# Lin-k.to > Free curated database of 800+ SaaS directories and 75+ startup launch sites to help indie makers and SaaS founders build backlinks, boost organic traffic, and grow brand visibility — completely free. Lin-k.to is a one-page landing site where anyone can download a free, regularly updated spreadsheet listing 800+ SaaS and software directories alongside 75+ startup launch platforms. Every entry is ranked by Domain Authority (DA) so founders know exactly which submissions deliver the highest SEO impact. A special "Priority Sites" column highlights the directories with the greatest real-world effect on rankings and referral traffic. The April 2026 edition added new high-DA sites, removed obsolete ones, and introduced the Priority Sites column. The list is trusted by 990+ indie makers and "vibe coders." The product is free and downloaded via Gumroad. No subscription or payment is required. ## Key sections on the page - **Hero**: Headline, social proof badge ("Trusted by 990+ indie makers & vibe coders"), a preview screenshot of the spreadsheet, and the primary download CTA. - **The Boost Engine**: Three benefit cards — Boost Organic Traffic, Build High-Quality Backlinks, Maximize Brand Exposure — explaining why submitting to directories matters. - **Social Proof**: Embedded tweet from @illyism on the real value of backlinks. - **Mega CTA**: High-contrast final call-to-action encouraging visitors to download the free list. - **Sponsors**: Logos and links for sponsors who support the project. ## Important links - Homepage: https://lin-k.to/ - Download (Gumroad): https://r4fken.gumroad.com/l/SaaSList - OG image: https://lin-k.to/opengraph.jpg - Sitemap: https://lin-k.to/sitemap.xml - LLM summary (this file): https://lin-k.to/llms.txt - LLM full detail: https://lin-k.to/llms-full.txt ## Who this is for Indie hackers, SaaS founders, solo entrepreneurs, and "vibe coders" who want to maximise the reach of a new or existing product without spending money on paid advertising.
