Anthropic's billing console shows total spend, period. No per-developer breakdown. No per-session. No per-project. TrackCost shows all three.
No credit card · No code change in Claude Code · Works with your existing Anthropic key

CFO: Why did Anthropic charge us $3,247 last month?
You: Let me check the dashboard…
<Anthropic console: "Total spend: $3,247.18">
You: …it just shows the total. There's no breakdown.
CFO: Which person? Which feature? Which day spiked?
You: [no answer]
You're not flying blind because Anthropic is bad — they just don't expose this data. Their console is built for billing, not for ops. TrackCost is the missing layer.
Same data Anthropic has. Sliced by the dimensions you actually need.
Sarah: $487 · Marcus: $1,892 · Ali: $156
Marcus ran a multi-day agent session debugging a memory leak. You can SEE it now — and decide if it was worth it.
checkout-rewrite: $1,205 (37%)
Tag your API keys by project. Roll up costs by feature when justifying spend to the business.
3pm session: $42 · 12 turns
Catch the runaway sessions before the bill catches you. Set per-key budgets that actually block.
Claude Code reads ANTHROPIC_BASE_URL from env. Point it at TrackCost. Done.
Step 01 — Sign up & get an API key
Create your TrackCost account (free) → Providers page → paste your existing Anthropic key. Encrypted at rest with AES-256, never logged.
Step 02 — Set 2 env vars per developer
# In each developer's ~/.zshrc, ~/.bashrc, or .env: export ANTHROPIC_BASE_URL="https://api.trackcost.ai/api/v1" export ANTHROPIC_AUTH_TOKEN="acl_..." # their personal TrackCost key
Give each developer their own TrackCost key (named after them). That's how the per-developer breakdown lights up.
Step 03 — Run Claude Code normally
$ claude # works exactly the same # Costs flow through TrackCost in real-time # Open dashboard → see per-dev / per-session / per-day spend
Same with Cursor, Aider, Continue, any tool that supports ANTHROPIC_BASE_URL.

Anthropic charges this. Their console won't tell you who/why.
Visibility savings (industry avg)
$110 – $176/mo
Once you can SEE per-dev spend, the runaway sessions get caught early.
Estimates from Vantage's 2026 research on agentic coding costs: avg dev = $6/day, heavy users $20+/day.
