Introduction

Cloud

Use Browser Fleet's vendor accounts for every part by configuring none. Cloud costs $0.10 per job request; model token costs are billed separately.

What Cloud Includes

Browser Fleet uses these vendors for parts without your own keys. A Cloud job costs $0.10 per request and can run for up to two hours. Model token costs are billed separately, and proxy throughput is shared.

browsers

BrowserAct, through its CLI on the job's machine.

cloud_infrastructure

Cursor, which hosts the agent for each job.

llm

OpenCode Go with DeepSeek V4.1 Flash, the LLM of the agent that reads your steps and drives the browser.

stealth

CapSolver, 2Captcha, and NopeCHA.

network

Proxiware rotating residential proxies.

storage

Cloudflare R2. Each job's files are kept for seven days.

Switch Between Cloud and BYOK

An organization uses Cloud when its configuration leaves out at least one part. Changes apply to jobs that start after the update.

To BYOK

Send PUT /configuration with your vendor for every part except storage. Jobs are then billed at $0.02 per request.

To Cloud

Send PUT /configuration with an empty object.

Some parts

A configuration with some parts but not all runs no job. Set every part for BYOK, or none for Cloud.
