Free means free to list: no listing fee and no "expedited review" you have to buy to get in. Several of these sell something on top, and we do too. Of the 192 directories in our catalogue, 88 qualify. These are twenty of them, and they work the same for a SaaS as for a mobile app.
We are first. It is our list, our DR is 40, and SourceForge below us is 92. The order is ours; the numbers are not. If you only take one thing from this page, take the numbers.

Domain Ratings are the source catalogue's, collected on 4 September 2026, and they move. What DR does and does not tell you is in its own guide.
Read the Link column before the DR column
Sixteen of these are rated DR 80 or above, which looks like a great afternoon. It is a good afternoon, not a great one, and the reason is in the fourth column rather than the third.
findly.tools is nofollow. It is still worth doing, because a nofollow link on a directory people actually browse sends real visitors and Google treats nofollow as a hint rather than an instruction now. But it will not move your rankings, and any list presenting it as a DR 80 backlink is selling you something.
The rest are listed as followed. That is the catalogue's claim rather than something we verified on all twenty, so check the one you care about before building a plan on it.
Three of these are not really directories
Hacker News is a community with a launch slot. Posting a Show HN is free and, on a good day, outperforms this entire table combined. It is also the one that punishes a bad post hardest. How to launch on Hacker News covers what a good one looks like.
Indiegogo is a crowdfunding platform. It is on the list because it is DR 90 and free, and it is only relevant if you have something to crowdfund.
Crunchbase is a company database. You are creating a company profile, not a product listing, and it is worth doing once for reasons that have nothing to do with this list.
The order to work through them
- G2, Crunchbase, SourceForge, DevPost. High DR, followed, genuinely browsed. Half a day.
- The B2B review sites if you sell B2B: Trustradius, Good Firms, Proven Expert. Skip entirely if you do not.
- SaaSHub, StackShare, findly.tools. Smaller, but the traffic is developers looking for tools, which is worth more per visitor than a high-DR general directory.
- Hacker News, once, when you actually have something to show.
- The rest of the 88 free ones, in the full list, if you have an afternoon spare.
Write the description once
All twenty ask for roughly the same thing: a name, a URL, a category and 150 to 210 characters. Write those characters properly one time, then keep the first sentence and adapt the rest to each site. It is still the single biggest saving available on this whole exercise, and how to write an app description is the version worth starting from.
And number one
Ours is DR 52, which is the smallest number in the table. What it has instead: listing is free on every tier, for any number of apps, and every approved app gets its own page with a followed link.
One condition, stated up front: a free listing launches once our badge is on your app's site. If you would rather not add it, a paid launch skips it. What that costs, and what it does not buy, is on the pricing page.
Submit it here. It takes about five minutes, and if you would rather your coding agent did it, that works too.
