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, in the API Commons Rate Limits shape.

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

An exhausted limit returns HTTP 429.

This profile was written by API Evangelist and has not been verified against a page the provider published; treat every limit as unconfirmed until a dated transcription replaces it.

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.

Limits

VNC Cloud REST API account
varies
see RealVNC help center (gated)
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.
