The short version

  • Only GrowthBook has a free tier, so it costs nothing to try first.
  • Each has a real cost: BrowserStack volume pricing for 25+ users and custom pricing for higher parallel counts not publicly listed; GrowthBook warehouse-native analysis is only an advantage if you have a warehouse with clean event data in it; without one, GrowthBook has nothing to compute against and you are back to buying an event-collecting platform.

What people use each for

  • Validating payment workflows on real devicesnot GrowthBook
  • Testing web performance on real devicesnot GrowthBook
  • Testing localization from 100+ countriesnot GrowthBook

GrowthBook

  • An engineering team that wants feature flags without a per-monthly-active-user bill that grows with product successnot BrowserStack
  • A data team that needs experiment results to reconcile exactly with the metrics reported in its BI toolnot BrowserStack
  • A company with data residency or privacy constraints that cannot send user-level event data to a third-party vendornot BrowserStack
  • Running long-tail experiments where sequential testing and CUPED shorten the time to a decision on low-traffic surfacesnot BrowserStack

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

BrowserStack

  • Volume pricing for 25+ users and custom pricing for higher parallel counts not publicly listed
  • Annual billing saves up to 25% versus monthly, but specific annual prices not published for all tiers

GrowthBook

  • Warehouse-native analysis is only an advantage if you have a warehouse with clean event data in it; without one, GrowthBook has nothing to compute against and you are back to buying an event-collecting platform.
  • Metrics are SQL, so a marketing or product team without data engineering support cannot define or fix them, and a badly written metric silently produces a confident wrong answer.
  • Cloud Pro bills per seat and then adds CDN request and bandwidth overages, so a high-traffic site can find the variable component exceeds the seat cost it budgeted for.
  • Self-hosting means you own the Mongo database, the SDK endpoint availability and the upgrade path, and a flag service that is down is a production incident, not an analytics inconvenience.
  • The statistics engine exposes real choices, Bayesian versus frequentist, sequential testing, variance reduction, and the tool will not stop a team that configures them wrongly, so it rewards statistical literacy and punishes its absence.

Answered from the vendors’ own pages

BrowserStack: How much does BrowserStack cost?

BrowserStack Freelancer plan starts at $12.50/month (100 minutes, 1 user), Desktop plan costs $29/month, Desktop & Mobile plan costs $39/month (marked as best value), and Team plans start at $150/month for 5+ users. Annual billing saves up to 25% compared to monthly billing. All prices are for annual commitment.

Source
GrowthBook: Is the self-hosted version actually usable, or crippled?

It is genuinely usable: unlimited users, flags and experiments on one project under an MIT licence. The paid tiers add multiple projects, SSO, audit logs and support.

BrowserStack: What testing minute limits does BrowserStack provide?

Freelancer plan includes 100 testing minutes monthly. All other individual and team plans provide unlimited testing minutes. Team sizes start at 5+ users for team plans.

Source
GrowthBook: Do I need a data warehouse?

For experiment analysis, effectively yes. Feature flagging works without one, but the reason to choose GrowthBook over a flag-only tool is the warehouse-native statistics.

BrowserStack: How many devices can you test simultaneously on BrowserStack?

Individual plans allow standard device testing. Team Pro plans enable 4 simultaneous devices, Team Ultimate enables higher simultaneous testing. Automation Pro plans support multiple parallel tests, with volume discounts available for higher parallel counts (2, 5, 5+).

Source
GrowthBook: How does the cost compare with LaunchDarkly or Optimizely?

GrowthBook charges per seat rather than per monthly active user or per tracked event, so cost stops scaling with traffic. At high volume that difference is large.

BrowserStack: What automation testing plans does BrowserStack offer?

Automate Chrome plan costs $59/month for 1 parallel. Automate Desktop costs $99/month (1 parallel, 3000+ browsers). Automate Standard costs $175/month (1 parallel, desktop and mobile). Automate Pro costs $225/month and adds SIM card testing, real device performance testing, and AI agents for self-healing and failure analysis.

Source
GrowthBook: Does it support mobile and server-side flags?

Yes, there are SDKs across JavaScript, React, Python, Go, Ruby, PHP, Java, Kotlin, Swift and more, covering client, server and mobile evaluation.
