Evaluate Payload CMS alternatives against your actual collections, relationships, blocks, localization, drafts, versions, media, hooks, jobs, and access-control rules. Prototype the most complex schema and an editorial workflow, then test generated APIs, authentication, validation, migrations, and query performance. Compare self-hosting, managed deployment, database support, upgrade policy, observability, and security ownership. Export representative content and media to measure migration fidelity. Do not switch until rollback, URL preservation, and webhook or integration replacements are documented.
