| Type | Consumer browser-agent extension (Chrome) — Anthropic | OSS browser-automation framework (Browserbase OSS) |
| Created | 2025-08 | 2024 (Browserbase release) |
| Pricing | Not on Free; included in Pro ($20/mo, $17 annual), Max (from $100/mo), Team and Enterprise | OSS free; Browserbase Cloud handles runtime |
| Funding | Anthropic (parent) — $65B Series H at $965B post-money (2026-05-28); S-1 filed for a proposed IPO (2026-10-26) | Maintained by Browserbase ($40M Series B Q4 2024; Kleiner Perkins) |

| Multi-tenancy | Single-tenant per Claude account | Per-process in OSS; per-tenant in Browserbase Cloud |
| MCP | Claude supports MCP servers (caller-side) | yes — hosted Browserbase MCP server exposes navigate/act/observe/extract to any MCP client |
| Optimised for | Letting Claude act inside the user's logged-in Chrome rather than a fresh sandbox | Playwright-replacement with AI verbs (act / extract / observe) |
| Anti-fit | Claude Max preview only; Chrome only; prompt-injection risk model still maturing | TS-only; not a finished agent — caller wires logic; tied closely to Browserbase ecosystem |

Pros & cons
Claude for Chrome
Pros: First-party Anthropic agent inside the user's real browser; safety paper shipped at launch.
Cons: Claude Max preview only; Chrome-only; runs inside user's logged-in sessions (privacy surface).
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).
