What’s actually slowing this PC down?

Choose a local browser profile when keeping profile data on a device you control matters most. Choose cloud profile sync when you need cross-device access or team handoffs and are comfortable with profile data being held by a provider. Consider remote browser execution separately: in that model, the browser itself runs on the provider’s infrastructure. Because vendors use “cloud” for both syncing and hosted execution, establish exactly what leaves your device before comparing products.
What “cloud” means in an antidetect browser
The label does not tell you where the browser runs or where its data lives. These are three distinct arrangements:

- Local profiles and local execution: The profile data and browser process stay on your device. You control the device, but you also need to manage its security, backups, portability, and any product licensing requirements.
- Cloud profile storage or sync: The browser can still run on your computer while profile data is stored or synchronized through the vendor. Undetectable, for example, documents both local profiles and cloud profiles, with cloud profiles available across internet-connected devices. Its documentation also describes groups, activity logs, and an optional self-hosted storage path. These are vendor-described features, not an independent security audit. Undetectable’s documentation
- Remote or hosted browser execution: The browser process runs on provider infrastructure, and you access it remotely. Sendwin describes a streamed cloud browser running on a server in Helsinki, Finland, alongside a desktop app that runs locally. The provider’s infrastructure, session handling, network egress, and server location therefore enter the trust decision. Sendwin’s product information
A hybrid product may support more than one arrangement, such as syncing a profile and launching it locally or remotely. Sendwin documents that pattern, while Undetectable documents profile-type conversion. Neither fact establishes how a particular product handles sync conflicts, data copies, concurrent use, or plan restrictions; check those details for the product you are considering.
Which model fits your work?
Choose local storage for device control
Local storage is a sensible starting point if one person or a small operation works mainly from a fixed, managed workstation, wants logged-in profile data under direct device control, and would rather avoid dependence on vendor storage or a continuous internet connection. It shifts responsibility to you: protect the workstation, manage who can access it, and maintain a backup and recovery path.

Do not assume that “local” means the product will work without its vendor. Check whether local profiles launch under the product’s licensing rules, and test how to export and restore a profile before relying on it.
Choose cloud profile sync for mobility or collaboration
Cloud sync can help when you need to move between devices, share profiles with teammates, or coordinate work across locations. Before adopting it, establish which profile fields are copied, how access is assigned and revoked, whether simultaneous use is restricted or logged, and whether self-hosting is available. Confirm that the plan covers the number of profiles and seats you need.

Consider remote execution when the browser must run elsewhere
Hosted execution may suit work that needs to continue away from your device, a remote workstation without a local installation, or centrally managed execution. Check latency and streaming quality, where the server is located, which network connects to the target site, and whether the target service permits the remote environment. This is not simply cloud backup: the browser process and active session move to provider infrastructure.

- Compatible Models: Width: 13 9/16" (13.5 inch/344 mm), Height: 7 5/8" (7.6 inch/194 mm), Diagonal: 15.6" (396.24 mm) widescreen laptops which have a 16:9 aspect ratio. Not touchscreen compatible !!! Not fit for 16:10.Do NOT rely solely on your laptop’s diagonal size when ordering. Use a ruler to measure your screen’s visible area (excluding the black bezels). If the width reads 344mm and height reads 194mm, this filter is a perfect match for your device.
- Keep Information Privacy: Effective "black out" privacy from side views outside the 60-degree viewing angle.

Use a hybrid model only after checking its boundaries
A product that can sync profiles and launch them locally or remotely offers flexibility, but also makes it important to understand where copies exist and how they behave. Verify sync conflicts, concurrency rules, profile conversion behavior, and which plan enables the required launch mode.
Compare vendors by the boundaries that matter
| What to check | Question to ask | Why it matters |
|---|---|---|
| Runtime location | Does the browser run on your device, a vendor server, or both? | Separates local execution from remote hosting. |
| Profile data boundary | Where are cookies, storage, passwords, history, passkeys, and fingerprint settings kept? | Shows what the local device or provider may hold; implementations differ. |
| Network path | Which machine and network connect to the target site, and which proxy is used? | Hosted execution may put the connection on provider infrastructure. Profile sync alone does not establish the network path. |
| Portability and recovery | Can profiles be exported, restored, or opened on another device? | Determines how you recover from a lost device or leave the service. |
| Team access | Are roles, sharing controls, and usage logs documented? | Important when more than one person can use a profile. |
| Service dependence | What happens if the vendor service, license check, or internet connection is unavailable? | Continuity depends on the product and execution model; a local install alone does not answer this. |
| Hosting geography | Where are profile data or hosted browser sessions stored or run? | Relevant to operational and data-governance requirements. Sendwin identifies Helsinki for its cloud browser; that location should not be assumed for other providers. |
| Plan limits and cost | What are the limits on profiles, seats, concurrent sessions, storage, automation, and billing period? | A headline monthly price may not cover the team size or concurrency you need. AntiBrow says its concurrency and cloud-sync features depend on the plan. AntiBrow’s product information |
| Detection claims | What is backed by documentation or reproducible testing? | Architecture alone does not establish detection outcomes; no guarantee is supported by these sources. |
Questions to ask before moving a profile
Ask the vendor—or verify in its documentation—where the browser runs, which session data leaves your device, where that data is stored, who can access it, and whether it is encrypted in transit and at rest. Ask what remains after deletion, whether activity logs are kept, and how to export and restore profiles. For hosted execution, also ask where sessions run and where their network traffic exits. Finally, find out what happens if the service, license check, or internet connection becomes unavailable.

These questions matter because the implementations documented by vendors differ. The cited product pages do not independently audit each vendor’s security controls, so a feature description should not be treated as a security certification.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Clear out junk files and repair common Windows errors3Fix the driver behind crashes, sound loss and screen glitchesKeep architecture separate from detection claims
Local storage, cloud sync, and remote execution describe where data or software runs; none establishes that a browser will avoid detection. Browser fingerprinting is one identification surface, but Nasser Mohammed Al-Fannah and Wanpeng Li’s 2017 paper, Not All Browsers Are Created Equal: Comparing Web Browser Fingerprintability, examined browser fingerprintability rather than today’s antidetect products. It is background on the issue, not a current product benchmark. Read the paper
