Pros & Cons

Haystack

  • Genuinely free, open-source core framework under the permissive MIT license
  • Explicit control over retrieval, routing, memory, and generation for production applications
  • Commercial tiers add managed infrastructure and visual tooling without gating the core framework
  • No public pricing for Enterprise tiers — requires direct sales contact for a custom quote
  • Enterprise pricing scales by organization size without a transparent published rate card
  • Full production deployment at scale requires development expertise to configure pipelines effectively

Gemini

  • Deeply integrated across Google’s broader ecosystem (Search, Workspace, Android)
  • Ultra tier pricing was reduced from its original $250/month, improving accessibility
  • API pricing offers genuinely low-cost options (Flash-Lite at $0.10/million tokens) for cost-sensitive applications
  • Full Workspace integration requires at least Business Standard ($14/user/month), not available on cheaper Workspace tiers
  • Credit-based system layered on top of tier usage limits adds complexity to understanding real usage capacity
  • Ultra tier’s $99.99-$199.99/month range represents significant cost for maximum usage limits and Deep Think access
