Backlink Dirs vs OpenTools

Backlink Dirs is a curated web directory where founders and SEO teams research launch platforms, AI tool lists, and other sites that accept product submissions. Each external listing shows domain rating, estimated monthly visits, category labels, and tags for dofollow status, pricing intent, and audience focus. The homepage search and filters let you narrow by category, tags, and pricing before sorting by recency.

Most backlink spreadsheets go stale because traffic and DR scores are not refreshed beside each URL. Backlink Dirs keeps those metrics on every card and also runs its own product directory with free, Pro, subscription, and weekly sponsor tiers. The site promotes a Submit CLI with agent skills that target faster publishing across multiple external directories, with unlimited submissions unlocked on the monthly plan.

Indie founders, SEO specialists, and growth agencies can use Backlink Dirs to plan outreach and manage their own listing in one place. Free product submissions require a reciprocal backlink to Backlink Dirs and ship within 72 hours, while Pro and subscription tiers drop that requirement and add faster review paths.

The catalog spans nine paginated browse pages of directories, from high-traffic launch sites to niche AI and developer lists. Backlink Dirs itself reports DR 51 and about 1.7k monthly visits on the homepage header, giving you a quick read on the platform's own authority before you commit to a paid listing.

OpenTools runs a searchable directory for the AI builder stack, listing 2,500+ tools alongside MCP servers, LLM comparisons, expert agencies, and curated guides. The homepage centers on an Ask AI bar where you type plain questions like comparing Claude and GPT-4 or finding database MCP servers. Listings show upvotes, pricing labels, and category tags so you can scan trends without opening every vendor site. The site reports 782K+ monthly visitors and has supported 120+ tool launches.

Most AI directories stop at SaaS listings. OpenTools stacks tools with a 57-service MCP directory, a 100+ model benchmark hub, nine listed expert agencies, and a Resources library with 138 guides across 66 tools. That breadth targets builders who need models, connectors, and implementation help in one place rather than hopping between niche lists.

The Knowledge Hub adds news, blog posts, and optional The AI Edge newsletter for weekly workflows. Founders can submit tools for a four-day homepage feature with social posts on Twitter (24K followers) and LinkedIn (5K followers). Marketing teams and product managers use it to scout competitors, while developers lean on MCP and model pages before wiring agents.
