Caspian

Caspian is one agent that manages all your AI coding agents: it runs Claude Code, Codex, Gemini, Cursor and Grok in the background, routes each task to the cheapest or strongest model depending on difficulty, and keeps one shared memory file (.caspian/context.md) so context survives across tools. It ships as both a CLI (npm install -g @caspianmd/caspian) and a desktop app, free for Windows, macOS and Linux, requiring Node.js 20.18+.

The pitch resonates with anyone who vibe-builds: the author's own Hacker News post opens "For someone who vibe builds almost all the time…" and describes building Caspian to manage the chaos of running several agents at once. Features include prompt refinement before a task runs, a pre-flight cost estimate for every run, usage analytics with live quota bars for each subscription, and email notifications when agents finish.

Why it exists

The vibe-coding workflow has a coordination problem: you pay for multiple AI subscriptions, each with its own quota, memory and CLI quirks, and you context-switch between them by hand. Caspian's answer is a single session layer on top: tell it what to do, it picks the right tool and model, shows you what it will cost before it starts, and writes a session brief you can review before anything is built.

Built for the multi-agent reality

The official screenshots show the real thing — a CLI dashboard with per-tool quota bars (Claude Code, OpenAI Codex CLI, Gemini CLI, Grok) and a desktop workbench that drafts project briefs from your agent sessions, listing what was asked, what was decided, and what files changed. It is a product made by and for people who build with AI agents all day.
