AI and developer tool directories, in short
AI is the most crowded corner of this list and the one with the most search demand behind it, so the good directories are strict and the bad ones are wall-to-wall affiliate links. Check that a directory still gets traffic before you spend an evening writing a submission for it.
What counts as an AI tool directory
An AI tool directory is a curated index of software with a machine-learning component, organised so someone looking for, say, a transcription tool can find six of them side by side. The good ones moderate submissions, write or edit the descriptions themselves, and keep category pages that rank. The rest are scraped lists with an affiliate link on every row, and they are easy to spot: no editorial voice, hundreds of entries added in a single week, and no traffic worth measuring.
The distinction matters more here than in any other category on this list. AI has attracted more directory launches in the last two years than the previous decade produced in total, and a large share of them exist to collect submissions rather than to serve readers. A listing on one of those costs you an evening and returns a link on a page that has never been crawled twice.
By the numbers
These 23 directories have a median rating of DR 70. The strongest is DEV Community at DR 91, the weakest at DR 10. 10 of them accept a submission for nothing, and 5 charge for every listing. 13 pass a dofollow link.
That is 12 points above the median for the full list of 175 directories, which sits at DR 58. By band that is 4 rated 80 or above, 11 rated 60 to 79, 3 rated 40 to 59 and 5 rated below 40. 5 of them have no traffic estimate at all, which usually means too little to measure rather than none.
What a listing actually gets you
A listing here converts at rates the general directories cannot approach, because everyone reading it is already looking for what you built. Ten visitors from a developer directory will often outperform a thousand from a launch platform on any metric you care about after the first week.
There is a second effect worth knowing about. Developer directories are heavily represented in the training and retrieval data behind coding assistants, so a listing increasingly determines whether your tool gets suggested when someone asks an AI how to solve the problem you solve.
Submitting without wasting the evening
Link the documentation, not the marketing page. Developers arriving from these sites want to see the install command, the API surface and the licence before they will consider anything else. An honest limitations section converts better here than a feature list, because the audience will find the limitations anyway. If your tool is open source, say so prominently: it is the single strongest signal on most of these sites.
Common mistakes
The three that cost people the most: submitting a landing page with no product behind it, which gets rejected and makes the second attempt harder; writing a new description for every form, so the same tool appears with five different positionings and none of them stick; and submitting to forty directories in a weekend because the list was there, which produces a link pattern that looks exactly like what it is. Pick the ones that cover your category, write one description, and spread the work out.
Where to start
By audience size, the biggest here are Hacker News, DEV Community and Product Hunt, led by 13.53M visits a month. The highest-rated one you can use without paying is DEV Community at DR 91. 4 approve quickly, Dofollow Tools, SideProjectors and Productivity Directory among them.
Questions people ask
How many are there, and what do they cost?
23 directories match on this page. 10 take a submission for nothing, 8 run a free tier with paid upgrades, and 3 charge for every listing.
Which should I submit to first?
By rating, DEV Community (DR 91), Hacker News (DR 91) and Product Hunt (DR 91). By audience, Hacker News is the largest at 13.53M visits a month. Relevance beats both: a directory that actually covers what you built will do more than a stronger one that does not.
What is an AI tool directory?
A curated index of AI software, usually organised by what the tool does rather than which model it runs on. Most let you filter by category and pricing, and the better ones write their own descriptions instead of reprinting your marketing copy.
What is the best AI tool directory?
There is no single best one, but the table above orders them by the two things that matter: how strong the domain is and how many people actually visit. There's An AI For That and Dang.ai are the two most people start with, and Product Hunt still sends more launch-day traffic than any AI-specific site.
Are free AI directories worth submitting to?
The ones with traffic are. The ones without are a link on a page nobody visits, which is worth roughly nothing whatever the domain rating says. Sort by the traffic column before you sort by anything else.
Why do developer directories send so little traffic?
Because developers do not browse directories, they search for a specific problem and land on one page. The visit counts are low and the conversion rates are not comparable to anything else on this list.
Does open source help?
Considerably. Several of these directories either prioritise open-source entries or have a dedicated section for them, and the audience treats a public repository as evidence that the tool is real.
Should I submit a library or just the product?
Both, if they are genuinely separate. A library and the hosted service built on it are two different things to two different readers, and most directories are happy to list them separately.
Every figure quoted above is read off the table on this page, so it moves as the list does. Domain rating and traffic are third-party estimates captured in September 2026: useful for ordering a shortlist, not precise figures.
