Costura
Self-hosted AI spend attribution by person and API key
Costura turns every AI bill into one ledger: who spent what, why it moved, and which key has no owner. Connect read-only billing keys for Anthropic, Claude.ai, OpenAI, Codex, OpenRouter, Cursor and GitHub Copilot (experimental). Open source, self-hosted, provider keys stay encrypted on your infrastructure, no telemetry. A live demo is available.
Hunting this because AI bills are getting impossible to explain, and Costura answers who spent what and which key has no owner in one sentence each. I like that it is self-hosted and read-only, so provider keys never leave your infra, and there is a live demo you can poke at right away.
