ComfyUI-Autograph drives workflows from Python with REPL that knows your graph
Jumpy-Measurement-65 · reddit · 2026-08-23
ComfyUI-Autograph is a Python tool that allows developers to manipulate ComfyUI workflows directly via code, eliminating the need for a running GUI or HTTP server. It converts workflow. into an API payload and supports modifying node parameters using dot syntax (e.g., api.KSampler.seed = 42). The tool features a REPL environment that reads system node info (including custom nodes), providing Tab completion, option inspection (.choices()), and help text (.tooltip()). It also supports building graphs from scratch using >> for node connections, offline batch conversion, extracting workflows from ComfyUI PNG metadata, and serverless in-process execution. Currently used in production pipelines at a major VFX studio, it is compatible with ComfyUI versions 0.8.2 through 0.33.0.
