Northflank offers a free tier including Redis (0.1vCPU, 256MB, 4GB disk) as well as PostgreSQL, MongoDB, MinIO and more. Heroku at scale makes little financial sense for many businesses - our pricing is fair so you can scale as and when your infrastructure demands f.e 7GB on Heroku Redis costs $750 vs $72 on Northflank.

Northflank appears to be slightly cheaper than Heroku across everything, but its not really worth the squeeze to save $5-10/mo.
If I ever grow out of Heroku, DO's 1GB RAM for $5/mo is way cheaper. In theory, I could host my own redis for $5/mo at 1GB too. I wouldn't trust myself to self-managed a DB though.
