Merca

Multi-store fingerprint browser for cross-border sellers

Merca is a multi-store fingerprint browser for cross-border e-commerce sellers in mainland China. Manage Amazon, TikTok Shop, Shopee, and other marketplace stores on one computer. Keep browser environments, sign-ins, and local data separate for each store. Manage passwords, TOTP, and passkeys in one place, and give teammates access to the stores they need.

Why sellers use Merca

Built for cross-border teams managing stores across marketplaces: separate store environments, centralized credentials, and access assigned by store.

A separate environment for each store

Each store has its own browser data directory for sign-ins, history, and local data.

Choose your network provider

Bring your own proxies without being tied to a specific network provider. Use a proxy chain to connect through a local proxy before reaching the store's proxy.

Work as a team

Create accounts for operations and support staff, then assign store access without sharing the Merca owner account.

Reduce sign-in mistakes

Login checks, IP usage history, and a blocklist help identify node and account conflicts before a store opens.

Logins in one place

Manage passwords, TOTP, and passkeys by store, with less time spent finding credentials or copying and pasting.

Automation

Manage and launch stores through the local API or MCP, then use your own browser automation tools for repetitive tasks.

Tools for cross-border store management

Manage store environments, sign-ins, and team access for everyday cross-border e-commerce operations.

Per-store fingerprint settings

Save device fingerprint settings for each store and configure separate browser environments on the same computer.
How store fingerprints work in Merca

Separate store data

Cookies, cache, and local data are stored separately for each store to reduce sign-in mix-ups between accounts.

Choose your network provider

Bring your own proxies and add them as nodes in Merca. Buy and manage proxy services directly with your provider; Merca doesn't sell them.
Add a node

Proxy chain

Connect through a local system proxy or custom proxy before reaching the store's exit proxy.
How the proxy chain works

Taskbar and window labels

Give each store a name and color to tell windows apart in the taskbar and reduce mix-ups.

60+ e-commerce platforms

Open seller dashboards for Amazon, Shopee, TikTok Shop, and other major marketplaces.

IP blocklist

Track node IP usage and use a blocklist to restrict those IPs from being used for store sign-ins.

Login checks

Check for conflicts in node usage records and accounts before launch, with warnings or blocks when issues are found.
How login protection works

Password autofill

Save credentials by store and autofill them on supported sign-in pages to reduce manual entry.

TOTP two-step verification

Save TOTP settings by store and generate time-based codes without switching between your phone and computer.
