It provides a standard framework to develop interoperable components and connect; pick AdalFlow if adalFlow is designed to streamline the development and automatic optimization of LLM applications. [langchain](https://docs.langchain.com/langchain/) reports 142k GitHub stars, 24k forks, and 419 open issues, last pushed Jul 11, 2026. [AdalFlow](http://adalflow.sylph.ai/) has 4.2k stars, 378 forks, and 65 open issues, last pushed May 29, 2026.
