Mountain Duck

Mountain Duck is a file client for macOS and Windows that mounts Amazon S3, Google Drive, Dropbox, OneDrive and other cloud providers, plus FTP, SFTP, WebDAV and rsync servers, as local drives. Applications open and edit remote files directly, system search reaches inside remote storage, and you choose between local caching and on-demand streaming.

Little Snitch

Little Snitch is a host-based macOS application firewall. Unlike a conventional packet filter that works on ports and addresses, it operates at the application level, so a rule applies to one program rather than everything sharing a port. A live searchable Network Monitor shows each connection's remote host, Quick Blocking refuses a connection on the spot, and block lists flag chatty software.

Inkscape

Inkscape is a free, open-source vector graphics editor for Windows, macOS and Linux that reads and writes SVG natively, so artwork stays resolution-independent at any scale. It offers node-level path editing, shape tools, gradient and pattern fills, text on a path, layers, cloning, bitmap tracing and thousands of extensions, exporting to common raster and print formats.

Fluent Reader

Fluent Reader is a local-first open-source RSS reader for macOS, Windows and Linux that keeps feeds and your read-later list on your own machine. A full-text search engine indexes article bodies rather than only headlines, a reading pane strips page clutter down to text and images, and browser extensions capture subscriptions from the page you are reading.
