The five-question spine

Five questions you can’t answer for your own app right now.

PulseLight answers them in order — verdict, blockers, priorities, prompts, post-launch signals. The thing on your dashboard is the thing on your founder checklist.

  1. 01

    Can I launch?

    A plain verdict — Ready, Not yet, or Risky but shippable.

What we check

Seven pillars. Founder language.

Every check rolls up into one of seven pillars a non-engineer founder can name in one breath. The product never asks you to decode “CVSS 8.2” or “ASVS 2.1.3.”

From verdict to fix

We don’t just find it.

We hand your AI a prompt that won’t brick the codebase.

Every blocker comes with a restraint-engineered prompt for the tool you already use. Goal, affected files, working rules, what NOT to change, validation steps. Paste, ship, re-scan.

Copy prompt
<!-- pulselight prompt v2 -->

Goal:
Verify Stripe webhook signatures before processing events. The
`/api/stripe/webhook` route currently parses the body and trusts
event.type without calling stripe.webhooks.constructEvent().

Affected files:
- app/api/stripe/webhook/route.ts (line 22)

Working rules (enforced):
- Read raw body, NOT request.json(), so the signature can be
  verified against the literal bytes Stripe signed.
- Use STRIPE_WEBHOOK_SECRET from env. Do not hardcode.
- Reject with 400 on signature failure; do NOT log the body.

Do NOT:
- Migrate Stripe SDK versions.
- Touch other route handlers.
- Change the response shape.

Validation steps:
- Run: pnpm test apps/api -t webhook
- Confirm: invalid-signature request returns 400, not 200.
- Confirm: valid event still flips subscription_status.

Connected Checks

We read your live config too — not just your repo.

Repo scans stop at code. The things that actually hurt at launch live in dashboards you forgot to finish configuring. Connect once — we audit the live state on every scan.

  • Payments

    Stripe · Lemon Squeezy

    Webhook signatures, idempotency, and entitlements wired to real plans.

  • Data

    Supabase · Firebase

    Row-level rules, public buckets, and allow-all policies — audited live.

  • Hosting

    Vercel · Railway · Render

    Preview exposure, prod env leaks, and missing healthchecks on real deploys.

  • Auth

    Clerk

    Session rules, password policy, and exposed admin paths in your live tenant.

  • Observability

    Sentry · Better Stack

    Errors actually flowing and uptime checks actually running.

  • Product signal

    PostHog · Plausible · Canny

    Activation events, source attribution, and a real feedback path — installed and firing.

Connected Checks unlock at Growth. Infra platforms (Firebase, Railway, Render) unlock at Studio.

Recent findings

Three things we found last week — in apps that thought they were ready.

None of these caused a launch failure, because PulseLight surfaced them in time. None of them would have shown up in a repo scan alone — you have to read live platform config too.

Aggregated from anonymised scans the week ending Sunday. We never share repo names, contributor handles, or any code — the number is the only thing that leaves the workspace.

Verdict first. Evidence on demand.

The verdict reads in five seconds. The evidence is one click away.

You shouldn’t have to decode rule IDs to know if your app is ready. Most sessions live in the verdict + Top 3. Technical evidence is preserved but only shows up when you ask for it — the same shape your scan reports take when you share them.

Level 1

Verdict

One sentence. The first thing a founder reads on every scan.

What we are not

PulseLight isn’t a scanner.

SAST tools tell your security team about CVEs. APM watches after things break. Compliance automation prepares you for an auditor. None of those help you, the founder, decide if it’s safe to put your AI-built app in front of real users today.

PulseLight is

  • A pre-launch readiness verdict for AI-native builders.
  • A Top 3 next-actions list, ordered by stage and severity.
  • A bridge between scan output and the AI tool you already use.
  • Stage-aware: pre-launch hides what doesn’t matter yet.

PulseLight is not

  • Generic SAST or AppSec tooling for security teams.
  • Runtime APM, log aggregation, or observability.
  • SOC 2 / GDPR compliance automation for auditors.
  • A 200-rule wall demanding triage from a non-engineer.

Frequently asked

Questions founders ask first.

  • Is PulseLight a SAST / security scanner?

    Not really. PulseLight checks security, but it also checks billing, monitoring, onboarding, analytics, deployment, and trust signals — the things AI-built apps quietly skip. Generic SAST is built for security teams; PulseLight is built for the founder who has to ship.

  • Will PulseLight modify my code?

    No. PulseLight reads your repo and your connected platforms (Vercel, Supabase, Stripe, etc.) read-only. The product never opens a PR or pushes a commit. Fixes happen in your AI tool of choice using a paste-ready prompt we generate.

  • How is this different from Sentry, Datadog, or Snyk?

    Sentry / Datadog watch your app after something breaks. Snyk tells your security team about CVEs. PulseLight tells you, before launch, whether the app is ready for real users — across security, billing, monitoring, recovery, and trust.

  • I'm pre-revenue. Is this for me?

    Yes — pre-launch is the most relevant stage. PulseLight is stage-aware: pre-launch hides scaling-only checks; first-100-users adds activation funnel signals; scaling adds cost / churn / DB hotspot checks. You only see what matters now.

  • How long does the first scan take?

    About 60 seconds for a typical Next.js / SvelteKit / Express repo. The free pre-signup scan is the fastest way to see the verdict — connect your repo, get the verdict, decide whether to sign up.

  • Do you support my AI tool?

    PulseLight generates restraint-engineered prompts for Cursor, Claude Code, Lovable, Bolt, v0, Replit Agent, Windsurf, and Aider. Each prompt is shaped so the tool fixes the issue without sweeping refactors or unrelated changes.
