The FinOps Directory

The independent FinOps directory

The CFO's toolkit for AI & cloud spend.

You can't cut what you can't see. This is the working list of tools a finance leader uses to put AI, cloud, Kubernetes, and SaaS spend back under control — categorized, with what each one is actually for.

Curated for finance & FinOps leaders Updated 2026 6 categories · 20+ tools

AI & LLM spend control

The newest and fastest-growing line on the bill. These tools attribute model and agent spend to the user, app, or task that caused it — so the AI invoice stops being a number nobody can decompose.

Helicone

Open source

Drop-in LLM observability. Logs every prompt and response with token cost, latency, and per-user / per-key spend — a one-line proxy change to start seeing where the tokens go.

Best for: engineering teams that want LLM cost logging without a rollout.
helicone.ai →

Langfuse

Open source

LLM engineering platform with cost and usage tracing across chains and multi-step agents — so spend is attributed to a whole agent run, not just a single call.

Best for: tracing the true cost of agentic, multi-step workflows.
langfuse.com →

AI gateway that puts budgets, rate limits, and per-virtual-key cost controls in front of every provider — enforce a spend ceiling instead of discovering it at month-end.

Best for: enforcing hard AI budgets at the gateway.
portkey.ai →

LiteLLM

Open source

Proxy that normalizes 100+ model providers behind one API, with per-key budgets and spend tracking — one place to cap and report on a sprawling model mix.

Best for: teams routing many models behind a single budget.
litellm.ai →

Cloud cost management & FinOps platforms

The core of the discipline: allocate multi-cloud spend to teams and products, forecast it, and surface the rightsizing and commitment opportunities.

Cost reporting and optimization across AWS, GCP, Azure, Datadog, Snowflake and more, with per-team allocation and savings recommendations — fast to stand up.

Best for: multi-cloud visibility without a heavy enterprise rollout.
vantage.sh →

Cost intelligence that maps cloud spend to unit economics — cost per customer, feature, or product — so finance can connect the cloud bill to the P&L and gross margin.

Best for: tying cloud cost to unit economics and margin.
cloudzero.com →

Enterprise FinOps platform (IBM) for cost allocation, forecasting, chargeback/showback, and rightsizing across clouds — built for scale and governance.

Best for: large enterprises with chargeback and audit needs.
apptio.com →

Unifies cloud, Kubernetes, and SaaS spend with virtual tagging ("MegaBill") — so shared and untagged cost finally gets allocated to an owner.

Best for: allocating shared and untagged spend.
finout.io →

FinOps platform purpose-built for finance + engineering collaboration across cloud and Kubernetes, with budgets, anomalies, and accountability workflows.

Best for: shared finance–engineering FinOps workflows.
ternary.app →

AWS cost optimization with automated rightsizing and commitment management — points the savings engine directly at an AWS-heavy footprint.

Best for: AWS-centric shops wanting automated optimization.
nops.io →

Kubernetes cost

Containers hide cost behind shared nodes. These attribute spend down to the namespace, deployment, and team.

Real-time Kubernetes cost monitoring and allocation by namespace, deployment, label, and team, with rightsizing recommendations for requests and limits.

Best for: attributing and trimming k8s spend.
kubecost.com →

OpenCost

Open source

The CNCF open standard for Kubernetes cost monitoring — vendor-neutral allocation you can run yourself and build on.

Best for: vendor-neutral, self-hosted k8s cost.
opencost.io →

Automated savings & commitments

Hands-off optimization: let software manage reservations, savings plans, and spot capacity so you're not leaving discounts on the table.

Autonomously manages AWS and GCP commitments (Reserved Instances, Savings Plans) to maximize the effective savings rate — with no long lock-in of your own.

Best for: hands-off commitment optimization.
prosperops.com →

Automates spot-instance and commitment usage to cut compute cost while protecting availability — squeezes the cheapest capacity out of interruptible workloads.

Best for: spot-eligible, fault-tolerant compute.
spot.io →

SaaS spend management

Software is the other runaway line. These find every app, license, and renewal — and help negotiate them down.

SaaS buying and procurement platform that benchmarks real pricing and helps negotiate renewals — turns "is this quote fair?" into a data answer.

Best for: cutting software contract and renewal spend.
vendr.com →

SaaS management for full visibility into every application, license, and renewal date — so you can rationalize licenses and kill shelfware.

Best for: license rationalization at scale.
zylo.com →

Spend management and procurement for SaaS and beyond, pairing workflow with pricing intelligence to drive savings on what you buy.

Best for: procurement workflow plus negotiated savings.
tropicapp.io →

SaaS management and subscription control with virtual cards — every subscription on its own card, visible and cancelable in one place.

Best for: SMBs getting subscription sprawl under control.
cledara.com →

Native cloud cost tools

Already in your bill, zero added spend. The right starting point before you buy a platform.

Cost Explorer, Budgets, and ML-based Cost Anomaly Detection — native visualization, forecasting, and alerting for AWS, free to use.

Best for: AWS-only teams starting with no extra spend.
aws.amazon.com →

Billing reports, budgets, and recommendations across GCP, with BigQuery billing export for custom analysis.

Best for: GCP-native cost reporting and analysis.
cloud.google.com →

Cost analysis, budgets, and recommendations for Azure (and connected AWS), built into the portal.

Best for: Azure-native cost control.
azure.microsoft.com →
