The Complete Guide to the SingLink Beta Protocol

What Beta Is, and What It Is Not

SingLink Beta is one of SingLinkVPN's own production protocols, built with a clear focus on high-speed connections. It is not a beta build of the client software, and it is not a stripped-down or crippled variant of a "real" protocol — Beta is fully supported and actively maintained. It simply prioritizes speed over the goals that shape SingLink 2.0, such as stability, cross-platform consistency and connection recovery.

Beta is available on every plan, making it the only protocol that spans the full range from the Free Plan up to Rich. That is a large part of why it is often thought of as an "entry-level" protocol — but entry-level does not mean under-resourced in every case. Under the same protocol name, free nodes and paid-tier nodes draw from different resource pools; paid plans use high-performance resources allocated specifically to that tier.

• What it is: one of SingLinkVPN's in-house protocols, fully supported and actively run, built for speed
• What it is not: not a beta build of the client, and not a deliberately limited variant
• What it is not for: large-scale transfers, high-concurrency or enterprise workloads are better served by SingLink 2.0 (Pro and above)

Where Beta Sits Among SingLink's Four Protocols

SingLinkVPN currently maintains four in-house protocols: Beta, Sola, Mini and SingLink 2.0. Each serves a different combination of needs, so there is no single "best" protocol overall — only the one that matches the current workload and what the plan allows.

Beta is built for speed and everyday use. SingLink 2.0 is the formal protocol generation that emphasizes stability, cross-platform consistency and recovery after disconnection, and it is available mainly on Pro and higher plans. Sola and Mini address other needs — unlocking features and lighter-weight connections respectively — and their specific characteristics are described within the client itself rather than repeated here.

A simple way to choose is in two steps: first confirm the current plan supports the protocol, then match the protocol's strengths to the task at hand. Everyday browsing is usually well served by Beta. Workloads that need higher stability or sustained large transfers should lean toward SingLink 2.0 where the plan allows it.

How the Speed Ceiling Relates to Plan Tier

The Beta protocol's connection speed ceiling rises with membership tier, up to a maximum of 1 Gbps. In other words, the same protocol and the same connection method can reach a higher bandwidth ceiling on a higher plan — the protocol itself does not change behavior between tiers; what changes is the scale of resources allocated to that tier.

Moving up from the Free Plan through Fast, Plus, Pro, Max and Rich increases available node resources and the bandwidth ceiling, not the set of protocols on offer (the Free Plan remains Beta-only regardless of tier comparisons). Actual throughput is also shaped by current node load, local network quality, carrier throttling and time of day. The 1 Gbps figure is a ceiling that can be reached under good conditions, not a number guaranteed at every moment.

Live bandwidth figures for each plan are shown in the client itself. This page describes the structural relationship — that the ceiling rises with tier — rather than listing specific numbers that shift with node allocation.

Workloads Beta Suits, and Ones It Does Not

Beta is well suited to everyday web browsing, social media, messaging, email, HD video streaming, light gaming and general-purpose downloads — workloads with moderate, mostly steady traffic rather than sustained bulk transfer. Because these tasks rarely demand extreme stability guarantees, Beta's speed-first design translates into faster connection setup and quicker content loading.

Beta is a weaker fit for continuous large-file downloads, workloads that run around the clock in enterprise settings, and anything that depends heavily on connection recovery or strict cross-platform consistency. Those cases are better matched to SingLink 2.0, provided the current plan supports it (Pro and above).

• Good fit: browsing, social media, messaging, HD video, light gaming
• Poor fit: sustained large-file transfers, 24/7 enterprise workloads, workloads requiring maximum stability

How Beta Behaves on the Free Plan

The Free Plan can use Beta protocol nodes — and only Beta protocol nodes. That is the core difference in protocol access between the Free Plan and every paid tier, and it is the most direct answer to "what protocol can I use on the free plan?"

Free nodes are a shared, limited resource. They serve the entire population of free users at once, so available bandwidth and node capacity fluctuate with real-time demand across that user base; during peak periods, speeds can dip or individual nodes can become slower to connect. Paid tiers (Fast and above) draw from high-performance resources allocated specifically to that tier and are not shared with free nodes, which is why paid performance tends to be more consistent.

None of this means the Free Plan is unusable — it means the Beta experience on the Free Plan will vary with shared-resource conditions. Anyone whose daily use depends on consistent speed should consider a paid tier for access to a dedicated resource pool.

How to Select a Beta Node in the Client

In the SingLinkVPN client, protocol information is normally shown in the node list or in a node's details. The typical steps to select a Beta node are: open the client and sign in, go to the node list, filter by protocol or check the protocol label on a node's details, choose a node labeled Beta, then tap connect.

In smart mode, the client may automatically choose a protocol and node based on latency, availability and what the current plan allows. To connect through Beta specifically, switch to manual mode first, then follow the same node-selection steps.

• Open the client and sign in to the account
• Go to the node list and filter by protocol, or check the protocol label in a node's details
• Select a node labeled Beta
• Tap connect and wait for the connection to establish

Exact menu locations can shift between client versions, so treat the running client's interface as the source of truth.

Troubleshooting a Beta Node That Will Not Connect

When a selected Beta node fails to connect, the cause is usually local network conditions or resource pressure during a peak period, not a fault in the protocol itself. Work through the following steps in order:

These steps resolve or work around most connection failures. If the problem persists, note the node name, the time it occurred and the exact error message before contacting support, since that detail speeds up further diagnosis.

• Confirm the account's plan is active and that plan has protocol access to that node
• Switch to a different Beta node on the same protocol — free nodes can be temporarily unavailable at peak times
• Check the local network connection, and try switching between Wi-Fi and mobile data
• Restart the client or sign in again to refresh node and protocol configuration
• Confirm the client is updated to the latest version
• If the node still will not connect, contact official support with the node name, the time and the error message
