Pared Apple Intelligence Cleaner
A tool that selectively removes unwanted Apple Intelligence models on macOS without disabling SIP, via a native app, CLI, nix-darwin, and Home Manager. It also underpins RemoveMacAI, which credits it for the hard reverse-engineering work.
Plannotator Terminal Markdown Annotations
A terminal Markdown annotator for selecting text and leaving comment, looks-good, or delete marks, then handing the numbered review to a coding agent. A single static Rust binary aimed at the current wave of agent-assisted code review workflows.
Tsuzuri Terminal Notebook
A block-based notebook for the terminal that stores notes as plain Markdown and offers Vim-style editing, live preview, boards, calendars, and 96 themes. A single-binary install for macOS, Linux, and Windows makes it an unusually full-featured TUI note-taking option.
Dopbase DevOps Secrets Manager
An open-source, self-hosted secrets manager packaged as a single file containing the server, Admin UI, REST API, and CLI, storing data in SQLite. A practical, still-maintained option for small DevOps teams wanting to keep secrets on their own infrastructure.
RemoveMacAI macOS Debloater
A native macOS app and CLI to disable Apple Intelligence, delete its models, and silence analytics, ads, pop-ups, and background updaters, with every change previewable and reversible. It builds on pared's reverse-engineering and drew press coverage, though its star growth looks inflated.
Terrahour Terminal World Clock
A terminal world clock that renders a braille-dot day/night world map plus a 24-hour per-city timeline for planning meetings across zones. It includes DST handling and time scrubbing, and is a polished, fresh single-tool TUI.
PuppetLoom
A Windows desktop app, deterministic CLI, and project format that turns layered PSD character art into rigged, animated desktop puppets, with agents driving revisions through a public CLI. It builds on the See-Through layer-decomposition research and never fabricates missing poses.
Tincan CLI
A serverless peer-to-peer voice and text chat CLI for terminals. Notable for using Iroh to create rooms without servers, VPNs, or accounts, making it useful for remote developers.
Issue Graph
A CLI that traces linked GitHub issues and pull requests to find related work before starting. Notable for helping with triage and agent workflows, backed by Vercel Labs.
Suiko Japanese Diagnostics
A Rust CLI for deterministic diagnostics of Japanese text naturalness and readability. Notable for its reproducible, local-only analysis with embedded dictionaries, useful for non-native writers.
Runyte Workspace
A modal text editor combined with terminals, files, and Git in a single terminal workspace. Notable as an ambitious TUI aiming to unify development tools in one persistent session.
Bast SSH Manager
A terminal tool for browsing SSH hosts, syncing cloud VMs, managing keys, and connecting via SFTP. Notable as a fast, fresh alternative to Termius for cloud-heavy developers.
k10s Kubernetes TUI
A clickable Kubernetes TUI with instant search, logs, exec, port-forwarding, themes, and context-aware AI. Notable as a practical, feature-rich alternative to k9s, distributed as a single Go binary.
GhostHub Terminal
A Ghostty-native terminal multiplexer for local and remote tmux, Herdr, and Zellij sessions with Git worktree management. Notable for integrating multiple multiplexers across SSH hosts in one interface.
Barrage Load Tester
Barrage is a load testing tool that drives concurrent HTTP, database, and Redis load on a single clock, correlating latencies to identify bottlenecks. It is notable for its shareable HTML report that flags exactly which layer and time bucket spiked.
RestoreDrill Backup Validator
restoredrill proves PostgreSQL and MySQL backups actually restore by fetching the latest backup, restoring it into a throwaway container, and running defined checks. It is notable for its high practical value, addressing the common gap of untested backups with a JSON report.
Ritridata Disk Inspection
Ritridata is a read-only Rust toolkit for MBR/GPT partition inspection, public file signature definitions, and synthetic disk image generation. It is notable as a specialized, offline DFIR utility for answering partition structure and file format questions.
TSK Task Board
tsk is a terminal-based shared task board offering a TUI for humans and a CLI for agents, serving as a Linear alternative. It is notable for its dev-agent workflow integration, keeping tasks, work in progress, and waiting items visible.
Jevgrep Code Search
Jevgrep is a CLI for coding agents that finds relevant code by asking repository questions, returning files, reading leads, and source excerpts. It is notable for completing 8 of 10 SWE-bench tasks at roughly 30% lower cost than its baseline.
Harbor GitHub Workspace
Harbor is a focused desktop workspace for GitHub notifications, issues, pull requests, Actions, and repository discovery, with an optional repository-aware agent. It is notable as an early Tauri-based client for power users, now renamed Repolane.
Jgrep Meaning Filter
jgrep filters lines by meaning using TypeSafe's Jev decision model, treating each line as a yes/no question against a description. It is notable for providing fast semantic grep at roughly 200 ms and a thousandth of a cent per line.

Social Platform SDK
Typed TypeScript SDK for integrating with social platforms like Bluesky, Instagram, and X, with direct adapters or managed backends. Provides capability checks, explicit outcomes, and deterministic mock testing.
Coding Agent Control
Control plane for coding agents like Claude Code and Codex, running locally by default with optional multi-device sync. Notable for its local-first design requiring no account or network connection.
DBDelve Database Client
Cross-platform database client for Postgres, MySQL, SQLite, Snowflake, and SQL Server, written in Rust with GPUI. Aims to provide smooth performance and low memory usage on large datasets, though still early.

Open-source platform for coordinating multiple AI agents and teams across Slack, Telegram, Discord, GitHub, and other tools. Alternative to Claude Tag, enabling agents to collaborate in shared conversations.
Selective Remote Client
Native macOS client for SSH, RDP, SFTP, and port forwarding that keeps connections, files, and commands in one place. Fills a gap in native Mac remote access tools, though still maturing.
Birdview AI Mapper
Birdview is a skill for AI coding agents that maps architecture and constraints into one reviewable view before changes; the agent shows the map and plan, waits for confirmation, then implements and records verification.
Grok Keysmith
Preview-first installer for Grok Build that writes custom instructions only after showing a plan and receiving confirmation, then supports verification and layered uninstall. It does not modify Grok or read account credentials.
