High authority developer tool directories, in short
Rated 70 and above. These are harder to get into, slower to approve, and worth more when they accept you. Submit to them first, because the queue is the long part and everything else can be done while you wait.
High authority backlinks, defined
Domain rating is a third-party score from 0 to 100 estimating the strength of a site's backlink profile. It is logarithmic, so the gap between 70 and 80 is much larger than the gap between 30 and 40, and it says nothing at all about traffic, relevance or whether your listing will ever be seen. This page filters to everything rated 70 and above.
Different tools produce different numbers for the same site: domain rating, domain authority and authority score are separate metrics from separate vendors that happen to look alike. Comparing a figure from one against a threshold from another is a common and entirely avoidable mistake.
By the numbers
These 18 directories have a median rating of DR 73. The strongest is DEV Community at DR 91, the weakest at DR 70. 6 of them accept a submission for nothing, and 3 charge for every listing. 11 pass a dofollow link.
That is 15 points above the median for the full list of 175 directories, which sits at DR 58. By band that is 6 rated 80 or above and 12 rated 60 to 79. 3 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
Chasing the rating and ignoring the fit, which produces links from strong sites in categories nobody browses. Comparing scores across different SEO tools as though they were the same metric. And assuming a high rating means the page your listing sits on will be indexed, which is a separate question and frequently not the case.
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, Twelve Tools, StackShare and Dofollow Tools among them.
Questions people ask
How many are there, and what do they cost?
18 directories match on this page. 6 take a submission for nothing, 9 run a free tier with paid upgrades, and 1 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 a good domain rating for a backlink?
Above 50 is generally considered solid and above 70 strong, but the thresholds matter less than relevance. A rating of 50 in your exact category beats an 80 in a general one.
What are some high-authority sites for backlinks?
Among the directories here, the strongest are SourceForge, DEV Community, Hacker News and Product Hunt, all rated 91 or above and all free to submit to. The table lets you sort by rating to see the rest.
How much does a high-authority backlink cost?
On this list, frequently nothing. The four highest-rated entries accept free submissions. Where sites do charge, the fee reflects their placement and audience rather than the rating itself.
Does a high rating guarantee a good link?
No. Rating measures the site's backlink profile, not whether your listing will be seen or whether the page it sits on will ever be indexed.
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.
