Appwrite
Appwrite offers flexible pricing plans to match different needs and project sizes.
The Free plan costs nothing and includes 5GB of bandwidth, 2GB storage, 750,000 function executions, and support for 75,000 monthly active users. You get one database, one storage bucket, and five functions per project, with a limit of two projects. This plan never pauses and works great for small apps and learning projects.
The Pro plan starts at $25 per month and provides 2TB bandwidth, 150GB storage, 3.5 million executions, and 200,000 monthly active users. Pro users get unlimited databases, buckets, and functions, plus daily backups, email support, and organization roles.
The Enterprise plan offers custom pricing for larger teams. It includes everything in Pro plus dedicated support, higher limits, custom backup policies, single sign-on, activity logs, and options to bring your own cloud infrastructure. Enterprise customers can also get volume discounts and uptime guarantees.
SlateDB
SlateDB is completely free and open source under the Apache 2.0 license. There are no licensing costs, subscription fees, or usage charges for the database software itself.
However, you will pay for the cloud storage you use. Costs depend on your chosen provider and usage patterns. For example, Amazon S3 typically charges around $0.023 per gigabyte per month for standard storage, plus small fees for data transfers and API requests.
SlateDB helps reduce these costs through smart batching of write operations. Instead of making an API call for every single write, it groups them together, significantly lowering expenses compared to writing directly to object storage.
The software is maintained by an active open-source community with regular updates and improvements. Being part of the Commonhaus Foundation ensures long-term project sustainability and governance.
