InvokeAI vs ComfyUI

InvokeAI and ComfyUI are both free, open-source frontends for running Stable Diffusion models locally on your own hardware. InvokeAI focuses on a polished, Photoshop-style canvas experience. ComfyUI uses a visual node editor that exposes every step of the generation pipeline. Here's how they compare across six categories.

Key Takeaway — March 2026

ComfyUI wins 3 of 6 rounds, InvokeAI takes 1, and 2 are a draw. If you want maximum flexibility, first-day model support, and better VRAM efficiency — ComfyUI is the stronger pick. If you want a clean canvas UI for inpainting and outpainting without touching nodes — InvokeAI is hard to beat. If you'd rather skip the setup entirely, LocalForge AI ships a pre-configured local environment with no install steps.

Round 1: Ease of Setup

InvokeAI ships a standalone installer for Windows, Mac, and Linux. You can also install via Pinokio in roughly 10 minutes. The setup wizard walks you through model downloads and GPU detection. It's straightforward, but the Python environment can still trip up first-timers if something goes wrong.

ComfyUI launched a Desktop app in early 2025 that bundles Python, dependencies, and sample workflows into a one-click installer. That Desktop version captured an estimated 72% of new installations in its first year. Manual install via Git still works for advanced setups.

Winner: Tie. Both tools now have one-click installers. ComfyUI Desktop edges ahead on bundled workflows; InvokeAI's wizard is more guided. Neither is hard.

Round 2: UI & Workflow

InvokeAI gives you a traditional form-based interface with tabs for generation, canvas, upscaling, and video. The Unified Canvas — upgraded in v6.0 (mid-2025) — is InvokeAI's standout feature. You paint masks, sketch rough doodles, and inpaint/outpaint directly on the canvas. It also has a node editor, but most users never open it.

ComfyUI is a node editor first. You wire together checkpoint loaders, samplers, VAE decoders, ControlNets, and LoRAs into visual pipelines. Workflows save as JSON or embed into generated images as metadata — anyone can drag an image onto ComfyUI and recreate the exact pipeline. The March 2026 App Mode update added the ability to wrap workflows into simple UIs for non-technical users.

Winner: InvokeAI. For the 80% of people who want to type a prompt, tweak settings, and paint corrections, InvokeAI's canvas is faster and friendlier. ComfyUI's node graph is more powerful but demands real investment — Reddit users consistently compare it to "C vs Python."

Round 3: Model Support & Flexibility

InvokeAI supports SD 1.5, SDXL, and Flux models. It added Flux Kontext Dev support in v6.0 and FLUX.2 Klein in early 2026. Model additions are curated by the dev team, which means they're stable but arrive weeks to months after release. LoRA support was limited for a long time (no processing past the 77th token for ages), though recent versions have closed that gap.

ComfyUI gets new models first — almost without exception. SD3, Flux, PixArt, CosXL, Wan2.1 video, HunyuanVideo, and Wan2.2 all landed on ComfyUI before any other frontend. The custom node ecosystem (2,000+ nodes on the ComfyUI Manager) means community members often add support for new architectures within days. ComfyUI also handles image, video, 3D, and audio generation workflows.

Winner: ComfyUI. It's not close. ComfyUI is the first frontend to support virtually every new open-source model. InvokeAI's curated approach is more stable but consistently behind.

Round 4: Performance & Hardware

InvokeAI runs on GPUs with as little as 4 GB VRAM. In practice, users on 8 GB cards (RTX 2070 Super, RTX 3060) report that SDXL models run slightly slower than on ComfyUI, and Flux models are significantly slower. A GitHub issue (#7612) documents Flux generation in InvokeAI taking roughly 2x longer than ComfyUI on identical hardware, with OOM errors at resolutions where ComfyUI runs without tiling.

ComfyUI is built for memory efficiency. It only loads and executes the nodes present in your graph, so it doesn't waste VRAM on unused features. Users on r/StableDiffusion consistently report fewer "CUDA out of memory" errors compared to A1111, Forge, and InvokeAI. On an 8 GB card with Flux, ComfyUI generates at speeds users call "acceptable" while InvokeAI struggles.

Winner: ComfyUI. Better VRAM management and measurably faster generation, especially on Flux models and cards with 8–12 GB VRAM.

Round 5: Community & Ecosystem

InvokeAI has ~27,000 GitHub stars, an active Discord, and an Apache 2.0 license (commercially friendly — no copyleft obligations). The hosted Invoke platform shut down in 2025, but the open-source Community Edition continues under community stewardship. Development pace is steady but slower than ComfyUI's.

ComfyUI is backed by Comfy Org and endorsed by Stability AI as one of two "official" UIs. The r/comfyui subreddit, Discord, and community sites like CivitAI and RunComfy host thousands of shareable workflows. The custom node ecosystem is massive — 2,000+ nodes covering everything from tiled upscaling to audio generation. The March 2026 App Mode and ComfyHub launch made sharing even easier.

Winner: ComfyUI. Larger ecosystem, faster development cycle, more shareable workflows, and official backing from Stability AI.

Round 6: Offline / Local Capability

InvokeAI runs 100% locally. No internet connection required after initial model downloads. All data stays on your machine. The Apache 2.0 license means no restrictions on commercial use of derivative works.

ComfyUI also runs 100% locally with no phone-home requirements. Workflows, models, and outputs all stay on-device. It's fully open-source under the GPL license (which requires derivative works to also be open-source if distributed).

Winner: Tie. Both are fully offline, fully local, and free. The licensing difference matters if you're building a commercial product on top of the code — Apache 2.0 (InvokeAI) is more permissive than GPL (ComfyUI).

ComfyUI is the better tool for most local AI image generation work in 2026. It's faster, supports more models, and has a larger ecosystem. InvokeAI remains the best pick if your workflow centers on inpainting, outpainting, and canvas-based editing — its Unified Canvas is still the most intuitive painting interface in any SD frontend. Many serious users run both: ComfyUI for complex generation pipelines, InvokeAI for touch-up and editing.

Frequently Asked Questions

Is InvokeAI or ComfyUI easier for beginners? +
InvokeAI is easier. It has a traditional UI with tabs and a canvas — you type a prompt and click generate. ComfyUI uses a node editor that takes hours to learn. However, ComfyUI's Desktop app (released early 2025) and App Mode (March 2026) have lowered the barrier.
Which is faster, InvokeAI or ComfyUI? +
ComfyUI is faster in most tests. It manages VRAM more efficiently and only loads what your workflow needs. On 8 GB cards running Flux, users report ComfyUI generating at roughly 2x the speed of InvokeAI on identical hardware.
Can InvokeAI and ComfyUI run the same models? +
Both run SD 1.5, SDXL, and Flux checkpoints. ComfyUI supports a wider range of models (PixArt, CosXL, Wan video, and others) through its custom node system. InvokeAI's model support is curated and arrives later.
Do InvokeAI and ComfyUI work offline? +
Yes. Both run 100% locally after you download your models. No internet connection or cloud account is required for generation.
Can I use both InvokeAI and ComfyUI together? +
Yes. Tools like StabilityMatrix let you install multiple UIs sharing the same model files. Many users run ComfyUI for complex pipelines and InvokeAI for inpainting and canvas work.
Is InvokeAI still being developed after the hosted platform shut down? +
Yes. The open-source Community Edition continues under active development. Version 6.0 launched in mid-2025 with a redesigned canvas and Flux Kontext support. The GitHub repo (~27,000 stars) receives regular commits.
