LocalFingerprint – Local-first fingerprint browser

A fingerprint browser where profiles and cookies never leave your machine

Problem

Commercial fingerprint browsers are fine for throwaway accounts, but many people refuse to put high-value main accounts, wallet credentials or core service cookies into closed-source clients that sync profiles and cookies to the cloud by default. Users are explicitly asking for alternatives with pure local storage, no cloud sync and better transparency.

Solution

An open-source local-first fingerprint browser where every profile, cookie and setting lives only in an encrypted local database, with cloud sync and telemetry off by default and the sync logic publicly documented. Users can physically isolate their main account while keeping basic multi-account management.

Users

E-commerce operators, cross-border sellers and privacy-conscious developers who manage high-value accounts or assets and need multi-environment isolation

MVP

Create and manage multiple local browser profiles with independent cookies and storage; store everything in encrypted local files only; disable any cloud sync by default and clearly show network requests; import common fingerprint browser profiles; publish an open-source audit guide

Revenue

Core open source for free; one-time Pro license for encrypted backups, team profile import/export and priority support

Why now

The cloud-sync controversy around closed-source fingerprint browsers is long-standing, yet there is no truly local-first auditable alternative; a solo dev can build on existing open browser cores at low cost
