Stackblitz Rate Limits

StackBlitz limits WebContainer API sessions to 500 per month for commercial plan customers; open source use is free without session caps; enterprise licenses required for production for-profit use beyond included quotas.

Stackblitz Rate Limits is the machine-readable rate-limit profile for StackBlitz on the APIs.io network, in the API Commons Rate Limits shape.

It captures 2 rate-limit definitions, measuring sessions_per_month.

Limit state is signalled in the retryAfter response header, and 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 response codes documented for throttled.

Tagged areas include Rate Limiting, WebContainers, and Developer Tools.
