A filtered Hacker News reader versus an AI agent sandbox escape proxy. Both Show HN projects launched within hours of each other — but they solve completely different problems.
TL;DR
These tools aren't really competitors — they serve entirely different audiences. HN Reader filters Hacker News stories by topic tags so you can skip the AI hype. Sandbox Agent helps AI agents escape their sandboxes while letting humans monitor what they do, using cryptographic puzzles and AWS Nitro Enclaves.

Use HN Reader if
A lightweight way to filter HN stories by topic tags. Good for developers who want to see programming, hardware, or history stories without the AI/ML flood. Side project — use it while it lasts.
Use Sandbox Agent if
For teams running AI agents that need outbound communication. The cryptographic time-lock means you can let agents share data while maintaining a monitoring window. Novel approach to an emerging problem.
No. HN Reader is a content filtering tool for humans browsing Hacker News. Sandbox Agent is infrastructure for AI agent communication. They're both Show HN projects but serve entirely different purposes.
The project is early stage. The cryptographic protocol is documented, and it uses AWS Nitro Enclaves for attestation, but there's no public production deployment or uptime guarantee. Worth watching if you operate AI agents.
Each story gets up to three tags (like "programming", "ai-ml", "llms"). You can filter your feed by these tags. The author acknowledges some overlap between tags but says it works well enough for personal use.
