Open source software for business, reviewed
Cut licence costs, keep your data on your own servers and change the software when you need to. We compare open source options on licence terms, self-hosting effort and what the paid editions hold back, and test the popular ones on our own server.
Why businesses choose open source
Lower software cost
No per-seat licence fees for the open source edition. You pay for hosting and the time to run it.
Your data stays with you
Self-hosting keeps customer data on servers you control, which helps with privacy and data residency rules.
Change what you need
The code is open, so your team can fix, extend or integrate it without waiting on a vendor's roadmap.
No lock-in
If a project changes direction, you can keep running your version or move to a community fork.
The trade-off is that you run it: updates, backups and security are on your team, or on a managed host.
How we evaluate
No vendor influences these pages. A vendor can pay for a Featured placement, labelled Sponsored, which never changes a rank or a review.
- What qualifies
- Open source or clearly labelled source-available software that a business can self-host, with a commit or release in the last 12 months and documented installation.
- Where we look
- GitHub, the pages that rank for each category, so both established and newer projects are considered.
- How we rank
- Fit for business and technical teams: maintenance activity, self-hosting effort, licence terms, and which features the paid editions lock. Payment never changes a ranking.
- Where the data comes from
- Stars, releases, contributors and licences come from the GitHub. Editions, pricing and requirements come from each software's own docs.
- Hands-on testing
- We install two or three projects per category on a cloud Ubuntu 24.04 server (2 vCPU, 4 GB RAM) with Docker, and record install time and idle memory.
