# Browser Use developer index

Browser Use offers two commercial products:

| Product | Use it when | Start here |
|---|---|---|
| Browser Use Agents | You want to submit a task and receive completed work | [Agents quickstart](https://docs.browser-use.com/cloud/agent/quickstart) |
| Browser Infrastructure | You want to connect your own code or agent to managed browsers | [Browser quickstart](https://docs.browser-use.com/cloud/browser/quickstart) |

Open Source, Browser Harness, the SDK, and MCP are developer tools and interfaces around these products—not additional commercial product families.

## Browser Use Agents

Give Browser Use a natural-language task and receive completed work from a managed browser agent. API V4 is the current interface for new integrations.

- Structured output with JSON Schema.
- Sessions and follow-up turns in the same browser context.
- Workspaces for persistent input and output files.
- Deterministic scripts that replay learned workflows without LLM cost.
- Human takeover for authentication and approvals.
- Progress events, recordings, webhooks, and observability.
- Hosted models or bring your own model key on eligible plans.

The default hosted model is GPT-5.6 Luna at $0.24/1M input tokens, $0.024/1M cached input tokens, and $1.44/1M output tokens. Browser time starts at $0.02/hour. See current model, network, and plan rates in [pricing.md](https://browser-use.com/pricing.md).

- $0.02/browser-hour, metered by the minute.
- Stealth browser builds and CAPTCHA handling.
- Residential proxies in 195+ countries or bring your own proxy.
- Persistent profiles for cookies, local storage, and authenticated sessions.
- Live preview, embeddable browser view, and session recordings.
