Feature-by-feature, with sources cited, gaps admitted.
Every below links to a live page you can hit right now. No "contact sales" walls.
Multi-step autonomous agents are the 2026 spend category nobody else measures.
| Feature | CARTIE | Vantage | Apptio | CloudHealth | CloudZero | Kubecost | Helicone |
|---|---|---|---|---|---|---|---|
Per-agent-run cost rollup Helicone has session view but no agent_run_id hierarchy with parent_step_index. | |||||||
Runaway hard-cap pre-check API Agent calls /check-budget BEFORE each step; we recommend kill if over hard_cap. | |||||||
Per-run ROI (outcome ↔ cost) Finish a run with outcome_value_usd → roi_multiplier verdict. | |||||||
Rolling-median runaway detection Flags runs with cost or depth ≥ 2× rolling-7d median for the same agent name. |
The things teams pay for and forget — zombie pods, cold embeddings, retried tokens, bloat prompts.
| Feature | CARTIE | Vantage | Apptio | CloudHealth | CloudZero | Kubecost | Helicone |
|---|---|---|---|---|---|---|---|
Orphaned Kubernetes services (zombie detector) Kubecost is full-feature parity; we layer an engineer-hour payback gate they lack. | |||||||
Unnecessary LLM retry cost audit Helicone surfaces retry logs but doesnt quantify $ wasted. | |||||||
Over-context prompt optimizer Compresses bloated system prompts 50-75% — input-token reduction every call. | |||||||
Embedding-store cold-namespace audit Pinecone/pgvector graveyard detection — nobody else even crawls this. | |||||||
Idle AI endpoint detector (cold budgets) Features with configured budgets but zero traffic in N days = forgotten deployments. | |||||||
Duplicated pipeline / SaaS overlap detection Apptio has SaaS module but doesnt join SaaS ↔ Cloud (Datadog vs CloudWatch). | |||||||
Okta SCIM SaaS auto-discovery Connect Okta once → CARTIE auto-imports every SaaS app + cross-references against existing subscriptions for overlap. | |||||||
Airflow / Dagster pipeline DAG dedup (Jaccard + lineage) WORLD-FIRST. Detects customer_etl_v1/v2/FINAL-style duplicate pipelines via task-shape AND data-lineage Jaccard. |
Per-customer · per-team · per-feature attribution in shared infrastructure.
| Feature | CARTIE | Vantage | Apptio | CloudHealth | CloudZero | Kubecost | Helicone |
|---|---|---|---|---|---|---|---|
Per-customer P&L (Stripe-revenue join) CloudZero ships Customer-Cost Intelligence — direct competitor here. | |||||||
Per-pod Shapley cost attribution (K8s) Kubecost uses proportional split; we use Castro-2009 Monte-Carlo Shapley — provably fair. | |||||||
Per-feature AI profitability (revenue ÷ cost) CloudZero/Helicone show feature cost — neither joins to revenue for ROI. | |||||||
Total Cost of Feature (TCF) 4-source join Cloud + LLM + SaaS + engineer-hours = total feature cost. WORLD-FIRST. |
Optimize for profit and conversion — not raw cost reduction.
| Feature | CARTIE | Vantage | Apptio | CloudHealth | CloudZero | Kubecost | Helicone |
|---|---|---|---|---|---|---|---|
Cost ↔ Conversion event join (ROI per feature) CloudZero shows cost-per-customer; we go further with feature-level event join. | |||||||
PostHog / Mixpanel webhook signature verification HMAC-SHA256 verification on every inbound webhook. Shipped Feb 18, 2026. | |||||||
Jira / Linear webhook adapter for roadmap auto-import Label-based extraction (launch + finops-delta:* / cartie-customers:*) + HMAC verify + idempotency. | |||||||
Engineer-hour payback filter (3× ROI gate) Refuses to recommend below 3× first-year ROI. No vendor refuses recommendations. | |||||||
Roadmap-aware Monte Carlo forecast Apptio has good forecasting; ours injects Jira/Linear launch events into fan chart. | |||||||
PR-time cost guardrail (engineer-hour math) WARN/BLOCK PRs on cost-to-value ratio. Infracost does $ deltas; we add value math. |
The "is this just marketing?" gap every FinOps tool struggles with.
| Feature | CARTIE | Vantage | Apptio | CloudHealth | CloudZero | Kubecost | Helicone |
|---|---|---|---|---|---|---|---|
3× ROI Pledge (binding refund contract) Versioned, machine-readable, curl-able. No FinOps vendor has this. | |||||||
Public algorithm correctness manifest Live endpoint returns test count + axiom list. Any HN commenter can verify. | |||||||
Continuous commitment rebalancer (ledger) Vantage/Apptio recommend once; we watch 30/60/90d windows + ledger every rebalance. |
Where we admit the gap — and tell you when it ships.
| Feature | CARTIE | Vantage | Apptio | CloudHealth | CloudZero | Kubecost | Helicone |
|---|---|---|---|---|---|---|---|
SOC 2 Type II certification (A-LIGN audit, public readiness matrix live) Type I controls in place, Type II audit targeted June 15, 2026. Live readiness matrix (83% complete) at /soc2-readiness — we publish what we have and what is pending. |
Every other FinOps comparison page is written by sales. They pick the rows they win, hide the rows they lose, and pad with "Generally Available" claims that don't survive a curl.
We listed 4 rows we don't have yet ("Honestly: What We Don't Have Yet" category) and put an ETA next to each. We don't believe in contact sales. We don't believe in stripping competitor advantages off the matrix.
Click any in the matrix. If the live page doesn't load, the row gets demoted. That's our integrity contract.
