AdsPower and Dolphin Anty are both browser-profile platforms used by teams that need isolated browser environments and automation. The useful comparison is less about marketing checklists and more about the underlying browser engines, profile management, Local API capabilities, automation workflow and security model.
For an engineering comparison, the useful questions are which browser engines are available, how the Local API is exposed, what automation interface each product supports, and how much of the workflow depends on the desktop client.
Browser Engine Architecture: SunBrowser & FlowerBrowser vs. Dolphin Core
AdsPower ships two patched engines: SunBrowser (Chromium fork) and FlowerBrowser (Firefox-based). The dual-engine setup is not a gimmick. Firefox’s Gecko has a fundamentally different canvas rasterization pipeline than Blink. Running both means your profile fleet covers two distinct rendering fingerprint spaces, which matters when platforms start correlating engine-specific rendering artifacts across your account clusters.
Dolphin{anty} runs a single Chromium core. Full stop. Dolphin Anty only supports the Chromium-based browser, while AdsPower’s SunBrowser covers Chrome and FlowerBrowser covers Firefox, so you don’t need to switch browser habits. That’s fine until you’re managing 800+ Facebook accounts and suddenly every profile in your fleet has the same underlying Blink rendering signature. Platforms track that pattern.
The practical upside for Dolphin is version discipline. Their team tends to keep the Chromium core tighter and more frequently updated — at least when things are working. We’ll get to what happens when they don’t.
Anecdotal incidents can be useful context, but they are not a reliable way to compare browser platforms. For this comparison, the more useful signal is each product’s documented browser-engine and update model rather than an individual account incident.
Core update cadence isn’t a feature comparison bullet point. It’s your operational risk surface.
Fingerprint Mutation Vectors: Canvas, WebGL, AudioContext, WebRTC
Canvas fingerprinting works by drawing an invisible element and reading back the pixel buffer. GPU driver, OS font rendering, anti-aliasing pipeline — all of it leaves a unique signature in that pixel data. A proper anti-detect browser needs to inject noise at the canvas getImageData and toDataURL intercept points before the call returns to JavaScript. Not after.
AdsPower’s SunBrowser patches this at the Blink layer. Dolphin{anty}’s implementation also operates pre-return. These fingerprints include dozens of parameters: browser type, screen resolution, timezone, installed fonts, Canvas rendering, WebGL specifications, audio context, CPU/GPU information, and more. Platforms use these fingerprints to identify and track users across sessions.
WebGL is messier. The RENDERER and VENDOR strings are the obvious targets — everyone spoofs those. The real detection vector is shader precision behavior. getShaderPrecisionFormat() returns values derived from actual GPU hardware, and those values correlate with the declared RENDERER string. If your spoofer hands a profile an NVIDIA string but the underlying GPU is AMD, the precision format values won’t match, and any halfway-decent fraud model catches it.
AudioContext manipulation is where both tools are doing the same thing: injecting sub-threshold noise into createAnalyser() output to perturb the baseLatency fingerprint. Neither AdsPower nor Dolphin{anty} has a significant edge here based on publicly observable behavior.
WebRTC leaks are still killing people in 2025. Your proxy routes HTTP through the configured exit node fine, but WebRTC STUN requests can bypass proxy settings entirely and expose the host machine IP. Both tools offer WebRTC IP handling settings. Verify them. Test with a fresh profile against an IP leak checker before you deploy anything at scale. Don’t assume the default config is safe.
In independent assessments, AdsPower and Dolphin Anty both fall into the professional tier, achieving 80–90% bypass rates on sophisticated platforms — solid for most production workflows, though behind the top tier that clears 90%+.
Local REST API & Automation: Port 50151 vs. Port 3001
This is where the two tools genuinely diverge for engineering teams.
AdsPower exposes its local REST API on port 50151 (some builds also use 50325 — check your local settings file). The API address is http://local.adspower.net:50325/ or http://localhost:50325/, and the port subjects to the address in settings — check the Cache folder’s local_api file to confirm.
Dolphin{anty} binds to port 3001 by default. By default, the local API uses port 3001; if busy, another port is assigned — check the Health window in Dolphin{anty} to confirm the active port.
Both use the same underlying pattern: start a profile via the local API, get back a WebSocket debugger URL, then connect via Chrome DevTools Protocol. Here’s a production-ready implementation for AdsPower:
import requestsfrom playwright.sync_api import sync_playwrightADSPOWER_API_URL = "http://127.0.0.1:50151/api/v1/browser/start"PROFILE_ID = "profile_dev_99"response = requests.get(f"{ADSPOWER_API_URL}?user_id={PROFILE_ID}").json()if response["code"] != 0: raise Exception(f"API Failure: {response['msg']}")ws_debugger_url = response["data"]["ws"]["puppeteer"]with sync_playwright() as p: browser = p.chromium.connect_over_cdp(ws_debugger_url) context = browser.contexts[0] page = context.new_page() page.goto("https://pixelscan.net/") print(f"Fingerprint Status: {page.locator('#fingerprint-status').text_content()}") browser.close()
For Dolphin{anty}, the pattern is nearly identical: send a GET request to http://127.0.0.1:3001/v1.0/browser_profiles/{PROFILE_ID}/start?automation=1, extract the automation.port from the response, then connect via CDP.
Now for the part nobody puts in the marketing docs.
RAM degradation under load. An idle profile in either tool sits at roughly 180MB. Run continuous automated headless loops — form fills, cookie warming, account interaction sequences — and that footprint climbs. After four hours of continuous execution, you’re looking at 450MB+ per profile due to browser context overhead accumulating in the Chromium renderer process. This isn’t a bug in either tool specifically. It’s Chromium’s memory management behavior under long-running CDP sessions. The fix is forced profile restarts on a schedule, not hoping the GC will catch up.
At 3:00 AM once, a script running 180 concurrent profiles on a 64GB machine just stopped. Not crashed — stopped. The local API daemon on port 50151 had developed a silent socket leak after opening its 150th concurrent profile connection. No error thrown. The daemon was still responding to health checks. But new connection requests were silently queuing and timing out because the OS socket descriptor table was exhausted. The fix was in /etc/security/limits.conf — bumping nofile to 65535 — combined with a connection pool pattern that recycled browser handles rather than opening new ones per task cycle.
Under 50-thread concurrent load, AdsPower’s daemon is more stable. Dolphin{anty}’s local API can start dropping responses in the 40–60 concurrent profile range on Windows, particularly if the host machine is also running the desktop UI. The architectural reason is that Dolphin’s daemon is tightly coupled to the desktop application process — they share the same process tree. AdsPower’s daemon runs more independently. At scale with Dolphin Anty, the key is strict profile–proxy alignment, using the Local API with automation=1 to avoid manual overrides, and keeping scripts human-paced so Anty controls the fingerprint while automation only drives behavior. That advice about “human-paced” scripts isn’t just about detection — it’s about keeping the daemon alive.
Cloud Synchronization and Data Security Models
In July 2022, Dolphin{anty}’s cloud profile storage was breached. On July 18, users encountered a massive service disruption. The team confirmed a large-scale leak from the cloud storage of browser profiles — approximately 15% of total profiles were compromised. Hackers obtained session cookies, enabling them to access any account without passwords or two-factor authentication.
Many users were left with empty crypto wallets. The breach reportedly occurred in the night between July 14 and 15, but users weren’t notified until July 18. A three-day gap between incident and disclosure. For an audience of affiliate marketers with live crypto exchange sessions stored in profiles, that’s not a minor detail.
The attack gave hackers access to user KYC data along with all sessions. They could log into accounts directly — no passwords, no 2FA — exactly like working from logs.
Post-breach, the engineering response was real. After the 2022 incident, developers migrated servers to Amazon infrastructure and implemented two-factor authentication. The team also compensated affected users, which preserved a significant portion of audience loyalty. Additionally, Dolphin Anty has since been building a bug bounty program, replaced IT infrastructure over the past two years, and segmented rights and access controls.
That’s a legitimate recovery arc. The infrastructure changes are real. But the core architectural problem that made the breach catastrophic — storing active session cookies server-side in a way that gave a single database compromise access to live account sessions — that’s a design philosophy question, not just an ops failure.
AdsPower’s stated model is client-side encryption before cloud transmission. The encrypted blob that hits their servers is not the decryptable thing — the key never leaves your device. Whether you verify this claim in practice depends on whether you’re the kind of team that runs mitmproxy between your client and their cloud endpoint. Most teams don’t. But the architectural claim is materially different from “sessions live on our servers.”
For high-value account operations — anything touching financial services, crypto, aged ad accounts with real spend history — the security model matters more than the UX polish.
The Cost-per-Profile Scaling ROI
Dolphin{anty} serves 860,000+ users. Pricing starts at $89/month, providing advanced team collaboration with role-based access control, a powerful automation API, and built-in RPA capabilities.
AdsPower offers a free tier with two profiles, paid plans starting at roughly $5.4/month. AdsPower allows users to start at a lower cost and scale gradually. For teams planning to grow operations over time, it offers a more flexible long-term solution.
The real cost calculation isn’t plan pricing — it’s cost-per-profile at your actual operating scale. At 500 profiles, AdsPower’s per-profile cost is significantly lower than Dolphin’s. At 100 profiles, Dolphin’s flat pricing might actually pencil out better depending on your plan tier.
The break-even math depends on two variables: profile count and team size. Dolphin’s team collaboration features are legitimately well-built. The role-based access, tagging, and profile organization are ahead of AdsPower in UX terms. In Dolphin Anty you can sort profiles not only by name, but also by notes, tags, and statuses — AdsPower lacks this granularity. If you’re running a team where multiple buyers need to hand off profiles without clobbering each other’s state, that matters operationally.
Dolphin Anty is sleek and affordable but missing the depth needed for enterprise use. AdsPower is more complex but built to support larger and more complex workflows with clearer team permission controls.
Hard-Core Engineering FAQ
Q: How do I handle local API connection timeouts when spinning up more than 30 profiles simultaneously?
Don’t fire all 30 start requests in a tight loop. The daemon’s socket listener has a connection queue limit, and on Windows it’s lower than Linux by default. Implement a connection pool pattern: pre-allocate a pool of N browser handles, process tasks against the pool, recycle handles rather than open-close-open. For the start requests themselves, use a semaphore to cap concurrent in-flight API calls to 10–15 at a time, with a 300–500ms delay between batches. If you’re on Linux, bump net.core.somaxconn and your process nofile limit before you start complaining about timeouts — the default socket backlog of 128 will strangle you at scale. For AdsPower specifically, if the daemon on port 50151 starts silently dropping connections, restart the AdsPower application process entirely rather than just retrying the API call; the daemon doesn’t self-recover from descriptor exhaustion.
Q: Why do Facebook cookie imports sometimes drop active sessions when moving between AdsPower and Dolphin{anty}?
The two platforms serialize cookie arrays differently in their JSON profile export format. AdsPower follows a Netscape-style flat array where sameSite values are stored as string enums ("Strict", "Lax", "None"). Dolphin{anty}’s export uses integer encoding for some cookie attributes in certain export versions. When you import an AdsPower export into Dolphin or vice versa, the parser on the receiving end may silently drop cookies with unrecognized attribute formats rather than throwing an error. The session appears to load but the datr and xs cookies that Facebook actually checks for session validity are missing. The fix is to write a normalization pass on the cookie JSON before import — parse both formats into a canonical structure, validate that httpOnly, secure, and sameSite fields are present and correctly typed for the target platform’s expected schema. There’s also an IndexedDB synchronization lag: after cookie import, Dolphin’s profile needs a 2–3 second settle time before the first page navigation or the browser context reads from a partially-flushed IndexedDB state.
Q: Can I run automated headless profiles on a Linux VPS without an X11 display server?
Yes, but the approach differs between the two tools. AdsPower’s SunBrowser daemon supports a --headless flag passed via the local API start call, and on Linux it uses Chrome’s native headless mode (the new --headless=new implementation, not the legacy one). No Xvfb required. Dolphin{anty}’s daemon is more tightly coupled to a display context — on a headless VPS you’ll need to spin up a virtual framebuffer: Xvfb :99 -screen 0 1920x1080x24 & and export DISPLAY=:99 before launching the Dolphin application process. The headless=1 parameter in Dolphin’s API start call doesn’t fully bypass the display requirement on all Linux configurations — it controls the Chrome instance’s headless flag but the daemon itself still wants a display server to initialize. For pure server-side automation at scale, AdsPower’s architecture is cleaner on Linux. If you’re running Dolphin on a VPS, budget the Xvfb overhead into your memory calculations — it’s not zero.
