Cline vs Google Antigravity
Pricing
Cline: Free (open source), you pay for the AI API you choose
Google Antigravity: Free for individuals with weekly limits; higher limits with Google AI Pro ($19.99/mo) or Ultra (from $99.99/mo)
Description
Cline: Open-source VS Code extension that acts as an autonomous coding agent. Bring your own AI model
Google Antigravity: Google's agent-first coding platform: a desktop app for running several coding agents at once, plus an IDE, a CLI and a Python SDK
Pros
- Use any AI model (Claude, GPT-4, Gemini, local models): you control the cost
- Can browse the web, run terminal commands, create files, and edit code autonomously
- Free and open source: no subscription, just API costs
- The free plan for individuals includes unlimited Tab completions and every product feature, including scheduled tasks and the CLI
- Run several local agents in parallel and group the conversations into projects across workspaces
- Browser-in-the-loop agents can take over repetitive front-end tasks
Cons
- API costs are on you and can surprise you if you are not watching
- Setup takes more work than commercial alternatives: API keys, model selection, configuration
- Quality depends entirely on which AI model you pick
- The free quota refreshes only once a week; Google AI Pro refreshes it every five hours
- Third-party models are reserved for Google AI Ultra; the other plans run on Gemini models
- You can't add your own API key to get more usage
Details
Cline is a VS Code extension that turns your editor into an AI coding agent. Pick your AI model (Anthropic Claude, OpenAI, local models through Ollama), give it a task, and it will plan, write code, run commands, and iterate. It asks for permission before each action, so you stay in control.
The big advantage over Cursor is flexibility and transparency. You see exactly what you are paying (API costs per request), you can switch models anytime, and there is no subscription. The big disadvantage is that you have to manage all of that yourself. If you want something that just works out of the box, Cursor is easier. If you want to pick your own model and only pay for what you use, Cline is the way.
Antigravity is Google’s development platform built around agents rather than an editor with a chat panel. The main app is a command centre where you start and steer several agents at once, group conversations into projects and schedule recurring messages. There is also a full IDE, a terminal CLI and a Python SDK for building your own agents on the same harness.
The free plan for individuals is the main draw. You get the agent, unlimited Tab completions and every feature without paying, within a weekly quota, which makes it easy to try next to Cursor or Claude Code.
Limits are the catch. Google sets them by available capacity and by how much work the agent does, so the number of prompts you get varies from task to task. Google AI Pro ($19.99/month) raises the limits and refreshes them every five hours, and Pro and Ultra users can buy AI credits for usage beyond the quota. Teams can get it through Google Cloud’s Gemini Enterprise, with seats from $30 a month.
