• Retroactive event definition eliminates 'we didn't track that' entirely.
• Very fast time to first insight — no instrumentation project required.
• Warehouse sync for teams that want the raw data.

• No cost and no sampling at any volume — nothing else in the category comes close on price.
• Rage-click and dead-click detection surfaces real usability problems immediately.
• Easy to install and reasonable default masking of sensitive fields.

• Autocaptured data needs governance or the event list becomes unusable noise.
• Session-based pricing on high-traffic products.
• Acquisition means overlap with Contentsquare's own products.

• Data goes to Microsoft, which is a real consideration for GDPR-sensitive deployments.
• Filtering and segmentation are shallower than paid tools.
• Support is community-based and the roadmap is not yours to influence.

Product teams that want analytics without an instrumentation backlog.

Almost anyone starting with session replay, and anyone whose paid tool is mainly used for basic replay.
