⚠Scale tier pricing may be prohibitive for small teams, solo developers, or early-stage startups still validating their LLM use case
⚠Workflow editor complexity increases significantly for deeply nested or highly dynamic pipelines, where code-first approaches may offer more flexibility
⚠Ecosystem integrations are narrower than more established DevOps-adjacent platforms like LangSmith, which benefits from tight LangChain framework coupling
