Short answer — here are commonly used, reasonably priced antidetect / multi‑account browser solutions and what to look for when choosing one. Note: use these only for legitimate, policy‑compliant tasks (marketing, QA, customer-support, research). Evading platform rules or committing fraud can get accounts banned or cause legal exposure.

Recommended options (well‑known, broadly used)

• Multilogin — enterprise‑grade, strong fingerprint isolation, team features and API. Widely used by digital agencies.
• AdsPower — focused on ad/marketing use cases; competitive pricing and team management features.
• GoLogin — solid balance of price and features, easy profile/proxy management, has an API.
• Incogniton — good for bulk profile creation and management, with proxy support.
• Kameleo — desktop and cloud options, supports many fingerprint settings and proxy integration.
• Ghost Browser — browser built for tab/workspace isolation and multi‑account workflows (less about deep fingerprint spoofing, more about convenience).
• SessionBox (extension) — inexpensive/free option for lightweight profile separation in a single browser.

What to compare when choosing

• Profile isolation level (cookie/storage/CH/UA vs. full fingerprint simulation)
• Supported browser engines (Chromium, real Chrome, Gecko) and OS emulation
• Proxy support (per‑profile proxies, proxy pools, SOCKS/HTTP/rotation)
• Team / user management, shared workspaces, and API availability
• Number of concurrent profiles per subscription and pricing model (per profile vs. seats)
• Security & logging (who can access profiles, audit logs)
• Customer support, updates, and reputation

Legality, terms of service, and ethics

• Many platforms forbid automated or deceptive multi‑accounting. Using antidetect tools to evade those rules is risky.
• Even for legitimate uses, follow applicable laws, platform TOS, and company policy.
• Prefer vendors that emphasize compliance and enterprise features (role controls, audit trails).

If you want, I can:

• fetch and compare current prices and feature tables for 3–4 of these tools, or
• recommend the cheapest option for a specific use (e.g., managing 10 social media accounts vs. QA/testing).
