About
CLI scaffolder for browser automation apps from Browserbase.
What it does
Create Browser App produces a ready-to-run TypeScript project for building Stagehand browser agents. You choose a project name and either the bundled starter or a named example fetched from GitHub. It creates the directory, updates project metadata and documentation, then prints setup steps for dependencies and credentials.
Why it's ranked here
It is a focused starting point with unusually useful starter behavior: structured extraction, action discovery, validated execution, and explicit resource cleanup. Dynamic examples broaden its reach without bloating the package. The narrow Browserbase and Stagehand commitment makes it less useful as a general browser automation starter.
What's good
The bundled project demonstrates the complete browser lifecycle, checks required credentials, validates extracted data with a schema, verifies observed actions before execution, and closes both Stagehand and the browser in nested cleanup blocks. Generated projects also include strict TypeScript settings and coding guidance for agents.
Tradeoffs
The generated starter requires a Browserbase API key, Node.js 22.18 or newer, pnpm, and the Stagehand ecosystem. Named templates depend on live GitHub access. Missing templates fall back to the basic starter, while partially downloaded templates can be layered over bundled files. Existing destination directories cause an immediate exit.
How to use it well
Use it when a TypeScript team wants a small, opinionated Stagehand proof of concept or a quick base for extraction and interaction workflows. Start with the bundled example to learn the lifecycle, then select a remote template for a closer use case. It does not provide a general automation framework, deployment system, or hosted agent runtime.
Technical notes+
src/cli.ts uses Commander, fs-extra, Chalk, and Boxen to sanitize the directory name, reject existing targets, copy template/, optionally overlay remote files, rewrite package metadata and the README heading, and print pnpm setup steps. src/templateFetcher.ts queries GitHub’s contents API, recursively walks directories with Promise.all, downloads file buffers in parallel, and returns empty results on HTTP, parsing, or network errors. template/index.ts launches Browserbase, creates Stagehand, exercises extract, observe, and act, checks result envelopes, and closes resources in nested finally blocks. package.json builds the ESM CLI with tsup and publishes dist, template, and examples.
