About EchoScan
EchoScan helps online services recognize returning devices across pre- and post-login journeys, retain device-to-account relationship context, and understand the overall state of each visit from current browser, operating-system, graphics, network, and automation signals. It gives developers, security teams, and risk teams this context inside their existing backend, where their own business rules determine the final action.
Built from long-term browser research
The project grew from sustained research into Chromium, anti-fingerprinting browsers, and differences among runtime environments. Small variations in browser versions, rendering paths, hardware capabilities, fonts, timezones, networks, and automation tools shape what a website can observe during a visit.
Those conditions keep changing, so the research continues. EchoScan follows the same discipline: verify environmental facts first, then expose stable results through a business-facing product contract.
From research tool to service
The public Scan lets any visitor inspect the current browser environment without an account. Browser Verifier serves developers inside customer sites and returns only a server-issued Imprint after a successful run.
The customer backend uses a Secret API Key to query Report API v1. Lite and Pro use the same base Report structure, providing device continuity, current-visit risk, and browser, operating-system, and network context. Lite and Pro both support History and optional Account Map, including new links and existing snapshot reads. Pro provides higher request allowances, rate limits, and Browser Environment capacity.
Device continuity, account relationships, and current-visit risk remain separate. Customers combine them with their own account, transaction, entitlement, and verification records to decide the final business action.
Who the service supports
EchoScan serves developers, security teams, and risk teams that need device continuity, account-relationship context, and a current-visit assessment. It is especially relevant to SaaS products, AI tools, API platforms, free trials, and other online services that grant costly resources.
The research also covers browser variation, anti-fingerprinting environments, automation, network risk, and privacy boundaries. The goal is clear technical evidence that customers can interpret inside their own business context.
Independent research background
EchoScan continues the working style of an independent creator engaged in long-term research and steady iteration. Product design, detection research, developer experience, and public documentation all emphasize verifiable facts and explicit boundaries.
The project evolves as browsers, operating systems, networks, and abuse techniques change. Public contracts stay stable while internal implementation continues to improve.
Privacy, Workspace, and decision boundaries
EchoScan does not identify a real person. Account Map uses a customer’s stable, non-sensitive internal reference, and its relationships are isolated by Workspace. Device history and account counts do not automatically change the current visit’s risk.status; the customer keeps the final business decision.
EchoScan publishes stable customer-facing contracts for Report, History, and supported integrations. Product implementation details unrelated to the public contract remain outside the public interface.
