Where Sparkle differs from Big Picture
Section titled “Where Sparkle differs from Big Picture”- Framework-level; does not provide enterprise policy or tenant governance
- Licensing and regulated mirror distribution are out of scope
- No multi-tenant policy plane
- No vendor-controlled mirror story
- No license server / leases
- No enterprise “MANAGED_BY_IT” mode unless built separately
How Big Picture differs
Section titled “How Big Picture differs”- Big Picture provides an enterprise control plane for release governance across products/tenants
- Big Picture offers explicit tenant policy + action decisions (AUTO_INSTALL, NOTIFY, MANAGED_BY_IT)
- Big Picture combines release governance + update policy + licensing in one coherent control plane
- Big Picture is designed around regulated downstream customers who require self-hosted artifact mirrors with signed metadata
Complementary integration
Section titled “Complementary integration”- Big Picture’s snapshot/decision system can point macOS clients at Sparkle feeds or Sparkle-compatible metadata (if configured)
- Big Picture can govern Sparkle-based updates with enterprise policy and staging controls
Suggested positioning
Section titled “Suggested positioning”“Frameworks provide the local updater mechanism; Big Picture provides the enterprise governance layer that makes self-update acceptable to IT and safe at scale.”
