AppSignal vs SoftEther VPN
A side-by-side editorial comparison of AppSignal and SoftEther VPN — release velocity, themes, recent moves, and the top alternatives to consider.
AppSignal vs SoftEther VPN: at a glance
What is AppSignal?
AppSignal links incidents from GitHub and gives its MCP server cleaner metric series.
AppSignal spent late October on tracing: the service map left its feature flag, traces link to host metrics and deploys, and cross-app services show by name. November adds two connection points: pasting an incident URL into a GitHub issue or PR now links it back to the incident, and the AppSignal MCP returns metric time series in a format AI agents read more accurately. A batch of fixes for deploy, host and pod pages rounds it out.
What is SoftEther VPN?
SoftEther returns after 16 months with Windows ARM64 support and a pile of fixes.
SoftEther 5.2.5189 is the first 5.x release since July 2025. It adds Windows ARM64 support with an ARM64 Neo6 driver, restores kernel-mode NAT, adds a configurable DHCP discover timeout and a Turkish translation, and fixes memory leaks, a dangling pointer and Linux password input. Builds can now disable the post-quantum OQS library added in 5.2.5188.

◆ Current state
AppSignal spent late October on tracing: the service map left its feature flag, traces link to host metrics and deploys, and cross-app services show by name.

A batch of fixes for deploy, host and pod pages rounds it out.
◆ Where it's heading
The product is stitching its views together and exposing them to the tools developers already use, GitHub on one side and AI agents via MCP on the other. Each release removes a step between seeing a problem and acting on it.
◆ Prediction
Expect more MCP tools or outputs aimed at agents, such as trace or incident data, following the metric series change.
SoftEther VPN
2.5INFRA · APIS
SoftEther returns after 16 months with Windows ARM64 support and a pile of fixes.
◆ Current state
SoftEther 5.2.5189 is the first 5.x release since July 2025. It adds Windows ARM64 support with an ARM64 Neo6 driver, restores kernel-mode NAT, adds a configurable DHCP discover timeout and a Turkish translation, and fixes memory leaks, a dangling pointer and Linux password input. Builds can now disable the post-quantum OQS library added in 5.2.5188.
◆ Where it's heading
The 5.x line moves slowly and in batches, with community contributors doing most of the work. After 5.2.5188 added hybrid post-quantum key exchange, this release is about platform reach and stability rather than new protocol features.
◆ Prediction
The cadence suggests a long gap before the next tag; the entries give no sign of another protocol-level change soon.
