Defexity vs Vibe App Scanner
Last updated · 3 min read
Both scan live AI-built apps and source code and give copy-paste fixes for AI tools. Vibe App Scanner is paid after a 7-day trial ($29 or $49 a month) and its Pro plan adds weekly monitoring, breach and email checks. Defexity has a free plan, marks a fix resolved only when a recheck passes, and monitors sign-up and checkout flows after deploys.
Side by side
| Vibe App Scanner | Defexity | |
|---|---|---|
| Price | Go $29/month, Pro $49/month, after a 7-day trial | Free plan, no trial limit; paid from $15/month ($12.50 billed yearly) |
| Free option | Trial: three full URL or repository scans | Free forever: 2 scans per URL per day, every finding with a fix prompt |
| Live-site scan | Yes (20 a month on Go, 150 on Pro) | Yes, 130+ read-only checks |
| Code scan | GitHub or ZIP upload (10 a month on Go, 50 on Pro) | ZIP upload on every plan; GitHub on Pro and Agency |
| Fix prompts for AI tools | Yes, listed on Go | Yes, on every plan |
| Confirming a fix | Re-scan on demand; their page says non-detection alone is not a confirmed fix | One-click recheck; a finding is marked resolved only when it passes |
| Ongoing monitoring | Pro: weekly monitoring with alerts, weekly extended scans | Indie and up: up to 3 monitored flows (sign-up, login, checkout) with email alerts, plus deployment checks |
| Flow tests (sign-up, checkout) | Not described | Yes, on a schedule and after deploys (paid plans) |
| Breach and email security checks | Pro | Not offered |
| MCP server for AI agents | Yes (Pro and eligible AppSumo plans) | No public MCP server; scans and deployments by API key |
Where Vibe App Scanner is stronger
Vibe App Scanner covers some areas Defexity does not: breach monitoring and email security checks on Pro, and weekly extended scans with authenticated testing when configured. It also has a remote MCP server, so an AI agent such as Cursor or Claude Code can start scans and read reports directly.
Its code scanning includes GitHub on both paid plans, where Defexity connects GitHub only on Pro and Agency.
Where Defexity is different
Defexity has a free plan with no trial limit, so the core loop (scan, copy a fix prompt, recheck) costs nothing for one app. Every finding comes with a fix prompt on every plan.
A fix counts only when a recheck of the live site passes, so the report tracks what is actually fixed rather than what was attempted. On paid plans Defexity also runs your sign-up, login and checkout flows in a real browser on a schedule and after deploys, which catches regressions a scan cannot see, such as a checkout that stops confirming orders.
Which to choose
- Want breach and email security monitoring, or to drive scans from an AI agent over MCP: Vibe App Scanner Pro.
- Want a free plan, verified rechecks, or monitoring of the flows that make you money: Defexity.
- Not sure: scan the same URL with both. A second tool’s findings are the fastest way to spot what one scanner missed.
Questions
- Is Vibe App Scanner free?
- Not after the trial, as of 13 November 2026: a 7-day trial with three full scans, then $29 or $49 a month. AppSumo lifetime plans keep their own terms.
- Do both scan the code as well as the live site?
- Yes. Both read a deployed URL and source code; each says a URL scan cannot see private source and a code scan does not test the deployment.
