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
- Generates complete working apps from natural language descriptions
- Built-in database, auth, hosting, and 20+ integrations (Stripe, Google APIs, etc.)
- No deployment step: apps are live immediately
- 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
- Free tier is extremely limited (5 messages/day, 25/month)
- Acquired by Wix in 2025. Product direction may shift toward Wix's ecosystem
- Less control over code and architecture than hand-built solutions
- 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
Base44 takes a different approach from most AI app builders: instead of writing code you can see, it generates complete applications through a chat interface. Describe what you need (“build me a task management app with user auth and Stripe billing”), and it creates the database, UI, backend logic, and authentication. Apps are live immediately with built-in hosting.
Wix acquired Base44 in 2025 for around $80 million, so expect the product to evolve toward the Wix ecosystem over time. The free tier is tight (5 messages per day), but enough to test whether the approach works for your use case. Best for internal tools, simple SaaS MVPs, and founders who want something working today rather than something architecturally perfect.
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.
