Gotchas - check before you buy

medium

Sync pricing unpublished; expect a sales conversation before you can budget

medium

Proprietary storage means full data migration if you ever leave

medium

No public security page; encryption relies on platform features and DIY key handling

Five-employee vendor: support depth and long-term roadmap are thin

Pros and cons

  • Case studies claim up to 60% cloud cost reduction
  • Now doubles as an edge vector database since v4.0

Cons

  • Encryption unclear; developers still open GitHub issues asking
  • Sync is a paid SaaS with unpublished pricing
  • Tiny vendor: 5 employees, ~$688K revenue; longevity risk
