OpenGranola is an open-source project designed to provide a lightweight and extensible framework for building AI-powered applications with a focus on modularity and developer simplicity. It aims to streamline the process of integrating language models into real-world workflows by offering a structured environment where components such as prompts, tools, and execution pipelines can be composed and reused. The project emphasizes clarity and minimalism, reducing the complexity often associated with orchestration frameworks while still enabling powerful interactions between AI agents and external systems. OpenGranola allows developers to define workflows declaratively, making it easier to test, iterate, and maintain AI-driven logic without deeply coupling it to infrastructure. It is particularly suited for rapid prototyping as well as production-ready pipelines that require flexibility and transparency.

XFolder is a modern file manager designed specifically for macOS. It integrates core features such as multi-pane views, a smart directory tree, and multi-tab management, aiming to provide a more efficient and flexible file browsing experience than Finder.

FSNotes is a modern notes manager for macOS and iOS. App respects open formats like GitHub Flavored Markdown, so you can easily write documents on iPhone and MacBook. It's simple and blazing fast! Sync via iCloud Drive. 3D Touch and configurable keyboard. TextBundle and EncryptedTextBundle containers. Pinned notes are kept in sync with the desktop app. Dynamic fonts (iOS 11+). Night mode by location or screen brightness. Sharing extension. Encrypted note support.

Simplenote for macOS is the official native macOS application for the Simplenote service, giving Apple computer users a dedicated environment to write, organize, and sync notes with the same simplicity found on other platforms. Built using macOS frameworks and powered by the Simperium synchronization protocol, it ensures that any text or Markdown notes you create are automatically backed up and kept in sync with Android, iOS, web, and other clients. The app supports fast searching and tagging so users can keep large collections of notes orderly, and has features like history or revision views to recover previous edits. macOS integration means users benefit from keyboard shortcuts, native window management, and system services like Spotlight search to find notes instantly. As a GPL-licensed open-source project, it invites contributions and learning, letting developers tweak UI or add platform-specific enhancements without being locked into a proprietary ecosystem.

Adrafinil is an open-source macOS utility that prevents a Mac from sleeping while AI coding agents are actively working. It automatically detects agent activity through integrations with Claude Code, Codex, Cursor, Gemini CLI, and other development assistants. A privileged helper enables continued operation when a MacBook lid is closed. Each agent session receives an independent sleep-prevention hold that ends when its work finishes. Overlapping sessions keep the computer awake until all active holds are released. Thermal protection prevents excessive heat during unattended operations. Abandoned session detection automatically removes unnecessary holds. Users can configure manual or timed controls through the menu bar, command-line interface, and MCP integrations. Optional activity summaries provide information about recent agent operation.

Biscotti is a privacy-focused meeting recording and transcription application built natively for macOS. It captures microphone and system audio from virtual meetings or in-person conversations without requiring a bot to join calls. The application processes recordings locally using on-device speech recognition and AI models. It generates speaker-labeled transcripts, meeting summaries, action items, and suggested titles. Calendar integration helps identify upcoming meetings, while automatic call detection can stop recordings when conversations end. Users can add timestamp-linked Markdown notes and configure custom vocabulary for specialized terminology. Biscotti also provides MCP integration for interacting with meeting records through compatible AI applications, keeping recordings and transcripts stored locally rather than in the cloud.

Capsomnia is a lightweight, open-source macOS utility that transforms the Caps Lock key into a physical switch for preventing system sleep. It enables MacBooks to continue running background tasks even when their lids are closed. Users can activate sleep prevention by enabling Caps Lock and restore normal behavior by disabling it. The application is useful for long-running development tasks, AI agents, downloads, remote access, and unattended scripts. Its menu bar interface provides status indicators, customizable keyboard shortcuts, and automatic shutdown timers. Optional settings preserve display availability for remote graphical operations and prevent unwanted uppercase typing. Capsomnia also offers hotspot connectivity maintenance, automatic startup, and optional command-line integration without requiring accounts or collecting telemetry.

Repeat is a lightweight Swift timer library built on Grand Central Dispatch as an alternative to NSTimer. Its compact APIs create repeating or one-time timers that can operate on background queues. Timer instances can be paused, started, resumed, and reset without creating replacements. Multiple observers can subscribe to the same timer, while weak callback references help reduce unwanted retention. Repeat supports infinite, finite, and single-fire execution modes and exposes observable timer states. It also includes dedicated debouncer and throttler utilities for controlling how frequently blocks of code are executed.

Simplenote for iOS is the official iPhone and iPad client for the cross-platform Simplenote note-taking ecosystem, providing iOS users with a clean, responsive interface to create, edit, and manage plain-text notes. It syncs seamlessly with Simplenote’s cloud infrastructure so that notes created on a phone instantly appear on web, Android, macOS, or desktop apps without manual steps. On iOS, users can search quickly across all notes, organize content with tags, and use native iOS behaviors such as swipe gestures, system share sheets, and keyboard shortcuts for efficient workflow. With Markdown support, notes can include basic formatting and previewing, letting writers structure content easily without clutter. The repository includes setup guidance for building and running the app with proper credentials for the syncing service, showing that the codebase gives contributors a practical foundation for experimenting or extending capabilities.

dmenu-mac is a lightweight, keyboard-driven application launcher for macOS inspired by the Linux dmenu utility. It opens through a configurable keyboard shortcut and provides instant access to installed applications, system utilities, and settings. Its fuzzy search recognizes approximate names and ranks results according to recent and frequent usage. Users can create aliases for frequently launched programs and execute shell commands directly. Optional PATH integration adds command-line applications with support for popular terminal emulators. Custom search shortcuts open websites, search engines, and AI assistants with predefined queries. The launcher can also receive menu options from scripts through standard input. Additional keyboard commands reveal applications in Finder, copy file paths, and launch new application instances.

Dorso is a free, open-source macOS posture monitoring application that encourages users to sit upright while working. It detects slouching through the Mac's camera or motion sensors in compatible AirPods. Camera tracking uses Apple's Vision framework to analyze head and body positions against a calibrated baseline. AirPods tracking measures head tilt without requiring camera access. When poor posture is detected, the application progressively blurs the screen until the user corrects their position. Sensitivity and tolerance settings allow users to customize when visual reminders appear. Menu bar controls provide quick access to calibration, monitoring status, and pause options. Dorso supports multiple displays and processes tracking information locally without cloud services or user accounts.

Epigrapho es una app de notas para quien estudia la Biblia y escribe mientras lo hace: estudio personal, preparación de enseñanza, notas de seminario. En ella una referencia bíblica es un objeto, no un texto suelto. Al escribir «Juan 3:16» (o «Juan 3,16», o «John 3:16») la app la reconoce, la guarda en formato USFM (JHN.3.16) y muestra el versículo al pasar el cursor, sin salir de la nota. Después puedes encontrar todas las notas que citan ese mismo pasaje. Tus notas son tuyas. Viven en tu equipo, cifradas, y funcionan sin conexión. No hay cuentas, suscripciones ni funciones de pago.
