Design doesn't follow software development best practices

7/10 High

LangChain's architecture leads to messy, non-modular code that's difficult to scale or maintain as projects grow. The framework lacks features like automatic prompt versioning and joint prompt evaluation, making reproducibility and maintenance harder in production.

Query: “What are the most common pain points with LangChain for developers in 2025?”3/30/2026

Its design doesn't generally follow software developer best practices. Code gets messy fast, things aren't modular, and it's tough to scale or maintain as your project grows... it doesn't automatically version both your prompt and the code around it, which makes reproducibility harder.
