- The AI gateway fails over automatically across five providers (Anthropic, Google, OpenAI, DeepSeek and xAI)
❌ Cons
- The pricing page offers no free plan or trial; each tier leads to a booked demo
- Starter is capped at 10 users and one AI teammate and Growth at 50 users, so larger teams need a custom Enterprise quote
