CheckVibe vs VibeWrench: which should you use?
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: 18 tools including security scan (9 coverage areas), basic SEO scan, Lighthouse speed, roast generator, README generator — free 3 scans/mo, $9–19/mo paid.
- CheckVibe: dedicated scanner — 100+ security checks incl. live Supabase RLS probing, 68 SEO checks, 46 AEO checks, uptime + threat monitoring.
- VibeWrench is cheaper; CheckVibe goes deeper per category and adds AEO, which VibeWrench doesn't cover at all as of June 2026.
- VibeWrench scans URLs, GitHub repos, or raw code; CheckVibe scans the live deployed app.
- Both output AI-ready fix prompts for Cursor/Claude.
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.

Choose CheckVibe if…
- You want scanning depth: 100+ security checks and live Supabase RLS probing versus a 9-area security pass.
- You care about AI-search visibility — CheckVibe's 46 AEO checks and per-engine matrix have no VibeWrench equivalent.

- You want MCP integration to scan from Claude, Cursor, or any MCP client.
Choose VibeWrench if…
- You want the lowest price — $9/month buys 30 scans plus all 18 tools.
- You want the utility belt: roast my landing page, generate a README, translate an error, forecast costs.

Is VibeWrench cheaper than CheckVibe?
Yes — 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.
Does VibeWrench do AEO?
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.
Which is better for a pre-launch security check?
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.
Do both work with Cursor and Claude?
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.
