vibeGuard
vibeGuard (site) is a Chrome extension that scans web apps for security issues in real time, with no signup and no pricing tiers at all — it's simply free. It suits solo coders and hobbyists who want a lightweight, browser-based check without installing anything on their codebase. The limitation: it works in-browser on web apps, not inside your coding agent, so it doesn't intercept dangerous commands or scan diffs before commit the way VibeDefend does.
VibeShield
VibeShield (site) is a free full-version macOS download that finds exposed risks on vibe-coded apps before attackers do. It suits Mac-based developers who want a standalone scanner rather than an agent integration. Pricing details beyond the free download aren't stated, and the product's own pricing page actually belongs to a different product (Creative Dashboard), so treat any future paid tier as unconfirmed. It doesn't run inside Cursor or Claude Code sessions.
VibeLint
VibeLint (site) blocks AI code vulnerabilities in real time and offers a free tier with no credit card required. It suits developers who want a lighter-weight alternative to VibeDefend without committing to a paid plan upfront. Paid pricing isn't published, so you can't yet compare total cost against VibeDefend's $19/month tier. It's a newer launch (April 2026) with limited public track record so far.
Vibesecur
Vibesecur (site) is a security scanner built specifically for Lovable, Cursor and Bolt apps, with a free scanner that requires no account. The first 500 users get the Solo tier free for three months, which makes it attractive for early adopters of those specific platforms. It suits builders on Lovable or Bolt rather than general Claude Code or Windsurf users. Enterprise pricing and the eventual Solo price after the promo aren't disclosed.
VibeWrench
VibeWrench (site) scans AI-built apps before shipping and gives all 18 tools on its free plan (3 scans/month), with Starter at $9/month for 30 scans and Pro at $19/month for unlimited scans. It suits solo developers who want full tool access cheaply and can live with scan limits below Pro. At $9/month it undercuts VibeDefend's Developer tier, but it scans finished code rather than intercepting writes before they happen inside the agent session.
Trust
Trust (site) is a security scanner built for vibe coders, with a free tier of 5 URL scans and 3 GitHub repo scans per month plus 2 AI analyses. Pro is $9.9/month at launch (regular $12/month) for unlimited scans. It suits budget-conscious solo coders who scan occasionally rather than continuously. Like most alternatives here, it scans repos and URLs rather than guarding the live coding session the way VibeDefend's in-agent guard does.
ShipSafe
ShipSafe (site) offers a free pattern-based Quick Check with no AI and no card, plus paid plans from $19/month (Solo, 4 AI scans) up to $49/month (Growth, 20 AI scans), and a one-time audit option. It suits teams who want occasional AI-backed scans without a subscription-first model. It matches VibeDefend's $19/month entry price but caps AI scans per month rather than running continuous in-agent protection on every diff.
How to choose
If you want something completely free with no setup, start with vibeGuard or VibeShield. If you're testing real-time blocking without committing money, try VibeLint or Vibesecur, though their paid pricing is still unpublished. If you want a low monthly cost with known pricing, VibeWrench ($9/mo) or Trust ($9.9/mo) are the cheapest confirmed options. If you specifically need rules mined from your repo and commands blocked before they run in Claude Code or Cursor, VibeDefend or ShipSafe (both $19/mo) are the closest matches.
