Why we included this project
ChainForge gives you a visual data-flow canvas for testing prompts against several models at once, instead of pasting variations into one chat window at a time. You wire up prompt templates, send them to a batch of LLMs or to the same model under different settings, then attach scoring functions, either hand-written Python or LLM-generated starter code, and see results plotted across prompt permutations and settings. That makes it a practical tool for choosing prompt variants and model configurations before locking something in. It is not a hosted evaluation platform, so you bring your own API keys and, for serious work, run it locally. Researchers and small teams that want a low-code way to run prompt experiments will find it a useful alternative to writing comparison scripts by hand.
