Multi-step autonomous agents are the 2026 spend category nobody else measures.
| Feature | CARTIE | Vantage | Apptio | CloudHealth | CloudZero | Kubecost | Helicone | Datadog | Spot.io | Turbonomic | CAST AI | TrueFoundry | Amnic | Mavvrik |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
Per-agent-run cost rollup Helicone has session view but no agent_run_id hierarchy with parent_step_index. TrueFoundry traces agents at the gateway; Mavvrik ships an OTel agent SDK — neither rolls up per-run cost hierarchies. | ||||||||||||||
Runaway hard-cap pre-check API Agent calls /check-budget BEFORE each step; we recommend kill if over hard_cap. TrueFoundry enforces gateway budgets/rate limits; Mavvrik ships budget guardrails — neither does per-step pre-check. | ||||||||||||||
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 | Datadog | Spot.io | Turbonomic | CAST AI | TrueFoundry | Amnic | Mavvrik |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
Orphaned Kubernetes services (zombie detector) Kubecost is full-feature parity; we layer an engineer-hour payback gate they lack. CAST AI removes empty nodes (infra-level); Amnic surfaces K8s idle via rightsizing recs. | ||||||||||||||
Unnecessary LLM retry cost audit Helicone/TrueFoundry surface retry logs but dont 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). Amnic/Mavvrik track SaaS spend alongside cloud — no overlap detection. | ||||||||||||||
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. | ||||||||||||||
Real-time LLM token arbitrage routing (Auto-Compiler Proxy) Live pricing index across 12 LLM providers + cheapest-quality-adjusted routing per task class. Helicone/TrueFoundry route by cost or latency; CAST AI's AI Enabler routes to cheap instances — none do live spot-burst detection or quality-floor scoring. | ||||||||||||||
Output-side verbosity waste audit (response diet) WORLD-FIRST. Output tokens cost 3-5× input — every other tool optimizes prompts only. We audit and shrink the response side: boilerplate tax, long-tail verbosity, prose-wrapped JSON. | ||||||||||||||
Multi-turn history resend tax analysis (memory compaction) WORLD-FIRST. Chat-history resend grows O(N²) per conversation. We quantify the tax from real proxy logs and prescribe the keep-last-N + rolling-summary policy that kills 40-70% of it. | ||||||||||||||
Cost SLOs with burn-rate math + projected exhaustion date WORLD-FIRST framing. Datadog/CloudZero/Amnic/Mavvrik ship threshold budget alerts (fire after the money is gone). We ship SRE error-budget burn rates: 1.5× burn flags weeks before breach, with the projected exhaustion day. | ||||||||||||||
AI capacity commitment math (PTU / provisioned-throughput ROI) WORLD-FIRST. The RI-optimizer play for AI: should you buy Azure OpenAI PTUs / Bedrock provisioned throughput or stay PAYG? Deterministic verdict with every price assumption disclosed and overridable. |
Per-customer · per-team · per-feature attribution in shared infrastructure.
| Feature | CARTIE | Vantage | Apptio | CloudHealth | CloudZero | Kubecost | Helicone | Datadog | Spot.io | Turbonomic | CAST AI | TrueFoundry | Amnic | Mavvrik |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
Per-customer P&L (Stripe-revenue join) CloudZero ships Customer-Cost Intelligence — direct competitor here. Amnic (unit economics) and Mavvrik (cost-to-serve) attribute cost per customer but dont join Stripe revenue. | ||||||||||||||
Per-pod Shapley cost attribution (K8s) Kubecost/CAST AI/Amnic use proportional or utilization splits; we use Castro-2009 Monte-Carlo Shapley — provably fair. | ||||||||||||||
Per-feature AI profitability (revenue ÷ cost) CloudZero/Helicone/Mavvrik show feature cost — none join 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 | Datadog | Spot.io | Turbonomic | CAST AI | TrueFoundry | Amnic | Mavvrik |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
Cost ↔ Conversion event join (ROI per feature) CloudZero shows cost-per-customer; Mavvrik markets cost-to-outcomes; 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; Amnic forecasts spend trends; 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 | Datadog | Spot.io | Turbonomic | CAST AI | TrueFoundry | Amnic | Mavvrik |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
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. | ||||||||||||||
Decision Ledger — two futures per decision, human-in-loop, graded forecasts WORLD-FIRST. Every money decision = Choice A vs Choice B with projected P&L, human approval trail, and predicted-vs-actual accuracy grading. No tool on earth grades its own forecasts. |
Where we admit the gap — and tell you when it ships.

SOC 2 Type II certification (A-LIGN audit, public readiness matrix live) Type I controls 100% implemented (21/21), Type II audit targeted September 30, 2026. Live readiness matrix at /soc2-readiness — we publish what we have and what is pending. CAST AI and TrueFoundry are certified; Amnic/Mavvrik do not publish audit status. |
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.
