Security scanner for AI-vibecoded apps

What to build

A security-audit tool for apps built on AI-assisted coding platforms (Lovable, Bolt, Replit, Cursor) that scans the live app and codebase for exposed API keys, missing auth rules, and open database permissions, then returns a fix-it report (or auto-patches) for solo vibecoders.

Bubble is marketing its new MCP release partly on built-in security (auth rules, data permissions), implicitly signaling that competing AI-assisted stacks ship insecure defaults — a gap a lightweight third-party audit tool could fill for builders on those platforms.

Demand

Solo builders and vibecoders shipping fast on Lovable, Bolt, Replit, and Cursor commonly leave exposed keys and open database rules in production; Bubble's security-first pitch for MCP is pushing this anxiety into the open right as these builders look for a quick, cheap way to check their app before launch.

• r/nocode (Reddit)Community discussion

  Reddit thread on r/nocode discussing Bubble's MCP launch, noting people repeatedly running into Bubble as the platform with its own MCP to connect AI and build apps.

• Signal: Bubble MCP is outProduct launch

  Bubble's MCP integration is marketed with built-in auth rules and data permissions as a key differentiator, implying rival AI-assisted builders lack equivalent protection.

• Opportunity analysis (internal)Analysis

  Analyst note: AI-assisted builders (Lovable, Bolt, Replit, Cursor) commonly ship exposed keys, missing auth, and open DB permissions by default, and users would plausibly pay for an automated audit-and-fix tool.

Stack

• Node.js CLI / GitHub App
• Static analysis (regex + AST scanning for secrets)
• Supabase/Postgres permission inspection APIs
• GitHub REST API for repo scanning
• Gitleaks or TruffleHog for secret detection
• Next.js dashboard for report delivery

Solo + AI difficulty

Secret-scanning and basic auth/permission checks are easy to ship fast with existing open-source scanners (gitleaks) as a base; the hard part is reliably detecting platform-specific misconfigs across Bubble, Lovable, Bolt, Replit, and Cursor since each has different data models. A credible single-platform MVP (e.g. Supabase/Replit) is feasible in 1-2 weeks; broad multi-platform coverage takes much longer.

Entry threshold

Buildable solo in days to weeks using static code scanning plus checks against common backends like Supabase, Firebase, and Vercel; no licences or capital needed, just engineering time and access to public platform APIs.

Counter-signals & risks

• No direct evidence yet that end users of Lovable, Bolt, Replit, or Cursor are actively seeking or paying for a third-party security-audit tool; the opportunity is inferred from Bubble's marketing angle rather than observed demand.

• Platforms like Replit and Cursor may already be building or planning native security-scanning features, which could undercut a standalone third-party audit tool.

• A generic scanner may struggle to reliably detect platform-specific misconfigurations across heterogeneous stacks (Bubble, Lovable, Bolt, Replit, Cursor), limiting accuracy and perceived value.
