These tools help you verify that your app’s infrastructure is production-ready after deploying with Nometria or any hosting provider.

​
SSL Checker

Verifies your TLS certificate is valid and correctly configured. Checks:
  • Certificate is issued by a trusted CA
  • Not expired (warns if expiring within 30 days)
  • Domain matches the certificate (including wildcards)
  • Intermediate certificate chain is complete (incomplete chains cause mobile browser errors)
  • HTTPS redirect is in place (HTTP → HTTPS)
  • HSTS header is present
Usage: Enter your domain → instant results. No registration needed.

​
DNS Propagation Checker

Checks how your DNS records have propagated across global resolvers. Enter a domain and record type (A, CNAME, MX, TXT, NS) and see the response from resolvers in:
  • US (Cloudflare 1.1.1.1, Google 8.8.8.8)
  • Europe (Frankfurt, Amsterdam)
  • Asia Pacific (Singapore, Tokyo)
  • South America (São Paulo)
Useful after adding a custom domain in Nometria — you can confirm propagation before testing your live URL.

​
DNS Setup Guide

Enter your domain registrar (Cloudflare, Namecheap, GoDaddy, Squarespace, Wix, etc.) and your target hosting (Nometria, Vercel, Netlify, AWS) — get the exact steps and record values you need to add, specific to your registrar’s interface.

​
Page Speed Test

Runs a Lighthouse audit against your URL and returns:
  • Performance score (0–100)
  • Core Web Vitals:
    • LCP (Largest Contentful Paint) — target: < 2.5s
    • CLS (Cumulative Layout Shift) — target: < 0.1
    • FID/INP (Interaction to Next Paint) — target: < 200ms
  • Opportunities — specific recommendations to improve score
  • Diagnostics — unused JavaScript, uncompressed images, render-blocking resources
Common issues in vibe-coded apps:
  • Large uncompressed images (use the image pipeline to fix)
  • No code splitting (all JS loaded at once)
  • Missing lazy loading on below-the-fold images

​
Uptime Monitor

A one-time uptime check — not a continuous monitoring service. Enter a URL and get:
  • Current status (up/down)
  • Response time
  • HTTP status code
  • Response headers
  • Time to first byte (TTFB)
For continuous monitoring, use a dedicated service like Better Uptime, UptimeRobot, or Checkly.

​
Dockerfile Generator

Generate a production-ready Dockerfile for your stack: Supported stacks:
  • React + Vite (nginx static serving)
  • Next.js (Node.js standalone mode)
  • Node.js + Express
  • Python + FastAPI / Flask / Django
  • Go
  • Ruby on Rails
Example output for React + Vite: 
FROM node:20-alpine AS builder
WORKDIR /app
COPY package*.json ./
RUN npm ci
COPY . .
RUN npm run build

FROM nginx:alpine
COPY --from=builder /app/dist /usr/share/nginx/html
COPY nginx.conf /etc/nginx/conf.d/default.conf
EXPOSE 80
CMD ["nginx", "-g", "daemon off;"]

​
Environment Variable Validator

Check that all environment variables your app expects are actually set. How it works:
  1. Paste your .env.example file (which lists expected variable names)
  2. Paste your actual .env or environment variable list
  3. Get a diff — missing variables, extra variables, and type mismatches (empty string vs not set)
Useful before deploying to catch missing secrets that would cause runtime errors.
