Short answer: Shadowfly is a paid proxy-style service that one China travel guide recommends. Its own site, shadowfly.org, lists four plans, a “VLESS protocol with optimized routing” and a “no logs” claim. On the page we read it names no company, address or jurisdiction, and it gives no refund policy, free trial or server locations. We found no independent audit. We did not test the service. Do not use it for anything sensitive unless you can find out who runs it.
This is a review of what can be checked from public pages, not of how the service performs. Information was gathered on October 5, 2026. If Shadowfly has published more since then, the site is the place to look.
What Shadowfly publishes about itself
The plans on shadowfly.org differ in data allowance, speed cap and device count. The prices are shown with a ¥ symbol and the page does not state which currency that is, so the figures below are copied as shown rather than converted.
| Plan | Data and speed | Devices | Monthly | Yearly |
|---|---|---|---|---|
| Essential Explorer | 50 GB, 25 Mbps | 1 | ¥9.99 | ¥101.90 |
| Streaming Starter | 150 GB, 50 Mbps | 3 | ¥14.99 | ¥152.90 |
| Power Surfer | 500 GB, unlimited speed | 5 | ¥34.99 | ¥356.90 |
| Limitless Legend | 100,000 GB, unlimited speed | Unlimited | ¥59.99 | ¥611.90 |
The site also lists quarterly and half-year prices, says the service uses the “VLESS protocol with optimized routing,” and names these platforms: Android, iOS, macOS, Windows, Linux and routers. Its headline claim is “No limits, no logs, no censorship.”
What the site does not say
On the page we read, Shadowfly does not state:
- a company name, address or jurisdiction
- a refund policy
- whether there is a free trial
- where its servers are
Those are the details that let you judge who would hold your connection data and what you could do if something went wrong. Their absence does not prove bad faith, but it is a reason to be careful.
What third parties say, and where it does not match
A China travel guide on chinaready.org describes Shadowfly as built on the Shadowsocks protocol, reliable for China and a bit more technical to set up than Astrill. The same page says its picks are not affiliate picks, but it gives no prices, company details, audits or test method for Shadowfly beyond citing user reports.
That description does not line up with the official site, which names VLESS rather than Shadowsocks. They are different protocols. Either the guide is out of date, the service offers more than one, or one of the two is wrong. We cannot tell which.
Why a no-logs claim is not enough
Almost every VPN and proxy service says it keeps no logs. The claim only means something when you can tell who is making it and when someone independent has checked it. For Shadowfly we found neither: no named operator on the page we read, and no public audit from a recognized firm. For comparison, our Proton VPN review and best VPN comparison show what published audits and named companies look like.
China, legality and practical risk
The only recommendation we found for Shadowfly is for use behind the Great Firewall. Whether and how VPN use is allowed there is a legal question, and tools get blocked without notice. Our guide to Proton VPN in China covers the legal situation and how to prepare, and stealth VPN explained covers how obfuscation works and where it falls short.
What to check before paying any unaudited service
Look for a named company and a registered address, a written refund policy, a privacy policy that says what is kept and for how long, and a payment method you can dispute if the service disappears. Start with the shortest plan rather than the yearly one. If none of that is available, treat the service as disposable and do not use it for banking, work accounts or anything else you cannot afford to expose.
What we did not do
We did not buy a plan, install the app, measure speed or test whether it unblocks anything. We also did not contact Shadowfly. This page will be updated if the operator publishes company details or an independent audit.
Frequently asked questions
Is Shadowfly legit?
We cannot confirm that either way. We found no named operator and no audit, which is a reason for caution, not proof of bad faith.
Does Shadowfly use Shadowsocks or VLESS?
Its own site says VLESS. A third-party guide says Shadowsocks. We could not reconcile the two.
Is Shadowfly safe to use in China?
We have no evidence on its reliability or safety there. The only China-specific claim we found is in a third-party guide that does not publish its test method.
Is there an audited alternative?
Providers with published audits exist, and our comparison lists them with the sources behind each claim. Whether they work in China at a given moment is a separate question.
