Question 1

What is Open Source Alternatives?

Accepted Answer

Open Source Alternatives is a curated directory of open source tools that replace popular paid software. We manually review every listing to confirm it is genuinely open source, actively maintained, and self-hostable. The directory covers categories from project management and analytics to CRM, email, and developer tools.

Question 2

Is everything in the directory actually open source?

Accepted Answer

Yes. Every tool in the directory has a public GitHub repository and an open source license. We verify the license (MIT, Apache, AGPL, or GPL) before publishing a listing. We do not accept tools without a verifiable open source license.

Question 3

How do you decide which tools to include?

Accepted Answer

We evaluate each submission against four criteria before publishing. The criteria are active maintenance, a clear open source license, a working self-hosted installation path, and genuine feature parity with the paid tool it replaces. All four must pass our manual review.

Question 4

Can I find a replacement for a specific paid tool I use?

Accepted Answer

Yes. Each listing includes a field showing which paid software it replaces. You can search by the paid tool name or browse by category to find verified alternatives. The alternative-to pages list the top replacements for the most common paid tools.

Question 5

Are these tools free to use?

Accepted Answer

Self-hosted versions are free forever with no usage limits. Some tools also offer managed cloud hosting with paid tiers, but the self-hosted option remains free under the open source license. We note the license type on every listing so you know exactly what you are getting.

Question 6

What does GitHub-verified mean on a listing?

Accepted Answer

GitHub-verified means the listing links to a confirmed public GitHub repository. We pull stars, forks, and last push date from that repository to give you a live signal of community activity and maintenance health. We do not publish listings without a GitHub repository.

Question 7

How do I list my open source tool?

Accepted Answer

Click List your tool in the navigation, fill in the submission form, and select a listing plan. Free listings are reviewed within 72 hours. Paid listings get priority review, featured placement in search results, and promotion to our subscriber list. Your tool must have a public GitHub repository and an open source license to qualify.

Question 8

How current is the directory?

Accepted Answer

We add new tools weekly and sync GitHub metrics on a rolling schedule. Each listing shows the date it was added to the directory and the last GitHub sync date. If you notice a listing with outdated information, contact us at support@opensourcealternatives.to and we will update it.
