CheckVibe vs vas
Two scanners aimed at the same problem, built on opposite bets. CheckVibe sweeps everything visible from outside your app in about sixty seconds. vas signs in with test credentials and checks the thing that sweep cannot reach: whether one user can actually read another user's data. Full comparison below, including where CheckVibe wins.
Who wrote this: we build vas, so read accordingly. Every CheckVibe claim below comes from their own public pricing and product pages, checked in August 2026. Where they are better, we have said so rather than left it out, because a comparison you cannot verify is worth nothing to you.
The short answer
Choose vas if your real worry is whether one user can reach another user's data. vas signs into your application with test credentials and tries it, which a sixty-second external scan cannot do.
Choose CheckVibe if you want the widest surface sweep for the least money, you need API or MCP access on a cheap plan, you want daily monitoring, or you are an agency that needs white-label reports you can resell.
Where vas is stronger
One of these matters far more than the rest, so it goes first.
It signs in and tries to break the rules
Give vas optional test credentials and it logs into your application, submits your forms, and attempts to read records belonging to a different user, across up to 150 pages. That is a test of whether your access rules hold under a real session. No scan that runs from outside without credentials can answer that question, at any speed, because the page returns 200 whether the rule works or not. On Pro the whole pass runs automatically every week.
Every finding ships with a specific fix written to paste into your AI coding tool, on every paid plan.
Injection testing, breach monitoring against known credential corpora, and SPF, DMARC and DNSSEC checks on your sending domain, all in the same weekly pass.
Three saved projects on the $19 plan, against one on their entry tier.
Findings are ranked so a critical never sits below a missing meta description.
The difference that actually matters
CheckVibe advertises a full report in about sixty seconds. That is a genuine engineering achievement and it is the right target for what they are testing: headers, exposed keys, dependency versions, SEO and performance. All of it is observable from outside your application, without credentials.
The failure that actually takes down apps built with AI tools is not usually in that set. It is an access rule that looks right and is not. A Supabase policy that filters on a column the client controls. A route that checks you are logged in but never checks the record belongs to you. Nothing about those is visible from outside. The page returns 200 either way. The only way to find them is to hold a real session and try.
So vas takes optional test credentials, signs in, submits your forms, and attempts to read records belonging to a different user, across up to 150 pages. On Pro that whole pass runs automatically every week, and it includes injection testing, breach monitoring and email security records in the same run. It takes minutes rather than seconds, because there is no faster way to answer the question.
That is the honest trade. Sixty seconds buys you breadth. Signing in buys you the one class of finding that breadth cannot reach. Which matters more depends entirely on whether your app holds other people's data.

Where CheckVibe is the better choice
No tool wins everywhere, and these are the cases where we would point you at them instead. Taking them in order of how much they would matter if we were the ones choosing.
Their free tier is repeatable
CheckVibe's free tier runs as often as you like and returns a severity overview. The vas free tier is a single scan, once, for the life of the account. If you want to keep checking a side project without paying, theirs is the better deal and it is not close.
API and MCP access starts at their cheapest plan
CheckVibe includes an API key and MCP server support on the £17 tier. vas restricts both to Pro at $39. If you want to drive scans from a coding agent on a small budget, they are the cheaper route today.
Daily monitoring, where vas Pro is weekly
Their Pro tier re-scans daily. vas Pro re-scans weekly. For a site that ships several times a week, a daily cadence catches a regression sooner.
A real agency tier
Their top plan adds white-label reports, client workspaces with a portal, team seats, and the right to resell reports commercially. vas has no equivalent, and their lower tiers are marked internal-use only, so the resale right genuinely is a top-tier feature rather than marketing. If you audit client sites for a living, this is the deciding factor and vas does not compete.
Common questions
Is CheckVibe or vas better?
They solve different halves of the same problem. CheckVibe returns a full report in about 60 seconds across security, SEO, AEO and performance, and ships API and MCP access on its cheapest paid tier. vas runs a slower scan that logs into your application and tests whether one user can reach another user's data. If you want the broadest surface sweep for the lowest price, CheckVibe is the better fit. If your worry is that your access rules do not actually hold, that is what vas tests.
What does CheckVibe do better than vas?
Four things, honestly. Its free tier is repeatable rather than a single scan. It includes API and MCP access from its entry tier where vas restricts them to Pro. It offers daily monitoring where vas Pro runs weekly. And it has an agency tier with white-label reports, client workspaces and report resale rights, which vas has no equivalent of.
What does vas do that CheckVibe does not?
Authenticated testing. vas takes optional test credentials, signs into your application, submits its forms, and attempts to read other users' records across up to 150 pages. That is a test of whether your authorization holds, rather than a check of what is visible from outside. vas also checks email security records (SPF, DMARC, DNSSEC) and monitors your address against known breach corpora.
How much do they cost?
CheckVibe lists Starter at £17/month, Pro at £34/month and Max at £69/month. vas is Go at $19/month and Pro at $39/month. The tiers are close enough in price that cost is unlikely to be your deciding factor, so compare what each one actually tests instead.
Can I use both?
Yes, and for some teams that is the sensible answer. They overlap on configuration checks, so running both mostly duplicates effort there. The genuine complement is CheckVibe's dependency and supply-chain scanning alongside the authenticated access testing in vas, because neither tool covers the other's ground.
