ComfyUI
open sourceGPL-3.0Local or hosted124kaug 2026Images, video, masking, upscaling and effects in one graph; it replaces tools, not Runway's polish.
The catch vs RunwayIt replaces many individual generation and masking operations, but not Runway's polished all-in-one editor, proprietary models, collaboration, or managed render farm.
Install, platforms & data +
- platforms
- desktopwebself-hostedone-click install
- install
- Windows or macOS desktop installer, Windows portable archive, or manual Python install on Windows, macOS, or Linux
- setup
- A compatible GPU, enough VRAM and disk for multi-gigabyte models, and a working model/workflow must be chosen before useful output appears
- engines
- Local and downloadable image, video, audio, 3D, and text models including Stable Diffusion/SDXL/SD3.5, FLUX, Wan, LTX-Video, HunyuanVideo, CogVideoX, and Mochi; optional API nodes connect to hosted providers
- your data
- Models, inputs, outputs, and workflow JSON live in the local ComfyUI data tree; generated media can embed workflow and seed metadata, while API nodes transmit selected inputs to their provider
- checked

SwarmUI
open sourceMITSelf-host4.4kaug 2026A friendlier shell around local image and video workflows; editing remains thinner than Runway's.
The catch vs RunwayIt is a generation front end with deep workflows, not a full replacement for Runway's timeline editing, asset management, collaboration, and proprietary models.
Install, platforms & data +
- platforms
- desktopwebself-hostedone-click install
- install
- Run the Windows installer script, the Linux launch script, or install .NET/Python/Homebrew prerequisites and run launch-macos.sh on macOS; Docker is optional
- setup
- The backend and models still have to be downloaded, and non-Windows installs require command-line prerequisites such as .NET, Python, and Git
- engines
- Uses ComfyUI as its main backend for Stable Diffusion, SDXL, FLUX, Wan, LTX, MiniMax, ACE-Step, and other image/video/audio workflows; an Automatic1111-compatible backend is optional
- your data
- Configuration, users, models, workflows, generated media, and history live in the local SwarmUI installation and configured model/output directories
- checked

LTX Desktop
open sourceApache-2.0Local or hosted1.9kjul 2026The closest free thing to a generative video suite: local models, retakes and an actual editing timeline.
The catch vs RunwayIt is the closest integrated editor here, yet still lacks Runway's proprietary models, mature browser collaboration, and cloud-scale inference.
Install, platforms & data +
- platforms
- desktopone-click install
- install
- Download the Windows .exe or macOS .dmg from the project's GitHub Releases page
- setup
- Serious local generation currently needs a high-end NVIDIA Windows GPU and very large model downloads; macOS generation relies on an API key instead of local inference
- engines
- LTX video models and bundled image-generation components, with optional LTX API and other configured hosted services; local generation is primarily supported on NVIDIA Windows systems
- your data
- Projects, settings, logs, downloaded models, source assets, and renders live in the platform-specific LTXDesktop application-data folder; API mode uploads the material needed for the requested generation
- checked

NodeTool
open sourceAGPL-3.0Local or hosted450aug 2026The rare open app with model workflows, masking and a video timeline; no included cloud render farm.
The catch vs RunwayIt combines model workflows, masking, and a timeline, but requires BYOK or local setup and lacks Runway's polished team and editor ecosystem.
Install, platforms & data +
- platforms
- desktopwebself-hostedclione-click install
- install
- Install the macOS .dmg, signed Windows .exe, or Linux AppImage; Docker Compose is available for self-hosting
- setup
- No useful model or provider is bundled: the user must add an API key or download a multi-gigabyte local model, and some local backends add a large Python/Conda environment
- engines
- Local Ollama, llama.cpp/GGUF, MLX, Nunchaku, Hugging Face, and diffusion/media models, plus BYOK providers such as OpenAI, Anthropic, Gemini, FAL, Replicate, KIE, ElevenLabs, and Hugging Face
- your data
- Workflows, projects, assets, files, provider settings, and vector indexes live locally in YAML, SQLite/SQLite-vec, and application storage; optional S3 or Supabase storage is supported, and cloud nodes transmit their inputs
- checked

Draw Things
freeGPL-3.0Local or hostedLocal image and video generation on Apple hardware; a creator suite only if your editor lives elsewhere.
The catch vs RunwayIt handles generation and some edits locally, but remains an Apple-only generator rather than Runway's cross-platform collaborative creative suite.
Install, platforms & data +
- platforms
- desktopmobileone-click install
- install
- Install the signed app from Apple's App Store on macOS, iPhone, or iPad
- setup
- Apple hardware is required, and the first model download is large; older devices can be slow or memory-limited
- engines
- Runs supported Stable Diffusion, SDXL, FLUX, and video models locally, including imported checkpoints and LoRAs; optional cloud compute can offload generation
- your data
- Projects, models, history, and generated media live in the app sandbox; on macOS model files are under the app container, while cloud offload sends prompts and media for processing
- checked

WanGP
freeproprietary, freeLocalA broad local image-and-video workbench; generation is free, the proprietary Runway models are not included.
The catch vs RunwayIt covers more local models than Runway exposes, but lacks Runway's cohesive editing suite and team-oriented cloud workflow.
Install, platforms & data +
- platforms
- desktopwebself-hostedclione-click install
- install
- Run the supplied Windows install.bat or Linux/macOS install.sh script; community launchers such as Pinokio are optional
- setup
- Installation must match the GPU and PyTorch/CUDA/ROCm stack, and useful models consume many gigabytes of disk and substantial VRAM
- engines
- Local video, image, music, speech, and restoration models including Wan, MiniMax/Hailuo-family weights where available, LTX, Hunyuan, LongCat, Qwen Image, Z-Image, FLUX, ACE-Step, and Qwen TTS

Frequently Asked Questions
Direct answers · Runway open-source replacements
What is the best free alternative to Runway?+
The top free alternative to Runway is ComfyUI (open source, GPL-3.0). Images, video, masking, upscaling and effects in one graph; it replaces tools, not Runway's polish. Other popular Runway replacements include SwarmUI, LTX Desktop, NodeTool.
Can I self-host a free replacement for Runway?+
Yes. Of the 6 free alternatives to Runway, 6 can be self-hosted on your own server or local machine: ComfyUI (GPL-3.0), SwarmUI (MIT), LTX Desktop (Apache-2.0), NodeTool (AGPL-3.0), Draw Things (GPL-3.0), WanGP (proprietary, free).
How much does switching from Runway to a free alternative save?+
Runway starts at $15/month per seat ($180/year). Switching a 5-person team to a free alternative like ComfyUI saves $900 per year in software subscription fees.
Should I vibe-code or build my own Runway clone from scratch?+
Our build verdict for Runway is NOT REALLY (use a free alternative, save the tokens). A UI around video models is buildable; the video-generation model quality, compute, safety, editing stack, and continuous research are not a solo afternoon project.
What is the catch when switching from Runway to ComfyUI?+
It replaces many individual generation and masking operations, but not Runway's polished all-in-one editor, proprietary models, collaboration, or managed render farm.
