fast-agent vs VexJoy Agent
Bottom line
fast-agent is a toolkit for building, running and evaluating agents; VexJoy is a prebuilt assistant that routes each request to a specialist.
Who it's for — Pick fast-agent if you want to define agents and workflows yourself, run them from a CLI with shell access, and connect MCP, ACP or A2A servers. Pick VexJoy if you want to type /do and let a router choose from 43 agents, 62 skills and 78 hooks.
Who it's NOT for — Skip fast-agent if you want a daily driver without writing config. Skip VexJoy if you cannot run its router dependency or need to stay inside one host.
One verifiable fact — 3,959 stars vs 446, both checked Nov 6, 2026 — nearly nine times apart.
Try / Skip — Try fast-agent for custom pipelines and evals; try VexJoy for ready-made domain help. Skip both if a plain chat window is enough.
