Psiphon for PC Windows 10/11 — download and install guide (2026)

Psiphon has a native Windows app. You download it as a single .exe file from psiphon.ca — no traditional installation needed, just run the file. It works on Windows 7, 8, 10, and 11, both 32-bit and 64-bit. The latest version as of early 2026 is 186.

What is Psiphon?

Psiphon is a free, open-source censorship circumvention tool developed by a Canadian non-profit. It combines VPN, SSH, and HTTP proxy technologies to route your internet traffic through servers in different countries, allowing access to blocked websites and services.

It was developed specifically for users in countries where certain websites or apps are restricted by government or ISP-level filtering. It is not a privacy VPN in the traditional sense — Psiphon prioritizes access over anonymity, and the company’s privacy policy notes that some anonymized usage data is collected for performance optimization.

Psiphon is funded by grants from organizations like the US State Department and has been used extensively in regions where internet censorship is common.

Is there a native Windows version?

Yes. Psiphon maintains an official Windows client that runs as a portable .exe — meaning it does not write to the Windows registry or require standard installation. You run it directly from wherever you save the file, including a USB drive.

The Windows version is updated regularly. The latest update as of March 2026 is version 186 (released late February 2026).

How to download and install Psiphon on Windows

1. Go to the official site at psiphon.ca
2. Click “Download for Windows” — this downloads a small .exe file (around 10-15 MB)
3. Save the file anywhere on your PC — Desktop, Downloads folder, or a USB drive
4. Double-click the .exe to run it — no installation wizard, it starts immediately
5. Windows may show a security warning since it’s not signed by a major publisher — click “More info” then “Run anyway” to proceed
6. Psiphon connects automatically to find an available server
7. Once connected, your browser is configured to route through Psiphon

When Psiphon connects, it opens your default browser automatically. The connection routes through Psiphon’s server network and allows access to blocked content.

System requirements

How Psiphon routing works

Psiphon uses three protocols and tries them in order based on your network conditions:

1. SSH — Encrypted tunnel through SSH protocol, works on most networks
2. HTTPS — Routes through HTTPS, harder to detect and block
3. HTTP — Unencrypted, used as a fallback when SSH and HTTPS are blocked

The app selects the protocol automatically. You can also set a preference in the Options menu if one method works better on your network.

Psiphon is not a full VPN in the traditional sense — it only routes browser traffic by default. Other applications continue using your regular internet connection unless you enable “Use Psiphon for all traffic” in settings.

Common problems and fixes

Psiphon won’t connect

If Psiphon fails to connect after trying for several minutes, try switching the protocol manually. Open Options (gear icon) and change the tunnel protocol from “Auto” to “HTTPS” or “SSH.” Some networks block specific ports — changing protocols can bypass this.

If you’re on a heavily restricted network (like in a country with deep packet inspection), you may need to use the “Use upstream proxy” option and enter details for a SOCKS or HTTP proxy if one is available.

Connection is slow

Psiphon’s servers can be congested during peak hours. Under Options, you can enable “Egress Region” to select a specific country for exit traffic — choosing a less popular exit region often improves speed.

Windows Defender flags the .exe as suspicious

This is a false positive. Psiphon’s executable is not traditionally code-signed, which triggers Windows security warnings. The source code is public at github.com/Psiphon-Inc. If you’re concerned, download only from psiphon.ca and check the file hash against the one listed on their site.

Only the browser is routing through Psiphon

By default, Psiphon acts as a local proxy and only affects browser traffic. To route all app traffic through it, open Options and enable “Use Psiphon for all traffic.” This requires Psiphon to install a VPN adapter, which may prompt for administrator permission.

Comparison with alternatives

Tor Browser — Focuses on anonymity rather than access speed. Much slower than Psiphon. Better for privacy, worse for streaming.

Lantern — Similar censorship circumvention tool, peer-to-peer based. Free tier has bandwidth limits.

ProtonVPN — Full VPN with privacy focus. Free tier exists with limited server choices. More robust than Psiphon for general privacy use.

Windscribe — Free VPN with 10 GB/month on the free plan. More features than Psiphon but requires account registration.

Psiphon is the better choice specifically for accessing censored content in restricted regions. If you just want general privacy protection, a dedicated VPN service offers better anonymity controls.

FAQ

Is Psiphon safe to use?
Psiphon is open-source and developed by a registered Canadian non-profit. It is not a privacy VPN — the company collects anonymized usage data. It is safe for bypassing censorship but should not be used for sensitive activities requiring full anonymity.

Does Psiphon work on Windows 11?
Yes. The Windows .exe runs on Windows 11 without any modifications.

Is Psiphon free?
Yes. The Windows version is completely free. There is no paid tier for the desktop client.

Do I need to install Psiphon?
No. It runs as a portable .exe — just download and run. Nothing is installed to the system. You can run it from a USB drive.

What’s the difference between Psiphon and a VPN?
Psiphon uses a combination of SSH tunneling, HTTP proxy, and HTTPS proxy. A traditional VPN encrypts all device traffic at the OS level. Psiphon only routes browser traffic by default, though it can be configured to route all traffic.

Summary

Psiphon has a native Windows PC client as of 2026. Download the .exe from psiphon.ca, run it directly without installation, and it connects automatically to bypass content restrictions. It’s free, open-source, and works on Windows 7 through 11. For complete privacy, pair it with or replace it with a dedicated VPN service.
