| Use cases | Scoped Agentic | Scoped Agentic, Code Generation Focused |
| Type | Consumer computer-use agent (browser-only) | OSS browser-automation framework (Browserbase OSS) |
| Created | 2025-01 | 2024 (Browserbase release) |
| Pricing | Bundled with ChatGPT Pro $200/mo | OSS free; Browserbase Cloud handles runtime |
| Funding | OpenAI parent — ~$157B val 2024-10; $40B round Mar-2025 ($300B val) | Maintained by Browserbase ($40M Series B Q4 2024; Kleiner Perkins) |
| Backend storage | OpenAI-hosted browser session state; no durable cross-session memory by default | Local Playwright state; Browserbase-managed when cloud-hosted |
| Deployment | Cloud (OpenAI-hosted browser sandbox) — no self-host | Both (self-hosted + managed cloud) — library runs locally; Browserbase cloud browsers optional |
| API surface | Computer tool (type computer) in the Responses API; current docs use gpt-6.1-sol, with a migration guide from computer-use-preview | TS API (act/extract/observe); npm: @browserbasehq/stagehand |
| Multi-tenancy | single-tenant per ChatGPT Pro account; sandboxed sessions | Per-process in OSS; per-tenant in Browserbase Cloud |
| MCP | searched not found | yes — hosted Browserbase MCP server exposes navigate/act/observe/extract to any MCP client |
| Optimised for | Consumer-grade autonomous web tasks in OpenAI-hosted browser | Playwright-replacement with AI verbs (act / extract / observe) |
| Anti-fit | Not for desktop apps (browser-only); no self-host; US-only at launch | TS-only; not a finished agent — caller wires logic; tied closely to Browserbase ecosystem |

Pros & cons
OpenAI Operator
Pros: First consumer-grade computer-use agent from a major lab; OpenAI distribution; benchmark numbers public.
Cons: US Pro-only at launch; browser-only; OpenAI-hosted (no self-host); takeover UX still rough.
Stagehand
Pros: Browserbase-backed OSS; clean act/extract/observe primitive; growing TS-agent ecosystem.
Cons: TS-only (no Python parity); ties best with Browserbase Cloud (vendor adjacency).
