Show HN: Built an open-source local firewall for AI coding agents

Hi Guys,

I built Guardian Runtime: a local FinOps and security proxy for AI coding agents (like Claude Code, Cursor, and Aider).

You point your agent to localhost:8080 instead of the real LLM API, and it sits in the middle to do three things:

1. Hard Budgets: Auto-kills the agent's internet access if it gets stuck in a retry loop and hits your daily spend limit. 2. Local Scanners: Instantly drops outgoing requests that contain leaked API keys or PII. 3. Terse Mode: Optimizes system prompts to force shorter answers, cutting your API output costs by 40–70%.

It runs entirely on your machine with zero cloud dependency, and supports OpenAI, Anthropic, and Gemini out of the box.

pip install guardian-runtime

I'd love to hear your feedback or see if you can break it!

Show HN: Automatic font clean-room reimplementor

Hacker News - Mon, 06/08/2026 - 11:25pm

Under US law, typefaces are uncopyrightable, but the font software is. This is a tool to reproduce typefaces via fully automatic clean-room reimplementation of the font software.
