What MuLogin is
MuLogin is a Windows-centered profile system with main and sub-account administration, optional synchronized state, and a broad local REST surface for desktop, VM, or VPS workflows.
- Profile model: Profiles separate cookies, local storage, and cache and support per-profile proxies, groups, cloning, imports, exports, and optional synchronized state.
- Platforms: The client is documented for Windows and may run on a Windows VM or VPS; macOS, Linux, Android, and iOS labels describe represented environments.
- Team model: A main account can share or transfer profiles to sub-accounts and grant proxy-edit rights; cloud synchronization supports cross-computer state.
- Automation: REST resources cover profile lifecycle, groups, launch, stop, tabs, scripts, screenshots, cookies, and proxies, with Selenium and Puppeteer integrations.
Who MuLogin fits
A Windows-hosted isolated-profile browser with proxies, optional cloud synchronization, main and sub-account collaboration, profile transfer, and REST automation.
- Windows teams comfortable running browsers on local PCs, virtual machines, or VPSs.
- Operators using sub-accounts, bulk profile workflows, Selenium, or Puppeteer.
MuLogin and Isoline
MuLogin is current for Windows and established REST automation. Isoline is a planned macOS ARM64-first alternative centered on scoped automation, recovery, and secret redaction.
Isoline is in its foundation phase. Its local-first profile model, optional client-side-encrypted synchronization, recovery controls, and versioned automation interfaces are product direction until release evidence says otherwise. No public Isoline pricing or feature parity is implied.
- Compare documented current behavior, not feature-list promises.
- Validate migration, recovery, update freshness, permissions, and automation against the intended workflow.
What to verify before choosing MuLogin
Official documentation defines the factual starting point. A production decision still needs hands-on testing with authorized profiles, proxies, extensions, failure cases, and team permissions.
- Confirm API plan gates, authentication, and rate limits.
- Test sharing, transfer, same-profile locks, and synchronization recovery.
- Request encryption, signed-update, audit, backup, and reliability evidence.
