Runs on: Windows WSL2 macOS Linux Docker

1 The framework
openclaw
openclaw/openclawThe most-starred project in the atlas, and it puts Windows in the same sentence as macOS and Linux rather than in a footnote. Three source lists carry it.
Open-source AI agent framework that turns LLMs into persistent, proactive personal AI agents with multi-channel messaging (Signal, Telegram, Discord, WhatsApp), cron scheduling, memory systems, MCP integration, skill plugins, sub-agent spawning, and browser automation
npm install -g openclaw@latest --allow-scripts=openclaw -
2 The harness
Pi
earendil-works/piA deliberately small terminal harness built around skills loaded on demand. Small is what makes it portable: there is less of it to be Unix-shaped.
Minimal terminal coding harness built around "lazy skills": each capability keeps only a one-line description in active context, loading full instructions and tool schemas only when invoked. Keeps the system prompt under 1,000 tokens versus 7,000–10,000 for typical agents, making it a concrete reference for context-minimal harness design
npm install -g --ignore-scripts @earendil-works/pi-coding-agent -
3 The coding agent
Continue
continuedev/continueShips as an editor extension, which is why it works on Windows without a WSL detour -- the editor has already solved that problem.
Continue is an open-source autopilot plugin for VS Code and JetBrains, enhancing coding with LLMs through features like task and tab autocomplete, natural language edits, file generation, and customization options, available under the Apache 2.0 license github | website

4 The model runner
Ollama
ollama/ollamaA native Windows build, a one-line pull, and no Python environment to get wrong. If you want a local model on Windows this is the shortest path to one.
Ollama is a tool for running large language models locally, offering easy setup for macOS, Windows, Linux, and Docker, along with a library of models and quickstart guides for customization and integration github | github profile

5 The inference engine
llama.cpp
ggml-org/llama.cppThe C++ layer under most of local AI, with first-class Windows builds and no runtime to install. Worth knowing directly once the layer above it surprises you.
C/C++ inference. CPU, GPU, Apple Silicon. Foundation of local AI

6 The context budget
headroom
headroomlabs-ai/headroomCompresses tool output, logs and files before they reach the window. Windows and Docker support are both stated, and it sits in front of whatever agent you chose.
Compresses tool outputs, logs, files, and RAG chunks before they enter the context window, cutting active tokens by 60–95% without changing answers. Ships as a library, proxy, and MCP server — the right drop-in layer for any harness where bulky tool returns are the primary context pressure source

7 The sandbox
ironclaw
nearai/ironclawTreats agent execution as a privacy and isolation problem rather than a convenience one. Two source lists agree, and Windows support is documented rather than assumed.
NEAR AI's open-source agent OS that treats agent execution as a privacy-first harness problem: untrusted tools run in WASM sandboxes with capability-based permissions, credentials are injected at the host boundary with leak detection, and prompt-injection filtering plus endpoint allowlisting constrain agent behavior. The combination of local encrypted storage, hybrid-search memory, MCP server supp

The whole set, in one paste
Every install command above, in the order they are listed. Read them before you run them — they are other people's one-liners, and 3 of them pipe a download straight into a shell.
