Decimen Optical Transfer is an open-source browser-based file-transfer tool by Evan Crawley that sends files between devices using only a screen and a camera, without a network connection, pairing, permissions beyond camera access, or a dedicated app. The sender displays an endless stream of animated QR codes; the receiver collects fountain-coded frames in any order and uses Luby transform decoding to reconstruct the payload, so dropped frames affect transfer time rather than correctness. Transfers preserve filenames and media types, accept pasted text, support files up to 64 MB, and verify completed payloads with SHA-256. The web app works offline after its first visit and can be installed on iOS and Android home screens. QR streams can also be exported as APNG or PNG sequences for playback from a file, page, or video. Transmissions are not encrypted: data is readable by any camera pointed at the sending screen. The project is licensed under AGPL-3.0-or-later as of v0.4.0; releases through v0.3.0 remain available under the MIT license.

Blaxel is an infrastructure platform for autonomous AI agents that provides isolated microVMs (which boot in milliseconds and resume in ~25ms), persistent shared memory, and programmable networking to run, connect, and operate agents at scale. It offers a distributed shared-storage feature (presented in videos as "Agent Drive") that can be mounted as a POSIX-style drive so agents in separate sandboxes can share files, cache dependencies, exchange context/memory, and coordinate parallel work in real time.

QRFerry transfers files between two devices as a live animated QR stream. The sender and receiver run in the browser, and the file is not uploaded to an application server. The protocol optionally compresses the file with Brotli or gzip, then divides the payload into QR frames containing binary headers, RaptorQ source or repair symbols, and CRC-32 checksums. Fountain coding lets the receiver reconstruct the file from enough unique symbols while tolerating blurred, missing, out-of-order, or mid-stream frames. The receiver verifies frame, compressed-payload, RaptorQ-object, and original-file checksums before saving the file. QR rendering, scanning, and RaptorQ encoding and decoding use WebAssembly implementations of fast_qr, ZXing-C++, and an RFC 6330 RaptorQ implementation.

flipflop is an open-source file- and text-sharing tool that establishes a trusted tunnel between two or more devices, allowing subsequent transfers without repeated pairing codes. It uses Iroh to connect devices over Bluetooth, a local network, or the internet, including automatic NAT traversal, and can share files, links, and plain text. Builds are provided for Linux, macOS, Windows, and Android; an iOS build is not available.

Blip is a Linux iMessage client for the Omarchy bar and desktop, developed by Fred Nix and contributors. It uses an existing Mac signed into Messages as a gateway: Linux tools communicate with Mac-side bridge tools over SSH, which read the Mac's chat database and use Messages.app automation to send messages. The Linux client renders conversations, group chats, unread indicators, notifications, search, link previews, photos and files, while a Mac-side watcher provides near-real-time updates. Blip requires an awake, reachable Mac running macOS 13 or newer, with Messages in iCloud, SSH key authentication, and the required macOS permissions. It does not use a hosted server, telemetry, or a Linux-side message cache; message text and attachment data travel through the SSH connection, although opened attachments and link previews may be cached locally. It is distributed as an Omarchy/Quickshell plugin with TypeScript, QML, and Mac bridge tools under the MIT license.
