GetContentGap

A no-auth content gap analysis tool for SaaS founders. Enter your URL and a competitor's — it surfaces the exact keywords and topics they rank for that you don't, ranked by traffic opportunity. Results in under 3 minutes, no signup required.

The problem

SaaS founders know they need content but don't know which content to write first. Existing tools are expensive, slow, and built for agencies — not for founders who want a quick answer and need to act on it today.

What I built

GetContentGap takes two URLs and runs a full analysis pipeline: crawling both sites, querying keyword data from an SEO API, diffing the topic coverage, and using an LLM to summarise the highest-value gaps with suggested angles.

The whole flow is no-auth. A visitor pastes two URLs, the analysis runs in the background, and results appear on-screen. No account, no dashboard, no friction.

Technical highlights

The pipeline runs on serverless functions with streaming output so users see partial results immediately rather than waiting for the full job. LLM summarisation adds context to raw keyword data so the output is actionable, not just a list of numbers.
