LLMStack vs Runway
Side-by-side comparison · Updated September 2026
| Description | LLMStack is a source-available builder for AI agents, workflows and chatbots that combine model calls with your own data. Its visual builder can chain multiple models and connect data sources, making it more suitable for assembling an application or process than for simply opening a personal chat app. The project documents deployment on your own infrastructure and points to Promptly as its hosted offering. Supported data inputs include documents, websites and connected sources such as Google Drive and Notion. The builder provides preprocessing and vectorization for retrieval workflows. Apps can be shared publicly or with selected people, and viewer and collaborator permissions control access to shared work. The repository also documents HTTP API access and Slack or Discord triggers. Plan for infrastructure, model-provider usage, credentials and permissions as separate decisions. Installing a self-hosted builder does not make externally hosted models free or keep every data request local. Start with a limited workflow and representative documents, review the generated output, and confirm the permissions required by each connected source before expanding access. Compare AnythingLLM when a document-chat workspace is the main need; LLMStack is oriented toward composing the application and its workflow. | Runway is a creative platform for generating and editing video, images and related media. It is operated by Runway AI, Inc. For an image-to-video experiment, begin with a reference image and a short motion brief, then choose a model available in your account. A generated shot can help explore a scene or campaign direction, but it still needs review for continuity, faces, text and product details before joining a finished sequence. The Free plan provides 125 credits once and 5GB of asset storage. Runway's help page says these deposited credits do not expire, but they do not replenish after spending; a Free account cannot buy additional credits without upgrading. Videos generated on Free carry a watermark. The available free models change, so the initial balance does not guarantee a particular image-to-video model, duration or resolution. Check the current tool selector and the charge shown for the intended generation. Current individual monthly plans are Standard at $15 for 625 credits, Pro at $35 for 2,250 credits and Max at $95 for 9,500 credits. Annual billing displays monthly equivalents of $12, $28 and $76. Standard lists 20GB storage, up to three projects, five parallel video/image generations, no watermarks and 4K upscaling. Pro lists 100GB storage, up to five projects, fifteen parallel generations, a Brand Kit, a custom voice clone and Runway MCP. Max lists 500GB storage, up to ten projects, twenty parallel generations and one-month credit rollover. These are separate plan allowances, not unlimited video-generation promises. The paid model table provides a useful cost example: Gen-4.5 is listed at 60 credits for five seconds. On that setting, ten attempts would use 600 of Standard's 625 monthly credits. That calculation does not measure success rate or include other work, and it does not establish Free access to Gen-4.5. Budget retries and finishing work separately. Model choices and credit prices should be checked again when the project starts. Team and Enterprise have a separate pricing view. Team is shown at $69 per seat per month on monthly billing with a minimum of two users; Enterprise asks customers to contact sales for custom credits and requirements. Compare storage, shared projects, account controls and delivery needs before selecting a team plan. Developer API pricing is also separate from the individual plan comparison. Runway's terms say it does not claim ownership of compliant inputs or outputs and does not restrict commercial use of outputs under the agreement. This does not clear third-party rights or guarantee copyright protection. The terms also describe using content to improve or train models; Enterprise advertises a separate no-training condition, so assess the agreement applicable to your account before submitting confidential assets. We reviewed published product and plan information without benchmarking generated clips. Pika and Vheer offer alternative starting points for short image-to-video experiments with their own credits and export conditions. |
