Pros and cons

Browserbase

Pros

  • Free tier with 3 concurrent browsers and a low-cost $20/month Developer plan with 100 browser hours.
  • Works with Playwright, Puppeteer and Selenium, so existing scripts can move to cloud browsers.
  • Live view, logs and session replay help debug agent runs.
  • Bundles browsers, Search, Fetch, Functions and a Model Gateway in one platform.
  • Lists SOC 2 Type II infrastructure and HIPAA (BAA) on the Scale plan.

Cons

  • Costs scale with usage: browser hours, proxies, search and fetch calls are billed separately beyond plan allowances.
  • The Free plan has only 1 browser hour and 15-minute sessions, so it suits testing rather than real workloads.
  • Aimed at developers; there is no consumer app and no mobile app was found.
  • Advanced stealth, HIPAA and SSO are tied to the custom-priced Scale plan.

System One API

Pros

  • Pay-as-you-go credits with no subscription and no expiry
  • Failed calls are not charged
  • Public model catalogue with prices and limits
  • Structured outputs with per-option probabilities
  • Open-source MIT-licensed TypeScript SDK

Cons

  • Early-stage project: the SDK repository has very few GitHub stars and the company is not identified on the site
  • No published latency, uptime or accuracy guarantees
  • Limited to classification, scoring and yes/no style decisions rather than generation
  • Hosted models are the vendor's own and independent benchmarks are not provided
