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.

On the roadmap, not shipping
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.
Stop overpaying for a steady fleet.
Reserver is in early access. Join the list and we'll onboard you as capacity opens up. Your first recommendation lands within minutes of connecting.
