LogRocket
- There is no free tier, only a 14 day trial; the Core plan starts at $176 a month for roughly 25,000 sessions
- Pricing scales with sessions captured, so cost tracks traffic rather than seats
- Galileo AI features are withheld from the Core plan and need Pro
- API and MCP access is limited on Core, with 500 credits a month on Pro and 2,000 on Enterprise
- Unlimited seats and streaming data export are Enterprise only
