AdsPower, Multilogin, and Incogniton run on your machine. RelayKit's cloud antidetect browser runs in the cloud — no install, no local fingerprint, no device trace. The difference matters more than most people realize.
Desktop antidetect browsers like AdsPower, Multilogin, Incogniton, and GoLogin are applications you install on your computer. Each profile stores a spoofed browser fingerprint — a fake user agent, canvas hash, WebGL renderer, audio fingerprint, timezone, fonts, and screen resolution — so that each account you log into sees what appears to be a completely different device.
They work well for many use cases. The core limitation: the browser process runs locally. Your real hardware still exists underneath the spoof, and sophisticated fingerprinting scripts can sometimes detect the gap between the faked profile and the underlying machine. More practically, every profile consumes local CPU and RAM, and you need to keep the software updated, licensed, and running.
A cloud antidetect browser runs the entire browser process on a remote server — not your machine. The fingerprint presented to websites belongs to that remote session, not your hardware. You access the session via a live view in your own browser, or let an AI agent run tasks autonomously without any human in the loop.
Because nothing executes locally, there is no hardware fingerprint to leak. Even if a site runs aggressive fingerprinting, it only ever sees the cloud session profile. When the session ends, it's gone — no local state, no traces.
| Feature | Desktop (AdsPower / Multilogin) | Cloud (RelayKit) |
|---|---|---|
| Fingerprint source | Spoofed on top of your real hardware | Remote server — no local hardware exposed |
| Software install | Required — Windows/Mac app, updates needed | None — runs in your browser tab |
| Resource usage | Each profile uses local CPU/RAM | Zero local resources |
| Automation | API/Selenium integration possible | Built-in AI agent — no code needed |
| Proxy integration | Manual — configure per profile | Native — pairs with your RelayKit mobile proxy in one click |
| Pricing model | Monthly subscription ($50–$300+/mo) | Pay-per-session ($0.25–$0.50) |
| Concurrent sessions | Limited by your machine specs | Unlimited (each session on isolated cloud infra) |
| Profile persistence | Persistent — cookies, history saved | Ephemeral by default (stateless sessions) |
| Team sharing | Profile sharing via cloud sync (paid) | Sub-accounts and API access available |
Modern platform fraud systems don't just read your user agent. They run JavaScript fingerprinting scripts that probe your actual hardware: GPU model via WebGL, audio processing characteristics, CPU thread count, installed fonts, screen color depth, and more. A spoofed profile sitting on top of the same physical machine as 50 other profiles creates subtle correlations — same GPU, same CPU timing, same audio output — that link those accounts at the hardware level.
Cloud sessions sidestep this entirely. Each session runs on isolated infrastructure, so every fingerprint is genuinely separate hardware. There's no underlying machine to leak through.
Paired with a mobile proxy, the gap widens further. A cloud session using a RelayKit 4G/5G mobile proxy presents a mobile carrier IP from Verizon, AT&T, or T-Mobile — the same IP class real smartphone users generate. Combined with an isolated cloud fingerprint, there's no signal connecting your session to any other.
| Comparison | AdsPower / Multilogin | RelayKit Cloud Browser |
|---|---|---|
| Setup time | Download, install, configure, update | Create account → launch session in <60 seconds |
| Cost to start | $50–$150/month minimum | $0.25 per session — no subscription |
| Proxy setup | Enter proxy details manually per profile | Select your active RelayKit proxy from a dropdown |
| AI automation | Not built in — requires Selenium/RPA | Native AI agent handles tasks end-to-end |
| CAPTCHA solving | Third-party service required | Included in AI Agent sessions |
If you need persistent, long-lived account profiles with full cookie history, desktop antidetect is still the right tool. If you need clean sessions, automation, and per-task billing without a subscription or local software overhead — cloud wins by a significant margin. For most scraping, verification, and AI agent use cases, there's no reason to pay $150/month for a desktop tool when $0.25/session covers the same ground with stronger fingerprint isolation.
No subscription. No install. Launch your first session in under a minute.
