Brightdata Rate Limits

Bright Data enforces per-zone and per-account concurrency and request-rate limits rather than a single global quota. The managed scraping APIs (Web Unlocker, SERP, Web Scraper) and the Scraping Browser have concurrent-request / concurrent-session ceilings that scale with the account plan and can be raised on request. Proxy zones are constrained primarily by bandwidth and concurrency. Specific numeric limits are configured per zone in the control panel and are not reconciled in this artifact.

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

It captures 4 rate-limit definitions, measuring concurrent_requests, concurrent_sessions, concurrent_connections, and bandwidth.

The profile also includes 3 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include Web Data, Web Scraping, Proxy, Rate Limiting, and Quotas.

Limits

Concurrent Requests (managed APIs) zone
concurrent_requests
see provider documentation
Web Unlocker / SERP / Web Scraper API concurrency ceiling per zone; scales with plan.
Concurrent Browser Sessions (Scraping Browser) account
concurrent_sessions
see provider documentation
Number of simultaneous CDP browser sessions; scales with plan and can be raised.
Proxy Concurrency zone
concurrent_connections
see provider documentation
Simultaneous open proxy connections per zone.
Bandwidth account
bandwidth
plan-dependent
Proxy and Scraping Browser usage is bandwidth-metered (per GB) rather than request-capped.

Policies

Per-Zone Configuration
Limits are set per zone in the control panel; different products/zones have independent ceilings.
Tiered Limits
Concurrency ceilings increase with higher plans and can be raised via support / enterprise agreements.
Backoff Strategy
Clients should implement retries with exponential backoff and honor 429 responses.
