It’s not worth buying the Ultra plan; it’s bloated with things that aren’t used in antigravity and don’t provide enough capacity to develop anything with Claude.
The quotas that still have some capacity are the Gemini quotas, which don’t know how to make a multipage HTML website.
It’s more worthwhile to spend $200 paying directly for the Anthropic API than the Ultra plan.
When it started, it was worthwhile, correct, until there were fine adjustments to the quotas. But adjustments that now penalize the user who actually uses it for work aren’t a tool. It’s just a mechanism for delaying your time by 5 hours.
