Kopia does encrypted, deduplicated snapshots, like Restic, and it also ships a graphical window and a server mode. Backends include local disks and the usual cloud buckets. It is open source and cross-platform. People who will not live in a terminal can start here. The project is younger than Borg. The GUI hides choices you […]
7-Zip opens almost every archive you will be sent and can create 7z and ZIP files encrypted with AES-256. It is free, by Igor Pavlov, and the Windows program is the one everyone means. It is light and it does not bundle a browser. The window looks old because it is a compression tool. On […]
Restic makes encrypted, deduplicated snapshots and can send them to a local folder, SFTP, or object storage such as Backblaze B2 and S3. It is a single program, written in Go, and the same binary runs on the major desktops. The repository format is restic’s, not a pile of zip files you can open by […]
Magic Wormhole sends a file with a short code you read aloud. See how the free tool encrypts the handoff, what a relay can see, and who it is for.
Croc sends files between two computers with a code phrase, resumes if the connection drops, and runs on the major desktops. One binary, no account, encryption between the two ends. The usual author is the developer known as schollz. By default the introduction goes through a public relay. A public relay sees that a transfer […]
Syncthing keeps folders the same across computers you own. The devices talk to each other, encrypted, with no account and no company in the middle. It is open source. You approve each device. After that, changes flow. A delete flows too. Syncthing is not a backup. If ransomware encrypts the folder on one machine, the […]
BorgBackup stores encrypted, deduplicated, compressed archives on a disk or a server you control. The tool is aimed at people who will use a terminal. Daily backups stay small because unchanged chunks are not stored again. You can prune old archives and still restore a file from last month. Borg wants Borg on the far […]
LocalSend moves files between phones and computers on the same local network. No account, no size cap from a company, no cloud. It is open source and runs on Android, iOS, Windows, macOS, and Linux. Nearby devices see each other and you accept the transfer. It is not a way to send a file across […]
Ente Auth stores TOTP codes with end-to-end encryption and syncs them across Android, iPhone, desktop, and the web. It comes from the same people as Ente Photos. You can keep codes on one device without an account. Sync means an account, and the codes are still encrypted with keys you hold. They have published audits. […]
KeePassXC can store TOTP secrets in the same encrypted database as your passwords. The browser extension can type the code. There is no second cloud and no second app from this team. The threat model matches the password vault: whoever can open the file can mint codes. That is also the downside. Password and second […]
