Building a landing page / marketing site with Zod? Let us review it.
Expert code review for landing page / marketing sites built with Zod. We fix Zod-specific security gaps, optimize performance, and handle deployment. From $19.
Common Zod issues we find
Real problems from Zod codebases we've reviewed.
Incomplete schema validation
Zod schemas that validate the happy path but miss edge cases like empty strings, negative numbers, or overly long inputs that break downstream logic.
Schema-data mismatch
Zod schemas that don't match the actual API response or database shape, causing runtime parse errors that crash the application.
Missing transform and refinement
Schemas that accept raw input without transforming (trimming strings, normalizing emails) or refining (custom business rules), leading to dirty data in the database.
No error message customization
Default Zod error messages exposed directly to users, showing technical details like 'Expected string, received number' instead of user-friendly messages.
Landing Page / Marketing Site challenges to solve
Key landing page / marketing site concerns that AI-generated code often misses.
Page speed
Landing pages must load in under 2 seconds. AI tools generate bloated CSS, unoptimized images, and unnecessary JavaScript that slow loading. A 1-second delay in load time reduces conversions by 7%.
SEO fundamentals
Missing meta descriptions, incorrect heading hierarchy, no Open Graph tags, no structured data, and no sitemap. AI tools build the visible content but skip the invisible SEO infrastructure.
Form handling
Your contact form, waitlist signup, or demo request form must work flawlessly. AI-generated forms often lack validation, error messages, success confirmations, and backend integration.
Mobile responsiveness
Over 60% of traffic is mobile. AI-generated layouts sometimes break on small screens — overlapping elements, unreadable text, and inaccessible buttons. Every pixel matters for conversion.
