Pros & Cons

Langfuse

  • Genuinely free and unlimited self-hosting option under an open MIT license
  • Hobby tier’s 50k units/month is a generous free allocation for smaller projects
  • Backed by ClickHouse following its January 2026 acquisition and $400M Series D
  • Paid Cloud tiers scale meaningfully (Core $29 to Enterprise $2,499/month) based on usage volume
  • Overage billing ($8 per 100k units) requires monitoring usage to avoid unexpected costs
  • Recent acquisition by ClickHouse introduces some uncertainty around long-term product direction

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
