Managing multiple Google accounts in Antigravity and keeping track of where my tokens were going became a real pain point — so I built an extension to solve it.
AG Multi-Account Switchboard is a sidebar panel that gives you full visibility into your accounts, context window, and token usage — all without leaving the IDE.
What it does
🔄 Multi-Account Switching
- Add multiple Google accounts, switch between them with one click
- Live usage tracking with color-coded progress bars and reset timers
- Pin your most-used model to always see it at a glance
- Auto-detects external account switches within ~1 second
🧠 Context Window Intelligence
- See exactly what's eating your context window — MCP tools, rules, skills, workflows, chat messages
- Donut chart + stacked bar showing token distribution across categories
- Full editor panel with collapsible tree view, step preview, and filters
- 🔥 badges flag the heaviest token consumers
- Export your entire conversation as Markdown
📊 Usage Analytics
- Track token usage and estimated costs across every conversation you've ever had
- GitHub-style activity heatmap, model distribution charts, weekly patterns
- Full dashboard with 9 KPI cards, monthly cost breakdown, and top conversations by cost
- Configurable model pricing (per 1M tokens) for accurate cost estimation
- All data is local — cached to disk for instant load

Built this entirely with the help of Antigravity's agentic coding — from architecture to the dual Language Server discovery system. Would love to hear feedback or feature requests!
Edit:
I built this extension and it has a cost estimation feature based on public API rates. So I can actually see what's going on behind the curtain.
My usage dashboard this month shows $2,694 in estimated API costs. I pay $249/month for Ultra. Google is eating roughly 11x what I pay them. If you're on the $19 standard plan, the math is even crazier — we're talking 50x+ subsidy per user.
None of this is sustainable and everyone in the industry knows it. Anthropic is burning through $6B this year and doesn't expect to break even until 2028. OpenAI lost $8-9B in 2025 alone — profitability target is 2029 at the earliest. Google just announced $175-185B in AI infrastructure spending for 2026, almost double what they spent last year.
Remember when AG first launched? Unlimited usage, super generous usages, cheap plans. That wasn't charity — that was customer acquisition. They wanted you hooked on the workflow before the prices went up. Classic platform play. Now that developers are locked in and switching costs are real, the corrections are coming. Tighter rate limist, higher prices — this was always the plan.
Even after cutting token prices aggressively over the past year, they're still hemorrhaging money. The compute costs, the GPU clusters, the power bills — none of it adds up at current subscription prices. We're years away from any of these companies making money on AI, and that's assuming chip efficiency improves significantly.
So blaming a sidebar extension for "ruining it for everyone" is missing the point entirely. Prices are going up because the original pricing was a loss leader, and physics doesn't care about your feelings. My extension just reads local files and calls the same sign-in flow that's already built into the IDE.
