Guardrail by NeatProxy

What it does

We burned real money running AI agents and didn't know why until it was too late. That's the whole reason Guardrail exists. It's a local proxy for Claude Code and Codex that shows you where every dollar goes, system prompt, tools, that MCP server you forgot about, before you spend it. When you're about to blow a budget, Guardrail blocks the request. Not after. Before. Built for developers who'd rather see the bill coming than explain it later.

Guardrail tracks AI coding-agent spend locally and blocks over-budget requests on supported proxy integrations. Codex with a ChatGPT subscription provides usage visibility, not blocking.

See coding-agent spend. Check your budget before the next supported request reaches the provider. Blocking requires a supported proxy integration. Codex with a ChatGPT subscription is visibility only; Cursor support is planned. Check compatibility . Scenario inputs stay in memory across marketing pages and audience switches. Reloading or entering the console clears them; shared links contain only the audience. A coding agent runs unattended for minutes at a time, and a single retry loop can burn more than a month of subscription before anyone looks. The tools that exist today tell you afterwards. Provider billing is a monthly rear-view mirror. By the time a number looks wrong, the money is…from neatproxy.com

  Free local security checks for AI coding in VSCode, Cursor and Windsurf2025 · ▲43

  Hi HN! We just launched Codacy Guardrails, an IDE extension with a CLI for code analysis and MCP server that enforces security & quality rules on AI-generated code in real-time. It hooks into AI coding assistants (like VS Code Agent Mode, Cursor, Windsurf), silently scanning and fixing AI-suggested code that has vulnerabilities or violates your coding standards, while the code it’s being generated. We built this because coding agents can be a double-edged sword. They do boost productivity, but can easily introduce insecure or non-compliant code. One recent research team at NYU found that 40%…

  Clipto MCP▲655

  Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

  Simple algorithm and color space to generate diverse skin tones▲627

  Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
