Compare Proton VPN, Thunder VPN, and VPN Proxy Master: 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.

VPN Proxy Master offers a solid set of features for a free VPN service, with unlimited data access and an extensive server network of 6,700+ servers worldwide. The service includes military-grade encryption, multiple VPN protocols (IPsec, ISSR, OpenVPN, SSR), and support for up to 10 devices simultaneously.

What sets VPN Proxy Master apart is its completely free tier with no data caps or time limits, making it accessible to users who cannot afford premium VPN services. Unlike Proton VPN without ads, VPN Proxy Master relies on heavy advertising. The service offers good server coverage for basic geo-blocking and content access, and the one-tap connection interface makes it easy to use for beginners.

However, the service lacks some advanced features found in premium VPNs, such as kill switch protection, split tunneling, and specialized servers for streaming or torrenting. The free model also means limited customer support and no advanced security features that premium services typically offer.

Compared to other free VPNs like Proton VPN or Windscribe VPN, VPN Proxy Master offers more generous free features but with significant limitations in terms of reliability and user experience. The service provides basic VPN functionality but cannot compete with premium alternatives in terms of advanced features.

Thunder VPN's performance presents a mixed picture that reflects the challenges of maintaining a free VPN service. While the app can deliver fast connections when working properly, reliability issues significantly impact the overall performance experience.

Performance strengths include:

• Fast Connection Speeds: When connected, users report good speeds for browsing and streaming
• Quick Connection Times: The app connects to servers relatively quickly when the connection is stable
• Global Server Network: Access to servers worldwide provides good coverage for geo-unblocking
• Lightweight App: The app itself is relatively small and doesn't consume excessive system resources
• Minimal Advertising: Much less intrusive than competitors, improving perceived performance

However, significant performance issues undermine the user experience:

• Frequent Connection Drops: Users consistently report that connections drop frequently, requiring reconnection
• Inconsistent Reliability: Connection quality varies significantly between sessions and servers
• Must Keep App Open: Users must keep the app window open to maintain connections, which can be inconvenient
• Connection Instability: Many users report that the VPN disconnects after a few minutes of use
• Slow Loading Times: Some users report occasional slow loading times

User reviews reveal a pattern of performance issues, with many users praising the app's speed when it works but complaining about frequent disconnections. The app's focus on user experience over aggressive monetization may be impacting server quality and maintenance.

For users seeking reliable performance, alternatives like Proton VPN offer more consistent free performance with better server maintenance, while NordVPN provides premium performance with dedicated servers and better reliability guarantees.

We rate performance at 6.5 out of 10—good speeds when working but undermined by frequent connection drops and stability issues that create an inconsistent user experience.

VPN Proxy Master's performance is inconsistent, with good speeds when working but frequent connection issues that significantly impact usability. The service offers decent connection speeds and server coverage, but the frequent disconnections and advertising make it difficult to use reliably.

The service works well for basic geo-blocking and content access when connected, but many users report frequent connection drops and the need to manually reconnect multiple times per day. The advertising also impacts performance, making the app slow and unresponsive at times.

The service's performance issues are particularly concerning given the free model. Users expect basic functionality from a free service, but VPN Proxy Master's connection problems make it difficult to recommend over alternatives that offer more stable free tiers with better performance.

Compared to other free VPNs like Proton VPN or Windscribe VPN, VPN Proxy Master's performance is below average. The connection stability issues and advertising make it difficult to recommend over alternatives that offer similar features with better performance and fewer limitations.

Thunder VPN's design philosophy centers on simplicity and user experience, which works exceptionally well for its target audience. The interface is clean, intuitive, and focuses on functionality rather than flashy design elements.

Design strengths we observed include:

• Clean Interface: The main screen features a simple, intuitive layout with the connect button as the focal point
• Clear Visual Feedback: Connection status is clearly indicated with color-coded states (connected/disconnected)
• Minimalist Approach: The app avoids overwhelming users with complex settings or technical jargon
• Consistent Branding: The visual design maintains consistency across different screens
• Accessible Design: Large buttons and clear text make it usable for users of all technical levels
• Minimal Advertising: The app's focus on user experience means less intrusive advertising

The design experience is significantly better than competitors like Turbo VPN and Now VPN, with much less advertising interruption. Users consistently praise the app's clean interface and ease of use, making it one of the most user-friendly free VPNs available.

While the core interface design is solid, some users report that the app requires keeping the window open to maintain connections, which can be inconvenient. However, this is a minor issue compared to the overall design quality.

For users who value a clean, uninterrupted interface, Thunder VPN offers one of the best free experiences available. Alternatives like Proton VPN offer similar design quality with better privacy protection, while Windscribe VPN provides a comparable free experience with fewer restrictions.

We rate design at 8.0 out of 10—excellent design principles with minimal advertising that creates a genuinely user-friendly experience.

VPN Proxy Master's interface is simple and functional, with a clean design that focuses on ease of use. The main screen provides quick access to connection controls and server selection, making it easy for users to connect to the VPN with minimal technical knowledge.

The app's design is straightforward with a dark theme and clear connection status indicators. The server selection process is intuitive, and the one-tap connection feature works as advertised. The interface is generally user-friendly and doesn't overwhelm users with complex options.

However, the design is significantly impacted by excessive advertising that can make the app practically unusable. Many users report that ads interfere with the core functionality, and the app can become slow and unresponsive due to the heavy ad load. The advertising also affects the overall user experience and makes the interface feel cluttered.

Compared to other free VPNs like Proton VPN or Windscribe VPN, VPN Proxy Master's design is basic but functional. The interface works for basic VPN needs, but the excessive advertising significantly detracts from the user experience and makes it difficult to recommend over alternatives with cleaner interfaces.

Thunder VPN's value proposition is significantly better than most free VPNs, offering a genuinely useful free service with minimal advertising and good performance. The app provides excellent value for users who can tolerate occasional connection issues.

Value strengths include:

• Truly Free Core Service: Unlimited bandwidth and server access without time limits or data caps
• No Upfront Costs: Users can start using the VPN immediately without payment or registration
• Unlimited Usage: Unlike many free VPNs, there are no daily or monthly data limits
• Global Server Access: Free access to servers worldwide for geo-unblocking
• No Registration Required: Start using the service immediately without providing personal information
• Minimal Advertising: Much less intrusive than competitors like Turbo VPN and Now VPN

The free tier's value is significantly better than most free VPNs, with minimal advertising and good performance. However, some limitations affect the overall value:

• Connection Stability: Frequent connection drops require reconnection
• Must Keep App Open: Users must keep the app window open to maintain connections
• Limited Advanced Features: No kill switch, split tunneling, or specialized servers

The premium pricing is reasonable ($1.99-$59.99), but the connection stability issues may not justify the upgrade for many users. Premium VPN services like NordVPN and Surfshark VPN offer more comprehensive features and better reliability for similar or lower costs.

For users seeking genuine value, Thunder VPN offers one of the best free experiences available. Alternatives like Proton VPN offer a more generous free tier with better privacy protection, while Windscribe VPN provides a more reliable free experience with fewer restrictions.

We rate value for money at 8.0 out of 10—excellent value for a free VPN with minimal advertising and good performance, though connection stability issues limit the overall experience.

VPN Proxy Master's value proposition is mixed, with the completely free tier offering good value for basic VPN needs, but the advertising and connection issues significantly impact the overall value. The service provides unlimited free access with no data caps, which is generous compared to other free VPNs.

The service offers good server coverage and basic VPN functionality without requiring payment, making it accessible to users who cannot afford premium VPN services. Unlike Proton VPN without ads, VPN Proxy Master relies on heavy advertising. The free tier includes most essential features needed for basic geo-blocking and content access.

However, the service's value is significantly impacted by excessive advertising and connection stability issues. Many users report that the ads make the app practically unusable, and the frequent connection drops reduce the practical value of the free service. The premium subscription is necessary for a usable experience, but the pricing is competitive with other VPN services.

Compared to other free VPNs like Proton VPN or Windscribe VPN, VPN Proxy Master offers more generous free features but with significant limitations. The advertising and connection issues make it difficult to recommend over alternatives that offer more stable free tiers with fewer limitations.

Thunder VPN excels in basic usability with its one-tap connection approach, making it one of the most accessible VPN apps for beginners. The core functionality is genuinely simple and requires no technical knowledge to operate effectively.

Usability strengths include:

• One-Tap Connection: The primary action is as simple as tapping a single button—no configuration or technical setup required
• No Registration: Users can start using the VPN immediately without creating accounts or providing personal information
• Automatic Server Selection: The app handles server selection automatically, removing the complexity of choosing optimal servers
• Clear Status Indicators: Connection status is immediately visible with clear visual feedback
• Cross-Platform Consistency: The interface works similarly across Android and iOS devices
• Minimal Advertising: Much less intrusive than competitors like Turbo VPN and Now VPN

However, the ease of use is somewhat undermined by connection stability issues. Users report that the app requires keeping the window open to maintain connections, which can be inconvenient. Additionally, frequent connection drops require reconnection, which interrupts the user experience.

While the core interface is genuinely easy to use, the connection stability issues compromise the overall user experience. For users seeking a truly hassle-free VPN experience, alternatives like Proton VPN offer a cleaner free tier with better connection stability, while Windscribe VPN provides a more reliable free experience.

We rate ease of use at 7.0 out of 10—excellent core usability with good interface design, but undermined by connection stability issues that require user intervention.

VPN Proxy Master is generally easy to use for basic VPN functionality, with a simple one-tap connection process that requires no technical knowledge. The app's interface is intuitive, and most users can get connected quickly without any setup or configuration.

The service offers automatic server selection and connection, making it accessible to users of all technical levels. The app doesn't require registration or account creation, which simplifies the setup process. The connection process is straightforward and works well when the service is functioning properly.

However, the service's ease of use is significantly compromised by excessive advertising and connection stability issues. Many users report that ads interfere with the connection process, and the app can become slow and unresponsive due to the heavy ad load. The frequent connection drops also make the service frustrating to use.

Compared to other free VPNs like Proton VPN or Windscribe VPN, VPN Proxy Master's ease of use is similar but not significantly better. The advertising and connection issues make it difficult to recommend over alternatives that offer more stable free tiers with fewer limitations.

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.

VPN Proxy Master offers basic security features with military-grade encryption and multiple VPN protocols, but the free model raises significant privacy concerns. The service uses AES-128 encryption and supports various protocols including IPsec, ISSR, OpenVPN, and SSR.

The service claims to have a no-logs policy, but the free model and heavy advertising raise questions about data collection and user privacy. The service is based in Singapore, which provides some legal protection, but the free model means the service needs to monetize through other means, potentially compromising user privacy.

However, the service has faced criticism for privacy concerns, particularly around data collection and the free model. Many users report concerns about the service's data practices, and the heavy advertising suggests significant data collection for targeted ads. The service also lacks transparency about its data practices and privacy policies.

Compared to other free VPNs like Proton VPN or Windscribe VPN, VPN Proxy Master's security practices are questionable. The free model and heavy advertising make it difficult to trust the service with sensitive data, and users seeking privacy protection would be better served by alternatives with more transparent privacy practices.
