  • They diverge on capability: Flux covers Git as source of truth, Zeabur covers AI Agent.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Flux

  • No user interface of its own: observing what Flux is doing means CLI or a third-party dashboard
  • Debugging a stuck reconciliation is harder than reading a pipeline log, because failure is asynchronous
  • Everything must be in Git, which is awkward for secrets and needs a sealed-secrets or external-secrets approach
  • GitOps is a workflow change, not just a tool, and teams used to imperative deploys find the adjustment real

Zeabur

  • Free plan limited to single server with 48-hour log retention
  • Small team size may limit support and feature velocity
  • Building spec upgrades limited on lower tiers
  • Enterprise support not clearly documented
