About

Herdr is a terminal-based runtime and multiplexer for developers who run AI coding agents, shells, tests, and other command-line tools. It organizes work into workspaces, tabs, and panes managed by a background server, so processes can keep running when a client disconnects. Users can reattach locally or connect to Herdr on other machines over SSH. The software detects supported coding agents and displays whether they are working, blocked, idle, or done; integrations can preserve native agent sessions after a server restart. Its CLI and local socket API let scripts and agents inspect sessions, manage panes, start or prompt agents, and wait for state changes. Developers can configure keybindings and themes and extend workflows with local executable plugins. Herdr is installed on macOS, Linux, or Windows and is released under the Apache 2.0 license.

About

(Koi Editor is now Peeknext) Peeknext is a professional text and code editor for macOS, built around three principles: fast, local, and scriptable. Designed for low-latency editing and large-file performance, Peeknext includes multi-cursor editing, synchronized views, project-wide search, context-aware autocomplete, syntax highlighting for 30+ languages, code folding, file outlines, customizable themes and keybindings, and extensive editing commands. Peeknext requires no account, includes no telemetry, and works entirely offline. Configuration and keybindings use plain text files, while custom editor commands can be written in Python. Optional AI features connect to local models through Ollama for code completion and inline assistance. Built for Apple Silicon Macs, Peeknext combines a high-performance editing core with native macOS integration.
