## 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

## Orca

Orca positions itself as an "agent IDE" rather than a classic code editor. The core idea is that IDEs were designed around a single human editor, while AI-era workflows revolve around many agents working at the same time. Orca therefore organises work into projects, workspaces and worktrees: each task gets an isolated environment, and any agent CLI can be pointed at it.

The app bundles the pieces developers normally stitch together by hand — chat or terminal interfaces, a built-in browser with a design-inspection mode, split panes for diffs and files, a notes/editor surface and Git integration. A command-line interface mirrors the GUI, so agents themselves can create worktrees, start workers, drive the browser and schedule automations through Orca's own CLI.

Orca is cross-platform (macOS, Windows, Linux) with companion iOS and Android apps that notify you when an agent needs input so you can reply from your phone. It is distributed as free open-source software, and the project also offers a documented enterprise track and a plugin system for extending the environment.

**Pricing & Plans:** Orca is free and open source; the download and core product require no payment. A separate Enterprise offering is available, priced by contacting the team. The site does not publish a public price list for enterprise plans.

- **Parallel worktrees:** Each agent gets its own isolated Git worktree, so multiple agents can edit, test and build concurrently without conflicts.
- **Bring your own agent CLI:** Works with Claude Code, Codex, Gemini, Cursor CLI, OpenCode, Copilot, Cline and many other command-line agents using subscriptions you already have.
- **Integrated browser and design mode:** A built-in browser lets you click any element to copy its HTML, styles and selector, or screenshot a page and drop that context straight into an agent prompt.
- **Terminal, diffs and split panes:** Review AI output, run commands and arrange terminals, browsers, files and diffs in panes shaped to the task at hand.
- **CLI, plugins and mobile companion:** Orca's own CLI lets agents automate worktrees and workers, a plugin system extends the app, and iOS/Android apps keep you in the loop remotely.

**Strengths:** Free and open source, with no licence cost for the core product; Genuinely parallel workflow thanks to per-task Git worktrees; Vendor-neutral: works with many agent CLIs instead of locking you to one; Cross-platform with iOS and Android companion apps and an extensible plugin system

**Limitations:** Not a traditional IDE, so developers wanting a full editor experience may need a second tool; Newer product with fast-moving releases, which can mean occasional rough edges; Enterprise pricing is only available on request, so costs are not transparent up front
