Open Source and Community-Driven Mac/iOS Tools: VisualDiffer, P2P, and CLI Helpers

Open-source vibes are reshaping the Mac/iOS toolkit this week. VisualDiffer is now open source, signaling a renewed life for a beloved directory-compare tool ^[1]. The outpouring from the community underscores a trust-based model where updates and fixes come from the user base itself.

• Alt-sendme — a free, open-source P2P file-transfer app that works locally or over the internet, with encryption via Iroh and no account requirements ^[2]. It’s built with Tauri and interoperable with sendme CLI, aiming to bypass central servers. A note-worthy angle: a mobile version is teased, and it’s pitched as an open-source alternative to blip. LocalSend-style speeds and QUIC+TLS 1.3 push the privacy envelope.

• Iroh and sendme CLI — the project taps into peer-to-peer connectivity with a relay-based path, while still offering a CLI option for those who don’t want a desktop client ^[2].

• Terminal & CLI backends — discussions surface about handy terminal helpers and AI-backed workflows: a Terminal App Request thread highlights autosuggestions from zsh and prompts from tealdeer-rs/tealdeer and tldr ^[3]. Another thread spots AI-driven CLI wrappers like AionUi and prompts debate around Claude Code, Codex, and Gemini CLI amid tools like Warp ^[4].

As open-source tooling spreads, trust grows through transparent updates and community-driven progress—expect more Mac/iOS tools that blur the line between GUI polish and CLI power.
