InMerch gives merch and e-commerce teams one secure workspace to audit browser fingerprints, verify IP & WebRTC hygiene, generate realistic user agents, test addresses, birth dates and tax numbers, and bulk-check proxy lists — before accounts ever get linked.
The toolkit
Everything your team needs to keep every storefront isolated — available to approved members the moment access is granted.
Canvas, WebGL, fonts, screen, hardware, language and privacy signals are collected and hashed into a single SHA-256 identifier, so you can confirm each profile looks unique and coherent.
Look up your public IP, location and ISP across four providers, compare the IP timezone with the browser clock, and run a STUN-based WebRTC test that flags any address bypassing your proxy.
Generate up to 500 user-agent strings per batch for Chrome, Firefox, Safari and Edge across desktop and mobile. Version lines track today's release cadence automatically — no stale lists.
Bulk-check HTTP, HTTPS, SOCKS4 and SOCKS5 proxies with results streaming in live: exit IP, latency, location, ISP and Residential / Datacenter / Mobile type. Then convert the working ones to any format you need.
Generate up to 100 addresses per batch for 28 countries, from big cities to about 12,000 real villages. City, region and postal code always come from one real place, so they match; street, house number, name, phone and email are invented and follow each country's format.
Set a minimum and maximum age and get up to 1,000 random birth dates, each guaranteed to fall inside that age range today, leap-day birthdays included. Output them in 20 preset formats or your own pattern, with month names in 12 languages.
Generate test tax numbers for 165 tax number types across 124 countries, from VAT and company numbers to personal tax IDs. Each one follows the country's documented format, while the checksum is random, so the numbers are synthetic test data and never belong to a real person or company.
Platform
Every tool except the proxy checker runs locally in your browser. Proxy checks run on hardened InMerch servers and are never stored.
Every account is reviewed by an administrator before any tool code is delivered to the browser.
Access is re-verified on every request, so approvals and revocations take effect immediately.
Browser versions are derived from real release cadences, keeping generated profiles believable.
Timezone mismatches and WebRTC exposures are surfaced in plain language with clear verdicts.
No heavy frameworks. Each tool loads on demand, so the dashboard opens instantly on any device.
Security
InMerch is built on a minimal, auditable stack with security controls at every layer.
How access works
Register with your name, email and a strong password. It takes less than a minute.
An administrator verifies your request. You can check your status at any time.
Once approved, signing in takes you straight to your private toolkit.
FAQ
The toolkit is built for professional sellers and agencies. Reviewing every request keeps the community focused and the tools out of the wrong hands.
Most requests are reviewed quickly. Your status page updates automatically, and you'll be taken to the dashboard as soon as you're approved.
No. Fingerprint scans, user-agent, address, birthday and tax-number generation, and proxy formatting run entirely in your browser, and the IP check queries public geolocation services directly from your browser. Proxy checks run on InMerch servers only for the duration of the check; lists and results are not stored.
It's the combination of signals — screen, fonts, graphics hardware, timezone, language and more — that lets a site recognise a browser even without cookies.
HTTP, HTTPS, SOCKS4 and SOCKS5 in host:port, host:port:user:pass, user:pass@host:port and URL notation — for both live checking and conversion to JSON, CSV or custom templates.
Partly, by design. City, region and postal code are real, matching combinations taken from GeoNames (CC BY 4.0) and the U.S. Census ZCTA Gazetteer; street, house number, name, phone and email are randomly generated. They're meant for testing forms, checkouts and data pipelines, not for deliveries, payments or identity verification.
Age is counted in completed years on today's date in your browser, so every generated date belongs to someone who is between your minimum and maximum age right now. Someone born on 29 February turns a year older on 1 March in non-leap years.
No. They are synthetic test data. Each number follows the documented format of its country and type (length, letters, separators and fixed prefixes), but the check digits are random, so the numbers are valid in format only, not real or valid tax IDs. The built-in checker tests format only, and a random number can still match a real one by chance, so never use them in real forms, filings or payments.
