A few weeks ago, I shared a look at several self-hosted applications that simplify digital workflows. I have three more to discuss today, all of which share a common trait: they can be tested immediately in a web browser without the initial requirement of setting up a private server. These tools focus on utility and privacy by performing most of their tasks locally on the user’s machine rather than on a remote server.
The first tool is BentoPDF, an open-source PDF toolkit designed for privacy. Unlike many online PDF editors that require you to upload documents to their servers, Bento PDF operates entirely within the browser. If you choose to self-host it, the server merely acts as a repository for the code; the actual processing happens on your computer.
I demoed a few of its many tools in the video. One was its compression utility that I put to work on a 12-megabyte document. By applying the “photon engine” algorithm, the file size was reduced to 2.6 megabytes while maintaining legible text and clear images. I demoed another tool that allows for the creation of fillable forms from static documents. I tested this with a town building permit, adding text fields and checkboxes that functioned correctly when opened in a standard PDF reader. The application also supports annotations, such as highlighting and redactions, though it does not allow for direct editing of existing text or images.
Moving from document management to media, Retro Assembly is a library and emulation platform for retro gaming. It functions as a ROM manager that serves the game files to your browser, which then handles the emulation locally. This architecture allows for a consistent experience across different devices. I tested a game on my computer, saved the state, and was able to pick up exactly where I left off on my mobile phone.
The interface is organized similarly to media managers like Plex, automatically pulling in metadata for a clean visual library. While it supports many 8-bit and 16-bit systems, its performance on higher-end systems like the PlayStation depends on the processing power of the device you are using to play. It does not currently support certain platforms like Sega CD, but for cartridge-based games, the experience is stable.
The third application is Feed Zero, a relatively new open-source RSS reader. RSS remains a practical way to follow multiple websites in a single place, and Feed Zero offers a feature often reserved for paid services: the ability to pull in the full text of an article even if the original feed only provides a short snippet.
The application stores your subscription data and reading history locally in the browser. For those who want to sync their feeds across devices, it offers an encrypted cloud sync option where the data is secured on your device before being sent to their server. Alternatively, it can be self-hosted to keep all data within your own network. While it is still in active development—YouTube integration is currently limited—it is a lightweight and functional alternative to centralized news aggregators.
These applications demonstrate the capabilities of web browsers as application platforms. For those interested in self-hosting, tools like Unraid (compensated affiliate link) provide a straightforward entry point for managing these applications via Docker containers.
