LangGraph vs Stagehand

A side-by-side look at pricing, capabilities, pros, cons, and our editorial scores.

	LangGraph Agents	Stagehand Agents
Tagline	Stateful, graph-based agent orchestration from LangChain.	The SDK for browser agents
Category	Agents	Agents
Pricing	Freemium· Developer: $0 / seat per month · Plus: $39 / seat per month · Enterprise: Custom pricing	Freemium· SDK is free/open-source (MIT). Runs locally against any LLM API key. Optional Browserbase cloud runtime: Free $0/mo, Developer $20/mo, Startup $99/mo, Scale custom.
Model	BYO (Claude / GPT / open)	Model-agnostic (OpenAI GPT-4o, Anthropic Claude, Google Gemini via Vercel AI SDK)

Pros	Reliable, debuggable agent graphs Built-in persistence + HITL Production-grade Tight LangSmith integration	Open-source (MIT) and built directly on Playwright, so you never lose escape-hatch access to the raw page, frame, and network APIs Natural-language act/extract/observe primitives eliminate most brittle selectors and dramatically reduce maintenance when target sites change Zod-schema extraction returns typed, validated data instead of loose JSON, which fits cleanly into typed backends Model-agnostic via the Vercel AI SDK — swap OpenAI, Anthropic, Gemini, or a self-hosted model without rewriting the agent Optional Browserbase cloud provides stealth browsers, residential proxies, session replay, and captcha handling out of the box TypeScript and Python SDKs with good docs, a growing example library, and an active Discord observe() lets you inspect proposed actions before executing, which makes debugging and human-in-the-loop review practical
Cons	Steeper learning curve than CrewAI Verbose to set up	Every act/extract call issues an LLM request, so token costs and latency add up fast on large crawls compared with hand-written Playwright Non-deterministic by nature — the same prompt can occasionally pick a different element, so critical flows still need assertions and retries Cloud features (stealth, proxies, captcha) require a paid Browserbase plan; running purely local means you handle those problems yourself Still a young project — API surface and best practices are evolving and breaking changes appear between minor versions Requires developer skills (Node/TS or Python) — no visual builder for non-technical automators
