Vnc Rate Limits

RealVNC does not publish numeric rate-limit thresholds for the VNC Cloud REST API or VNC Developer SDK. Account-management API access is gated by subscription tier (Plus and above), and session-level limits are governed by per-tier active-connection and managed-device quotas in the plans artifact rather than per-second request ceilings. Live RealVNC help center pages return 403 to crawlers; specifics must be retrieved authenticated.

Vnc Rate Limits is the machine-readable rate-limit profile for VNC on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 2 rate-limit definitions, measuring varies and concurrent_connections.

The profile also includes 2 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include Remote Access, Remote Desktop, VNC, and Rate Limiting.

Numeric thresholds not publicly documented; retrieve from authenticated help center.
Active Connection Quota subscription
concurrent_connections
see plans artifact (1 / 3 / 5 / unlimited per tier)
Connection concurrency is enforced by subscription tier, not by request-rate throttling.

Policies

Tier-Bound Capacity
The primary enforcement surface is per-tier active connections and managed-device count, not per-second request rate. Upgrades are made by changing subscription tier.
Backoff and Retry
Clients of the VNC Cloud REST API should implement exponential backoff with jitter on 429 responses.
