Google Antigravity vs Lovable
Pricing
Google Antigravity: Free for individuals with weekly limits; higher limits with Google AI Pro ($19.99/mo) or Ultra (from $99.99/mo)
Lovable: Free tier, Starter from $20/mo
Description
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
Lovable: Describe your app idea, get a working React + Supabase app you can actually edit and deploy
Pros
- 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
- Generates full-stack apps (React frontend + Supabase backend) from a description
- Built-in Supabase integration handles auth, database, and storage
- Non-technical founders can build real, functional products
Cons
- 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
- You get what the AI decides: limited control over code architecture and patterns
- Complex business logic still needs a developer to implement properly
- Tied to React + Supabase stack whether that is the right choice or not
Details
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.
Lovable (formerly GPT Engineer) is for founders who have an idea and want a working app, not a wireframe or a mockup. You describe what you want, and it generates a full-stack React app with a Supabase backend: auth, database, the works. You can then edit the code or keep iterating with prompts.
This is not a toy. People have shipped real MVPs with it. But know the limits: the generated code follows patterns the AI knows, which may not be the best patterns for your specific use case. If your app is a straightforward CRUD tool or marketplace, Lovable can get you 80% there. If you need complex real-time features or unusual architecture, you will hit walls.
