The Developer's Launch Checklist for 2026
Before You Launch
Launching a new website or web app? Here's everything you need to check before going live. This list covers the essentials that developers often forget.
Visual & Social (The First Impression)
1. OG Images
Every page needs a custom Open Graph image. When someone shares your link on Slack, Twitter, or LinkedIn, this is what they see.
Don't: Use a generic screenshot or leave it blank. Do: Use OG Image Generator to create dynamic, branded preview images for every page.
2. Favicon
Provide both favicon.ico (legacy) and favicon.svg (modern, supports dark mode). Don't forget apple-touch-icon.png for iOS.
3. Theme Color
Set for mobile browsers. Match it to your brand color.
SEO Basics
4. Meta Tags
Every page needs unique:
(50-60 characters)(150-160 characters)
5. Sitemap
Generate a sitemap.xml with all your public pages. Submit it to Google Search Console.
6. robots.txt
Allow search engines and AI crawlers to index your public content. Block admin pages, API routes, and authenticated areas.
7. Canonical URLs
Set on every page to prevent duplicate content issues.
AI Search Visibility (New in 2026)
8. AI Crawler Access
Make sure your robots.txt allows:
- GPTBot (ChatGPT)
- PerplexityBot
- ClaudeBot
- Google-Extended
9. Schema Markup
Add JSON-LD structured data:
- Organization on your homepage
- Product on pricing/product pages
- Article on blog posts
- FAQ on help/support pages
10. AI Visibility Audit
Run your site through Geonapse to check your AI search visibility score. It checks 40+ factors including schema, crawlability, content structure, and citation signals.
Performance
11. Core Web Vitals
Test with Lighthouse and aim for:
- LCP (Largest Contentful Paint) < 2.5s
- FID (First Input Delay) < 100ms
- CLS (Cumulative Layout Shift) < 0.1
12. Image Optimization
Use next/image, loading="lazy", and modern formats (WebP/AVIF). Compress everything.
13. Caching Headers
Set appropriate Cache-Control headers. Static assets should be cached aggressively.
Security
14. HTTPS
Non-negotiable. Use Vercel, Cloudflare, or Let's Encrypt for free SSL.
15. Security Headers
Set these headers on all responses:
X-Content-Type-Options: nosniffX-Frame-Options: DENYReferrer-Policy: strict-origin-when-cross-originPermissions-Policy: camera=(), microphone=()

Ready to Launch?
Run through this checklist, fix any gaps, and ship it. Your website only needs to be good enough to launch — you can iterate after you have real users.
The two things most developers skip that have the biggest impact: custom OG images and AI search visibility. Both take less than 10 minutes to set up with the right tools.
