## 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

## CtrlOps

CtrlOps is a desktop application built for engineers and small teams who look after Linux servers and are tired of juggling SSH tabs, sticky notes of IPs, and half-remembered bash commands. It connects directly over SSH to every host you own, regardless of whether it runs on AWS, Google Cloud, Azure, DigitalOcean, or a plain VPS, and gathers them into a single fleet view where each server has an alias instead of an IP address.

The headline feature is the AI terminal: you describe what you want in everyday language, CtrlOps proposes the shell commands, and nothing executes until you review and approve it. Around that sit the tasks that normally eat an afternoon, such as browsing and moving remote files, tailing and searching logs, running 25 security audits with a hardening score and PDF report, viewing live CPU, memory, disk, and network metrics, and shipping a GitHub repository to production in one form (env vars, domain, SSL, Nginx, and PM2 handled for you). Scheduled folder backups to S3, cron jobs, port forwarding, and an access scan that shows who can log in and who has sudo round out the toolset.

The architectural choice that defines the product is that everything is local: SSH keys, host addresses, and secrets stay on your device, and a direct SSH connection replaces any vendor cloud bridge. That keeps latency low and removes a third party from your infrastructure path, but it also means there is no browser version and no team-shared web dashboard. Since 2024 the team has grown a public library of free generators and scanners alongside the app itself.

**Pricing & Plans:** Free trial for one month with no credit card required, after which it moves to paid plans; a large set of browser-based generators and scanners (SSH config, cron, chmod, CIDR, VPS security scanner) is free. Confirm current tiers on the official pricing page.

- **AI terminal with approval gating:** Describe the outcome in plain English and CtrlOps drafts the shell command; nothing runs until you review and approve it.
- **Unified multi-server management:** Keep your whole fleet in one window with named aliases, per-server SSH keys, and an access scan showing who can log in and who holds sudo.
- **One-click deployment from GitHub:** Fill a single form with your repo, environment variables, and domain, and CtrlOps provisions the app with Nginx, SSL, and PM2.
- **Live monitoring and log tooling:** Watch CPU, memory, disk, and network in real time, and find, search, or tail logs across hosts without hunting for paths.
- **Security audits and hardening report:** Run 25 SSH-based audits against a server, get a hardening score plus a PDF report, and apply fix commands with explicit approval.

**Strengths:** Runs entirely on your machine, so SSH keys, IPs, and secrets are never uploaded to a vendor cloud; Connects to any provider over plain SSH with no agent installed on the servers; The AI terminal keeps a human in the loop, which makes it far less scary to use against production; Bundles deployment, monitoring, audits, backups, and file handling that would otherwise need several separate tools

**Limitations:** Desktop-only: there is no browser interface or shared cloud dashboard for a distributed team; Real value appears once you manage several servers; a single hobby box may not justify a subscription; Deployment flow is opinionated toward PM2, Nginx, and SSL, which can clash with existing pipelines
