The cost graphs and the proposals for reducing costs.

The reviews and the cost savings plan also I am able to see the cost of all my accounts in a single portal which makes it even easier

What I like best about CloudKeeper is the combination of useful AWS cost visibility and proactive support. The team regularly helps us identify unexpected changes in cloud spend and provides practical recommendations for optimisation, rather than simply reporting on costs. CK Lens is also useful for drilling into spend and managing cost allocation in a way that makes it easier to understand where our AWS budget is going. The support team has been particularly valuable. On one occasion they took ownership of an unexpected AWS billing issue, worked directly with AWS on our behalf, followed it through over several weeks and ultimately secured a full adjustment of the charges. We've also benefited from more in-depth optimisation reviews of some of our larger AWS workloads, with specific technical recommendations around architecture, scaling and different AWS services. That combination of tooling, proactive monitoring and access to knowledgeable people is probably where we've seen the most value.
