StewAI

StewAI lets you build AI workflows that run in steps without writing code. You tell each step what to do, define how the answer should come back, and pass results from one step to the next. Every run shows what each step costs in credits, so you always know the workflow cost before scaling it. When a workflow works, you can publish it to the marketplace for others to run or use as a step in a bigger one. Prefer code? There's a Python SDK. The free plan comes with 500 credits; paid plans start at $10 a month.
