It is configurable via YAML and can be integrated into CI pipelines for automated testing; pick ChainForge if web-based visual programming tool for prompt testing on LLMs; supports local installation and Docker for advanced feature access. [contextcheck](https://addepto.com/) reports 97 GitHub stars, 11 forks, and 1 open issues, last pushed Dec 11, 2024. [ChainForge](https://chainforge.ai/docs) has 3.0k stars, 257 forks, and 70 open issues, last pushed Sep 19, 2026.
