Accelerators, VPNs, and proxies can look similar, but they differ in how they route traffic, what they encrypt, and which applications they support. This guide explains those differences so you can compare privacy, performance, pricing, and platform compatibility.
Accelerator vs VPN vs Proxy
People generally use these tools for three different needs: protecting traffic on untrusted networks, improving routing for selected applications such as games, or directing configured application traffic through a proxy. A VPN typically creates an encrypted connection between a device and a VPN server, while an accelerator or proxy may handle only selected traffic. The exact encryption scope and supported applications depend on the product.
How to Evaluate Third-Party Proxy Services
Third-party proxy subscription services vary widely in security, reliability, support, and refund practices. Before using one, review who operates the service, what traffic is encrypted, what data is logged or shared, how long prepaid balances remain valid, and whether the service complies with the rules that apply where you live. Avoid services that do not clearly identify their operator or publish understandable privacy and refund terms.
About Third-Party Network Utility Apps
Shadowrocket is a third-party iOS network utility. Its availability, supported configurations, pricing, and terms are controlled by its developer and the App Store. If you choose to use a third-party network utility, obtain it through an official store listing, follow the developer's documentation, review its privacy practices, and comply with the rules that apply where you live.
How Free Services Are Funded
Free services use different business models. Some offer a limited free tier supported by paid subscriptions; others use advertising or process data for stated purposes. Before choosing a service, review its privacy policy, third-party sharing disclosures, encryption scope, speed and data limits, support options, and how to delete your data. Do not assume that every free service uses the same model.
What to Verify Before Choosing a Service
- Network compatibility. Check whether the service supports the devices and ordinary network environments you use. Connection quality can vary by ISP, location, time, and local network conditions.
- Performance evidence. Compare measurements collected under conditions similar to your own. Speed, latency, jitter, and loss can vary by device, route, server load, destination, and test method.
- Data minimization. Account registration can increase the amount of information a provider holds. Check whether the service requests only the data needed for the stated purpose and explains retention, sharing, and deletion.
- Clear terms. Review pricing, free-tier limits, advertising practices, privacy disclosures, platform support, refund conditions, and customer-support options before choosing a service.
RelyVPN Privacy and Performance Features
RelyVPN combines encrypted connectivity with optional performance features in one app.
- TLS 1.3 encryption. RelyVPN uses TLS 1.3 to protect supported traffic in transit between the app and the service. Encryption does not guarantee availability on every network.
- QUIC protocol and BBR Max congestion control. These technologies are designed to manage throughput and latency. Depending on the user's device, ISP, route, server load, and time of day, the connection may support web browsing, video, interactive applications, and calls at different quality levels.
- Optional game mode. The game mode uses a different balance of routing, throughput, and latency features. Actual results depend on the network and game environment.
- Current free tier. At the time of publication, the free tier does not require account creation. It includes a one-time 300 MB allowance without the free-tier 160 kbps cap; after that allowance is used, the connection is limited to 160 kbps. Current availability, advertising practices, features, and limits are described on the pricing and privacy pages and may change under the applicable terms.
- Published platforms. RelyVPN currently publishes apps or installers for iOS, Android, macOS, Windows, and Apple Vision Pro as listed on the download page. Platform availability and feature parity may change.
The app combines encrypted connectivity, routing choices, and an optional game mode. Available features depend on platform, version, network, and plan.
Game Acceleration and Network Conditions
Game traffic is sensitive to latency, packet loss, jitter, routing, and server load. TCP and QUIC handle loss and stream delivery differently, but real performance depends on the complete implementation and network path. When comparing services, review measured latency and loss under conditions similar to your own rather than assuming that one protocol guarantees a result.
QUIC Stream Multiplexing and Connection Recovery
QUIC supports independent streams and connection migration features that can reduce some forms of head-of-line blocking and reconnection delay. The benefit depends on the application, implementation, packet loss, route, and network conditions. Encryption protects traffic in transit but does not guarantee that an ISP will not apply network-management policies.
BBR and BBR Max
RelyVPN uses BBR Max for throughput-oriented traffic and standard BBR in its game mode to prioritize a different balance between throughput and latency. Actual download speed, latency, jitter, and bufferbloat depend on the user's ISP, route, device, server load, and test method. No specific speed or ping is guaranteed.
CN2 GIA Routing Options
Some RelyVPN game nodes may use CN2 GIA routing. Routes, hops, latency, congestion, and packet loss can change by ISP, destination, time, capacity, and network events. The presence of a CN2 GIA route does not guarantee a specific path or performance result.
Node Recommendations
RelyVPN can probe available nodes and recommend an option with a lower measured latency at that time. Measurements and routes can change, and the selected node may not remain the lowest-latency option.
What Game Mode Is Designed to Do
Game mode is designed to reduce latency variation and reconnection delay where network conditions allow. Packet loss, jitter, congestion, route changes, game servers, and the user's ISP can still affect play.

FAQ
What is the difference between an accelerator, a VPN, and a proxy?
A VPN typically routes device traffic through an encrypted connection to a VPN server. An accelerator focuses on routing or performance for selected applications, while a proxy forwards configured traffic. Encryption scope, privacy practices, and application support vary by service.
Are third-party proxy services safe?
Safety varies by provider. Review the operator, encryption scope, privacy policy, support, refund terms, and local requirements before using a service. Do not assume that price alone indicates security or reliability.
What is Shadowrocket?
Shadowrocket is a third-party iOS network utility. RelyVPN does not operate or support it. Check the developer's official App Store listing and documentation for current availability, features, pricing, and support.
What should I check before using a free service?
Review how the service is funded, what data it collects or shares, which traffic is encrypted, whether ads are shown, what limits apply, and how support and data deletion work. Compare the published terms rather than relying on the word “free” alone.
How does RelyVPN's current free tier work?
At the time of publication, RelyVPN offers a free tier that does not require account creation. It includes a one-time 300 MB allowance without the free-tier 160 kbps cap; after that allowance is used, the connection is limited to 160 kbps. Current availability, advertising practices, features, and limits are described on the pricing and privacy pages and may change under the applicable terms.
Can an accelerator be used for gaming?
Some services include game-focused routing features. RelyVPN's game mode uses QUIC, BBR, and optional routing choices designed to manage latency and reconnection delay. Actual performance depends on the device, ISP, route, server load, game server, and network conditions.
