VERT

Should I vibe-code or build my own FileChanger clone from scratch?+
Our build verdict for FileChanger is YES (the core loop fits in a weekend). The conversion is other people's software. Pandoc, ImageMagick and FFmpeg do the actual work, the format list looks enormous because those three projects are enormous, and a coding agent can wire all of them behind an upload form and a REST endpoint in one sitting. What a subscription buys is not the conversion, it is somebody else running a box that eats untrusted files from strangers all day without falling over, and keeping a few hundred format pairs working after every upstream release. Point it at your own files on your own machine and most of that risk simply is not yours, which is why this one is a yes.
What is the catch when switching from FileChanger to Pandoc?+
It only handles document formats from the command line, with no image, audio or video conversion and no hosted API.
