Introducing Pithos — Cut your AI coding bill by up to 45%, 100% locally.
Today, we are thrilled to announce the launch of **Pithos**! Pithos is a local proxy middleware and VS Code integration that gives you full control over how coding agents utilize tokens.
If you have been building software with agentic tools like Cline, Roo Code, Claude Code, or Aider, you know the pain: as workspaces expand, outgoing context payloads scale exponentially. A simple prompt can quickly consume hundreds of thousands of tokens. This results in heavy monthly billing cycles, slow responses, and redundant cache misses.
How Pithos Solves This:
- Tool Output Compression: A Claude Code hook strips test/build/lint noise and minifies JSON from Bash output before it reaches your context.
- Read Deduplication: Re-reading an unchanged file returns a one-line notice instead of the full content again.
- System Prompt Caching: Rearranges system rules and instructions into a stable sequence to hit Anthropic's prompt caching discounts.
- Total Privacy: Runs completely offline. Pithos does not relay your codebase or secrets to any remote server. Your code stays on your machine.
We are launching with a flat-rate **$19/month Pithos (VS Code) plan**, allowing you to bypass token-volume markups entirely.
