What it does
PreFlight is a local AST-based security gate that guards your codebase against AI hallucinations. AI coding agents often "quietly" skip critical security protocols like Supabase Row-Level Security (RLS) or leak server-only logic. PreFlight parses your code's AST in real-time, mapping your architectural dependencies to catch these structural drifts. Currently in public beta. Open-source, local-first, and built for developers who want to keep the speed of AI without the security debt.

KastraJul 2026 · kastra.ai · ▲332Hi HN, Fernando and I built Kastra. Kastra intercepts AI agent tool calls and evaluates them against deterministic policies before they execute. We built this product to control pre- and post-inference workloads. This is aimed at developers using coding agents like Claude Code, Codex, Cursor, and OpenClaw. Kastra pushes an allow, hold, and deny decision before the action runs. You can build these policies in plain English from the web app. The interception engine evaluates the tools, targets, and parameters of every action at sub 1ms at a scale of billions of interceptions per day. We also…


PreflightDec 2025 · preflightqa.xyz · ▲77Hey HN, I’m a product designer on a payments team. Every time we were close to shipping a feature, we’d run a bug bash in a giant Google doc or spreadsheet: copy the spec in, write the test cases, ask people to mark Pass/Fail, paste screenshots, then manually turn everything into Jira tickets. It worked, but it always felt a bit painful. Instead of another heavy test management tool, I wanted something that feels closer to the tools we actually like using. More Linear/Notion, less old-school QA. With Preflight, you paste your product requirements and Figma link and get an initial…

PreloopJan 2026 · preloop.ai · ▲121Hey HN, I’m Yannis, co-founder of Preloop. We’ve built a proxy for the Model Context Protocol (MCP) that lets you add human approval gates to your AI agents without changing your agent code. We’re building agents that use tools (Claude Desktop, Cursor, etc.), but we were terrified to give them write-access to sensitive systems (Stripe, Prod DBs, AWS). We didn't want to rewrite our agents to wrap every tool call in complex "ask_user" logic, especially since we use different agent runtimes. We built Preloop as a middleware layer. It acts as a standard MCP server proxy.You point your agent to…

Homebrew 6.0.0▲1,481Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
