Our take— Lindy wins
Based on our comparison of published pricing, features, and compliance data, Lindy scores 7.9/10 to Sudowrite's 7.1/10. Lindy pulls ahead with GDPR compliance and SOC 2 certification. Sudowrite stays close but doesn't lead on any single attribute here. Lindy is the call when GDPR compliance matters — otherwise Sudowrite.
