Trying to replace a $20 Claude sub with Antigravity (5 Subagents + 5 MCP Servers)

I'm deep in the trenches for project #3. I’m testing some trending opencode and decided to go the Antigravity route instead of paying for Claude.

My setup:

• Engine: Antigravity
• Workers: 5 Subagents & 5 MCP Servers

The Verdict so far: It’s slow. Really slow. 📉
I was hoping for a smoother experience given the heavy agent setup, but the performance just isn't hitting the mark yet.
