SimilarLabs
SimilarLabs runs a daily launch board and searchable catalog for new AI tools, SaaS apps, and developer products. Visitors browse date-grouped launches, upvote favorites, and explore 3,731+ listings spread across twelve AI-focused categories from coding to agents.
Most product directories fold promotion into a single paid bundle. SimilarLabs splits the workflow: you pick one of three submission routes (free review, free backlink swap, or $9.99 instant publish), then buy side-rail promotion separately if you want one of ten numbered slots beside its marketing pages.
The site publishes editorial comparison guides, a Hall of Fame for top-voted launches, and localized versions in six languages. Makers get product pages with screenshots and category tags; buyers use the feed to spot tools on the day they ship.
Indie builders, SaaS founders, and growth marketers submit for backlinks or traffic, while researchers hunt early launches before they hit larger directories. Browsing and upvoting stay free; only listing upgrades and fixed-slot promotion carry fees.

Free browsing and upvoting make it easy to scout new AI tools without signing up.
Three submission routes let makers trade speed, badges, and backlink count instead of forcing one bundle.
Side-rail promotion sells exact numbered slots, so advertisers know which position they are buying.

Side-rail promotion slots are separate from listing fees and expire when the paid run ends.
Free and backlink submissions wait up to seven days for manual review.
