Antigravity or Claude Code? A setup guide for small dev teams

Two tools, one practical question

As dev.to reported, a guide for small teams argues that the useful question is not which AI coding tool is smarter. It is which one fits the way your team already works. The author says the advice sticks to official documentation rather than personal benchmarks.

The two tools come from different places. Google Antigravity is described as an agent-first development platform, meaning it is built around AI agents that carry out multi-step coding tasks. It comes as an app and a command-line tool. Claude Code is Anthropic's coding agent, and it can run in a terminal, inside an editor, in a desktop app or in a browser.

Getting started and what it costs

Claude Code offers three install paths. Mac, Linux and Windows-with-Linux users can run a one-line shell script. Homebrew users have their own command, and Windows users can go through winget. After that, you open your project folder and start the tool. Most versions of it need a Claude subscription or a Claude Console account.

On price, Claude Code is part of the Pro plan at $20 a month, or $17 a month if billed yearly, and it is not on the Free plan. Antigravity's pricing page shows $0 a month for individuals, with business use handled through Google Cloud. Every plan, according to the plans page, includes the Gemini 3.8 Flash model, unlimited Tab completions (suggestions that finish your line as you type), scheduled tasks and the command-line tool, called agy.

Limits, models and one retirement date

Antigravity's usage rules are worth reading before you commit. Pro users get a quota that resets every 5 hours, up to a weekly ceiling. People on unpaid plans get a weekly reset only. Pro and Ultra subscribers can buy AI credits when they run over, but you cannot plug in your own API key.

The models page says Claude Sonnet 5.5 and Opus 5.5 are offered on Pro (but not during a trial), Ultra and Enterprise, next to Google's own Gemini models. Two older Claude versions, Sonnet 4.6 and Opus 4.6, will be removed on 2 November 2026. If your workflow depends on a specific model, note that date.

Plugins and sharing across a team

The guide calls plugins the biggest time-saver. In both tools, a plugin bundles reusable pieces: skills, MCP servers (connectors that let an agent reach outside tools and data) and hooks (small actions that fire automatically at set moments). Claude Code plugins can be installed for one user, for a whole project or just locally. The documentation warns that plugins can run hooks and MCP servers on your machine, so read what a plugin does before you install it.

An Antigravity plugin is a manifest file named plugin.json plus up to five kinds of parts: skills, MCP servers, rules, hooks and custom agents. The tool can list, validate and install plugins from the command line. It also includes an importer that reads plugins already set up for Claude Code, which lowers the cost of trying both. Google announced the plugin system in a blog post dated 29 October 2026.

For sharing, the Claude Code route is to commit a CLAUDE.md file with project rules to the repository and keep shared plugins at project level, so anyone who clones the repo gets the same setup. Claude Code can also read an AGENTS.md file. Antigravity keeps team plugins in a .agents/plugins/ folder inside the repo, with personal ones in a folder under your home directory. Its plugin rules go in a rules/AGENTS.md file.

How to choose, and a note for Jules users

The guide's recommendation is simple. If you already pay for Claude or spend your day in a terminal, begin with Claude Code. If you want a free starting point or already run on Google Cloud, try Antigravity. If you cannot decide, put your build, test and style rules in a single AGENTS.md file at the top of the repo, run one real task in each tool and compare the results.

The shared rules file is the most portable advice here. Because both tools can work with AGENTS.md, writing your conventions once means a later switch costs less.

There is also a deadline for users of Google's Jules. Its changelog says the service shuts down on 31 December 2026 and becomes read-only after 11 November, and it names Antigravity as Google's agent-first platform. If you rely on Jules, export your data before then.

One caution: the guide's authors also run a consultancy and a comparison site, and the piece points readers to both. Treat it as a useful summary of documentation, and check the current docs yourself before you pay.
