**Short answer (2026):** Install **ComfyUI Manager** first — it's how you install and manage everything else. Then get the **Impact Pack** for face fixing (FaceDetailer) and segmentation — it's the most-downloaded pack after Manager. From there, add packs for upscaling, control, and utility nodes as your workflows demand.

- **Install first, always:** ComfyUI Manager
- **Biggest quality jump:** Impact Pack (FaceDetailer)
- **Rule:** add nodes when a workflow needs them, not speculatively

## 1. ComfyUI Manager — install this before anything else

Manager is the package manager for ComfyUI: it discovers, installs, updates, and manages every other custom node. In the 2026 update it moved to an integrated "manage extensions" system with a card-based layout (category, description, node list, preview). **Don't hand-install other nodes before Manager — it makes the rest painless.**

## 2. Impact Pack — the single biggest quality upgrade

The Impact Pack is a toolkit for detection, segmentation, and detail enhancement — over 25% of all custom-node downloads. The headline node:

- **FaceDetailer** — auto-detects faces, re-renders them at higher resolution, and blends them back in. It single-handedly took ComfyUI portraits from good to excellent. If your faces come out mushy, this fixes it.
- **Segmentation nodes** — isolate faces/bodies/objects to apply different processing or precise masks to specific regions.

## The rest, by job

| Need | Pack / node |
|------|-------------|
| Manage everything | **ComfyUI Manager** (first) |
| Fix faces, mask regions | **Impact Pack** (FaceDetailer, SEGS) |
| Upscale to high-res | Upscale model nodes + **Ultimate SD Upscale** (see below) |
| Efficient multi-LoRA / compact graphs | **Efficiency Nodes** (LoRA Stacker) |
| Pose/depth/edge control | **ControlNet** aux preprocessors |
| Quality-of-life / logic | rgthree-comfy, WAS Node Suite |

## How to install a custom node

Easiest: open **Manager → Manage Extensions**, search, click install, restart. Manual: `git clone` the repo into `ComfyUI/custom_nodes` and restart. Manager also flags missing nodes when you load a workflow that needs them — one click to install them all.

## Frequently asked questions

### What ComfyUI custom node should I install first?
ComfyUI Manager, always. It's the tool you use to find, install, update, and repair every other custom node — installing others by hand first just makes life harder.

### What does the Impact Pack do?
It adds detection, segmentation, and detail-enhancement nodes. Its FaceDetailer node automatically re-renders faces at higher resolution for dramatically better portraits, and its segmentation nodes enable precise regional edits and masks.

### How do I install ComfyUI custom nodes?
Use ComfyUI Manager (Manage Extensions → search → install → restart), or `git clone` the node's repo into `ComfyUI/custom_nodes`. Manager can also auto-install any nodes a loaded workflow is missing.

### Do custom nodes slow ComfyUI down?
A large number can increase startup time, but well-maintained packs like Manager and Impact Pack have negligible runtime cost. Add nodes as workflows need them rather than installing dozens speculatively.

## Conclusion

You don't need 40 packs — you need the right few. Manager to run the show, Impact Pack for faces and masks, then upscaling/control/efficiency nodes as your workflows grow. Which custom node can you not live without? Drop it in the comments.
