The short answer

AgentHydra shows Claude Code, Codex and OpenCode sessions running on your machine in one searchable list that updates live while they run [1]. It lets you type a reply into a Claude session's own desktop chat, or send one message to several sessions at once [1]. It moves a Claude chat with its history to another of your accounts [1]. It splits a task's pieces across Claude Code command line sessions on your accounts, and moves a worker to another account when one nears its limit [1]. It shows cost at API list prices by day, model, project and account [1]. Aider is a tool developers use with AI, but no facts from its own pages were provided for this comparison, so what it does is not stated here. Pick by the question you have and check the sources for each tool.

What Aider is built for

No facts from Aider's own pages were provided for this comparison, so what it is built for is not stated here.

You can type replies into Claude sessions, send one message to several, move chats between accounts and split tasks across sessions [1] [1] [1]. You can check cost by day, model, project and account, or print the same numbers as JSON from the command line [1] [1].
