Stop AI Coding Drift Before It Ships: Introducing PreFlight

Overview

PreFlight is a local-first safety gate designed for AI coding workflows. It acts as a critical checkpoint in the development lifecycle to catch problems before they reach production. The tool uses a custom Micro-Fuzzer and Quantized CPG to detect hallucinated code, exposed secrets, and structural flaws. Because it operates locally on the user's machine, it ensures privacy and speed while keeping sensitive code safe from external servers.

Benefits

PreFlight offers several key advantages for developers who rely on AI to write code. First, it provides real-time monitoring through a background service called The Eye Daemon. This service watches file saves locally and alerts users immediately when issues arise. Second, the tool is fully compatible with the Model Context Protocol, which allows it to connect seamlessly with AI-native editors. Third, it includes a native Windows fallback that shows hard-block popups even if the main VS Code or Cursor extension is not installed. Finally, its local-first architecture means that code analysis happens on the user's machine, minimizing the risk of data exposure.

Use Cases

PreFlight is designed for a variety of development environments and workflows. It is ideal for terminal-only users who prefer command-line tools or for those setting up CI/CD checks. Developers using VS Code or Cursor can install the extension to get save-time squiggles and dedicated fix buttons. Even without the extension, the core engine continues to watch the project and provide alerts. The tool is also useful for teams that need shared security postures and policy enforcement. Organizations can use it to get shared risk-score dashboards and centralized visibility into remediation efforts.

Pricing

PreFlight offers a tiered pricing model to accommodate different needs, from individual founders to enterprise teams.

Free Tier ($0 forever)

This tier is designed for those starting with local-first safety and needing to prove the workflow. It includes unlimited local AST scanning, The Eye daemon, save-time IDE alerts, native Windows popup fallback, and MCP integration for AI-native editors. Users also get 10 free Deep-Reasoning AI Fixes.

Solo Founder ($19/mo)

Targeted at builders shipping AI-generated apps who require unlimited automated remediation. This plan includes unlimited Deep-Reasoning AI Fixes, complex architecture patches, and remediation for SQL, SSRF, authentication, and tenant-boundary issues. It also offers priority beta onboarding.

Teams ($49/seat/mo)

Designed for organizations requiring shared security posture and policy enforcement. This tier includes team policy enforcement, shared risk-score dashboards, centralized remediation visibility, and priority support.

Vibes

While specific user reviews are not detailed in the provided text, the product positions itself as a necessary bridge between rapid AI-assisted development and robust code safety. The emphasis on a free tier with generous limits suggests a strong community focus, while the availability of a free manual code audit service indicates a commitment to helping users understand their code's risks. The tool aims to be an invisible safety net that developers can trust without slowing down their modern AI workflows.

Additional Information

PreFlight offers a free manual code audit service for users who need a human-reviewed assessment. Users can send a repository, a live URL, or a suspicious code block. The team will review the highest-risk AI coding drift paths and email a detailed report. This service complements the automated tools by providing expert insight when deeper analysis is required.
