VibeGuard
Open-source local proxy that redacts sensitive data from AI coding assistant requests
VibeGuard fills a real privacy gap for AI-assisted coding with minimal friction. It's free, open-source, and zero-config—worth installing if you use Claude, Cursor, or Codex with sensitive code. Unlike enterprise DLP, it's developer-first and local. The process-level intercept and hot-reload rules are standout features. For teams needing centralized policy control, consider a cloud-based DLP; for pure convenience, VibeGuard is a solid choice.

Skip VibeGuard if you need enterprise-grade DLP with centralized policy management, or if you're a non-developer who doesn't use CLI tools or AI coding assistants.
You must trust a local CA certificate, which might be blocked by corporate IT policies—so it may not work in locked-down environments.
VibeGuard is free and open-source, making it a zero-cost option for individual developers and small teams. Compared to enterprise DLP solutions that charge per seat or per month, VibeGuard offers similar core redaction features at no price—though it lacks centralized management. For privacy-focused developers on a budget, it's the cheapest way to protect AI coding traffic.

About VibeGuard
VibeGuard is an open-source MITM proxy that runs locally on your machine. It automatically redacts sensitive information—like API keys, IP addresses, and project names—from requests sent to AI coding assistants (Claude, Cursor, Codex, GPT, Gemini), then restores the original data in the response. You launch your AI tool through VibeGuard's process launcher (e.g., `vibeguard claude`), so only targeted processes are intercepted, leaving your system network untouched. It's designed for developers who want privacy without slowing down: zero-config out-of-the-box defaults, a hot-reload admin dashboard for rule edits, and multi-layer detection (rule lists, keyword matching, regex, optional NER). All keyword-to-placeholder mappings are encrypted at rest using your local CA key. VibeGuard is free, Apache 2.0 licensed, and auditable—ideal for indie devs and teams needing a simple, transparent privacy layer. It's not for non-developers or those needing centralized policy management.
Behind the Verdict
VibeGuard targets a specific pain point: developers who want to use AI coding assistants without leaking proprietary code, API keys, or internal IPs. The local, process-level proxy design is clever—it doesn't touch your system network, and you only protect the tools you explicitly launch. The zero-config install and hot-reload admin dashboard lower the barrier to entry significantly. Multi-layer detection (rule lists, keyword, regex, optional NER) gives flexibility, and encrypted storage of mappings with your local CA key is a thoughtful touch. Strengths: Easy setup (one-line install), free, open-source, auditable. Process-level intercept means you control exactly what's filtered. Hot-reload rules mean no restarts. The admin dashboard provides real-time audit and analytics—great for seeing what's actually sent to AI APIs. Weaknesses: Requires trusting a local CA certificate, which may be restricted in corporate environments. Only intercepts traffic from processes launched via its launcher, so tools started outside won't be protected. NER detection is optional and may need extra setup. It's not a centralized DLP—no policy management or reporting across a team. And it's manual install, so non-developers will struggle. Where it fits: Indie devs, privacy-conscious individuals, small teams using Claude/Cursor/Codex with sensitive code. Where it doesn't: enterprise teams needing centralized policy enforcement, non-developers, or anyone who can't trust a local proxy.

Real-world workflow fit
Concrete scenarios for the personas VibeGuard actually fits — and what changes day-one when you adopt it.
Install VibeGuard with one line, trust the CA, and launch `vibeguard claude`. The proxy automatically redacts API keys and internal IPs from prompts before they hit the API, and restores them in responses.
Outcome: You can safely use Claude Code on proprietary codebases without worrying about leaking secrets, and you can audit exactly what was sent via the admin dashboard.
Run `vibeguard cursor` to start Cursor through the proxy. Your prompts and code snippets are filtered for sensitive patterns (regex, keywords, NER) before leaving your machine.
Outcome: Sensitive data like server hostnames and project names are replaced with placeholders, protecting your IP while maintaining a smooth coding flow.
Set up VibeGuard on each developer's machine and launch GPT via the launcher. The admin dashboard provides a real-time audit log, so the team can monitor what's being sent.
Outcome: The team gets a lightweight, auditable privacy layer without heavyweight DLP tools, and can adjust rules on the fly.
Use Cases
- Redact API keys and secrets from prompts sent to Claude or Cursor to avoid leaking credentials.
- Replace internal server IPs and hostnames with placeholders before sending requests to GPT.
- Hide proprietary project names and codebase identifiers when using AI code review tools.
- Safely use cloud-based AI coding assistants with sensitive intellectual property by automatically sanitizing inputs.
- Audit exactly what data is being sent to AI APIs via the real-time audit log in the admin dashboard.
