Atomic vs Pan-Agent

Atomic has no write-up on Specifiction yet; its figures are above.

Pan-Agent is a free, MIT-licensed, open-source AI assistant that runs on the user’s own machine. It can take screenshots, interpret screens, type, click, manage windows, run commands, and browse the web. The project lists more than 20 built-in tools, including terminal, filesystem, browser, web search, keyboard, mouse, vision, memory, and cron. It connects to OpenAI-compatible providers such as OpenAI, Anthropic, OpenRouter, Groq, Ollama, LM Studio, vLLM, and llama.cpp. Cron expressions can schedule agent runs, while separate profiles isolate API keys, model settings, persona, memory, and skills. Telegram, Discord, and Slack bots work without a public URL. A headless local HTTP API runs on localhost:8642 and has a documented set of 50 endpoints. Its 103-pattern approval system classifies commands and blocks catastrophic actions by default. Sessions use SQLite, and updates verify Ed25519 signatures. The project says it has no telemetry. Important limits include an unauthenticated API, Linux control requiring X11 or XWayland, unsigned Windows installers, and a macOS app that is not notarized.
