atomic-agent vs Observer

atomic-agent: Atomic Agent is a local-first general-purpose agent that keeps its control loop and all state on your machine. It browses the web, reads and edits files, runs approved shell commands, inspects documents, remembers context across sessions and schedules follow-ups, using local open-weight models through the team's TurboQuant llama.cpp build or cloud models. It is a developer preview for Apple Silicon Macs, Linux x64/arm64 and Windows x64.; Observer: Observer lets you build micro-agents that watch your screen, camera, microphone or clipboard and run a small local model on a loop. When the model spots a condition, JavaScript tool code sends a notification (email, Discord, Telegram, SMS, WhatsApp), records a clip or writes to memory.
