| Type | Claude desktop-control capability (Anthropic API) | OSS browser-automation framework (Browserbase OSS) |
| Created | 2024-10 | 2024 (Browserbase release) |
| Latest release | computer_toolset_20260801 (2026-08) — current tool version, no beta header required | v3.7.3 (2026-08-28) — @browserbasehq/stagehand |
| License | proprietary (Claude API feature) | MIT |
| Pricing | Standard Claude API token pricing; ~4.5k input-token toolset overhead plus screenshots billed as image input; no per-action fee | 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) |
| Backend storage | stateless API | Local Playwright state; Browserbase-managed when cloud-hosted |
| Deployment | Managed-only — Claude API tool (also Bedrock, Vertex, Foundry); actions execute in a caller-provided desktop environment | Both (self-hosted + managed cloud) — library runs locally; Browserbase cloud browsers optional |
| API surface | Anthropic Messages API with computer-use tool | TS API (act/extract/observe); npm: @browserbasehq/stagehand |
| Multi-tenancy | API tenant | Per-process in OSS; per-tenant in Browserbase Cloud |
| MCP | no — computer use is a client-executed API tool, not an MCP server or client | yes — hosted Browserbase MCP server exposes navigate/act/observe/extract to any MCP client |
| Optimised for | Claude controlling a computer screen | Playwright-replacement with AI verbs (act / extract / observe) |
| Anti-fit | stateless capability — caller manages memory + safety | TS-only; not a finished agent — caller wires logic; tied closely to Browserbase ecosystem |

Pros & cons
Anthropic Computer Use
Pros: First and most-discussed computer-control LLM; substrate for many higher-level agentic apps; benchmark numbers are public.
Cons: Stateless — every implementer rebuilds the memory + safety layer; per-action API cost is unpredictable.
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).
