YES · mature open-source replacementYes. Penpot (40k stars), Karakeep (28k stars), Krita (8k stars) are mature open-source replacements for GatherOS — self-host with docker and stop paying $4.99/mo.
People pay for the moments GatherOS removes: capture has to work from anywhere, local files must remain safe, and search, collections, boards, and social imports need to keep working as macOS, browsers, and platform response formats change. A coding agent can reproduce the local data model and a useful solo library, but the recurring value is native capture, importer maintenance, AI provider handling, and years of workflow polish.
