DAC is a dashboard-as-code CLI and framework for building interactive dashboards from YAML and TSX, with a built-in semantic layer and an AI agent workflow for updating dashboards.

Cockpit is a web UI for Claude Code that lets you run and manage sessions from a browser instead of the terminal. It supports multiple concurrent sessions, transcript history, diff and file views, PR review workflows, scheduled runs, and settings for agents, skills, hooks, MCP servers, and CLAUDE.md.

Open-source CLI that runs Codex, Claude, and Gemini in parallel on the same prompt, then synthesizes one answer and surfaces disagreements.

AutoRound is an open-source quantization toolkit for LLMs and VLMs, focused on high-accuracy low-bit inference across CPU, XPU, CUDA, and multiple deployment backends.

OpenAI’s SDK docs for programmatically controlling local Codex agents, with coverage of setup, core concepts, tools, orchestration, evaluation, and deployment paths.

Open-source C++ and CUDA LLM inference engine inspired by vLLM, with a teaching-focused course that walks through model serving, batching, KV cache, and attention kernels.

OpenHive is a shared knowledge base for AI agents to search and post problem-solution pairs. The page shows multiple integration paths, including Agent Skills, MCP, REST API, and discovery endpoints.

An interactive guide for choosing local AI hardware and matching open-weights LLMs to specific builds. It offers budget-based build recommendations, a hardware picker, model-to-hardware compatibility, and a state-of-the-local-AI snapshot.

CostHawk is a team analytics platform for tracking AI adoption, usage, and spend across tools like Claude Code, Codex, Cursor, and provider APIs. It includes role-based views for engineering, product, finance, and leadership, plus budget alerts, exports, admin API access, and MCP-based setup.

Open-source SDK for governing AI agent tool calls before side effects happen, with policy enforcement, approval flows, audit logs, and local execution.

LLMCap is a proxy for LLM API calls that hard-stops requests when a dollar cap is reached, with support for major providers and companion tools for VS Code, CLI, and Windows.

TokenBBQ is an open-source dashboard and CLI that tracks token usage and estimated costs across Claude Code, Codex, Gemini, OpenCode, Amp, and Pi-Agent from local files on your machine.
