zStorage offers no permanent free tier. According to G2's pricing data for zStorage, a free trial is available for evaluation before committing to a paid plan. G2 reviewers confirm the trial helps identify exact capacity and configuration needs before purchase. zStorage's paid plans operate on consumption-based, hourly pricing with custom enterprise quotes — no fixed published tiers.
