    ComfyUI

    open sourceGPL-3.0Local or hosted
    124kaug 2026

    Images, video, masking, upscaling and effects in one graph; it replaces tools, not Runway's polish.

    The catch vs Runway

    It 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

    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

    SwarmUI

    open sourceMITSelf-host
    4.4kaug 2026

    A friendlier shell around local image and video workflows; editing remains thinner than Runway's.

    The catch vs Runway

    It 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

    Configuration, users, models, workflows, generated media, and history live in the local SwarmUI installation and configured model/output directories

    LTX Desktop

    open sourceApache-2.0Local or hosted
    1.9kjul 2026

    The closest free thing to a generative video suite: local models, retakes and an actual editing timeline.

    The catch vs Runway

    It 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

    NodeTool

    open sourceAGPL-3.0Local or hosted
    450aug 2026

    The rare open app with model workflows, masking and a video timeline; no included cloud render farm.

    The catch vs Runway

    It 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

    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

    Draw Things

    freeGPL-3.0Local or hosted

    Local image and video generation on Apple hardware; a creator suite only if your editor lives elsewhere.

    The catch vs Runway

    It 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

    WanGP

    freeproprietary, freeLocal

    A broad local image-and-video workbench; generation is free, the proprietary Runway models are not included.

    The catch vs Runway

    It 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

    Downloaded models, presets, queues, galleries, generated media, and metadata live in the local installation tree and chosen output folders

Frequently Asked Questions

Direct answers Β· 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.
