Market Evidence

monthly searches~ model estimate
Rising4 direct competitors
  • Target users:
  • Indie developers, AI tool site operators, vibe coding users, Claude Code / Codex / Cursor users, and small-team technical founders.
  • Builders shipping Next.js, React, Node.js, Supabase, Stripe, file upload, authentication, and admin dashboard features.
02

Competitive Landscape

  • Traditional competitors include Snyk, Semgrep, CodeQL / GitHub Advanced Security, and SonarQube. They focus on company codebases, CI/CD, and AppSec teams.
  • Newer AI security tools include Promptfoo, Garak, Pynt, Nox, VettIQ, Foil, ReconX, and OASIS. They cover LLM app security, AI code scanning, agent security, or benchmarking.
  • Anthropic's reference harness emphasizes starting with Day 1 threat modeling, static scanning, and triage, then moving toward autonomous scanning, triage, and patching in Week 2. That shows the real bottleneck is not only finding issues, but also prioritizing and fixing them.
  • The gap: most tools are either too enterprise-oriented, require repo/CI integration, or focus on LLM red teaming. Solo builders need a low-friction tool where they can paste a Next.js API route, React component, Node script, Supabase query, or AI-generated file and get launch-focused security feedback.

Differentiation Opportunity

- Product differentiation: focus on AI-generated code security, not generic enterprise SAST.

Why Build This

  • Target users:
  • Indie developers, AI tool site operators, vibe coding users, Claude Code / Codex / Cursor users, and small-team technical founders.
  • Builders shipping Next.js, React, Node.js, Supabase, Stripe, file upload, authentication, and admin dashboard features.
  • Real problems:
  • AI-written code often runs, but users do not know whether it has SQL injection, XSS, SSRF, path traversal, auth bypass, secret leakage, insecure CORS, or missing webhook verification.
  • Traditional SAST tools are too complex or produce too many findings for a solo developer.

How to Build (8h MVP)

Next.js

8h MVP Checklist

  1. 1.Build page structure and global SEO metadata.
  2. 2.Implement Scanner form, validation, authorization confirmation, loading, and error states.
  3. 3.Implement local heuristic security rules.
  4. 4.Implement `app/api/scan/route.ts` calling Anthropic API.
  5. 5.Define structured output schema and validate model responses with `zod`.
  6. 6.Implement risk score, severity summary, and finding cards.
  7. 7.Implement fix plan, patch suggestions, and regression test suggestions.
  8. 8.Implement Markdown report generation and copy.
  9. 9.Complete About, FAQ, FAQ schema, and Open Graph metadata.
  10. 10.Manually test with 3-5 example snippets: SQL injection, XSS, missing auth, insecure CORS, webhook missing signature.

Don't Build

  • Do not expand features without confirmation.
  • Do not add a complex backend unless core functionality requires it.
  • Do not start with login, payment, membership, or admin unless core functionality requires it.
  • Do not sacrifice launch speed for unnecessary completeness.
  • **Do not cut the core feature just to make the project lighter.**
  • Do not treat a static checklist as the MVP.
  • Do not scan third-party targets.
  • Do not generate weaponized attack chains.

Risks

  • Accuracy risk: LLMs can miss issues or produce false positives, so position the product as a prelaunch security self-check, not a replacement for professional audit.
  • Abuse risk: security tools can be misused, so restrict the product to owned or authorized code and avoid third-party target scanning or weaponized output.
  • API cost risk: a public free tool can be abused, so v1 needs input/output caps and later rate limiting or BYO-key mode.
  • Privacy risk: users paste code, so the product must not store code and must clearly say requests are sent to Claude API.
  • Competitive risk: Snyk, Semgrep, and GitHub Security are strong. Differentiation must stay focused on AI-generated code, indie builders, and actionable repair reports.
  • SEO risk: broad code-scanner terms are competitive, so use long-tail pages around `AI code security scanner`, `Next.js security scanner`, and `vibe coding security`.
