Grain vs FullStory
FullStory is for enterprise teams who want the richest replay and will pay for it. Grain is for teams who want replay plus an AI analyst that turns it into an answer.
The richest session replay and autocapture available, with deep frustration signals and a mature enterprise platform. If replay fidelity is the whole game and budget isn't the constraint, it's excellent.
Replay plus Kai — an AI analyst that reviews the sessions and names the cause — with cookieless tracking, EU hosting, and transparent, published pricing instead of a quote.
They overlap on: Session replay, heatmaps, autocapture, funnels, custom dashboards, mobile analytics.

When FullStory is the better choice
- Replay fidelity and autocapture depth are the whole point for you.
- You're an enterprise comfortable with a sales-led motion and a quote.
- You need FullStory's mature frustration signals and rich session search.
- US data hosting and cookie-based tracking are fine for your compliance posture.
- You have the team to review sessions and draw the conclusions yourself.
When Grain is the better choice
- You want Kai to review the sessions and name the cause, not just record them.
- You need cookieless tracking that survives consent rejections.
- You need EU-hosted data, not US-centric processing.
- You want published, predictable pricing instead of an enterprise quote.
- You're on WordPress or WooCommerce and want native server-side tracking.
Run both, no commitment
FullStory and Grain coexist. Some teams keep FullStory for its deep replay search and add Grain for the AI analysis, cookieless tracking, and EU hosting FullStory doesn't offer. Email eray@grainql.com for a 90-day Growth-tier trial.
