An open-source AI agent for your Claude, GPT, dbt, warehouse, and cloud bills. Connect 15+ platforms in minutes — self-host in 10, or use our cloud.
15+ connectors across your entire data stack
Warehouses, pipelines, BI, AI models, CI/CD — if it has a bill, costly tracks it.
costly connects your cost data across platforms and uses AI to surface what matters: where to cut, what to fix, and what to watch.
See every dollar across your entire data stack in one place. Break down spend by platform, team, pipeline, and time — no more switching between billing consoles.
Ask questions in plain English. “Why did our AWS bill spike last Tuesday?” or “Which dbt models are most expensive?” — get instant, cited answers.
Cross-provider AI cost dashboard — compare OpenAI vs Anthropic vs Gemini. Token breakdowns, model-level costs, and migration recommendations.
15 connectors for warehouses, pipelines, BI tools, AI models, and CI/CD. Read-only credentials. No agents or data extraction — we query APIs directly.
Catch cost spikes before they become surprise bills. Rolling-average baselines with per-platform thresholds alert you the moment something looks off.
Set daily, weekly, or monthly budget thresholds per platform or team. Get notified via Slack or email before you exceed targets.
From zero to full data stack visibility in under 5 minutes.
Add read-only credentials for any platform in your stack. OAuth where available, API keys otherwise. Each connector takes under 2 minutes.
Costs normalize into a unified model — warehouses, pipelines, BI seats, AI tokens, CI minutes — all in one place with consistent breakdowns.
The AI agent surfaces specific optimizations with projected savings. Review, approve, and in some cases execute changes directly from the UI.
The AI agent has 15 tools — one per connector — and can answer complex cross-platform questions instantly. No SQL, no pivot tables, no switching between billing consoles.
Why did our Claude spend spike last week?
Anthropic spend jumped +58% Mon–Thu. The driver is a prompt-caching regression — cache-hit rate fell from 71% to 12% on your sales-agent workflow after last Tuesday's deploy. An extra 41M cache-write tokens cost +$2.1K.
Every category of data infrastructure spend, in one unified model.
