Metronome is enterprise usage-based billing with SQL-defined metering, invoicing at cycle end (acquired by Stripe in January 2026). Credyt is real-time billing infrastructure with per-usage authorization against the customer's balance. This article compares their architectures, features, pricing, and use cases, with a focus on non-enterprise AI companies.
At a glance
Metronome: A usage-based billing platform for software and AI companies with high event volumes and complex enterprise contracts. Metronome was acquired by Stripe in January 2026 (definitive agreement December 2, 2025; close January 14, 2026) and is positioned as Stripe's enterprise usage billing engine. Pricing requires a sales conversation. Cloud only, proprietary.
Credyt: Real-time billing infrastructure for AI products. The platform authorizes each request against the customer's balance before the work runs; usage is debited from the wallet atomically as the event arrives. Public flat pricing: $1 per Monthly Active Wallet, first 10 wallets free.
Drop-in branded billing portal customers self-serve from. Cloud only, proprietary.
What does Metronome do?
Metronome captures high volumes of usage events through a streaming aggregation architecture and bills them on a configurable invoice cycle. Customers define billable metrics in SQL, which lets billing engineers express complex aggregation logic without bespoke pipelines. Enterprise contract management is first-class: multi-year contracts, commitments, amendments, true-ups, and a 34-day backdating window for retroactive corrections.
The platform supports multi-motion go-to-market on a single billing surface. Anyscale, for example, runs unified self-serve, sales-led enterprise, and cloud marketplace billing (AWS, Azure, GCP) through Metronome (Metronome customer story). Cribl reported saving 1,000+ hours and 3+ headcount on its Cribl.Cloud consumption billing implementation (Metronome customer story).
Named customers include OpenAI, Anthropic, Databricks, NVIDIA, Anyscale, Confluent, Intercom, and Lovable for credit burndown (Stripe blog: Metronome + Stripe, January 23, 2026). The November 2025 AI Launch Week positioned the platform as monetization infrastructure for the AI economy and claimed billions of usage events processed monthly (Business Wire, November 12, 2025).
Where Credyt differs
Credyt is real-time billing, not invoice-based usage-based billing. The architectural difference shows up in three places that matter for AI products.
Authorization happens before the action. The platform calls Credyt's Wallet APIs before executing usage; if the customer's balance is insufficient, the platform blocks the request. Once approved, the usage event is submitted and Credyt prices it, generates the fee, and debits the wallet in a single atomic operation. Metronome records usage in real time and offers a cost preview API, but usage is billed at cycle end, not at the moment of consumption. For products where per-inference cost is real, that timing gap is the difference between bounded and unbounded margin exposure.
Pricing is public and flat. Credyt publishes $1 per Monthly Active Wallet with the first 10 wallets free, no platform fee, no seat fees, no revenue percentage, and 1M events per month included. Metronome does not publish pricing; enterprise contracts are quoted after a sales conversation. The opacity is a deliberate go-to-market signal. Metronome is sized for buyers who run procurement, not for builders who evaluate on the docs site.
The customer portal is hosted, not embedded. Credyt ships a branded billing portal the platform links to from its app. Customers see their balance, usage history, top-up options, and customer-controlled auto top-up settings without the platform writing frontend code. Metronome ships signed-URL embeddable dashboards that the platform integrates into its own product UI, and auto top-up is configured by the merchant on the customer's behalf rather than self-serve from the customer side.
How do Credyt and Metronome compare on features?
Credyt and Metronome diverge on three dimensions that matter most for AI billing: when usage is billed (before the action vs at cycle end), what the customer's primary entity is (wallet vs invoice), and how pricing is discovered (publicly vs through sales).
| Dimension | Credyt | Metronome |
|---|---|---|
| Billing model | Hybrid (real-time wallet debit + subscriptions) | Invoice-based |
| Usage authorization | Per-usage (before the action) | Post-usage |
| Usage tracking | Real-time usage billing (recorded and debited atomically) | Real-time metering + periodic invoice |
| Wallet architecture | First-class primitive | Add-on (prepaid credits and credit burndown) |
| Multi-asset support | Native (USD, tokens, credits, GPU hours, custom units) | USD with labeled credit units |
| Customer portal | Drop-in branded portal (Credyt-hosted; link from app) | Build-your-own (signed-URL embeddable dashboards) |
| Auto top-up | Customer-controlled | Platform-configured |
| Enterprise contracts | Not supported | First-class (multi-year, commits, true-ups, 34-day backdating) |
| Profitability analytics | Event-level (per-customer, per-feature, per-workload) | Aggregate (revenue analytics, margin analysis) |
| Public pricing | Yes ($1/MAW, first 10 free) | No (sales required) |
| Deployment | Cloud only | Cloud only |

How do Credyt and Metronome compare on pricing?
At 100 customers, Credyt costs $90 per month plus pass-through PSP fees. Metronome's pricing is not publicly available and requires a sales conversation. The estimate uses the canonical scenario: $20 average revenue per customer per month, 1,000 events per customer per month, 5 platform seats, $2,000 in monthly revenue, and 100,000 usage events.
| Component | Credyt | Metronome |
|---|---|---|
| Platform / base fee | $0 | Not publicly available |
| Per-customer fees | $90 ($1/MAW × 90 paid wallets; first 10 free) | Not publicly available |
| Seat fees | $0 | Not publicly available |
| Event ingestion fees | $0 (within 1M/month free allowance) | Not publicly available |
| Revenue % overage | $0 | Not publicly available |
| Payment processing | Pass-through (PSP rate) | Pass-through (PSP rate) |
| Total monthly | $90 + PSP fees | Not publicly available (sales required) |
Metronome does not publish pricing, so this scenario cannot be computed from public information. Metronome does not process payments directly; payment collection runs through the customer's PSP (typically Stripe) at the PSP's published rates (Metronome website, accessed April 2026).
When does Metronome fit?
Metronome is the right call when:
- The team has multi-year enterprise contracts with commitments, amendments, and true-ups
- Usage volumes hit billions of events per month with sustained throughput requirements
- Pricing is multi-dimensional enough to benefit from SQL-defined billable metrics authored by billing engineers
- The go-to-market combines self-serve, sales-led enterprise, and cloud marketplace billing (AWS, Azure, GCP) on a single platform
- Deep Stripe ecosystem integration is part of the long-term plan: global payments, tax, ASC 606 revenue recognition
- Billing engineering and finance teams are staffed to own a sophisticated invoice-based system
When does Credyt fit?
Credyt is the right call when:
- The product has per-request inference cost that needs to be bounded at authorization time, not discovered at invoice time
- The billing model is pre-funded credits or hybrid (subscription plus usage-based overage) where the customer's balance is the source of truth
- Public, predictable pricing is a hard requirement; non-enterprise teams need to evaluate without a sales call
- The team needs to ship billing without frontend engineering bandwidth (drop-in branded portal vs build-your-own embedded components)
- The product is being built inside an AI coding tool that supports MCP (Cursor, Claude Code, Lovable, Bolt, Replit, V0, Windsurf, Codex), where billing is configured by prompt rather than backend code
Teams looking for alternatives to Metronome that ship public pricing and a drop-in portal usually start here, because the architectural fit matches a different reader than the one Metronome targets.
How do the architectures differ?
Credyt and Metronome diverge on two dimensions: when usage is billed (cycle end vs the moment of consumption) and whether the invoice or the wallet is the primary entity. The subsections below cover each axis.
Real-time per-usage authorization vs post-usage invoicing
Metronome records usage in real time through streaming aggregation, rates events at cycle end, and produces an invoice. A cost preview API and pending-invoice visibility surface accumulated charges in flight, but the invoice is generated when the cycle closes, not at the moment of consumption. If a customer exhausts a budget mid-cycle, the platform discovers it at invoice generation, not at the moment of usage.
Credyt inverts the timing. The platform queries the Wallet API before the action. If the balance is sufficient, the action proceeds and the wallet is debited atomically as the usage event is submitted. If not, the platform blocks. The decision to allow or block is the platform's; Credyt provides the real-time balance state and the atomic debit that make the decision possible. For products with measurable per-request COGS, that timing distinction is the difference between protecting margins and watching them compound away.
First-class wallet primitive vs invoice-based add-on
Metronome's primary entity is the invoice. Prepaid credits and credit burndown are available as features layered on top of the rating engine; the invoice is the source of truth for what the customer owes, and balances are computed from meter totals at billing time.
In Credyt, the wallet is the primary entity. The customer's balance updates on every event in real time. There is no metering-then-reconciliation handoff because there is no separate metering stage to hand off from.
If the product needs the customer's balance to be the source of truth (prepaid AI credits, top-up flows, balance-threshold webhooks), the wallet has to be a first-class primitive. If the invoice is the source of truth (enterprise SaaS with quarterly contracts), the wallet can be an add-on. We built Credyt this way because AI products do not get to wait until cycle end to learn what a customer cost; the wallet has to know now or the margin is already gone.
Bottom line
Metronome and Credyt solve different versions of the usage-based billing problem. Metronome is enterprise invoice-based billing with SQL-defined metering, sales-led pricing, and embeddable portal components, now part of Stripe's enterprise stack. Credyt is real-time billing with per-usage authorization, public flat pricing, and a drop-in branded portal, sized for non-enterprise AI companies where inference cost hits before the invoice closes.
Frequently asked questions
Can Metronome block usage before a customer's balance runs out?
No. Metronome's invoice-based model records usage and rates it at cycle end. Spend alerts and a cost preview API surface accumulated charges in flight, but there is no real-time wallet debit that reserves funds before consumption (Metronome documentation, accessed April 2026). Credyt's per-usage authorization model is built around that block: the platform queries the customer's balance before each action and rejects the request if balance is insufficient.
Does Metronome publish pricing?
No. Metronome's pricing is quoted after a sales conversation; no public tiers, base fees, per-event rates, or seat fees are documented on the Metronome website (Metronome website, accessed April 2026). Credyt publishes a single rate: $1 per Monthly Active Wallet, first 10 free, no revenue percentage, no markup on PSP fees.
Does Metronome ship a drop-in customer portal?
Not in the sense of a hosted portal the platform links to. Metronome provides embeddable dashboards through signed URLs that the platform integrates into its own product interface (Metronome documentation, accessed April 2026). Credyt ships a hosted branded billing portal; the platform adds a "Manage billing" link from its app and customers see balance, usage history, top-ups, and auto top-up controls without frontend engineering work.
Is Metronome a good fit for small companies?
Metronome is documented as mid-market to large enterprise. The platform is designed for high-volume infrastructure companies with dedicated billing engineering and finance teams (Business Wire, November 12, 2025). Small companies and non-enterprise AI teams typically look at alternatives: Credyt for the real-time wallet model, Orb for another invoice-based usage-based billing platform, or Lago for an open-source self-hosted option.
Now that Stripe has acquired Metronome, should I just use Stripe Billing?
Stripe positioned Metronome as the enterprise usage billing engine of the combined offering, not as a replacement for Stripe Billing (Stripe blog: Metronome + Stripe, January 23, 2026). Stripe Billing remains subscription-first with metered add-ons; Metronome is invoice-based usage-based billing at enterprise scale. The two products serve different shapes of buyer, and the post-acquisition story is integration, not consolidation. See Credyt vs Stripe Billing for the Stripe-side comparison.
Can my customers control their own auto top-up in Metronome?
No. Auto top-up in Metronome is platform-configured: the merchant sets thresholds and refill amounts on behalf of customers (Metronome documentation, accessed April 2026). In Credyt, customers configure their own threshold and refill amount directly in the billing portal. Both models serve valid use cases; the difference matters for products where customer self-service is a feature rather than a risk.
What alternatives to Metronome should I consider for AI billing?
Four directions worth a look:
- Credyt, for real-time per-usage authorization, public pricing, and a drop-in portal sized for non-enterprise AI companies.
- Orb, for another invoice-based usage-based billing platform with strong support for rapid pricing iteration.
- Lago, for an open-source self-hosted option where the team wants full code control and is willing to operate the infrastructure.
- Stigg, for real-time entitlement orchestration layered over an existing billing engine like Stripe or Zuora.
