[simple-agent-manager]

Context

Part of the Pricing V5 implementation. Source: strategy/pricing-implementation-checklist.md §8.

Tasks

Tier Name Updates

• Playground docs (docs/concepts/defang-playground.md): Rename "Hobby"→"Starter", update resource limits
• Onboarding/getting started: Update any "Hobby" or "Personal" references

Mode & Tier Requirements

• Deployment Modes (docs/concepts/deployment-modes.md): Add tier requirements:
  • AFFORDABLE: "Available on all Navigator tiers"
  • BALANCED: "Requires Pro ($49/mo) or Enterprise"
  • HA: "Requires Enterprise ($499/mo)"
• Scaling (docs/concepts/scaling.md:38-40): Update "Pro plan or higher" pricing reference
• BYOC (docs/concepts/defang-byoc.md): Add pricing context for cloud accounts

AI Feature Docs

• Generate (docs/concepts/generate.md): Note Starter has limited AI, Pro unlocks full access
• Debug (docs/concepts/debug.md): Add "Requires Pro subscription" note

Managed Services Docs

• Managed Storage (docs/concepts/managed-storage/managed-storage.md): Confirm available on all Navigator tiers (not just Pro+)
• Managed LLMs (docs/concepts/managed-llms/managed-language-models.md): Same confirmation
• Note: Playground still does NOT support managed services — unchanged

New Pricing Page

• Create standalone pricing docs page (docs/concepts/pricing.md or docs/concepts/plans.md):
  • Tier comparison table
  • Cloud account pricing
  • Upgrade/downgrade instructions

Blog Content

• Search for "$10", "$30", "Personal plan", "Hobby" in blog content and update if needed

Decisions resolved (source)

• Mode naming: Keep current — Affordable / Balanced / High Availability
• FOSS Community: Do not reference in pricing. Source is available but not a separate tier or community edition. Remove any FOSS Community references from pricing docs.
• SDUs: Do not exist anymore — remove any SDU references in docs
