The spike isn't the hard part. The investigation is.

Every cloud cost tool will show you a line going up. That part is solved, and has been for years. Connect your accounts, get a chart, watch the total.

The expensive part isn’t the chart. It’s the forty minutes after it.

Spend jumped 18% on Tuesday. Now someone has to open the deploy log and work out what shipped. Ask in Slack whether anyone changed an instance type. Check whether an incident on Monday night left something scaled up that nobody scaled back down. Look in Salesforce to see whether a big customer onboarded and this is simply what growth costs. Four different systems, none of which talk to the cost data, all to answer one question your dashboard raised and then declined to address.

That gap — between the number moved and here’s what moved it — is the thing Plutus is built to close.

The chart already knows

Plutus annotates every cost chart with the things that actually happened alongside the spend. GitHub releases and merged PRs. PagerDuty incidents triggering and resolving. Jira fix versions going out. Vercel production deploys. Linear issues. Sentry errors first appearing. Salesforce customers onboarding and churning. Stripe subscriptions starting and cancelling.

So Tuesday’s 18% isn’t a mystery to go solve. It’s a spike with a release marker sitting directly underneath it, and the answer arrives at the same moment as the question.

The business events matter as much as the operational ones, and they’re the half most tooling ignores entirely. “Spend is up 30% this quarter” is alarming on its own and completely unremarkable next to the four enterprise customers who onboarded in the same window. Cost data without the business context behind it produces a lot of fire drills about numbers that were supposed to go up.

Everything you pay for, in one place

The overlay only works if the spend underneath it is complete. Plutus pulls AWS, GCP and Azure alongside OpenAI, Anthropic, Snowflake, Databricks, MongoDB Atlas, Datadog, Vercel, Cloudflare, Neon, GitHub Actions and more. Cloud, AI and SaaS in a single view rather than three tabs you mentally add together.

For anything without a dedicated connector, there’s a FOCUS-spec importer: point Plutus at a FOCUS-conformant export from any provider and it parses it directly. One integration covering the long tail: Temporal, Confluent, Modal, PlanetScale, Fastly, Linode. No waiting for each to be built.

Ask it in plain language

Plutus runs an MCP server, so you can point Claude, ChatGPT or Gemini at a read-only key and ask what you’re spending without learning a dashboard first. “What drove the increase in AI costs last month?” is a reasonable thing to type, and the answer comes back grounded in your actual data.

What Plutus doesn’t do

Plutus has read-only access to your infrastructure, and that’s a design decision rather than a gap we’re working toward. We don’t buy commitments on your behalf, we don’t shut down idle resources, and we don’t hold write credentials into your cloud accounts. A tool that watches your spend shouldn’t also be able to change it. If automated commitment purchasing is what you need, that’s a different product and you should buy one built for it.

Our pricing works the same way: a flat monthly number that doesn’t move when your bill does. We never take a percentage of the spend we’re supposed to be helping you reduce.
