Top 7 alternatives to Metronome for usage-based billing

Metronome built the metering engine behind some of the largest usage-based businesses in software. OpenAI, Anthropic, Databricks and Confluent run billing through it. If your problem is ingesting billions of events and rating them against complex contracts, Metronome does that well.

What changed in 2026: Metronome is now part of Stripe

In January 2026 Stripe announced it was acquiring Metronome for a reported $1 billion. The acquisition has completed and Metronome is now a Stripe company. Stripe's CEO framed usage-based pricing as "a defining feature of the next decade", and buying the best-known metering engine is how Stripe intends to own it.

For buyers that reshapes the evaluation. Metronome's roadmap will converge with Stripe Billing and Stripe Payments. That is a good outcome if you are all-in on Stripe. It is a harder fit if you process payments with another provider, run multi-entity billing across regions, or wanted a metering layer that stays neutral. And it does not change what Metronome never covered: quoting, contracts, revenue recognition, CRM workflows and finance-facing controls still live in other tools.

If you are weighing alternatives to Metronome in 2026, here are seven platforms worth evaluating, starting with the one that covers the full revenue process in a single system.

1. Hyperline

Hyperline is a unified revenue platform that consolidates quote-to-cash into a single system of record. Where Metronome starts and stops at metering and rating, Hyperline wraps native usage-based billing into quoting, contracts, billing, invoicing, payment collection, revenue recognition and reporting.

Three differences matter most. Scope: Hyperline covers the whole lifecycle, so finance does not stitch a CPQ, a tax engine and a reporting tool around the metering layer. Autonomy: finance and RevOps teams configure meters, prices and contracts without a sprint. Independence: Hyperline sits on top of Stripe, Adyen, GoCardless, Mollie and Airwallex, so you keep your processor and add the billing layer above it.

Key Features:

• Real-time usage ingestion via API or database connectors, with sub-second latency
• Native hybrid pricing: flat, tiered, volume, graduated, usage-based, prepaid credits and commits in one engine
• Integrated CPQ with HubSpot and Salesforce widgets, approvals and e-signature
• Built-in e-invoicing certified in 80+ territories, compliant invoicing in 100+ countries
• Revenue recognition, reconciliation and real-time revenue alerts
• 99.99% uptime, SOC2, ISO27001, GDPR certified
• Real-time expert support responding in under 10 minutes

Ideal For:

B2B SaaS and AI companies that need Metronome-grade usage billing plus the rest of the revenue stack, sell through a sales team, invoice internationally, or want to stay neutral on payment processing.

Pros:

• Full quote-to-cash in one system, no stitching together metering plus CPQ plus tax plus reporting
• Finance teams change pricing without engineering
• Processor-agnostic, including Stripe
• Eliminates up to 80% of manual finance work, 99.9% reconciliation accuracy
• 4.9/5 on G2, 500M+ invoices processed, customers include ScorePlay, Lemlist, Formance and Truvi

Cons:

• Broader scope than a team that only needs a metering API may want
• Newer brand than Stripe, though the track record across high-growth SaaS is strong

Pricing:

Custom pricing based on revenue volume and feature scope. Book a demo for a tailored quote.

2. Lago

Lago is the open-source usage-based billing platform for engineering teams that want full control. It is API-first, supports any pricing model you can express in code, and self-hosts for data residency requirements.

3. Orb

Orb is a pure-play usage-based billing engine for AI companies, API businesses and high-volume event-driven SaaS. Adyen announced its $335 million acquisition of Orb on 11 June 2026 and the deal closed on 1 July 2026, so Orb, like Metronome, now belongs to a payment processor.

Key Features: event ingestion at scale, real-time metering, complex pricing rules, revenue analytics.

Ideal For: AI and ML API businesses, developer platforms, high-volume metered SaaS, especially those processing with Adyen.

Pros: excellent metering engine, strong developer ergonomics, usage-based from day one.

4. M3ter

M3ter focuses on usage-based pricing for enterprise software companies. Built by former AWS metering leads, it handles commit-and-draw contracts, overages and pricing simulations at enterprise scale, and it has stayed independent.

Key Features: real-time metering, commit-based deal support, pricing simulation sandbox, SOC2 compliance.

Ideal For: enterprise software vendors with complex commit-and-draw or overage contracts.

Pros: purpose-built for enterprise usage-based pricing, strong pricing sandbox, solid API coverage, independent.

Cons: limited scope beyond metering, customers need a separate invoicing layer for multi-currency and localized tax.

Pricing: custom enterprise pricing.

5. Zenskar

Zenskar blends subscription and usage-based billing with a no-code configuration layer, aimed at finance teams that want flexibility without an engineering dependency.

Key Features: hybrid billing, no-code pricing editor, automated revenue recognition, customer portal.

Ideal For: finance-led mid-market SaaS moving from flat subscriptions to hybrid pricing.

Pros: no-code pricing setup, flexible contract models, faster iteration than engineering-led tools.

Cons: smaller partner ecosystem, shorter track record at very high event volumes.

Pricing: custom, based on billed volume and feature tier.

Ideal For: early to mid-stage SaaS iterating on pricing.

Pros: fast to deploy, flexible for experiments, clean UX.

Cons: young product, limited enterprise track record.

Pricing: custom, based on tier and volume.

Is Hyperline Right for You?

If Metronome gave you metering at scale but the Stripe acquisition, the missing CPQ or the engineering dependency now gives you pause, Hyperline is the most complete alternative on this list. It matches real-time usage billing and adds quoting, invoicing, revenue recognition and compliance in one platform, without deciding your payment processor for you.

Teams that choose Hyperline over Metronome usually share three traits: they sell usage and commits through a sales team, they invoice across several countries, and they want finance to own pricing changes.
