Can FullStory capture AI agent sessions on my store?

Generally no. FullStory's session capture is built around human interaction signals and its session-quality filters drop most agent sessions before they reach the dashboard. Even when an agent does trigger the capture script, the resulting "session" lacks the cursor movement, scroll inertia, and natural form interaction the analytics surface assumes — it reads as noise.

Should I replace FullStory with Serge?

No. The tools answer different questions about different traffic. FullStory measures human session experience; Serge measures AI agent task completion. Enterprise teams that adopt Serge usually keep their FullStory deployment for the human-session layer.

How does Serge's replay differ from FullStory's session replay?

FullStory replays a human session pixel-by-pixel — you see what the user saw and did. Serge captures an AI agent's journey as structured data: which DOM elements were targeted, which selectors matched, where the action chain broke, what the failure mode was. Same word ("replay") for two structurally different artifacts.

Does FullStory have any AI agent traffic detection?

Not as a published product feature. FullStory has anomaly detection over human-session metrics, but it does not run AI agents against customer stores or test whether one can complete a buying task. The "AI" in FullStory's materials refers to analytical AI over recorded human sessions, not agents under test.

Compare · FullStory vs Serge

FullStory captures every human session. Serge captures every agent test.

FullStory captures human sessions broadly — full DOM replay, event timeline, network log. Serge runs real AI agents — Claude, ChatGPT, Operator, Perplexity, Gemini — on your live storefront and captures every test result. Different traffic types, complementary tools.

Short version: FullStory's differentiator is broad session capture for human sessions — full DOM, event timeline, network log. It does this well within its scope. The scope ends at the bot-traffic filter, which generally drops AI agent sessions. Serge fills that gap.

Side by side

What each tool captures

Dimension	FullStory	Serge
What it captures	Every human session — full DOM replay, click + scroll + form events, network requests, console errors.	AI agent journey tests — real Claude/ChatGPT/Operator/Perplexity/Gemini against your storefront with structural failure analysis.
AI agent sessions	Generally treated as bot traffic by session-quality filters and dropped before the dashboard.	Every test is an agent. Fix snippet per failure.
Per-failure fix	"Frustration signals" surface where users struggle, but the engineering fix is on the customer team.	Paste-ready code snippet per failure — schema.org, ARIA, DOM semantics, robots.txt, cart state.
Reporting cadence	Real-time + scheduled. Anomaly detection on session-volume metrics.	Daily journey tests on Pro. Regression alerts. 12-month test history.
Pricing	Free tier plus paid tiers via contact-sales — see fullstory.com/pricing.	Free deterministic scan. Pro CHF 159/mo self-serve.

FullStory publishes a free tier but not full pricing for paid plans — contact the vendor for current rates.

How they fit

Where FullStory and Serge fit together

FullStory covers human sessions at scale. The capture model means you can answer many human-behaviour questions retrospectively — conversion drop-offs, frustration signals, behavioural cohorts.

Serge handles the layer FullStory doesn't reach — AI agent sessions, captured as structured task-completion data with a fix per failure. Two different traffic types, two different tools.

Enterprise teams that run both already have a FullStory implementation in place — Serge layers on top. The two answer different questions; teams that need both run both.
