Milo's Launch Check vs Vibe App Scanner: an honest comparison
Different models for different needs. Vibe App Scanner (VAS) is an automated scanner you run yourself, as often as you like, on a monthly subscription, with a free first scan. Milo's Launch Check is a one-off, human-reviewed report in plain English with a fix prompt for every finding, from $29, plus an optional $19/month Monthly Watch. Choose VAS if you want to scan on demand many times a month, test logged-in areas, or plug a scanner into your coding agent. Choose Milo if you want one clear report a person has checked, no subscription, or a signed report to share. (VAS facts as of 17 October 2026, from its own site.)

When Vibe App Scanner is the better choice
- You ship changes often and want to re-scan on demand, many times a month (Go includes 20 scans a month, Pro 150).
- You want tests behind your login. VAS says its Pro deep scan logs in and tests authenticated access. We don't do that.
- You want your coding agent to start scans and read reports itself through MCP.
- You run several projects and want them all in one dashboard.
- You want results in minutes, not hours.
When Milo's Launch Check is the better choice
- You're not technical and want one plain-English report that a person has read, with the most important fix first.
- You don't want another subscription. Pay once ($29–$149), and add Monthly Watch only if you want it.
- You need something to share. Pro Check includes a signed PDF you can send to a client or attach to a data room. It isn't a certification or a pentest.
- You want strictly passive, consent-only checks of the public side of your app.
Can you use both?
Yes, and that's often sensible. Use an automated scanner to catch regressions as you ship, and a written, reviewed report before a launch, a raise or a client handover. Neither replaces a professional penetration test once you handle sensitive data or someone asks for one.

FAQ
Is Vibe App Scanner free?
VAS offers a free first scan that runs its full check suite and shows your score, issue counts and one finding in detail. Seeing every finding needs a paid plan. Its pricing page listed Go at $19/month and Pro at $39/month (as of 17 October 2026).
Does Milo's Launch Check test logged-in pages?
No. It's a passive check of the public side of your app. Deep Check reviews sign-in and payment flows from the outside, and you can optionally share Supabase policies or Firebase rules for review. If you need authenticated testing, an automated scanner with logged-in scans, or a professional pentest, is a better fit.
Which is cheaper?
It depends on how you use it. For one check, Milo's Quick Check is $29 once. If you want to scan on demand every month, a scanner subscription like VAS Go may cost less per scan. Milo's Monthly Watch is $19/month per app for one re-check every 30 days.
Is either one a penetration test?
No. Both are automated or passive checks. A penetration test is an expert-led, scoped engagement that actively tries to break in, usually costing thousands of dollars.
