I have tried to figure out what the real difference is between CE and PRO Version, sure the Cluster and HA makes sense, but why does the CE not have full text files search ?
There will only be 3 that will use Seafil, so in theory I can install the Pro version, and I would not hesitate to pay thr $100 a year if I need a 4-5th user
What else is in the pro version that is not in CE ?
The Seafile Professional Edition (Pro) includes several enterprise-focused features that are not available in the Community Edition (CE). Here are the primary differences:
1. Full-Text Search
As you noted, full-text search is a Pro-only feature. It uses Elasticsearch to index and search not only filenames but also the content of files (Office, PDF, Markdown, Text, etc.). This requires additional system resources (minimum 4GB RAM) which is why it’s excluded from the lightweight CE version.
Pro supports manual and automatic file locking. When a user opens an Office file on their desktop, Seafile can automatically lock it to prevent other users from creating sync conflicts.
Pro allows you to use cloud storage backends like Amazon S3, Ceph, or OpenStack Swift. CE is limited to local storage or network-attached storage (NAS) via file system mounting.
5. High Availability and Clustering
For larger deployments, Pro supports clustering and high-availability setups to ensure the service remains online even if one server fails.
6. Fine-grained Permissions
Pro includes advanced permission settings, such as:
Invisible Permissions: Hide specific sub-folders from users who shouldn’t see them.
Online Read-Write: Restrict users to only editing files through the web interface (OnlyOffice/Collabora) without downloading them.
Recommendation
Since you only have 3 users, you can actually use the Seafile Professional Edition for free. Seafile offers a free license for up to 3 users with all Pro features included. This allows you to benefit from full-text search and file locking without any cost until you need to add a 4th user.
