I wanted an in-app browser and custom API keys inside Google Antigravity, so I built BetterGravity (Open Source). Here's how it works:

A developer created BetterGravity, an open-source project, to add an in-app browser and custom API keys to Google Antigravity. This new tool allows users to "Bring Your Own Key" (BYOK), enabling them to utilize their personal Gemini API keys and stream raw thinking tokens. The developer is seeking feedback and feature suggestions from other Antigravity users.
