ArchiveBox is a self-hosted web archiving tool that saves full local copies of web pages as HTML, screenshots, PDFs, and media. It protects your research and references against link rot and platform takedowns by keeping the source on your own disk. Sites with heavy JavaScript or paywalls archive imperfectly, and storage grows fast.

Home Assistant is an open-source smart home platform that runs locally and connects thousands of devices without sending your home's activity to vendor clouds. It keeps automation working even when the internet is down and stops appliances from reporting on you. Expect a learning curve and occasional breakage when integrations change.

Immich is a self-hosted photo and video backup service with automatic phone uploads, face recognition, and search, built as a direct replacement for Google Photos. Your entire photo history stays on a server you control instead of feeding a cloud provider. It moves fast as a project, so updates occasionally require migration steps.

Jellyfin is a free, open-source media server that streams your own movie, music, and TV library to any device, with no accounts, tracking, or subscription. It replaces Netflix-style apps for media you actually own. You supply the files, the storage, and the server, and remote streaming requires some network setup.
