DOGimg is a utility product for generating Open Graph images directly from a webpage URL. It helps creators and developers quickly produce social preview images without manual design work.
Key Features
URL-based Generation: Create OG images by passing a target URL
API-first Usage: Direct endpoint integration for automated workflows
Meta Data Extraction: Uses page title, description, and favicon as generation inputs
Share-ready Output: Designed for social link previews and SEO snippets
Simple Local Run: Works locally with standard Next.js development setup
Technical Challenges & Solutions
Challenge 1: Reliable source extraction
Implemented HTML parsing to consistently collect key metadata from arbitrary webpages.
Challenge 2: Render quality in API responses
Used @vercel/og-based rendering so generated images remain fast and visually consistent.
Challenge 3: Practical integration path
Kept the API contract simple (/api/og?url=...) so it can be plugged into existing sites with minimal effort.
What I Learned
Building focused API tools on top of Next.js route handlers
Converting page metadata into visual output pipelines
Designing utility products with low integration friction
Balancing simplicity and output quality for SEO-focused tooling
Impact
DOGimg reduces the effort required to produce social preview assets and makes OG-image workflows easier to automate.
