# freesky: a Chinese-language index page for proxy client downloads, not a codebase

> One README, one html directory, and a page that has tracked Freegate and Ultrasurf builds for years. Worth reading as a release bulletin, with a clear eye on what it does not license.

## What the repository contains: one README and an html directory

The whole tree is two entries, `README.md` and `html/`. There is no source code, no build system, no test suite and no configuration. The language GitHub assigns to the repository is HTML, which reflects that `html/` directory rather than any program. This is a landing page that happens to live in a Git repository instead of on a web host, and the README explains why it is there: the page is the stable address, and the README tells readers to bookmark the GitHub URL so they find the current version when a link goes dead.

That matters for how you read everything else below. Nobody maintains this by deploying a site, and nobody reviews a diff here in the sense a code reviewer would. The maintenance work is refreshing a list of version numbers and making sure the outbound links still resolve. The repository is not archived, the default branch is `master`, and the last push was on 2026-08-21, so it is being touched, even though 2,299 stars and 310 forks would suggest a far larger project than the contents justify.

The README is entirely in Chinese, and it is written for a specific audience: users inside mainland China's network environment who need the pages to keep working when domains are blocked. Much of it is not documentation but pointer material, including a block of links to video features and essay-length articles that have nothing to do with the software. Read past those to the download index.

## The two programs the page actually documents

Roughly two thirds of the content covers two Windows clients, and it helps to know who makes them, because the page is careful to credit each. Freegate is developed by Dynamic Internet Technology and described as a free proxy with high-strength encryption, optimised for mainland China's network conditions. Its current desktop version is 8.05, released 2025-08-17, distributed as a single EXE that runs on the full Windows XP through 11 range in both 32-bit and 64-bit form. Linux and macOS users are pointed at Wine or a Windows virtual machine rather than a native build.

Ultrasurf, usually called Wujie, is from UltraReach Internet Corp and is built on a technology platform the page calls GIFT. Its current Windows release is 22.11, from 2025-03-18. The page attaches two pieces of outside credibility to it: a WIRED magazine description of it as one of the most important free speech tools on the network, and a 2007 Harvard study naming it the most effective of the tools surveyed. Both claims are about a product version many years old, so they describe a historical reputation rather than the current binary. It also reports more than 110,000 users by 2011.

The page's own comparison is blunt: on ease of use, speed, stability and safety, Freegate and Ultrasurf both rank among the best-performing tools available. Its stated advantage for Ultrasurf is cross-platform reach, with a Firefox add-on for Mac and Linux that needs no manual proxy configuration, plus Android builds. Freegate's advantage, implied by the emphasis on it, is a single-file Windows client that configures itself.

## Version dates that run ahead of the repository history

Here is where a reader should slow down. The README lists build dates that are recent: Freegate 8.05 from 2025-08-17, the Freegate Android VPN at 1.7 from 2026-01-16, the nthLink Android app at 7.1.0 from 2026-06-23, and Ultrasurf 22.11 from 2025-03-18. Older entries are kept alongside them, including the Freegate Android 5.0 build from 2021-03-22, Ultrasurf's Android client at 3.0.6 from a 2023-11-18 Google Play release, and Wujie Yidiantong 5.0 from 2021-05-04.

The GitHub release history does not corroborate any of these dates. There is exactly one release, tagged `software`, published 2015-08-12, and its body is three lines long: it names Freegate 7.54 and Ultrasurf 15.01, then tells readers to visit the GitHub homepage for the latest version. So the two records disagree by more than a decade in one direction and by nothing at all in the other, since a README edited in 2026 produces no corresponding release event.

Both facts can be true at once, and the resolution is mundane: the README is the release channel and the tag is a relic. What the mismatch does mean is that you cannot use the Releases tab to check what was distributed when, and you cannot diff a version bump the way you would in a code repository. If the exact provenance of a binary matters to you, this page cannot supply it.

## Platform coverage, including the two platforms it barely covers

The index is organised by platform, and the asymmetry is the interesting part. Windows has Freegate 8.05, Ultrasurf 22.11 and the current Psiphon 3 build. Android has Ultrasurf VPN 3.0.6, Wujie Yidiantong 5.0, Freegate VPN 1.7, Freegate Android 5.0, the nthLink build and an English-language Ultrasurf mobile client at 1.1.3 marked as a test build.

macOS and Linux get one line each, and neither is a current release. macOS offers a Ultrasurf test build numbered 18.07a, and Linux offers a Ultrasurf Linux VPN test build at the same 18.07a number. Compare that with the 22.11 Windows figure in the same document and the gap is obvious. A Mac or Linux reader is being pointed at a build roughly four major versions behind the Windows one, and the page does not claim otherwise.

The Freegate section does offer a workaround for those users, which is to run the single Windows EXE under Wine or inside a Windows virtual machine. It also explains the proxy behaviour per browser, which is the sort of detail that saves an afternoon: Freegate launches and opens the system IE or Edge browser, Chrome and Edge pick up the system proxy automatically, and Firefox users have to select the use system proxy settings option in network configuration themselves. On Android, the Freegate VPN app supports a global proxy with common mainland apps excluded, and the exclusion list is editable from a settings menu in the app.

## The troubleshooting advice is the real content

The most useful paragraph in the README addresses a specific failure: a user on the default channel seeing a message telling them blocking is severe and to wait five to fifteen minutes. The page gives three responses. Download an older version of Freegate or Ultrasurf and try that, because earlier builds sometimes locate a server faster and hold a more stable connection. Switch to the F or M channel, a detail the page links to a getting-started tutorial rather than explaining inline. Or use a different tool entirely, naming Psiphon 3 and nthLink.

That is operational knowledge, not a software description, and it is the clearest signal about what this repository is for. It exists to answer the questions that a chat group or forum thread would otherwise answer, and to do so without search results. The README is explicit that if the primary download links will not open, there is a fallback set on Amazon S3, and that if neither works the cause is almost always active blocking that clears on its own after a while.

Two structural details are worth noting for anyone planning to rely on it. Download links go through a CloudFront distribution with query-string identifiers per link type, and the page also references green iPPOTV television downloads and a forum, neither of which has anything to do with the two main clients. The number of unrelated links on the page is high enough that reading carefully rather than clicking is the sensible approach.

## No license, one ancient tag, and no checksums anywhere

The repository has no license field at all, and there is no LICENSE file in the tree. That is a meaningful absence for a repository that redistributes nothing itself but points at binaries that other people built, because it means nobody has stated any terms for the page itself. The single 2015 release reinforces that this was set up as a pointer rather than a distribution point.

What is missing entirely is verification. No SHA-256 digest, no detached signature and no vendor checksum appears anywhere in the README for any of the listed builds. Every download link resolves through a third-party redirect to a file hosted elsewhere, so the chain from this page to the bytes you run has an unverified middle. That is a property of the whole category rather than a criticism aimed here, since link indexes for this kind of software rarely publish checksums, but it does mean the page cannot be the place where you establish a binary is genuine.

A sensible division of labour follows. Use this page for what it is good at, which is telling you which build number is current for each platform and what to do when a link or a channel fails. Get the binary from the vendor's own distribution, compare it against a hash published by the vendor if one exists, and treat the specific version numbers here as dated pointers that were accurate at the last push on 2026-08-21 rather than as a live feed.

## Conclusion

There is no software here to evaluate, and that is the honest first fact. The repository is a link index: a long README in Chinese pointing at download pages for Freegate, Ultrasurf, Psiphon and nthLink, plus an html directory whose contents are not described anywhere in the README. What it does well is currency. The version numbers and release dates it lists are current to 2026, and the troubleshooting advice about blocked channels and slow servers is the kind of thing that only exists because someone kept answering the same questions for years. What it leaves open is the part that matters for anyone considering installing a binary from a link farm: there is no license file, the release history on GitHub stopped at a single 2015 tag that just points back at the homepage, and no checksum or signature is published for any download. Read it as a way to learn which build is current, then get the binary from the vendor's own channel and verify it there.

## FAQ

### What is the sglfree/freesky repository for?

It is a link index rather than a codebase. The tree holds only README.md and an html/ directory, and the README is a Chinese-language page listing download links for Freegate, Ultrasurf, Psiphon and nthLink, with current version numbers and troubleshooting notes. Nothing is built or run from the repository.

### Which version of Freegate and Ultrasurf does the page list as current?

Freegate 8.05 from 2025-08-17 and the Freegate Android VPN at 1.7 from 2026-01-16. For Ultrasurf it lists Windows 22.11 from 2025-03-18, the Android client at 3.0.6 from a 2023-11-18 Google Play release, and older Wujie Yidiantong 5.0. macOS and Linux are offered only a test build numbered 18.07a.

### Can I use Freegate on macOS or Linux?

The page points macOS and Linux users at running the single Windows EXE under Wine or inside a Windows virtual machine, and it offers no native build for either platform. Ultrasurf has a Firefox add-on for Mac and Linux, and the page credits Ultrasurf with broader cross-platform support than Freegate.

### What should I do if the download links in the README will not open?

The README states that if the primary links fail you should try the fallback set hosted on Amazon S3, and that if every link is dead the cause is usually active blocking that clears after a period. It also advises switching from the default channel to the F or M channel, or trying an older build, or using a different client such as Psiphon 3 or nthLink.

### Does the repository publish checksums for the builds it links to?

No. No hash digest or signature appears for any listed version, and there is no LICENSE file in the repository. The README itself notes that when links cannot be opened, users should star the repository or bookmark the GitHub URL to keep track of updates, which is the page's own answer to how it stays current.
