How to actually pick one

Three-question filter:

  1. Can you self-host? If yes, the open-source picks usually win on cost and data ownership.
  2. 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.
  3. What does the renewal math say? Calculate 12 months of cost on the alternative vs. Sentry, then subtract switching cost (estimated at ~1 work week).
