About

Agentastic.dev is a native macOS development workspace for software developers using AI coding agents. It combines an editor, terminal, browser, Git tools, and agent sessions so users can launch multiple coding agents and isolate tasks in Git worktrees or containers. Developers can inspect diffs, run code-review workflows, test applications in the built-in browser, and start work from prompts, specifications, or supported issues and team tools. The product supports a catalog of coding-agent command-line tools and allows custom terminal-based agents. Work can run locally, on SSH-accessible development machines, or in supported cloud environments. An iPhone companion lets users monitor sessions and respond when agents need input. The macOS app is free; subscriptions and API usage for third-party agents are paid to those providers.

About

Antigravity CLI is the terminal-first surface for interacting with Antigravity agents, built to let developers stay in their flow without context switching. It allows users to edit, orchestrate, and build in natural language by telling agents what they need and letting them work on getting it done. It is designed as the most lightweight way to invoke, monitor, and interact with Antigravity agents, with a snappy experience and minimal resource footprint for builders who live in the terminal. Antigravity CLI supports subagents, allowing multiple agents to work in parallel so larger tasks can be tackled faster. Users can delegate background tasks to concurrent agent sessions, type /agents to open the panel and monitor status, and use ctrl+k to approve tools instantly. It is highly configurable, with standard terminal shortcuts, adjustable permissions, themes, preferences through /config, and customizable keybindings through /keybindings.

Pros & Cons from Real Users

Pros

  • Antigravity CLI looks really strong for developers who want agentic coding without leaving the terminal. I like that it brings Antigravity’s multi-step reasoning, code editing, tool use, and persistent history into a keyboard-first workflow. The subagent idea is especially interesting. Being able to spin up multiple agents in parallel could make bigger tasks feel less painful, especially when one agent can inspect code, another can work on tests, and another can handle supporting changes. I also like that it is tied into the broader Antigravity platform. The IDE, CLI, SDK, MCP support, skills, and deeper context awareness make it feel like part of a real developer ecosystem instead of a one-off command-line chatbot.

Cons

  • I would still supervise it closely. Coding agents with terminal access can make mistakes, run the wrong command, misunderstand project context, or touch files you did not expect. Google’s own GitHub README warns that AI coding agents have risks like autonomous code execution, data exfiltration, prompt injection, and supply chain issues, so I would be careful with secrets, production systems, and unfamiliar repos.
