What We Check Before a Listing Goes Live

Every submission is reviewed before it goes live. For open source projects, these are the things that decide it.

1. 1 The repository is public and has a license file.
2. 2 There are install instructions a stranger can follow, Docker or otherwise.
3. 3 The project has had commits in the last year, or says clearly that it is finished and stable.
4. 4 If there is a hosted paid version, the site says what the free self-hosted one includes.

Write a Listing People Act On

We write the listing from your site, so these land best when your site says them too.

• Say which product you replace. "A self-hosted alternative to Notion" is the phrase people actually search.
• Put the minimum hardware or the one-line Docker command in your README. We can quote it in the listing.
• Name the license. Some teams can only use certain ones.
• Mention how you are funded, whether that is sponsors, a cloud plan or a company. It answers the "will this be around next year" question.

What It Costs

Payment buys speed and placement. It never buys a better review or a higher score.

Where Else to Launch

No single directory makes a launch. These are the places makers of open source projects get real users from.

GitHub

Topics, a good README and a release with notes are your real launch.

r/selfhosted

The most engaged audience for self-hosted software anywhere. Read the rules and post as the maker.

Show HN on Hacker News

Open source launches do well there, especially with a clear reason the project exists.

Awesome lists

Awesome-selfhosted and the lists for your language send visitors for years.

Common Questions

Is listing an open source project free?

Yes. A free listing needs a small nofollow link back to Tool Index, which can go in your README or on your project site.

Do you list projects without a website?

Yes, as long as the repository explains what the project does and how to run it.

What if I also sell a hosted version?

That is common and fine. The listing covers both, and says which features are in which.

How do I mark my project as self-hosted?

Say so in your submission. Open source and self-hosted are tags here, and your listing carries them.
