pxpipe: An open-source proxy that cuts LLM token usage by rendering text context as images

Summary

pxpipe is a local proxy tool that reduces token usage in Claude Code (and similar LLM applications) by converting bulky text context — such as system prompts, tool documentation, code, JSON, and history — into compact PNG images before sending them to the API. Since image token costs are determined by pixel dimensions rather than text density, dense content achieves roughly 3.1 characters per image-token compared to ~1 character per text-token. The approach leverages the same vision channel Anthropic's computer use feature uses for screenshots. The tool is open-source and available on GitHub.
