Networking
Open source VPN protocol with a commercial Access Server product priced per simultaneous connection
- From

- Rated
- -
The short version
- Each has a real cost: Jaeger tracing is only as good as the instrumentation, and partial instrumentation produces misleading gaps; OpenVPN open source OpenVPN, while free, requires real technical skill to configure, secure and maintain without the Access Server admin layer
- They diverge on capability: Jaeger covers Distributed trace search, OpenVPN covers Open source core.

Where they differ
Only the attributes on which Jaeger and OpenVPN actually diverge.
Identical on both: starting price (Free), free tier (Yes), user rating (Not yet rated).

What people use each for
The jobs each tool is most often brought in to do.
Jaeger
- Finding which service in a request path causes the latencynot OpenVPN
- Understanding real service dependencies rather than the diagram on the wikinot OpenVPN
- Debugging failures that only appear under production traffic patternsnot OpenVPN
OpenVPN
- A technical team wanting a fully free, self-configured VPN server using the open source protocol without any vendor relationshipnot Jaeger
- A small business wanting a supported, easier-to-administer VPN server, willing to pay per concurrent connection rather than per employeenot Jaeger
- An organisation with more staff than typical concurrent VPN usage, since Access Server bills only active simultaneous connections, not total accountsnot Jaeger
- An IoT or large-scale deployment needing custom Enterprise pricing above 2,000 connectionsnot Jaeger
Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Jaeger
- Tracing is only as good as the instrumentation, and partial instrumentation produces misleading gaps
- Storage is the real operational cost: high-volume tracing on Elasticsearch or Cassandra is a cluster to run and pay for
- Traces alone, without correlated metrics and logs, leave you switching between tools during an incident
OpenVPN
- Open source OpenVPN, while free, requires real technical skill to configure, secure and maintain without the Access Server admin layer
- Per-connection billing on Access Server means usage spikes, such as an all-hands remote day, can push simultaneous connections over a licensed limit and block new connections until usage drops or the plan is upgraded
- OpenVPN's traditional hub-and-spoke architecture routes traffic through a central server, unlike mesh VPN tools like Tailscale or NetBird that establish direct peer-to-peer connections where possible, which can add latency
- Client configuration and certificate management for the open source version is more manual and error-prone than newer VPN tools with zero-config onboarding
- Access Server pricing above the Growth tier reverts to custom Enterprise quoting, so very large deployments lose the pricing transparency of the lower tiers
- The protocol's throughput is generally lower than newer kernel-integrated protocols like WireGuard under equivalent conditions, which matters for high-bandwidth use cases

Questions people ask
- Is Jaeger or OpenVPN better?
- Neither clearly leads. Jaeger starts at Free and OpenVPN at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, Jaeger or OpenVPN?
- Jaeger starts at Free and OpenVPN at Free.
- Does Jaeger or OpenVPN run on more platforms?
- Jaeger runs on Linux, Kubernetes, Docker. OpenVPN runs on Linux, Windows, macOS, iOS, Android.
- Can I use Jaeger for free?
- Both have a free tier, so you can try either at no cost before committing.
- What is Jaeger best used for?
- Jaeger is most often used for finding which service in a request path causes the latency, understanding real service dependencies rather than the diagram on the wiki, debugging failures that only appear under production traffic patterns. Of those, finding which service in a request path causes the latency and understanding real service dependencies rather than the diagram on the wiki are not what OpenVPN is typically brought in for.
- What can Jaeger do that OpenVPN cannot?
- Jaeger covers Distributed trace search, Dependency graph, Adaptive sampling, Pluggable storage. OpenVPN covers Open source core, Access Server admin UI, Per-connection licensing, Free tier.
Answered from the vendors’ own pages
Jaeger: Is Jaeger free?
Yes, open source and CNCF-graduated. Costs are the storage backend you run.
OpenVPN: Is OpenVPN free?
The open source protocol and software are free under the GPL; Access Server, the commercial packaged product, charges per simultaneous connection beyond a free 2-connection tier.
Jaeger: Do I use Jaeger or OpenTelemetry?
Both, usually. Instrument with OpenTelemetry and use Jaeger to store and query the traces.
OpenVPN: What counts as a connection for billing purposes?
A simultaneously active connected device, not a registered user account or total device count; unlimited accounts and devices can be created but only the licensed number can be connected at once.
Jaeger: Does Jaeger handle metrics and logs?
No. It is a tracing system. Metrics and logs need Prometheus, Loki or an equivalent.
OpenVPN: How does OpenVPN compare with WireGuard-based tools like Tailscale?
OpenVPN uses a traditional hub-and-spoke VPN architecture rather than the mesh, peer-to-peer approach used by newer tools like Tailscale or NetBird.
