The short answer
Aider is a command-line tool for pair-programming with an AI model in a terminal session. opcode (formerly Claudia) is a graphical app and toolkit for Claude Code. [1] Aider does for a developer what its own sources say it does, and the facts given here do not add detail beyond that. opcode's own page says it is built for Claude Code specifically. [1] AgentHydra is made by the team that publishes this site, and it shows Claude Code, Codex and OpenCode sessions on your machine in one searchable list that updates live while they run. [2] Pick by the question you have: the need to create custom agents and manage Claude Code sessions points to opcode, and the need to see sessions across Claude Code, Codex and OpenCode in one list points to AgentHydra.
