Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

ATLAS·OS

Autonomous Teams · Lifecycle · Agents · Skills — Orchestration System

A multi-agent, hook-driven, model-agnostic engineering OS for the terminal. Hand it a vague idea. Get back a planned, built, tested, committed feature — with a Greek pantheon of specialist agents doing the work.

npm version License

npx atlas-os@latest

Works on macOS, Linux, and Windows through WSL2. Bring Anthropic Claude, OpenAI GPT, OpenRouter, OpenCode Zen, OpenCode Go, or run local Llama / Qwen / DeepSeek models through Ollama, LM Studio, vLLM, or llama.cpp.

Atlas·OS terminal

Install

macOS / Linux

npx atlas-os@latest

# Or install globally
npm install -g atlas-os
atlas

Atlas checks npm for newer atlas-os releases when the TUI opens. If your global install is behind, it shows a short dismissible update notice with:

npm install -g atlas-os@latest

Windows

WSL2 is recommended:

wsl --install -d Ubuntu

Then inside Ubuntu:

sudo apt update && sudo apt install -y nodejs npm
npm install -g atlas-os
atlas

Native Windows can run the core CLI, but the shell tool expects POSIX commands.

VS Code

atlas vscode-setup
# then reload VS Code

Use --dry-run to preview the settings change.

Providers

Open the TUI and use /config to add a provider key:

atlas

Environment variables also work:

export OPENROUTER_API_KEY=sk-or-...
export ANTHROPIC_API_KEY=sk-ant-...
export OPENAI_API_KEY=sk-...
export OPENCODE_ZEN_API_KEY=oc-...
export OPENCODE_GO_API_KEY=oc-...

Hosted model cost posture is configurable from /config -> Atlas power mode.

| Mode | Cost Estimate | Pros | Cons | |---|---|---|---| | Atlas Power Full | roughly 100k-250k input tokens on heavy turns before cache; cache-capable models make repeat turns cheaper | maximum Atlas context, tools, MCP, hooks, and predictable behavior | no-cache models rebill the full prefix each message | | Atlas Smart Mode | roughly 20k-80k input tokens on normal hosted turns; complex turns can still pay Full Atlas costs | cost-aware default for daily hosted work | very complex work may still need the full prompt/tool surface |

The active hosted mode is visible in the TUI top bar as ATLAS POWER in bright red or ATLAS SMART in bright green.

The model picker writes cache support beside provider-pulled models as cache yes, cache unknown, or cache no so cheaper cache-capable models are easy to spot. OpenRouter and OpenCode rows use live /models cache-pricing fields, and /models includes a search field for filtering long provider catalogs.

Saved sessions are managed from /sessions: resume, rename, start fresh, delete one, select several for deletion, or delete all with confirmation.

Local models work through Ollama, LM Studio, vLLM, or any local OpenAI-compatible /v1 server. Atlas auto-detects Ollama at http://localhost:11434/v1; use /config -> Local models to choose Lite, Hybrid, or Full Atlas mode.

ollama pull qwen2.5-coder:1.5b
ollama pull qwen2.5-coder:7b

| Mode | Requirements | Best For | Tradeoff | |---|---|---|---| | Lite | CPU ok, 4-8 GB RAM, 1.5B-7B models | quick local chat | no model-driven tools | | Hybrid | 8-12 GB VRAM or strong CPU, 7B-14B models | local coding with core dev tools | limited tool set | | Full Atlas | 24 GB+ VRAM or hosted server, 30B-70B+ models | full Atlas prompt, tools, MCP, and hooks | largest payload |

Bootstrap once:

atlas init

New launches start fresh. Use /sessions or /resume <id> to reopen old transcripts manually.

What It Does

ATLAS·OS is a multi-agent, spec-driven coding system for the terminal. You describe the goal; the orchestrator routes work across specialist agents for planning, architecture, implementation, QA, and release.

Under the hood: typed tool contracts, lifecycle hook guardrails, skills, checklists, MCP support, sessions, and provider/model routing.

Why It Is Different

| Capability | ATLAS·OS | Claude Code | OpenCode | Gemini CLI | Kilo Code | |---|---|---|---|---|---| | Provider choice | Anthropic · OpenAI · OpenRouter · OpenCode Zen/Go | Claude-focused | Provider-agnostic | Gemini-focused | Kilo router | | Multi-agent orchestration | Built-in Greek pantheon | Agent teams + subagents | Build / Plan + subagent | Subagents | Modes | | Spec-driven pipeline | Built in | Bring your own | Bring your own | Bring your own | Bring your own | | Lifecycle hooks | Typed TypeScript hooks | Hook system | Plugins / MCP | Hooks | Plugins / MCP | | MCP servers | Built in | Built in | Built in | Built in | Built in | | Terminal-first | Full-screen TUI | Terminal | Terminal | Terminal | VS Code-first | | License | MIT | Proprietary | MIT | Apache-2.0 | MIT |

Atlas's edge is the SDD pipeline, specialist agents, typed hooks/tools, MCP integration, and release workflow shipped as one terminal system.
