VX DocsAutomatic Node Selection
Latency-based automatic node selection (Pro)
Pro feature — Automatically pick the best node from a group based on latency tests and health checks.
Proxy Selector Modes
| Mode | Behavior |
|---|---|
| Manual | You choose a single node or balance across selected nodes |
| Auto | VX periodically tests nodes and switches to the best available |
Auto Selection
In auto mode, VX runs RTT/latency tests against configured nodes and selects the fastest healthy one. If the current node degrades, the selector switches automatically without disconnecting you.
Configure:
- Test interval and timeout
- Which subscriptions or tags participate
- Fallback behavior when all nodes fail
Manual Multi-Node (Pro)
Manual mode also supports selecting multiple nodes with a balance strategy:
- Random — Distribute connections randomly
- Round robin — Rotate through nodes
- Least latency — Prefer the fastest node per connection
Free Tier
Free users can use manual single-node selection only. Upgrade to Pro for auto selection and multi-node balancing.
