VibeGuard
Open-source local MITM proxy that redacts secrets from your AI coding assistant requests and restores them in responses.
VibeGuard solves a narrow but real problem: your AI coding assistant sees your API keys, internal hostnames, and project names before you hit send. Its process-level intercept and hot-reload rule editing are the standout design choices—install, run `vibeguard claude`, and only that process is affected. If you already use a cloud DLP or need centrally managed policy across an org, this is not the tool; it's a local, developer-first layer. For individual developers and small teams who want something free, MIT-licensed, and auditable, it's a sensible install before your next Cursor or Codex session.

Skip VibeGuard if you need centrally managed DLP policy across an organization, or if you never launch your AI coding tool from the command line—it only protects processes started through its launcher.
Trusting a local CA certificate is a prerequisite, and corporate machines with certificate restrictions may not allow it—meaning install time you didn't budget for.
VibeGuard is free and open-source under Apache License 2.0, so there is no tier to outgrow. Compared with commercial DLP or AI-gateway products that charge per seat or per request, it costs nothing but your setup time; the trade-off is that it is a local developer tool with no centralized management or vendor support contract.
In short

About VibeGuard
VibeGuard is an open-source MITM proxy that runs locally and sits between your IDE/CLI and the AI API. When you launch a supported tool through its process launcher (for example, `vibeguard claude`), VibeGuard inspects the outgoing request and replaces sensitive values—API keys, internal IPs, project names—with placeholders such as `__VG_key_9d2e`, then restores the original values in the model's response. Detection is layered: rule lists, keyword matching, regex, and optional NER. The admin dashboard in your browser gives you a real-time audit log, visual analytics, and rule management, and rule edits apply instantly without a proxy restart (hot reload). Keyword and placeholder mappings are stored encrypted at rest using your local CA key. Setup is three commands: install, `vibeguard start && vibeguard trust`, then launch your tool through the proxy. Only traffic from explicitly launched processes is intercepted; the rest of your system network is untouched. It is aimed at developers and small teams who want a transparent, auditable privacy layer for cloud AI coding tools, and it is not a replacement for enterprise DLP with centralized policy management.
Behind the Verdict
The pitch is deliberately unglamorous, and that's a mark in its favor. VibeGuard is a local MITM proxy—the same class of tool as a debugging proxy—applied to a specific problem: keeping secrets out of AI coding assistant requests. The workflow is concrete. You install via a one-line script for macOS and Linux, or a PowerShell command on Windows. You run `vibeguard start && vibeguard trust` to bring the proxy up and trust its local CA certificate. Then you launch your AI tool through the launcher, e.g. `vibeguard claude`, so only that process's traffic is intercepted. The homepage's own example shows `sk-4f9a...x7z2` becoming `__VG_key_9d2e` and `192.168.1.100` becoming `__VG_ip_7bc4` before the request leaves your machine. Strengths worth noting: layered detection (rule lists, keywords, regex, optional NER) means you are not relying on a single redaction method; the admin dashboard gives a real-time audit log and analytics in the browser; rule edits hot-reload, so you don't restart the proxy every time you add a pattern; and the keyword-to-placeholder mappings are encrypted at rest with your local CA key. The process-level approach is the smart part—your other traffic is untouched, which makes it far easier to reason about than a system-wide interceptor. Weaknesses to go in with eyes open: it is a MITM proxy, so you are trusting a local CA certificate, and corporate machines may restrict that. Only processes launched through `vibeguard` are protected—anything you start normally is not. NER detection is optional and may need extra setup. It is a developer tool installed manually, not a managed service. And it targets coding assistant traffic specifically; if you want redaction for email, chat, or documents, this is the wrong shape of tool. The honest positioning: install it if you use Claude, Cursor, Codex, or similar with code and credentials you'd rather not paste raw into a cloud API, and you're comfortable with a local proxy and a CA cert. Look elsewhere if you need org-wide policy enforcement and reporting, or if you don't work from the command line.

Real-world workflow fit
Concrete scenarios for the personas VibeGuard actually fits — and what changes day-one when you adopt it.
Installs VibeGuard with the one-line script, runs `vibeguard start && vibeguard trust`, then launches Cursor via `vibeguard cursor` and works as normal.
Outcome: Project names, API keys, and internal hostnames are replaced with __VG_ placeholders before the request leaves the machine, and responses are restored so Cursor behaves normally.
Opens the browser admin dashboard, adds a regex rule for their internal service naming pattern, and relies on hot reload so the rule applies without restarting the proxy.
Outcome: New internal identifiers get redacted on the next request, and the real-time audit log shows exactly what was sent.
Uses the admin dashboard's audit log and visual analytics after a coding session to review which prompts contained redacted values.
Outcome: A clear, local record of redacted fields—no external data collection involved.
Use Cases
- Redact API keys and secrets from prompts sent to Claude or Cursor so credentials don't leave your machine.
- Replace internal server IPs and hostnames with placeholders before a request goes to GPT.
- Hide proprietary project names and codebase identifiers when using AI code review tools.
- Sanitize prompts automatically so you can use cloud AI coding assistants on sensitive code.
- Audit exactly what data is leaving your machine via the real-time audit log in the admin dashboard.
Models Under the Hood
as of 2026-10-17
Limitations
- VibeGuard is a local MITM proxy, so it requires trusting a local CA certificate—which may be restricted or blocked on corporate machines.
- It only intercepts traffic from processes you explicitly launch through `vibeguard`; tools started normally are not protected.
- NER-based detection is optional and may need additional setup.
- It is installed manually via a shell/PowerShell script, not a package-manager-managed service.
- Redaction targets AI coding assistant traffic specifically—not email, chat, or document workflows.
- It is not a centralized policy platform, so there is no org-wide enforcement or compliance reporting layer.

Where the pricing makes sense
The company stage and team size where VibeGuard's pricing actually pencils out — and where peers do it cheaper.
VibeGuard is free and open-source under Apache License 2.0, so there is no tier to outgrow. Compared with commercial DLP or AI-gateway products that charge per seat or per request, it costs nothing but your setup time; the trade-off is that it is a local developer tool with no centralized management or vendor support contract.
Setup time & first value
How long it actually takes to get something useful out of VibeGuard — broken out by persona, not the marketing-page minute.
Developers comfortable with a terminal: about 5–10 minutes—one-line install, `vibeguard trust` for the CA cert, then launch your tool. Non-developers or anyone on a locked-down corporate laptop: significantly longer, or blocked entirely, because trusting a local CA certificate may be restricted and rules may need manual tuning for your naming patterns.
Switching to or from VibeGuard
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From pasting secrets manually and hoping you catch them: install VibeGuard, run `vibeguard start && vibeguard trust`, then launch your assistant via `vibeguard claude`.
- ↗To a centralized DLP or AI gateway: disable or uninstall the local proxy—`curl -fsSL https://vibeguard.top/uninstall | bash`—and remove the trusted local CA certificate.
- ↗To no proxy at all: run the uninstall command with the purge flag on Windows or the uninstall script on macOS/Linux and delete the trusted CA cert.
