VibeWrench is a Swiss-army toolbox: 18 tools (security, speed, SEO basics, roasts, generators) from $0 to $19/month. CheckVibe is a dedicated scanning platform: 100+ security checks, 68 SEO + 46 AEO checks, uptime and threat monitoring, API and MCP server, from $0 to $59/month. Breadth of utilities versus depth of scanning.
TL;DR
VibeWrench (vibewrench.dev) takes the kitchen-sink approach: one subscription, 18 tools, from security scanning to landing-page roasts and README generation. Its security research (100 vibe-coded apps scanned, 318 vulnerabilities found) is genuinely useful reading. CheckVibe takes the opposite approach: fewer surfaces, much deeper scanning per surface, plus the monitoring layer. Facts verified against both sites on June 12, 2026.
| CheckVibe | VibeWrench | |
|---|---|---|
| How it scans | Live URL — tests the deployed app | URL, GitHub repo URL, or pasted raw code |
| Security depth | 100+ dedicated checks incl. live Supabase RLS probing, key exposure (100+ patterns), SQLi/XSS probing, JWT, CORS, dependencies | 1 of 18 tools — 9 coverage areas: secrets, injection, XSS, auth/session, CSRF, path traversal, dependencies, info leaks, config/headers |
| SEO scanning | 68 checks incl. structured-data depth, CrUX field Core Web Vitals, internal linking | Basic scan: meta tags, structured data, canonical URLs, mobile-friendliness, sitemap presence |
| AEO scanning (AI visibility) | 46 checks + 7-engine readiness matrix | Not mentioned on their site as of June 2026 |
| Monitoring | Uptime every 60s, threat detection, scheduled scans, regression alerts | Scan history (30–90 days); continuous monitoring not mentioned as of June 2026 |
| Extra tools | AI fix prompts, PDF reports, README badge | 18 tools: error translator, cost forecast, roast, prompt improver, README generator, legal docs, image optimizer… |
| Free tier | $0 — 1 project, 4 scans/month | $0 — 3 scans/month, all 18 tools, no signup needed for first scan |
| Pricing | Free $0 (4 scans/mo) · Starter $24/mo · Pro $39/mo · Max $59/mo (annual −30%) | Free $0 · Starter $9/mo (30 scans) · Pro $19/mo (unlimited scans, API 100/day) |

The fastest way to decide: scan your app with both.
CheckVibe's first scan is free — security, SEO, and AEO in about 30 seconds.
Run a free CheckVibe scanYes — VibeWrench runs $0/$9/$19 per month versus CheckVibe's $0/$24/$39/$59. The difference is scope: VibeWrench spreads across 18 general-purpose tools, while CheckVibe concentrates on deep security/SEO/AEO scanning plus continuous monitoring.
No AEO features or content appear on their site as of June 2026. Their SEO scan covers five basics (meta tags, structured data, canonicals, mobile, sitemap). CheckVibe runs 46 dedicated AEO checks including AI-crawler access, llms.txt, machine readability, and a per-engine readiness matrix.
Both will catch the common disasters (exposed keys, missing headers). CheckVibe goes further on backend configuration — live Supabase RLS probing, storage bucket exposure, edge function auth — and on injection testing breadth. VibeWrench adds a useful pre-launch checklist tool.
Both output copy-paste fix prompts for AI editors. CheckVibe additionally ships an MCP server, so Claude, Cursor, and other MCP clients can trigger scans and read results directly.
