The only tool that proves savings before you change anything.

You pay nothing unless we save you money
Performance-based pricing

The audit is free. The optimization proxy is free until it saves you $500/mo. After that, 15% of verified savings. If we don't find anything, you owe nothing. Every dollar is verifiable against your own provider invoices.

Audit first, route second
Prove the case before changing anything

Other tools ask you to reroute traffic before proving value. Clawback replays your actual calls offline, scores quality per prompt, and delivers a savings receipt. No production risk. No infrastructure to deploy. Decide after you see the numbers.

Quality gate on every prompt
Not "downgrade everything"

Clawback tests each call type against lower-cost models and scores output quality with 95% confidence intervals. Only recommends a swap when quality holds. Classification calls, extraction calls, summarization calls — each evaluated independently against your production output.

Five minutes. No engineering sprint.

Your API keys are read from your local environment at call time and never stored by Clawback. Call metadata is stored encrypted in Cloudflare KV (encrypted at rest, SOC 2 certified) for up to 30 days and automatically purged after report generation. Full security overview.

The audit is free, forever. Clawback Pro is $0 until your verified savings exceed $500/mo. After that, you pay 15% and keep 85%. Example: last month you spent $5,000 on LLM calls. With Clawback routing, you spent $3,000. Savings = $2,000. Clawback fee = $300. You keep $1,700. Every dollar verifiable against your own provider invoices.

You still get the full free audit report showing your total savings potential and aggregate quality scores. You just don't pay anything. When your usage grows past the $500/mo savings threshold, billing starts automatically at 15% of verified savings.

You could. But next month, OpenAI drops a new model. Anthropic updates pricing. Google launches Flash 2.0. Do you want to re-evaluate every endpoint every time? Clawback does it automatically, continuously, while you ship product. We monitor model releases and re-optimize your routing in real time.

We monitor model releases across all major providers. When a new model launches, we automatically re-evaluate your traffic and notify you of additional savings opportunities. You don't track model releases. We do.

The free audit shows your total savings potential, aggregate quality scores, and optimization categories. The paid proxy adds the per-call routing map, automated model switching, response caching, cost-per-feature attribution, budget caps, spend alerts, and provider fallback. The audit proves you can save. The proxy captures it.
