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.
• Keep in mind: Teams still need to handle identity, consent, data retention, target-site terms, and hosted browser costs for production agents.

• 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.

• Open the official website and create a project, workspace, or organization. Keep a human review step in the workflow for facts, privacy, rights, and brand fit.
• Choose a model, agent template, automation flow, or deployment target. Keep a human review step in the workflow for facts, privacy, rights, and brand fit.
• Connect data sources, tools, APIs, and permissions required by the workflow. Keep a human review step in the workflow for facts, privacy, rights, and brand fit.
• Test with realistic inputs, inspect logs, and refine prompts, tools, or policies. Keep a human review step in the workflow for facts, privacy, rights, and brand fit.
• Deploy, monitor, and iterate as usage patterns and reliability requirements evolve. Keep a human review step in the workflow for facts, privacy, rights, and brand fit.

• 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.
