Coolify is an open-source self-hosted PaaS with 29K+ GitHub Stars — a free Heroku/Netlify alternative that runs on your own server and deploys any Docker or Git-based app with a visual UI. But as a deployment platform, it has no built-in WCAG accessibility audit, no Core Web Vitals scoring, and no front-end health monitoring for the apps it deploys. PageGuard audits the live URL of any Coolify-deployed application — free, no server access needed, results in 30 seconds.
ADA Title II Deadline: April 24, 2026
State and local government websites must meet WCAG 2.1 AA by April 24, 2026. Government agencies, nonprofits, and educational institutions that self-host web applications with Coolify face this compliance deadline. Coolify’s Git auto-deploy and Docker Compose stack deployments mean any push to production can introduce front-end accessibility regressions instantly — new components, updated templates, or one-click stack upgrades can push WCAG violations without any automated quality gate. PageGuard provides continuous post-deployment front-end monitoring without requiring server access or code changes.
| Feature | PageGuard | Coolify |
|---|---|---|
| What is it? | External website health monitor — scans any URL for performance, accessibility, SEO, and best practices | Open-source self-hosted platform-as-a-service (PaaS) — a self-hosted alternative to Heroku, Netlify, and Vercel that runs on your own VPS or dedicated server; deploys web apps, static sites, databases, and background workers from Git with one-click Docker Compose stacks, automatic SSL certificates, and a visual UI; 29K+ GitHub Stars |
| Free tier | ✓ Yes — unlimited one-off scans, no signup required | Yes — Coolify Community Edition is fully open-source and free to self-host on any server; Coolify Cloud (managed hosting of the Coolify platform) starts from $5/month; no usage limits beyond your own server capacity |
| Accessibility audit (WCAG / ADA) | ✓ Yes — WCAG 2.1 AA scored 0–100 with specific issue list | No — Coolify is a self-hosted deployment platform; it builds and runs your application code on your own server but has no built-in WCAG or ADA accessibility auditing for the front-end HTML rendered by deployed applications; accessibility quality is entirely determined by the application code and templates developers deploy |
| Technical SEO audit | ✓ Yes — meta tags, headings, canonical, structured data | No — Coolify provides no SEO audit scores, meta tag validation, heading hierarchy checks, or structured data analysis; all SEO implementation is the responsibility of the deployed application code |
| Performance audit (Core Web Vitals) | ✓ Yes — LCP, CLS, FCP scored 0–100 per scan | No — Coolify provides no Core Web Vitals measurement (LCP, CLS, FCP, INP) for hosted applications; it manages server-side deployment and infrastructure on your VPS but does not measure front-end rendering performance from a user perspective |
| Self-hosted application deployment | No — PageGuard is a monitoring tool, not a hosting platform | ✓ Yes — Coolify deploys any Dockerfile, Docker Compose stack, or buildpack-based application on your own server; visual UI for managing services, environment variables, domains, and SSL; one-click stacks for popular apps (WordPress, Ghost, Nextcloud, MinIO, Supabase, and 100+ more); real-time deployment logs; automatic backups |
| Git-based deployment | No — PageGuard is a browser-based monitoring tool | ✓ Yes — connect GitHub, GitLab, or Gitea repository and Coolify auto-deploys on push; webhook-triggered deployments; branch-based preview environments; rollback to any previous deployment; zero-downtime deployments via health checks |
| Automated website monitoring | ✓ Yes — weekly or daily scans with email alerts on score drop | No — Coolify is a deployment and infrastructure management platform; it has no post-deployment front-end health monitoring for WCAG compliance, Core Web Vitals regressions, SEO quality, or best practices for rendered HTML; Coolify monitors container health and uptime — not front-end quality metrics |
| AI-generated plain-English report | ✓ Yes — explains issues in non-technical language | No — no front-end health report for applications deployed via Coolify |
| ADA Title II compliance monitoring | ✓ Yes — WCAG audit + alert on accessibility regression | No — Coolify does not audit or alert on WCAG compliance for hosted apps; government agencies, nonprofits, and educational institutions that self-host web applications with Coolify face ADA Title II compliance requirements; common accessibility issues include server-rendered templates missing ARIA landmark roles, React or Vue SPAs with insufficient color contrast, missing alt text on CMS-managed images, and keyboard navigation gaps — all requiring external runtime validation after each deployment |
| Works on any platform | ✓ Yes — scans any URL on any front-end or platform | No — Coolify deploys only your own applications on your own servers; it does not audit sites or applications hosted on other platforms |
| Independent external audit | ✓ Yes — third-party scan, shareable URL for clients/stakeholders | No — no built-in tool to generate a shareable external front-end health report for applications deployed via Coolify |
| Instant on-demand scan | ✓ Yes — results in 30 seconds, no code changes needed | No — no on-demand front-end health scan; auditing Coolify-deployed applications requires separate tools like Lighthouse or axe after each deployment |
| Multi-site dashboard | ✓ Yes — 1–50 sites depending on plan | Coolify organizes deployments by server and project in its UI; there is no health monitoring dashboard showing WCAG accessibility, SEO, and Core Web Vitals scores across multiple deployed applications |
| Pricing for health monitoring | ✓ Free + from $9/mo for automated monitoring | Health monitoring not available — Coolify is an open-source self-hosted deployment platform, not a website health monitoring tool; Coolify CE is free (self-hosted), Coolify Cloud starts at $5/mo |
Get WCAG accessibility scores and Core Web Vitals for any Coolify-deployed application. Results in 30 seconds. No server access, Coolify account, or code changes required.
Results in ~30 seconds. 4 scores: Performance, Accessibility, SEO, Best Practices.
Yes — PageGuard scans the live URL of any application deployed via Coolify. Enter your app’s public URL and receive a full health report in ~30 seconds covering Core Web Vitals, WCAG 2.1 AA accessibility, technical SEO, and best practices. No Coolify account, server SSH access, or application code is required.
No — Coolify is a self-hosted deployment platform with no built-in WCAG compliance checking. It deploys and manages application containers on your server but does not audit the front-end HTML output for accessibility issues. Common problems include missing alt text, improper heading hierarchy, insufficient color contrast, missing ARIA labels on interactive components, and keyboard navigation gaps in JavaScript SPAs. PageGuard audits your live Coolify-deployed app and provides a WCAG 2.1 AA score with specific issues to fix.
Coolify’s Git auto-deploy means any push can send front-end accessibility regressions to production instantly with no quality gate. New components, Docker Compose stack updates, and CMS content changes can all introduce WCAG violations. Government agencies, nonprofits, and universities self-hosting with Coolify face ADA Title II compliance with an April 24, 2026 deadline. PageGuard provides continuous post-deployment monitoring with email alerts when WCAG scores drop.
No — they serve completely different purposes. Coolify is an open-source self-hosted PaaS for deploying and managing web applications on your own servers. PageGuard is an external quality monitoring tool for the front-end output of those deployed applications. Teams using Coolify for self-hosted deployment should add PageGuard to continuously verify WCAG compliance, Core Web Vitals, and SEO quality after each deployment.
