Fig

What is Fig?

Fig is a macOS terminal enhancement tool. Its core function overlays an autocomplete popup within your existing terminal (Terminal, iTerm2, VS Code’s built-in terminal, etc.), providing smart completion suggestions based on the command you are typing. This goes beyond simple file path completion; it offers structured completion for subcommands, parameters, and options, along with contextual information like your git branch names, SSH hostnames, and command history.

In 2023, Fig was acquired by AWS and gradually integrated into AWS’s developer tool ecosystem, with some features continuing under the name "Amazon Q CLI." Understanding this background is helpful for assessing Fig’s current status: the original standalone Fig product is no longer maintained by an independent company, but its core philosophy and some of its functionality continue to exist in new forms.

Core Features of Fig

Command Autocomplete

This is Fig’s most core feature. When you type a command in the terminal, Fig pops up a small window displaying available options and parameters for that command, with each option accompanied by a brief description.

For example, if you type git , it lists all git subcommands (commit, push, pull, branch, etc.), with a line of description next to each subcommand. After selecting git checkout , it automatically lists all your local branch names, so you don’t need to memorize them or run git branch first.

This feature is particularly useful for tools with numerous subcommands and parameters, such as Docker, npm, yarn, kubectl, and the AWS CLI. The man pages for these tools are often lengthy, and users frequently get stuck on how to write specific parameters. Fig embeds reference documentation directly into the input process.

Smart Search of Command History

Fig records your command history and intelligently recommends previously used commands based on the current input context. For instance, if you frequently use ssh user@192.168.1.xxx to connect to different machines, Fig remembers the SSH targets you’ve used. Next time you type ssh , it lists them directly.

AI Assistance (Fig AI)

Fig later added AI capabilities: describe what you want to do in natural language, and it translates it into the corresponding command. For example, if you input "list all files larger than 100MB in the current directory," it provides a command like find . -size +100M -type f.

This feature is practical for scenarios where you are unfamiliar with certain command syntaxes—you know what you want to do but don’t remember the exact parameter structure; AI fills that gap.

Non-Intrusive Workflow Integration

Fig’s design philosophy is "overlay" rather than "replacement." It doesn’t require you to switch terminals or change your operational habits; instead, it adds an extra layer of completion experience to your existing terminal. It supports common shells like zsh, bash, and fish, and is compatible with mainstream terminal applications such as iTerm2, VS Code’s built-in terminal, and Hyper.

Comparison with Other Tools

vs Warp: Warp is another terminal product that has made significant innovations in command-line experience, but it chooses to "rewrite the terminal"—building a new terminal from scratch with built-in AI command search, grouped output, collaboration, and other features. Fig and Warp take different paths: Fig adds a layer on top of your existing terminal without requiring migration to a new app; Warp replaces the terminal entirely, offering more integrated functionality but at a higher migration cost.

vs oh-my-zsh + zsh-autosuggestions: The zsh plugin ecosystem can also provide command history suggestions, but the intelligence of completion and UI experience are significantly inferior. There is no structured subcommand description or AI translation feature. Fig’s completion feels closer to an IDE experience, with a more user-friendly UI.

vs GitHub Copilot for CLI: GitHub Copilot has launched a CLI version that also supports natural language-to-command conversion, making it the most direct competitor to Fig’s AI features. The functionality is similar; the choice between them largely depends on whether you are already subscribed to GitHub Copilot.

vs Amazon Q CLI (Post-Acquisition Form of Fig): After AWS acquired Fig, its original features were gradually integrated into Amazon Q CLI. Amazon Q CLI enhances completion for AWS service-related commands and includes an AI assistant. If your work heavily involves AWS services, this newer iteration may be more worth your attention.

Who Should Use Fig?

Developers who use the command line heavily every day: Frontend, backend, DevOps—whichever you are, if you spend a large portion of your day in the terminal, Fig delivers tangible efficiency gains by eliminating the need to memorize parameters or frequently consult documentation.

Operations and DevOps Engineers: Commands like kubectl, aws, and docker have numerous parameters; Fig’s structured completion can significantly reduce the need to look up documentation.

Developers who prefer using the built-in terminal in VS Code: Fig is compatible with VS Code’s built-in terminal, so there is no need to switch to an external terminal application.

Novice Developers: For those learning the command line, Fig’s real-time descriptions serve as an excellent learning aid—it explains the meaning of each parameter, which is more natural than rote memorization of man pages.

Limitations

Fig currently primarily supports macOS; support for Windows and Linux is limited or incomplete, which is a significant constraint for non-Mac users.

Additionally, following the AWS acquisition, the roadmap for the original standalone Fig product has changed. The product’s future direction is tied to the depth of its integration with the AWS ecosystem. For users who do not use AWS, long-term maintenance should be monitored closely.

Pricing

Fig’s basic completion functionality is free to use. Some advanced features (such as AI capabilities) had usage limits during the standalone phase. After the AWS acquisition, pricing and terms of use have changed alongside product integration; refer to the current official website for specific details.

In the realm of command-line experience, Fig has made a strong start—bringing IDE-level intelligent suggestions to the terminal. Whether you use its original form or its evolved successors, its core philosophy is worth noting: the command line should not be a test of memory, but an efficient work environment with contextual awareness.
