KeeWeb can create password vaults or open KDBX databases produced by KeePass, KeePassXC, and compatible tools. It runs in a browser or as a desktop application on Linux, Windows, and macOS. Vaults may remain as local files or be stored through Dropbox, Google Drive, or OneDrive, and the web edition can be self-hosted for greater control over deployment.

This is the official client for the Mullvad VPN service across desktop and mobile platforms. It supports WireGuard connections and options such as multihop routing, traffic obfuscation, custom DNS, content blocking, and controlled local-network access, while split-tunneling availability varies by platform. Mullvad publishes signed builds and external audit reports for the app. A Mullvad VPN service account is required to use it as a VPN client.

Zen runs a local system proxy on Windows, macOS, and Linux to block ads, tracking scripts, malware, and other unwanted requests from browsers, desktop applications, and operating-system components. Users can inspect blocked requests and the rule that matched, then use bundled filters or add hosts files and EasyList-style lists. The first run requires installing a root certificate generated locally so HTTPS traffic can be inspected. On Linux, automatic proxy configuration is currently limited to GNOME- and KDE-based desktops.

mhrv-rs runs a local HTTP and SOCKS5 proxy that forwards requests through a Google Apps Script deployed under your own account, concealing the destination from the ISP at the TLS SNI layer. Setup requires creating the relay, choosing an auth secret, installing a local certificate, and configuring the browser or system proxy. Google can still see destination sites, and Apps Script quotas or unsupported video CDNs can limit usage.
