This isn't "SAST bad, us good." Established SAST tools are excellent at what they were designed for. The point is that the design target matters: a tool built for a security team embedded in a large codebase makes different trade-offs than a tool built for a founder trying to answer one question — "is this safe enough to launch?"

What traditional SAST optimizes for

Classic SAST analyzes source code for known vulnerability patterns: injection, unsafe deserialization, vulnerable dependencies, and a long catalog of CWE categories. It's built to plug into a mature pipeline and to be tuned by people who can read its output.

  • Broad language and framework coverage across large, established codebases.
  • Deep CWE/vulnerability catalogs and dependency (SCA) scanning.
  • Designed for security engineers who triage, suppress and tune findings.
  • Often priced and scoped per developer/seat for ongoing team use.

The friction for an indie founder is real: SAST tools tend to produce long lists of findings with severity labels but little business context, assume you know which to ignore, and say little about the non-code parts of a launch (missing rate limits, Supabase RLS posture, webhook verification, robots.txt, error states).

What launch-readiness scanning optimizes for

Launch-readiness scanning asks a narrower, founder-shaped question. Instead of "list every static issue," it asks "what would block or embarrass this specific launch, and how do I fix it?" It is tuned for the patterns AI coding tools actually ship and translates findings into launch impact.

  • Tuned for vibe-coded patterns: client-side auth, missing RLS, exposed keys, IDOR, missing rate limits, unverified webhooks.
  • Findings ranked by launch impact and explained in founder-readable language with fixes.
  • Covers operational launch basics beyond code: SEO, error states, broken links.
  • Built to run once before launch, not to be tuned by a security team.

Which should you use?

Use the tool that matches your situation. If you have a security team, a large codebase and a mature pipeline, traditional SAST and SCA belong in your CI. If you're a founder trying to ship a vibe-coded SaaS without leaking customer data or running up a surprise AI bill, a launch-readiness review gets you to a safe launch faster and with less to interpret.

  1. Pre-launch solo founder: start with a launch-readiness scan; fix the blockers it ranks first.
  2. Growing team: add dependency scanning and a SAST tool in CI alongside launch-readiness checks.
  3. Regulated or high-stakes launch: pair either approach with a human security review.

The honest summary: SAST answers "what static issues exist in this code?" Launch-readiness scanning answers "is this safe to put in front of users, and what do I fix first?" For most indie launches, the second question is the one keeping you up at night.
