## 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

## Whop CLI

Whop CLI packages the full Whop API into one installable binary. You install it with a single shell command and then work with Whop resources directly from a terminal session, covering the building blocks of a digital business such as products, pricing plans, payments, advertising campaigns, apps, and business analytics. The intent is to remove repeated dashboard clicking for anyone running storefronts, memberships, or communities on Whop.

The tool is explicitly positioned for three audiences: creators who like to script, developers who automate recurring operations, and AI coding agents that need a machine-friendly surface. The documentation lives at docs.whop.com under the developer CLI section, and the site even provides a ready-made prompt you can hand to an agent such as Claude, Cursor, or Codex so it can install and start driving Whop on your behalf.

Because it is a thin, scriptable layer over the public API, it fits naturally into existing developer workflows, whether that means cron jobs that adjust pricing, scripts that pull revenue reports, or agent-driven app scaffolding. No pricing tiers are published on the CLI site itself; access follows from your Whop account and API credentials.

**Pricing & Plans:** No standalone pricing published; the CLI is distributed free and works with your existing Whop account and API credentials.

- **Single-binary install:** Install with one curl command and manage every Whop API resource without leaving the terminal.
- **Full resource coverage:** Work with products, pricing, payments, advertising, apps, and business analytics through consistent commands.
- **Agent-ready prompt:** Copy a prepared prompt and hand it to an AI coding agent like Claude, Cursor, or Codex to install and operate the CLI for you.
- **Scriptable automation:** Compose commands into scripts and scheduled jobs for recurring business operations.
- **Official documentation:** Reference material is maintained in the Whop developer docs under the CLI section.

**Strengths:** Official CLI from Whop with full API coverage; One-command install with no configuration overhead; Designed for scripting, automation, and AI agents; Well-documented in the official developer docs

**Limitations:** Requires comfort with command-line workflows and Whop API credentials; No visual interface, so it is not aimed at non-technical operators
