Why teams look for a Clerk alternative

Before comparing options, it helps to name why teams leave Clerk in the first place:

  • Costs can grow as applications reach higher numbers of active users, which may impact rapidly growing platforms.
  • Applications rely on Clerk's infrastructure for authentication, which may concern teams that prefer full control over their user identity systems.
  • Compared with enterprise identity platforms, Clerk may offer fewer advanced identity management features and customization options for large organizations.
