Undetectable Review 2026

What is Undetectable?

Undetectable (undetectable.io) is a Chromium-based antidetect browser for Windows and macOS built around one core promise: managing an effectively unlimited number of accounts without risking access loss. It positions itself as a tool for multi-accounting teams — affiliate marketers, e-commerce sellers, ad buyers, and agencies — who need many isolated browser identities that look like distinct real devices. The product splits profiles into two buckets: cloud profiles that sync across machines and team members, and local profiles stored on your own disk, where the count is unlimited even on lower tiers. By the company's own figures it serves a sizeable user base, citing 120,000+ users on its homepage.

Key features

The fingerprinting engine replaces a broad set of device parameters: UserAgent, OS, screen, CPU cores, memory, browser, languages, WebGPU, WebGL, WebRTC, and geolocation. That WebGPU coverage is worth flagging — many competitors are slower to spoof newer surfaces, so its inclusion here is a genuine point in Undetectable's favor. The browser engine tracks recent Chromium releases (version 149 was referenced at the time of review), which matters because a stale Chromium version is itself a detectable signal.

• Mass creation: generate hundreds of unique profiles in a few clicks, useful for bulk account setup.
• Synchronizer: perform the same actions simultaneously across multiple profiles — a practical time-saver for repetitive multi-account workflows.
• Cookies Robot: automatically and randomly visits popular sites to build up cookie history, helping profiles look aged rather than freshly minted.
• Configuration store: ready-made browser fingerprint configurations sold from $1 each, so you can buy additional real-device fingerprints rather than relying on synthetic generation.
• Team roles: custom roles with 33+ settings, profile grouping, and activity logs for account management at agency scale.

For automation, Undetectable exposes a local API and supports Puppeteer, Playwright, and Selenium via the Chrome DevTools Protocol, so engineering teams can drive profiles programmatically without leaving their existing stack.

Pricing (verified)

Undetectable runs a genuinely usable Free plan at $0: 5 cloud profiles, 1 user session, 10 browser configurations, and a 50-profile monthly creation limit, with local profiles, proxy import, cookie export, the cookies bot, and Chrome extension support included. That is enough to evaluate the product properly before paying.

• Base — $49/month: 50 cloud profiles, 1 user, 25 configurations (extra configs at $1 each), plus proxy export, local API, profile import/export, and mass creation.
• Professional — $99/month: 100 cloud profiles, 2 users (additional users $20/month each), 50 configurations.
• Custom — $199/month: 200+ cloud profiles (an extra 1,000 profiles for $100), 5+ users (additional users $15/month each), 100 configurations, with optional private cloud storage at $500/month.

Payment is accepted via cards from any region plus a wide range of cryptocurrencies (Bitcoin, Ethereum, USDT, USDC, BNB and others). The pricing logic is clean: you pay primarily for cloud-synced profiles and seats, while local profiles stay unlimited — a structure that rewards solo operators who don't need cloud sync.

Proxy integration

Undetectable ships a built-in Proxy Manager that supports SOCKS5 and HTTP/HTTPS proxies. You bring your own proxies (proxy import is available even on the Free plan, with export unlocked on paid tiers), assigning a distinct proxy per profile so that IP, geolocation, and the spoofed fingerprint stay consistent. There is no first-party proxy marketplace baked in, which is fine if you already have a trusted residential or mobile proxy provider, but means there's no one-click proxy purchase path for newcomers. In practice the per-profile assignment model is standard and works smoothly with any mainstream proxy vendor. Because proxy import is available even on the Free plan, you can validate that your proxies behave correctly against the spoofed fingerprint before committing to a paid tier — a sensible workflow that avoids paying first and discovering proxy-leak problems later. WebRTC handling in particular is worth testing here, since a leaking real IP is one of the most common ways a carefully built profile gets unmasked, and Undetectable's inclusion of WebRTC among its spoofed parameters means the per-profile proxy and fingerprint can be kept fully aligned.

Strengths and weaknesses

• + Unlimited local profiles even on entry tiers, so cost scales with cloud/team needs rather than raw profile count.
• + Broad fingerprint coverage including WebGPU, WebGL, WebRTC and geolocation — ahead of some rivals on newer surfaces.
• + Real free plan (5 cloud profiles, 10 configurations) that lets you validate the tool before spending anything.
• + Strong automation support with a local API plus Puppeteer, Playwright and Selenium over CDP.
• − Cloud profile caps are modest per tier (50/100/200), so cloud-heavy operations escalate to the Custom plan quickly.
• − No built-in proxy marketplace, so you must source proxies separately.
• − Configurations are metered and capped per plan, with extras billed at $1 each — a small but real recurring cost at scale.
• − Windows and macOS only; there is no native Linux client for server-side deployments.

Verdict

Undetectable is a solid, fairly priced workhorse for multi-accounting teams who value unlimited local profiles and want a credible free tier to test against. Its fingerprint engine is modern and its automation hooks are exactly what scripting teams expect. The main constraints are the metered cloud profiles and configurations, and the lack of Linux. If you need Linux support, headless server deployment, or a developer-first SDK with Docker, Kameleo is the more natural fit; teams that want an integrated proxy shop and polished team controls should also weigh Octo Browser. But for a straightforward Windows/macOS multi-accounting setup with generous local capacity, Undetectable earns its place on the shortlist.
