fast-agent vs mymir

fast-agent: fast-agent is a CLI-first framework for building and interacting with sophisticated multimodal AI agents and workflows. It offers comprehensive support for various LLM providers, structured outputs, and vision, with unique features like MCP Feature support and live streaming responses to the terminal.; mymir: Mymir replaces the cycle of agents having no memory by providing a context network and retrieval interface. It manages the full lifecycle from brainstorming to execution, allowing agents to walk into every session knowing exactly what to do next. Built as a Claude Code plugin, it automatically provides stage-appropriate context and tracks progress.
