Stagehand

Stagehand is not a coding assistant; it is developer infrastructure for browser agents. It belongs in the first batch because modern AI software builders increasingly need reliable browser automation for QA, data collection, onboarding, and web workflows, and Stagehand explicitly combines natural-language instructions with deterministic Playwright-style code.

• Open-source MIT framework for browser agents, backed by Browserbase's hosted infrastructure.
• Lets developers mix natural-language actions with code-level browser automation when prompts alone are too brittle.
• Strong fit for AI testing, browser QA, data extraction, and agent workflow infrastructure pages.
• Where it fits: Browserbase's open-source browser automation framework for building browser agents that combine natural-language prompts with Playwright-style code.

• Agent building and orchestration: Stagehand applies this capability to Browser agents, Automation SDK workflows so users can move faster while keeping output quality reviewable.
• Model hosting, evaluation, and deployment: Stagehand applies this capability to Browser agents, Automation SDK workflows so users can move faster while keeping output quality reviewable.
• Workflow automation and integrations: Stagehand applies this capability to Browser agents, Automation SDK workflows so users can move faster while keeping output quality reviewable.
• Datasets, demos, and collaboration: Stagehand applies this capability to Browser agents, Automation SDK workflows so users can move faster while keeping output quality reviewable.
• Monitoring, APIs, and production operations: Stagehand applies this capability to Browser agents, Automation SDK workflows so users can move faster while keeping output quality reviewable.

• Install the open-source Stagehand SDK (MIT) into your Node or TypeScript project.
• Build a browser agent by mixing natural-language actions with Playwright-style code.
• Connect Browserbase hosted infrastructure (Free, then Developer at $20/month) for reliable browsers.
• Fall back to deterministic code where prompts alone are too brittle for a step.
• For production agents, handle identity, consent, data retention, target-site terms, and browser costs.

• Stagehand offers a free tier or trial, so you can evaluate it before upgrading.
• Paid plans for Stagehand start at about $20/mo, with higher tiers unlocking more usage, stronger models, and team features.
• Stagehand itself is open source under the MIT license. Browserbase infrastructure starts with a Free plan, then Developer at $20/month, Startup at $99/month, and custom Scale plans for browser-agent infrastructure.
• Separate the open-source SDK from Browserbase hosted browser infrastructure when explaining cost.
