How to actually pick one
Three-question filter:
- Can you self-host? If yes, the open-source picks usually win on cost and data ownership.
- Will the alternative cover ≥80% of your current use case? Don’t switch for a 50% feature match — the hidden cost of workflow re-learning outweighs the savings.
- What does the renewal math say? Calculate 12 months of cost on the alternative vs. FullStory, then subtract switching cost (estimated at ~1 work week).
