## Browserbase strengths

- Free tier with 3 concurrent browsers and a low-cost $20/month Developer plan with 100 browser hours.

## Browserbase limitations

- 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 strengths

- 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

## System One API limitations

- 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
