Coverage
Three services. One coverage map.
Reserved Instances work differently on each AWS service Reserver covers — what has to match, what can flex, and where the money actually leaks. Pick yours.

AWS-only, RI-only today.
Reserver covers AWS Reserved Instances today — RDS, ElastiCache, and EC2. Everything below is on the list and not yet shipped; we'd rather say so than imply coverage we don't have.
Savings Plans
Compute and EC2 Instance Savings Plans are a different commitment shape (spend-based, not instance-based) — not yet supported.
Amazon OpenSearch Reserved Instances
Another AWS reservation type, not yet scanned or matched.
Amazon Redshift Reserved Nodes
Same idea, different service — on the list, not shipped.
Other cloud providers
Reserver is AWS-only today. Azure and GCP reservation equivalents are not supported.
