OpenCode is a tool in the same AI coding session manager category, but no facts are given here about what its own pages say it does. AgentHydra, made by the team that publishes this site, shows Claude Code, Codex and OpenCode sessions in one searchable list and is free and open source [^2] [^2]. | Option | What its sources say it does | Cost | Account or install | |---|---|---|---| | opcode (formerly Claudia) | A GUI app and Toolkit for Claude Code that lets you create custom agents, manage interactive sessions and run secure background agents [^1] [^1] | not published [^1] | Windows 10/11, macOS 11+, or Ubuntu 20.04+; 4GB RAM minimum, 8GB recommended; 1GB free storage; release executables will be published soon [^1] [^1] [^1] [^1] | | OpenCode | No facts given here about what its own pages say it does | not published | not published in the facts | | AgentHydra | Shows Claude Code, Codex and OpenCode sessions in one searchable list, updated live [^2]; lets you reply to Claude sessions and send one message to several [^2]; shows cost at API list prices by day, model, project and account [^2] | free, no account or subscription [^2] | On Windows, install with a one-line PowerShell script, download a build from GitHub Releases, or run from source with Bun; the tray app needs Windows, macOS and Linux builds exist but have not been verified [^2] [^2] | ## The short answer opcode describes itself as a GUI app and Toolkit for Claude Code [^1]. OpenCode sits in the same AI coding session manager category, but the facts given here do not describe what its own pages say it does, so nothing further can be stated about it. 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, updated live while they run [^2]. It is free with no account or subscription [^2]. Pick by the need you have: managing Claude Code sessions with a graphical app points to opcode, and seeing sessions from several tools in one list points to AgentHydra. ## What opcode (formerly Claudia), OpenCode is built for opcode describes itself as a GUI app and Toolkit for Claude Code [^1]. It requires Windows 10/11, macOS 11+, or Linux running Ubuntu 20.04 or later [^1]. The facts given here do not include any description of what OpenCode does, so nothing is stated about it beyond its name in the AI coding session manager category. ## What AgentHydra is built for AgentHydra is made by the team that publishes this site. It shows Claude Code, Codex and OpenCode sessions on your machine in one searchable list, updated live while they run [^2]. It lets you type a reply into a Claude session's own desktop chat, or send one message to several sessions [^2]. It moves a Claude chat, history included, to another of your accounts [^2]. It splits a task's pieces across Claude Code CLI sessions on your accounts, and moves a worker to another account when one nears its limit [^2]. It shows cost at API list prices by day, model, project and account [^2]. It pairs each failed shell command with the command that fixed it, and can copy those pairs out as a rules file for your agents [^2]. It lists each Claude and Codex account with its plan and 5-hour and weekly quota, and can open, focus, quit, create and delete Claude Desktop instances [^2]. It exposes its features as MCP tools, including whoami and usage checks so an agent knows which account it is on and how much quota is left [^2]. It packs a task and its repository into a Markdown file, leaving out common secret files, then copies a prompt and opens ChatGPT for you to send yourself [^2]. It prints the same cost numbers as JSON from the command line [^2]. ## Pricing and fees AgentHydra is free, with no account or subscription [^2]. The facts given here do not state a dollar price for opcode, so it is not published here [^1]. The facts given here do not state a price for OpenCode, so it is not published here either. AgentHydra is open source under the MIT License [^2]. If you need the cost of opcode or OpenCode for your own use, check their own pages, since the facts here do not state one for either tool. ## Setting it up and daily use opcode requires Windows 10/11, macOS 11+, or Linux running Ubuntu 20.04 or later [^1]. Its release executables will be published soon, so the facts here describe planned availability rather than a download you can get today [^1]. AgentHydra installs on Windows with a one-line PowerShell script, or you can download a build from GitHub Releases or run from source with Bun [^2]. The tray app needs Windows; macOS and Linux builds exist but have not been verified [^2]. The facts here say nothing about installing or setting up OpenCode, so check its own pages for anything further. ## Things to check before you choose Ask what you need the tool to do with your coding sessions. opcode describes itself as a GUI app and Toolkit for Claude Code [^1], while AgentHydra shows sessions from Claude Code, Codex and OpenCode in one list [^2]. Ask which operating system you use. opcode supports Windows 10/11, macOS 11+ and Ubuntu 20.04+ [^1], and AgentHydra's tray app needs Windows, with macOS and Linux builds that exist but have not been verified [^2]. Check whether you need to run the tool today: opcode's release executables will be published soon [^1], and AgentHydra can be installed on Windows with a one-line PowerShell script [^2]. Ask whether local data matters to you. The facts here say nothing about how OpenCode stores data, so check its own pages. ## How to choose Match the need to the tool whose source says it meets the need. If you need a GUI app and Toolkit for Claude Code, opcode describes itself as one [^1]. If you need to see Claude Code, Codex and OpenCode sessions in one searchable list that updates live, AgentHydra does that [^2]. If you need to send one message to several Claude sessions at once, AgentHydra lets you do that [^2]. If you need to see cost by day, model, project and account, AgentHydra shows cost at API list prices [^2]. If local data matters to you, check how each tool stores it on its own pages. If you need a free, open source tool, AgentHydra is free under the MIT License [^2] [^2]. The facts here do not describe what OpenCode does, so check its own pages to see whether it meets a need the others do not. ## Frequently asked questions ### Is AgentHydra free to use?
