows on your monitor for visual oversight, or send them off-screen to save desktop real estate. Each window is a real browser — DevTools attachable, screenshotable, scriptable.

3. Batch launch

Open 50 profiles as one batch with one click. The synchronizer waits until every follower is ready before starting mirroring, so the first click doesn't reach a half-loaded browser.

4. Isolation preserved end-to-end

Mirroring is about actions — not about state. Each follower keeps its own cookies jar, IndexedDB, localStorage and fingerprint. Two followers on the same URL see different content (their personalised feed, their cart, their geo) — exactly what you want for real multi-accounting.

5. Combine with RPA and the API

Trigger a synchronized session from RPA when the manual step is needed; close it programmatically when done. The local API exposes start / stop hooks for orchestrators.

Where the synchronizer pays off

Captcha-heavy flows where an operator solves once and the answer applies across portfolios. Agency QA across client accounts. Content moderators reviewing the same submission from N reviewer accounts. Pen-testing and security research replaying the same probe under different fingerprint profiles. Manual airdrop claims where rotating wallets need eyes-on but identical actions. Anywhere a script can't capture the decision but the action itself is repetitive.
