Puppeteer - Pros & Cons
Pros
- ✓Supports both Chrome and Firefox automation through documented browser protocols: DevTools Protocol and WebDriver BiDi.
- ✓Runs headless by default, which fits CI pipelines, server-side jobs, and automated testing environments without a visible browser UI.
- ✓The standard puppeteer package downloads a compatible Chrome during installation, reducing setup friction for developers who want a working browser binary immediately.
- ✓puppeteer-core is available for teams that want the API without downloading Chrome, which is useful in Docker images or environments with centrally managed browser versions.
- ✓Works with npm, Yarn, pnpm, and Bun according to the installation docs, so it fits most modern JavaScript package-management workflows.
- ✓Includes documented support for chrome-devtools-mcp and experimental WebMCP, making it relevant for browser automation and debugging workflows connected to AI tooling.
Cons
- ✗It is a code-first JavaScript library, so non-developers will likely need engineering support to build and maintain automations.
- ✗Browser automation is heavier than HTTP scraping because each job may require launching or connecting to a real browser instance.
- ✗Reliable use requires careful handling of navigation, selectors, asynchronous page behavior, and browser lifecycle events.
- ✗The website does not present hosted scheduling, proxy management, captcha handling, or managed scraping infrastructure as built-in product features.
- ✗WebMCP support is described as experimental, so teams should treat it cautiously for production-critical automation.
Steel - Pros & Cons
Pros
- ✓Truly open source under MIT — no SaaS lock-in
- ✓Playwright/Puppeteer compatibility means existing scripts port over
- ✓Stealth and proxy rotation are handled — no anti-bot whack-a-mole
- ✓Self-host or cloud — same binary, you pick the deploy model
- ✓Strong fit for regulated environments where data can't leave the VPC
Cons
- ✗Cloud pricing not transparently published — verify before depending on it
- ✗Stealth tactics are a moving target as anti-bot vendors evolve
- ✗You still write the agent loop on top — Steel doesn't decide what to click
- ✗Smaller ecosystem of pre-built integrations than Browserbase
