Open Source Company Stack

Putting together a list of software for working with software based companies.

Focus is on open source licensing, while also looking at privacy preserving issues.

Open Source Stash has a much larger list, including desktop apps and client software.


Plausible Analytics

AGPL licensed. They recently made some changes on how they support the self hosted version - twice a year long term releases.

Cloud version starts at $6/month for unlimited websites Plausible Analytics | Simple, privacy-friendly alternative to Google Analytics


Simple and privacy focused web analytics. Fully hosted, $14/month for unlimited websites.

Originally started as a #golang based open source project that could be self hosted. With this hosted version, which is not open source, it perhaps should not be on this list.
