ego lite vs Stagehand

La mejor alternativa a Stagehand

Stagehand is Browserbase's open-source SDK: you write TypeScript or Python, and methods like act, extract, and observe turn plain-language instructions into browser actions.

ego lite is a Stagehand alternative that skips the SDK entirely. Run /ego-browser and your coding agent controls ego lite directly, batching a whole task into one JavaScript call, finishing whole tasks 3 to 4x faster than Stagehand.

Por qué ego lite es mejor que Stagehand

Stagehand means maintaining a TypeScript or Python project, and every uncached action is another model call at runtime. With ego lite you type one sentence in Claude Code, Codex, or Cursor after /ego-browser. No project, no schema, no API key.

De 3 a 4 veces más rápido en tareas reales

In Stagehand, three clicks in a row can mean three separate trips to the model before the page moves again. Stagehand's own speed guide shows this pattern and suggests calling observe first so later clicks can reuse what it found.

Run /ego-browser and your coding agent controls ego lite directly. Every page arrives as a Snapshot: a compressed accessibility tree with stable @N refs it can act on instantly. Your coding agent spends its time on the task, not restructuring scripts, finishing whole tasks 3 to 4x faster than Stagehand.

Multitarea en paralelo, ejecución más rápida

Running several Stagehand tasks at once means spinning up and tearing down browser instances in your own code, or moving to Browserbase and hitting session caps of 3, 25, or 100. To see what happened, you open a replay after the run finishes.

In ego lite there's no cap on how many Spaces you open inside the same browser: each one runs its own task at the same time, controlled by a coding agent via /ego-browser on its own imported Chrome profile. None of them ever steals the tab you're using, and you can watch or take over any Space anytime.

Se acabó el ida y vuelta Menos costo en tokens

Stagehand's action cache helps when you repeat the same flow on the same page. On a new site, or after the DOM shifts, each call asks the model again, and stale caches have to be cleared by hand.

Run /ego-browser and your coding agent batches several actions in a few lines of JavaScript per turn to control ego lite. Stacked with Snapshot input, the same task completes on far fewer tokens overall.

El mismo Chrome, nativo para agentes

Staying logged in is the hard part of local Stagehand. Chrome profile support still has an open bug in v3, cookie workarounds often miss the HttpOnly session cookies that matter, and the browse CLI only attaches if you started Chrome with remote debugging yourself.

Built on Chromium, ego lite imports your entire Chrome setup in one click. When your coding agent runs /ego-browser, it controls ego lite with your real sessions already in place, so it doesn't stall on SSO, 2FA, or captchas on accounts you already have.

Hacé de esto una transición sin fricciones

Already running Stagehand scripts in CI or on a schedule? Keep those. Move one-off and logged-in exploratory work to ego lite in a few minutes.

  1. Descargar ego (lite)

    Descarga ego lite e importa tu perfil de Chrome con un clic. Los inicios de sesión, las cookies y las extensiones se importan junto con él.

  2. Ejecuta tu primera tarea con /ego-browser

    Pega esto en tu agente

    /ego-browser Abrí ego.app y sumate a la lista de espera

    Paste one sentence into Claude Code, Codex, or Cursor and hit enter. No SDK, no model API key, no Zod schema.

  3. Míralo en acción
    Vista general de Spaces en ego lite con cuatro tareas de navegador corriendo en paralelo: Claude Code siguiendo la acción de Apple en Yahoo Finance, Codex filtrando autos por año en cars.com, Hermes terminando una tarea de back-office de SaaS, un usuario haciendo scraping en X, y una mano tocando + para abrir otro Space

    The task runs in its own Space, so your tabs stay untouched. Watch live or take over anytime. Results land back in your agent's CLI.

Keep Stagehand for committed automation, typed extraction, and deterministic locators.

Cuándo usar cada herramienta

Elegí ego (lite) cuando

  • You'd rather describe a one-off scrape or form fill than maintain a TypeScript or Python project for it.
  • The work sits behind your own logins and should start signed in.
  • You want parallel Spaces you can watch, without managing browser instances in code.
  • You don't want to add an SDK, model key, and project for something your coding agent can already do.

Elegí Stagehand cuando

  • Automation must live in a repo with review, caching, and the same run months later.
  • You want a deterministic escape hatch: precise locators when a flow must not vary.
  • You need typed extraction with a Zod schema into TypeScript.
  • It must run in CI or across many cloud browsers on Browserbase.

Preguntas frecuentes

Stagehand is Browserbase's MIT-licensed browser automation SDK for TypeScript and Python. It gives you act, extract, observe, and agent primitives, plus precise locators when you want to skip the model. It runs locally against Chromium, and pairs with Browserbase when you want hosted sessions, caching, and replay. For automation you commit to a repo and run on a schedule, it remains an excellent choice.

For interactive, logged-in browser work, yes: run /ego-browser and describe the task. For committed automation you ship to CI, with typed extraction and deterministic locators, keep Stagehand. Stagehand is for browser work you commit; ego lite is for browser work you do today.

No. Stagehand runs locally against Chromium on its own. Browserbase is optional when you want hosted sessions, server-side caching, and replay. The Browserbase vs Stagehand pairing matters for cloud fleets, not for a local script on your laptop. ego lite has no hosted path: local only, free, no account.

Often yes in production, but for different reasons. Stagehand is the SDK you write act, extract, and observe calls in. Browserbase is where those scripts run when you need cloud scale. For your own agent chores on logged-in sites, you may need neither: run /ego-browser and let Claude Code or Codex drive ego lite directly.

Stagehand is MIT-licensed and free to install. You pay model tokens for every act, extract, or observe call that is not cached, plus Browserbase browser minutes if you host it there. ego lite is free. You only pay the model tokens your coding agent already uses.

Not dependably in local mode today. Pointing Stagehand at your Chrome profile still has an open bug in v3, and cookie workarounds often miss the HttpOnly session cookies that matter. ego lite imports your Chrome profile once, and every task starts signed in.

They aim at different developers. Stagehand is TypeScript-first with act, extract, and observe primitives for hybrid code-plus-AI automation. Browser Use is Python-first and runs a more autonomous agent loop. Both are frameworks you write and fund. ego lite is the Chromium browser your coding agent controls via /ego-browser. See ego lite vs Browser Use for that side.

Stagehand is an SDK: you write act, extract, and observe calls in TypeScript or Python. agent-browser is a CLI your agent shells out to, one command at a time. ego lite is neither. Run /ego-browser and your coding agent controls ego lite with batched JavaScript. See ego lite vs agent-browser.

Not as a native skill. Claude Code would run a Stagehand script you wrote, with model API keys and a project to maintain. ego lite is the shorter path: run /ego-browser in Claude Code, Codex, or Cursor and describe the task. No SDK install, no schema, no separate model billing loop.

When an action is not cached, the model picks the target again each time, so a shifting page can resolve differently. Caches can also go stale after the DOM changes. Use Stagehand's precise locators when a flow must not vary. ego lite is built for interactive work where some variation is acceptable.

Neither. Run /ego-browser in Claude Code, Codex, Cursor, Gemini CLI, or OpenCode. Free on macOS 12+, no account required.
