## Butterfish Shell

Butterfish Shell is built for people who live in the terminal. Installing it via Homebrew or go install and running butterfish shell spawns a new instance of your normal bash or zsh, with the tool intercepting standard input and output. From then on, typing a command that begins with a capital letter routes it to an AI model instead of the shell — you can ask "Why didn't that work?" and the model sees your recent history and command output to answer in context. No copy-pasting between browser and terminal.

Beyond prompting, the tool offers GPT-powered autosuggestions, similar to GitHub Copilot but inside the shell, which you accept with Tab. Prompts are kept visible and editable in a YAML file rather than hidden, so you control the instructional text sent to the model. Models are configurable too: it defaults to an OpenAI model but accepts any OpenAI-compatible endpoint through a base URL flag, including local model servers.

Goal Mode is the agentic piece. Starting a command with ! hands a goal to the model, which proposes commands you confirm with Enter; starting with !! lets it execute them without confirmation. The project is honest that this mode is hit-or-miss and works best for simple, well-guided goals such as finding large files or listing Go files recursively. An accompanying Neovim plugin, butterfish.nvim, brings the same prompting style into the editor.

**Pricing & Plans:** Butterfish Shell itself is free and open source under the MIT licence. You pay only for the model usage — typically an OpenAI API key stored in a local config file, or a self-hosted OpenAI-compatible endpoint.

- **Capital-letter prompting:** Start any line with a capital letter to send it to the AI as a prompt, while normal lowercase commands behave exactly as before.
- **Shell-history context:** The model receives your recent commands and their output, so follow-up questions like 'why did that fail?' get grounded answers.
- **GPT autosuggest:** Copilot-style command suggestions appear in the shell and can be applied with Tab, informed by your recent history.
- **Goal Mode agent:** Trigger an autonomous loop with ! to have the model propose commands toward a goal, or !! to let it run them without confirmation.
- **Transparent, swappable prompts and models:** Prompt wrappers live in an editable YAML file, and the base URL flag lets you point at any OpenAI-compatible API, including local models.

**Strengths:** Removes copy-pasting between browser and terminal by giving the model direct access to shell history and output; Prompt templates are stored in an editable YAML file instead of being hidden, so you can see and change what is sent to the model; Open source under the MIT licence with installation through Homebrew or go install; Works with any OpenAI-compatible API, including locally hosted models

**Limitations:** Requires your own API key and therefore incurs separate model usage costs; Goal Mode is explicitly described as unreliable and better suited to simple, well-specified tasks; Support is limited to bash and zsh on macOS and Linux, with no Windows shell support

## Termdock

Termdock is a developer workspace built around a simple observation: modern AI coding workflows involve more than one agent CLI, more than one machine, and a lot of context switching. Termdock brings those pieces into a single connected environment. Claude Code, Codex, Gemini CLI and other command-line tools run side by side in one workspace, so you are not juggling windows or losing track of which terminal is doing what.

The differentiator is connection rather than mere co-location. Agents can hand work off to each other — one implements while another reviews — by opening terminals, sending tasks and following results. You can pair Termdock across computers and mount a shared workspace, then create terminals, run agents and read output on the remote machine while its processes and files stay put. SSH workspaces are supported as a separate connection option. A phone browser can be paired to switch terminals, type commands, send messages and use keys like Esc and Ctrl+C, which is useful when you want to respond to an agent without opening a laptop.

Termdock also treats persistence as a first-class concern. Local and peer terminals held by the broker can keep running after you close the app, and workflows, dispatch queues and schedules organize what happens next, with Git review and Workstream providing a place to inspect results. Termdock is free to download on macOS and Windows, with no Linux installer available yet. It is a bring-your-own-agents tool: you install and pay for the AI CLIs and accounts separately, and automated queues or schedules require the host machine to stay running.

**Pricing & Plans:** Free. Termdock is free to download and use on macOS (Apple silicon and Intel) and Windows x64, with installers distributed via GitHub. AI CLI subscriptions and API usage are billed separately by those providers. No Linux installer is currently offered.

- **Multiple agent CLIs in one workspace:** Run Claude Code, Codex, Gemini CLI and other command-line agents side by side in one workspace instead of juggling separate windows.
- **Agent-to-agent handoff:** Agents can open terminals, send each other tasks and follow results, so one can implement while another reviews.
- **Connected machines:** Pair two Termdock installations and mount a shared workspace so agents run where the project lives, with processes and files staying on that machine.
- **Phone control:** Switch terminals, type instructions and respond to agents from a phone browser, with no companion app required.
- **Terminal persistence:** Close the app and broker-held local and peer terminals keep running in the background, ready to reconnect when you return.
- **Workflows, queues and Git review:** Dispatch queues, schedules and workflows organize the next steps, and Git review plus Workstream give you a place to inspect results.

**Strengths:** Free to download and use on macOS and Windows; Coordinates multiple agent CLIs in a single workspace; Cross-machine pairing and phone control reduce lock-in to one desk; Terminals can persist in the background after the app closes

**Limitations:** No Linux installer is currently available; Queues, schedules and automations require the app and a running host machine; You must install and pay for your own AI CLIs and accounts separately; Terminal persistence does not survive a host shutdown or sign-out
