Runway alternatives: 7 open-source picks
Runway costs $15/mo — $180 a year. These 7 alternatives replace it for $0, led by ComfyUI, OpenMontage and LTX. All 7 are open source. License, stars and last commit checked by hand on 2026-08-29. No trials, no crippled tiers.
Images, video, masking, upscaling and effects in one graph; it replaces tools, not Runway's polish.
licenseGPL-3.0
runsyour machine or their cloud
installWindows or macOS desktop installer, Windows portable archive, or manual Python install on Windows, macOS, or Linux
enginesLocal 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
dataModels, 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
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.
setupA compatible GPU, enough VRAM and disk for multi-gigabyte models, and a working model/workflow must be chosen before useful output appears

Agentic video production system with 12 pipelines and 100+ tools covering research, scripting, assets, TTS, editing, and export from your coding assistant.

Open video generation models from Lightricks that produce high-fidelity video with synchronized audio, including local weights and a trainer.

A friendlier shell around local image and video workflows; editing remains thinner than Runway's.
licenseMIT
runsyour server
installRun the Windows installer script, the Linux launch script, or install .NET/Python/Homebrew prerequisites and run launch-macos.sh on macOS; Docker is optional
enginesUses 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
dataConfiguration, users, models, workflows, generated media, and history live in the local SwarmUI installation and configured model/output directories
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.
setupThe backend and models still have to be downloaded, and non-Windows installs require command-line prerequisites such as .NET, Python, and Git
facts verified 2026-08-10
The closest free thing to a generative video suite: local models, retakes and an actual editing timeline.
licenseApache-2.0
runsyour machine or their cloud
installDownload the Windows .exe or macOS .dmg from the project's GitHub Releases page
enginesLTX 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
dataProjects, 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
the catch vs RunwayIt is the closest integrated editor here, yet still lacks Runway's proprietary models, mature browser collaboration, and cloud-scale inference.
setupSerious 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
facts verified 2026-08-10
The rare open app with model workflows, masking and a video timeline; no included cloud render farm.
licenseAGPL-3.0
runsyour machine or their cloud
installInstall the macOS .dmg, signed Windows .exe, or Linux AppImage; Docker Compose is available for self-hosting
enginesLocal 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
dataWorkflows, 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
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.
setupNo 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

What each one is, in full: ComfyUI · OpenMontage · LTX
last updated 2026-08-29 · no votes, no pay-to-list · just what's real
how to choose a Runway alternative
Easiest to get running
ComfyUI — a one-click install, no server to maintain.
Most proven
ComfyUI, with 124,207 GitHub stars — the largest community of the 7, which usually means more answers when something breaks.
Needs real ops to self-host
LTX is capable but expects someone to run a server, updates and backups. Budget for that before choosing it.
what you give up by leaving Runway
- frontier video models
- compute
- asset history
- model updates
- commercial rights workflows
- editing polish
None of the picks above covers all of it. The full verdict says which gaps matter.

why people still pay for Runway
They pay because generative video quality and inference infrastructure are the product. If none of that applies to you, any pick above saves $180 a year.
