Compare ExpressVPN, Thunder VPN, and Psiphon VPN: Which App is the Best?

Thunder VPN delivers a solid foundation of core VPN features that meet the basic needs of most users. The app's feature set is straightforward and focused on simplicity rather than advanced functionality, which aligns well with its target audience of casual VPN users.

Key features we found most valuable include:

• Unlimited Bandwidth: Unlike many free VPNs that impose data caps, Thunder VPN offers truly unlimited data usage, making it suitable for streaming and heavy browsing
• One-Tap Connection: The interface is designed for simplicity with a prominent connect button that automatically selects the best server
• Global Server Network: Access to servers worldwide for bypassing geo-restrictions and accessing blocked content
• No Registration Required: Users can start using the VPN immediately without creating accounts or providing personal information
• Manual Server Selection: Choose specific server locations for optimal performance
• Minimal Advertising: Much less intrusive ads compared to other free VPNs

However, Thunder VPN lacks many advanced features that users expect from premium VPN services. There's no kill switch to protect against connection drops, no split tunneling to route specific apps through the VPN, and no specialized servers for streaming or torrenting. The server selection is limited compared to premium alternatives.

While the core features work well for basic privacy and geo-unblocking needs, power users will find the feature set limiting. For users who need advanced features like kill switches, split tunneling, or specialized servers, alternatives like Proton VPN offer more comprehensive free tiers, while NordVPN provides extensive advanced features for premium users.

We rate features at 7.5 out of 10—good for basic VPN needs with better user experience than most free alternatives, but lacking the depth that serious users require.

Thunder VPN's security and privacy practices present a mixed picture that raises some concerns for privacy-conscious users. While the app claims to offer secure connections and privacy protection, several factors undermine confidence in its privacy commitments.

Security strengths include:

• Encrypted Connections: The app provides encrypted tunnels for data transmission, protecting users on public WiFi networks
• No Registration Required: Users can use the service without providing personal information or creating accounts
• Basic Privacy Protection: IP address masking and location spoofing for basic privacy needs
• Standard VPN Protocols: Uses established VPN protocols for secure connections
• No-Logging Policy: Claims to maintain a strict no-logging policy

However, some privacy concerns emerge from user feedback and business practices:

• US-Based Developer: The developer is located in the United States, which raises questions about data jurisdiction and potential government access
• No Independent Audits: Unlike premium VPNs, Thunder VPN hasn't undergone third-party security audits to verify its privacy claims
• Data Harvesting Concerns: Some users report concerns about data harvesting, though this isn't explicitly confirmed
• No Transparency Reports: No public transparency reports about government requests or data handling practices
• Free Service Concerns: The completely free model raises questions about how the service is monetized

User reviews reveal mixed experiences, with some users praising the app's privacy features while others express concerns about data collection. The lack of transparency about the service's data handling practices further undermines trust.

For users who prioritize privacy and security, alternatives like Proton VPN offer Swiss-based privacy protection with independent audits and transparency reports, while Windscribe VPN provides Canadian privacy protection with more transparent data handling practices.

We rate security and privacy at 6.0 out of 10—basic security features present but concerns about data handling, jurisdiction, and transparency that compromise trust in the service.
