Skip to main contentRunComfy’s workflow versioning lets you iterate on ComfyUI workflows, including those modified from community templates, with built-in safeguards for reproducibility and stability. This allows you to focus on enhancing your workflow’s generative features without worrying about regressions or breaking deployments.
Save a New Version
To create a new version, launch an existing workflow into a ComfyUI session and make your updates. Then click Cloud Save in the top bar, keeping the same workflow name. RunComfy will automatically increment the version number and package the updated graph along with its complete runtime environment (drivers, libraries, custom nodes, models, and dependencies) into a new container image.
Version Limits and Auto‑Cleanup
Each workflow keeps up to 3 saved versions. When you save a new version, the oldest non‑deployed version is removed automatically to stay within the limit. Versions that are in use by a Serverless deployment are protected and will not be auto‑removed.
View and Launch Versions
Go to My Workflows, open the three‑dot menu, and select More Versions to see history. Launch any version into a ComfyUI session for review, edits, or deployment prep.
Deployments and Versions
Deployments are pinned to a specific workflow version. Creating new versions does not change running endpoints, they keep using the original version for uninterrupted operation.
Test updates in isolation, then switch the deployment to the new version in settings (see Edit a Deployment). Changes roll out with minimal downtime, similar to a rolling deployment, without disrupting live API traffic.
