Inlark

Inbix is an open-source, Cloudflare-native email API platform that provides REST APIs, SDKs and an MCP for generating inboxes, receiving emails, and building email automation. It is distributed as an open-source project aimed at developers building mail-handling workflows.

Flectar Mail is a native, open-source email, calendar, and contacts client built with Rust. It uses a local-first data path, stores synced mail and calendar data locally for offline use, and connects to Gmail, Outlook, Microsoft 365, IMAP/SMTP, JMAP, CalDAV, and CardDAV services. Instead of opening email in a WebView, Flectar Mail renders HTML and CSS through Blitz, a Rust renderer from the Dioxus team. It does not execute email scripts and blocks remote images by default; HTML rendering remains experimental, so complex messages may display incorrectly. The client also provides local access to attachments and WebDAV/JMAP files, account signatures, and desktop OpenPGP/MIME signing and encryption through installed GnuPG 2.x. The project is licensed under the GNU Affero General Public License v3. It provides desktop builds for Linux, Windows, and macOS, plus an experimental Android APK, and can be built from source with Rust. It is currently in development and not yet stable; early releases require users to configure their own OAuth applications for Gmail and Outlook or use IMAP/JMAP accounts.

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.

Agentic Inbox is a self-hosted email client from Cloudflare that runs on Cloudflare Workers through the user's Cloudflare account. It receives and sends mail through Cloudflare Email Routing, isolates each mailbox in a Durable Object with SQLite storage, and stores attachments in R2. The web interface supports threaded replies and forwards, rich-text composition, folders, search, and attachments. Its built-in AI agent, using the Cloudflare Agents SDK and Workers AI, can read inboxes, search conversations, draft replies, and send messages through email tools; automatic drafts for incoming mail require explicit confirmation before sending. Deployment provisions Workers, Durable Objects, R2, and Workers AI, and the setup requires Cloudflare Access, Email Routing, Email Service, and a mailbox on the configured domain.

Inline is a work-chat app for teams, built by a two-person team. Its macOS and iOS clients organize conversations around numbered, optionally titled threads, direct messages, Spaces, and a sidebar of chats requiring attention. The project is designed for focused asynchronous and real-time collaboration, including sharing links to threads and using them for feedback, bug tracking, specifications, brainstorming, meeting notes, and team libraries. The app targets fast startup, low CPU and RAM usage, and high frame rates. The video describes voice and screen sharing and a Rust-based WebRTC stack; the repository also lists a public API, command-line interface, SDKs, bot integrations, a hosted MCP server, and plugins for AI clients and OpenClaw. macOS and iOS are in beta, while web, Android, Windows, and Linux support are planned. Inline is currently free to use and in beta. The repository states that its server and native client source code are closed for now, while the protocol, CLI, MCP server, SDKs, plugins, and related development packages are published under the Apache License 2.0. The repository is the official source for building on top of Inline, not for the closed core application.
