I installed these 5 Docker containers, and now I don't pay for cloud apps

I used to think cloud subscriptions were the price of convenience. A few dollars for file storage here, another monthly fee for PDF editing, and suddenly I am paying for half a dozen services that all do simple jobs. That is what pushed me to take Docker seriously. Instead of continuing to rent the same basic features month after month, I started moving them onto my own hardware. After some trial and error, I ended up with five containers that cover most of what I do with paid cloud apps. Nextcloud My private cloud finally makes sense Nextcloud topping the list shouldn’t surprise anyone. Although I can use it for email, tasks, notes, project management, documents, calendars, and plenty more through its expanding collection of apps, I deliberately keep my use case much simpler. For me, Nextcloud is mainly my private alternative to Google Drive and OneDrive. I use it to sync files, photos, videos, and other media across my devices without having to depend on another paid cloud storage plan. The experience doesn’t feel like a compromise, either. Nextcloud’s web interface is polished, easy to navigate due to widgets, and feels close to a commercial cloud service. Its mobile apps are equally important to my setup. The Android app supports Material You, and I can browse my files, upload documents, and automatically back up photos straight from my phone. Outline My knowledge base lives at home Outline fills a very different role in my Docker setup. While Nextcloud handles files and media, Outline is where I keep the information I actually want to organize. I use it as my private knowledge base for project notes, research, home lab documentation, ideas, and how-to guides. Since I have used Notion before, the interface and overall functionality felt right at home. I can organize documents into collections, create nested pages, link related notes together, use templates, and rely on search when I know something is buried somewhere in my workspace. The UI is another reason I keep coming back to Outline. A lot of self-hosted tools are powerful but still look and feel outdated. Outline is the opposite. The editor is clean, the sidebar makes navigation effortless, and the overall interface feels polished. Activepieces I automated work without Zapier Activepieces is another crucial part of my Docker setup. I use it to automate repetitive tasks that I would otherwise handle manually or push through a service like Zapier. The basic idea is familiar: I pick a trigger, add one or more actions, connect the services I use, and let the workflow run in the background. Activepieces calls these automations flows, and the visual builder makes them easy to put together. It also supports human-in-loop steps, which means I can pause a workflow for an approval before it continues. Since I am self-hosting Activepieces, I am not building my entire automation setup around another cloud subscription or handing every workflow over to a third-party platform. Stirling PDF PDF tools without another subscription Stirling PDF has been one of those Docker containers I have liked for a long time. The recent UI makeover changes the equation for me. It no longer feels like a capable tool with a dated interface. The overall experience is much cleaner and more modern now. The rest of the feature set remains as it is. I can merge and split PDFs, compress large documents, convert files between different formats, reorganize and rotate pages, add watermarks, extract pages and images, work with OCR, password-protect documents, and perform plenty of other everyday PDF operations. For example, whenever I need to send a confidential document or a letter to someone, I move the file to Stirling PDF, add a password, and get the job done. Since the file never leaves my server, I have complete peace of mind about the privacy. Penpot Complete design work without Figma baggage Penpot is probably the most unexpected container in my setup. I am not a professional designer, and I don’t spend my entire day building complex interfaces in tools like Figma. But I do need to create website mockups, app concepts, dashboards, and other UI ideas from time to time. For that kind of occasional design work, Penpot has turned out to be more than enough. The interface feels familiar to Figma. I can create frames for different screen sizes, work with layers, add shapes and text, manage assets, and put together a complete page layout without much of a learning curve. Penpot also supports flexible layouts, grids, reusable design elements, and shared libraries, which become useful when I am designing multiple screens that need to follow the same visual language. I mostly use it during the early stages of a project. If I have an idea for a website, I can quickly mock up the homepage, navigation, cards, buttons, and overall layout before I start building anything. My NAS became my subscription killer I didn’t set up Docker because I wanted another technical hobby. I wanted to cut down on the number of cloud services I was paying for every month. Nextcloud handles my files, Outline gives me a proper knowledge base, Activepieces takes care of automations, Stirling PDF replaces a pile of online tools, and Penpot covers my occasional design work. There is some setup and maintenance involved, but I would rather spend a little time managing my own stack than keeping another subscription every time I need a new feature.
