caprock 0.1.5

Cut AWS Bedrock LLM spend from Claude Code — compression + prompt caching, on your machine.

caprock

Cut your AWS Bedrock LLM spend from Claude Code — context compression + prompt caching that actually work on Bedrock, on your machine, with your own credentials. Nothing leaves your machine.

pip install caprock          # or: uvx caprock
caprock wrap claude          # your Claude Code now runs through it
caprock stats                # see what you saved

Every session ends with the money you saved:

💰 You've saved $19.20 with caprock
   6,400,000 tokens cut · −85% input cost · 40 requests
   this month: $19.20 so far → ~$74/mo at this pace

Measured live against real Bedrock: −48% billed input on a clean install, −59.7% re-confirmed on a six-turn agent session, up to −70% with the full pipeline. Your number will vary with your workload — run caprock measure to see yours. How we got these: https://caprock.dev/methodology.

What it does

• Compression — shrinks tool outputs / logs / JSON before they reach the model.
• Prompt caching — makes Bedrock's prompt cache actually engage (stock Headroom's markers die in conversion → 0% on Bedrock; caprock fixes that).
• Savings meter — caprock stats and the end of every wrap session show what you saved, computed locally from real Bedrock cache tokens.
• Runs on localhost, signs with your Bedrock credentials. No caprock service in the request path — nothing leaves your machine.

Built on Headroom

caprock builds on the open-source Headroom project (Apache 2.0). It applies the general-purpose fixes that make caching and compression work on AWS Bedrock (contributed back upstream) over the stock headroom-ai package. Licensed Apache-2.0.
