Steel · Rate Limits

Steel Dev Rate Limits

Steel Cloud meters usage primarily by concurrent browser sessions and monthly browser hours rather than fixed requests-per-second limits, with bundled proxy bandwidth and CAPTCHA solve allotments per plan. Concurrency caps, monthly browser-hour allotments, proxy bandwidth, and CAPTCHA solves scale with the subscription tier (Hobby, Starter, Developers, Startups, Enterprise). Self-hosted steel-browser instances have no Steel-imposed limits beyond local hardware. Specific per-tier concurrency and request values are not reconciled in this artifact.

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

It captures 5 rate-limit definitions, measuring sessions, browser_hours, gigabytes, solves, and requests.

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 3 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include Browser, Web Automation, Scraping, AI Agents, and Open Source.

Policies

Tiered Limits
Concurrency and monthly allotments raise as accounts move from Hobby to paid and Enterprise tiers.
Self-Hosted Exemption
Self-hosted steel-browser instances are not subject to Steel Cloud limits; throughput is bounded only by local resources.
Backoff Strategy
Clients should implement exponential backoff with jitter on 429 responses and honor Retry-After where present.
