I shipped a paid SaaS in 3 days with no user accounts: the billing setup and 3 bugs that bit me
I write a small blog on the side. Every time I picked a topic I hit the same wall: Ahrefs and Semrush are $130+ a month, and even when I had the numbers, "volume 590, difficulty 17" didn't tell me whether to write the post or skip it.

This writer launched Keyword Brief to help others choose blog topics efficiently. They built a tool that takes a keyword and provides a GO / MAYBE / SKIP recommendation, along with Google search volume, difficulty, top 10 page content analysis, and an outline highlighting gaps. Notably, the platform operates without user accounts—no signups, password resets, or user tables.
Payments are processed seamlessly through Lemon Squeezy. The stack includes Next.js on Vercel, DataForSEO for search metrics, cheerio for scraping top-ranking page headings, Claude AI for creating outlines, and Lemon Squeezy subscriptions. A single check costs around $0.10. The author outlines three main bugs they encountered: inactive keys upon first purchase, issues with structured output length limits in Claude’s responses, and the SERP depth metric in DataForSEO not accurately representing organic results.
To resolve these issues, they implemented fixes such as activating keys on first use, removing length constraints on structured outputs, and adjusting the SERP depth filter to focus exclusively on organic results.
