I use Outline as our internal knowledge base, and it serves as a replacement for Notion for me. I love the speed, and the self-hosted option is a big plus. Sharing and custom domains are particularly great because I can share my personal notes with them. It works very fast and can even function as a PWA, making it my truly knowledge base. The initial setup was really easy and it worked well just in 10 minutes. Review collected by and hosted on G2.com.

Unfortunately, it all comes to the S3 integration, I'd like to see it work with Cloudflare R2 or similar, cheaper object storages since I'd like to store as much data as I can there, but S3 egress costs are way too much for personal use. They need to add support for more 3rd party providers besides S3 and make storage options more flexible. Review collected by and hosted on G2.com.
