how to choose a FullStory alternative
Easiest to get running
Umami — a one-click install, no server to maintain.
Most proven
PostHog, with 37,500 GitHub stars — the largest community of the 5, which usually means more answers when something breaks.
Works on your phone
PostHog has a mobile app on iOS and Android.
Needs real ops to self-host
OpenReplay is capable but expects someone to run a server, updates and backups. Budget for that before choosing it.
what you give up by leaving FullStory
- high-fidelity replay, privacy redaction, indexing, search, storage, and compliance
- identity stitching
- session replay
- warehouse connectors
- high-volume global ingestion and support
None of the picks above covers all of it. The full verdict says which gaps matter.

why people still pay for FullStory
People still pay for FullStory because teams pay because analytics must keep collecting and remain trustworthy while the product changes underneath it. The recurring cost buys event schemas, bot filtering, identity, late data, retention, query cost, privacy, backups, and always-on ingestion, not just the visible interface.
