Features
Everything between running and reserved.
See what's running, know what you own, and get a priced recommendation for every gap. Buying still happens in the AWS console, and this page says exactly where that line sits today.

Know exactly what's running, and what covers it.
Full fleet inventory
Reserver scans every connected account for running RDS instances, ElastiCache clusters, and EC2 instances. Each one carries its class, region, AZ, engine, and platform.
Reservation ledger
Every reservation you own sits in one ledger: term, payment option, expiry date, and whether anything is actually using it.
Coverage map
Coverage by service, region, and account, in one view. See what's reserved, what's on-demand, and what's about to expire.
Coverage drift detection
Reserver compares each scan against the one before it. An instance that loses its match shows up right away, not weeks later at the next quarterly review.
Expiry radar
Reserver tracks every reservation's end date and flags a term that expires soon, before it lapses and the bill rises.
Idle-reservation detection
A reservation with nothing using it still costs money. Reserver flags it, so you can move it to a different instance or let it lapse on purpose.
Utilization sampling
Reserver samples trailing CPU, network, and connection metrics from CloudWatch for every instance, so a recommendation never assumes activity it can't see.
Decide
Recommendations that show their work.
Concrete purchase proposals
Each recommendation is a line item: instance class, term, payment option, break-even date, and dollars saved per year, for any instance class Reserver covers.
Term & payment comparison
Compare a 1-year term against a 3-year term, and no, partial, or all upfront payment, side by side for your own fleet.
Rightsizing caution
Reserver flags a recommendation when every instance behind it peaked below the CPU threshold over the trailing window. The flag is a caution, and the recommendation still shows. Missing utilization data is never read as idle.
Old-generation detection
Reserver flags a recommendation built on a superseded instance family and names the current-generation family that replaces it. Flag a family as one you plan to leave, and Reserver stops proposing a term on it.
Act
Buy in the AWS console today. Buying itself is next.
1-click connect
An owner or admin clicks Connect, accepts a pre-filled AWS quick-create stack, and a read-only role exists. No key, no password, and nothing hand-typed.
One-click purchasingbuilding · M4
Accept a recommendation, and Reserver will execute it through the AWS reservation purchase APIs: RDS, ElastiCache, and EC2, from one place.
Renewal autopilotbuilding · M5
Set the policy once. When a reservation nears expiry, Reserver will re-buy it on the same or updated terms.
Scheduled purchasesbuilding · M5
Line a purchase up with your budget cycle: the first of the quarter, the start of the fiscal year, or the day after the board meeting.
Age-based rulesbuilding · M5
Set a rule once: any instance older than 90 days gets reserved. Most fleets keep an instance once it survives that long.
Approvals & audit trailbuilding · M4
An automated purchase will be able to need sign-off first. Every purchase, manual or automatic, will log who approved it, what it cost, and what it saves.
Notify
Set up your team and an email channel today. Alerts come next.
Team roles and invites
Invite teammates and set a role for each one: owner, admin, or member. A member reads coverage and recommendations and changes nothing.
Email channel registration
Register and verify an email channel today. It cannot send an alert yet.
Read-only access
On every plan, Reserver only reads your account. Nothing buys on your behalf today.
Email, Slack, SMS deliverybuilding · M3
A new recommendation, an expiring term, or a weekly digest will reach your channel: email, Slack, or SMS.
Digest, not noisebuilding · M3
A weekly summary of coverage and savings will land in one message, tuned so the one urgent alert still stands out.
Every fleet size
Unlimited reservations, at every size.
Inventory, matching, the coverage map, drift detection, the expiry radar, recommendations, old-generation flags, and rightsizing caution, with unlimited reservations. Watch costs $0 and covers 1 AWS account.
Everything in Watch, plus utilization sampling, team roles, and an email channel. Autopilot costs $149 a month and covers up to 5 AWS accounts.
Everything in Autopilot, plus priority support from a named human. One stack per account today. Scale costs $499 a month and covers unlimited AWS accounts.
Why the expiry radar matters
What one missed renewal costs.
These figures are illustrative, for one sample instance. A reservation that lapses for six hours costs about $3.36 in on-demand overage. Left for three days, the same lapse costs about $40.32. A fleet of ten instances pays that overage ten times over. Watch costs $0 and flags an expiring term on the expiry radar before it lapses. The default six-hour scan catches a slip on the same day. A quarterly review would find it weeks later. See the full math on the renewal cost calculator.
Questions
Features, straight answers.
What works today, and what's on the roadmap?
Fleet inventory, coverage mapping, coverage drift, and priced recommendations are live today. Buying a reservation, renewal autopilot, scheduled purchases, and age-based rules are still on the roadmap.
Does every plan get every live feature?
No. Every plan gets the core live features: inventory, matching, the coverage map, drift detection, the expiry radar, and priced recommendations. The two paid plans add utilization sampling, team roles and invites, and an email channel. The top plan also adds priority support.
Does Reserver buy anything today?
Not today. You buy every recommendation yourself, in the AWS console. One-click purchasing is on the roadmap.
Is there a reservation limit?
No. Every plan covers unlimited reservations. The price never depends on how many reservations you manage.
Which AWS services does Reserver cover?
RDS, ElastiCache, and EC2.
Does Reserver cover Savings Plans, or another cloud provider?
Not yet. AWS Savings Plans are on the roadmap. Reserver does not cover another cloud provider today.
Covered today: Amazon RDS · Amazon ElastiCache · Amazon EC2. More on the roadmap →
