How pricing works

Billed with

Feature Flags

Experiments are bundled with Feature Flags and share volume limits, so you get access to both products for the same price.

  • 1 million requests free every month
  • Usage billed as Feature Flags requests after the free tier
  • Experiments at no additional cost

Same request meter as Feature Flags – no separate Experiments SKU.

TL;DR:

PostHog vs...

An honest comparison, tl;dr:

Choose a competitor if...

  • No-code experiments or CMS capabilitiesYou'll still need a designer/engineer to create experiments – but we're working on no-code A/B testing!
  • No integration with Google AdsPostHog can't run ad experiments, or target users into an experiment based on an ad variant engagement.
  • PersonalizationOf course, you could set up personalization yourself, but we don't have pre-built components or templates for this.

Go with if...

  • Agents can read experiment results and act on them – the evaluation that powers self-drivingResults are part of one platform, so an agent can check whether a change actually worked and ship the winner.
  • Integration with other PostHog productsAttach surveys to experiments or view replays for a test group. Analyze results beyond your initial hypothesis or goal metric.
  • Group-level experiments for B2BTest features at the organization level to avoid contamination between users in the same company
  • Shared metrics libraryCreate consistent, reusable metrics across all experiments

It's free to start. Not "free trial" free – actually free. No card, no call, no "someone from our team will be in touch." Just PostHog.

No sales call. No "tailored demo." No expiry.
