Abstract Warehouse simulation software allows logistics managers, industrial engineers, and students to model material flows, test layout changes, and optimize operations without disrupting real-world systems. While commercial packages (e.g., AnyLogic, FlexSim, Simio) are powerful, they carry high licensing costs. This paper explores viable free alternatives—ranging from open-source general-purpose simulators to vendor-limited free editions and academic tools—highlighting their capabilities, limitations, and ideal use cases for warehouse modeling. 1. Introduction Modern warehouses face pressure to increase throughput, reduce travel time, and integrate automation (AGVs, AS/RS, pick-to-light). Simulation helps answer: How many pickers are needed? Where should fast-moving SKUs be stored? Will a new sorter create bottlenecks? Free simulation software lowers the entry barrier for small businesses, startups, and educational settings.

Grayjay is a cutting-edge mobile app that serves as a video player and source aggregator. It allows you to stream and organize videos from various sources, providing a unified platform for your entertainment needs.
Grayjay is currently available on Android, ensuring compatibility with a wide range of smartphones.
A desktop version is actively in the works, and already in internal testing phases.
Not in the near future, our focus right now is a first class Android application.
No, we are an aggregator to facilitate other streaming platforms. We do not host any content or distribute any content from servers.
Yes, we have a Gitlab repository here: Grayjay Gitlab Repository
We sell licenses.
Yes, you can change which tabs are visible, by going to settings and clicking "Manage Tabs".
The subscription tab is only visible if you have any subscriptions. It could also be located under More if you changed the tab order.
When you subscribe to a creator we store the metadata of their channel locally on your device. Your subscriptions feed is a reverse-chronological list of videos of all creators you subscribed to. We also show live streams and planned streams at the top.
Yes, Grayjay allows you to create custom playlists and organize your videos based on your preferences. You can easily categorize content, create playlists for different moods or occasions, and manage your video library effortlessly.
No, We offer a way to pay for the app once. The app will function identically without paying.
Export subscriptions in JSON format from NewPipe and then open this file in Grayjay.
Go to the sources tab, and click on the platform source you want to import from. After logging in, the "Import Subscriptions" button should be available (if the plugin supports it).
Go to the sources tab, and click on the platform source you want to import from. After logging in, the "Import Playlists" button should be available (if the plugin supports it).
Go to this website and enter the URL of your desired PeerTube instance PeerTube Plugin Host then click "Open in Grayjay" and it will offer to install that PeerTube instance as a plugin.
Using the Harbor app you can link your accounts together as a creator. Once linked, users subscribed to one of your channels, will see all of your linked channels.
The recommended way to cast is to use the FCast Receiver app. This app works on Android, Android TV, MacOS, Windows and Linux. It can be downloaded from the Google Play Store or from here https://fcast.org/. We also support casting to ChromeCast. ChromeCast at the moment is still being improved and it requires proxying streams by your phone (unlike FCast) for any content that has separate video and audio streams. Lastly, we support AirPlay. However, AirPlay does not support the DASH protocol so we do not support playing content with separated video and audio streams to AirPlay devices.
Grayjay does not track you out of the box. For this reason, platforms do not know what content to show you. If you want more personalized content you will need to login to the platforms.
Additional sources can be downloaded here.
Click on the home/subscriptions tab and click on search.
Click on the playlists tab and click on search.
Click on the creators tab and click on search.
Click on the filter button while viewing your search results and you can disable certain sources there.
You can easily refine your search results by clicking the filter button. This will display filter options applicable to all enabled sources. As you disable sources, additional filtering options may become available, since certain filters are more likely to be common across a narrower range of sources.
