Ino Increment Batch Name

Timestamps give you uniqueness but not order - 20260816_143522 is useless for "give me the fifth run." When you want outputs numbered 1, 2, 3, ... across runs, Ino Increment Batch Name is the tool: feed it Batch_00001 and it returns Batch_00002; run it again and you get Batch_00003. The description spells it out: "Increments a batch name string (e.g. Batch_00001 -> Batch_00002)."

The trick - and it's the part people miss - is that it's stateful across executions. ComfyUI doesn't keep variables between runs by default, but this node does, which is exactly what makes a persistent counter possible.

How it works

You give it a name (default Batch_00001) and it returns the next value, incrementing the numeric suffix while preserving the zero-padding width. Start at Batch_00001, and every execution hands back one more. There's a seed input wired for the pack's control-after-generate convention, plus a harmless optional dummy_string that exists to let you force the node to run - a common trick for nudging execution order in this pack.

The mechanism that makes it tick is a persistent counter file stored by the pack (per the README's "persistent counter stored in the folder" pattern, which the same family uses for image-batch progress). That's what survives restarts.

Inputs and outputs

• name - the starting batch name. Keep the 00001 padding and the increment stays neatly aligned.
• enabled - pack-wide toggle; off returns an empty string.

Output: string - the incremented name, ready to feed a save node's filename prefix.

Where it wires in

Straight into filename prefixes: each run of a workflow saves to Batch_00003_... instead of overwriting. It composes well with InoDateTimeAsString (timestamp + batch number) and with save nodes that take a prefix string. If you're doing long unattended batch runs, this is the node that keeps every pass distinguishable.

Installing it

Part of ComfyUI-InoNodes. ComfyUI Manager → search "ComfyUI Ino Nodes" → install → restart. Manual:

cd ComfyUI/custom_nodes
git clone https://github.com/nobandegani/ComfyUI-InoNodes
cd comfyui_ino_nodes
pip install -r requirements.txt

Restart after. No keys, no models.

Common issues

The counter state is the whole gotcha. Because it persists, the node doesn't reset when you reload the workflow - if you expected to start over at 1 and it's showing 15, that's the persistent counter, and you reset it by resetting the name input. Also, don't try to increment on every image in a single batch - this increments per node execution, not per batch item; pair it with a batch-looping pattern if you need per-item numbers. And if you wire name to a fixed string from another node, the reset behavior can surprise you; keeping it as a literal is usually the saner setup.
