| Attribute | Claude Code | Google Antigravity | Vapi |
|---|---|---|---|
| Plans | ProOur pick $20/mo, or $17/mo billed yearly Trying Claude Code and light daily use. | IndividualOur pick Free Trying agent-based coding without paying. | Pay as you goOur pick $0.05/min hosting, plus provider costs Developers building and testing. |
Team From $20/seat/mo billed yearly, or $25 monthly Businesses with 2 to 150 people who want central billing. | Google AI Pro $19.99/mo People who already have or want the Google AI Pro bundle. | Core $29/mo plus usage Builders and early teams going live. | |
Enterprise $20/seat/mo billed yearly, 20-seat minimum Larger companies with compliance needs. | Google AI Ultra From $99.99/mo Developers who want Antigravity as a daily driver. | Pro 10% of hosting fee, $999/mo minimum Teams running voice agents in production at scale. | |
Max From $100/mo Anyone running Claude Code for hours a day. | Business (via Google Cloud) From $30/seat/mo Companies already on Google Cloud. | Premier Custom Large organisations. | |
API (pay as you go) Usage based Teams who want to pay only for what they use. | |||
| Which plan to pick | Start on Pro. It is enough to build a small site or tool in evenings and weekends. If you hit the limit most days, Max 5x is the next step; it costs five times as much but usually works out cheaper than paying for the API directly. Max also lets you spend up to half your weekly limit on Fable, which Pro only gets through paid credits. | Start on the free Individual tier; it is the whole point. If you hit the weekly limits and you also use Gemini for other things, Google AI Pro at $19.99 is a sensible step. Ultra only makes sense for full-time developers. | Build on pay as you go, then add Core when you go live and want email support. HIPAA compliance is a separate $2,000-a-month add-on, so check that early if you work in healthcare. |
