Turn monthly recurring revenue into annual recurring revenue (ARR = MRR x 12), with ARPU when the customer count is given and the months to $100k, $1M and $10M ARR at a monthly growth rate. Count annual plans at their yearly price divided by 12 and leave one-time fees out of MRR. Full calculator: https://saascity.io/free-tools/arr-calculator

Explain how ARR moved over a period: ending ARR = starting ARR + new + expansion - contraction - churned.

Check whether a directory listing page links to your site and whether that link is followed. Reads the page's static HTML and reports every anchor pointing at your domain with its rel (nofollow, ugc, sponsored), hidden links, links that only go through the directory's own redirect, and page-level noindex, nofollow and canonical. Use it after submitting to directories to see which listings went live and which ones pass a dofollow link.

Check whether the SaaSCity badge is live on a site. Reads the given URL and, for a deep page, the site homepage too, rendering JavaScript if needed. Free listings require a badge and use nofollow website links.

Audit a product homepage before launching it: HTTPS, noindex, title and meta description, og:image (fetched to confirm it loads), X card, favicon, canonical, mobile viewport, h1, JSON-LD, robots.txt, sitemap, parked or 404 pages, response time, and whether the page is empty without JavaScript. Returns a 0-100 score, a verdict and a fix for every problem. Reads the static HTML the way directory scrapers and link-preview bots do.

Other SaaSCity listings in the same category as a given listing, most upvoted first. Useful for competitor research and positioning.

Filter 1,667 startup, SaaS and AI directories by category, minimum Ahrefs DR, link type (dofollow/nofollow), price and badge-swap requirement. Returns submit URLs. Link type and price are "unknown" where nobody has verified them yet - treat those as unverified, not as free or dofollow.

Look up one directory by domain or URL: Ahrefs DR, dofollow or nofollow, price, whether it wants a badge swap, the submit URL, and a human verdict where one exists. Use it to vet a directory before paying for a listing.
