5 Best Orb Alternatives in 2026
The best Orb alternatives for usage-based billing are Kribana, Metronome, Lago, Chargebee and Stripe Billing — teams switch when they need a native credit wallet, a dashboard instead of an engineering ticket for every price change, or automated payment recovery Orb doesn't provide out of the box. This guide compares real pricing models, genuine pros and cons, and — the part most guides skip — how much migration effort each switch actually takes.
- A genuinely strong metering and rating engine — built by engineers, for engineers, and it holds up at high event volume.
- A clean, well-documented event ingestion API that developers like working with.
- Flexible, programmatic pricing logic for teams who want full control expressed in code.
- A solid fit for infrastructure and API-first companies whose pricing is usage-only and whose engineering team owns billing end to end.
- Every price or plan change is a code change — it goes through an engineering PR and a deploy, not a dashboard edit.
- No customer portal, invoicing UI or dunning system ships with it — you build and maintain those yourself.
- No credit or prepaid wallet as a first-class primitive, so token- and credit-based pricing (increasingly the default for AI products) has to be hand-rolled on top of the metering layer.
- No automated payment recovery — failed charges route to whatever retry logic you build, not a system that reads the decline reason.
- ✓You're routing every plan or price change through an engineering sprint instead of a dashboard edit.
- ✓You're hand-building a credit ledger and top-up flow on top of Orb's metering primitives because your product runs on tokens or credits, not raw usage.
- ✓Failed payments pile up in a queue nobody owns, because there's no recovery automation reading the decline reason.
- ✓Finance or RevOps is asking for a customer portal and invoicing UI that simply doesn't exist yet.
- ✓You're billing AI agents or token-based usage and need a balance check before a request runs, not a reconciliation after the fact.
How we evaluated: pricing-model flexibility, native credit/prepaid support, migration effort, and what (if anything) automates after the invoice is issued.
Kribana
Best for: AI and SaaS companies billing on usage, credits, or a hybrid of both
- Real-time, idempotent usage-event ledger with metering, pricing and invoicing finished out of the box
- Native credit wallets — top-ups, low-balance alerts and burn-down tracking as first-class objects, not a workaround
- An agent that watches every account and runs top-up, recovery and expansion playbooks automatically, in autopilot, approve-first, or alert-only mode
- Pricing configured in a dashboard — Finance or RevOps can reprice without an engineering ticket
- Processor-neutral: Stripe, Razorpay, Adyen or Braintree, with a hosted or embedded customer portal
Free until billed revenue exceeds $25,000/month, then 0.6% of billed revenue above that threshold.
- ✓The only tool on this list with a native credit wallet and post-invoice automation in one platform
- ✓No build project — connect one event stream and pricing is live the same week
- ✓Native importers exist for teams migrating off Orb, Chargebee, Lago or Stripe
- ✕Younger platform than incumbents like Chargebee or Stripe Billing, with a shorter production track record
- ✕Fewer legacy ERP integrations today than enterprise-focused platforms like Zuora
Metronome
Best for: High-scale infrastructure, database and AI platform companies
- High-throughput metering and rating engine built for very large event volumes
- Flexible pricing-as-code model for engineering-owned billing
- Enterprise-paced support built for platform teams already operating at scale
Custom, usage-based pricing — not published.
- ✓Metering rigor that holds up at genuinely high scale
- ✓Strong fit if your team already thinks about pricing in code
- ✕No native payment recovery — declines route to your own tooling
- ✕No credit or prepaid wallet primitive, and no customer portal or invoicing UI shipped
- ✕Acquired by Stripe in January 2026 — worth watching for roadmap and pricing changes as the integration settles
Lago
Best for: Engineering-led teams that want an open-source metering core they control
- Open-source metering and billing API — self-host it or run it on Lago Cloud
- Credit and prepaid balance primitives available through the API
- Full control over deployment, data residency and infrastructure choices
Free and open-source if self-hosted; usage-based pricing on Lago Cloud.
- ✓No vendor lock-in — the code is yours to run, fork or extend
- ✓Real credit-balance primitives, unlike Orb or Metronome
- ✕Self-hosting means you own uptime, upgrades and infrastructure for the one system that can't go down
- ✕Portal, invoicing UI and dunning logic are yours to design and build on top of the API
- ✕No autonomous recovery or expansion layer — automation is something you build around the ledger
Chargebee
Best for: Subscription-first B2B SaaS adding usage-based components
- Mature subscription management, proration and dunning workflows
- Usage-based billing supported as an add-on to subscription plans
- Large, established customer base and integration ecosystem
Tiered subscription pricing plans, plus usage-based overage charges.
- ✓Deep subscription tooling if recurring plans are still your primary pricing model
- ✓Long production track record and broad third-party integrations
- ✕Usage pricing feels bolted onto a subscription core rather than built from it — proration rules pile up as usage grows
- ✕Dunning is scheduled retries, not decline-reason-aware recovery
- ✕Metered add-ons track simple counters, not the high-cardinality event ledgers AI and infrastructure pricing need
Stripe Billing
Best for: Teams already fully committed to Stripe as their only payment processor
- Billing built directly into the Stripe payments platform
- Metered billing for straightforward per-unit usage
- Standard dunning and retry rules on failed charges
A percentage of billed volume processed through Stripe.
- ✓The simplest option if Stripe is already your processor and pricing is simple metered usage
- ✓One vendor for payments and billing means one integration to maintain
- ✕Requires Stripe as your processor — switching or adding a second processor later means re-platforming billing too
- ✕Usage pricing beyond simple metered tiers (tiered, graduated, hybrid, credit-based) gets harder to express
- ✕Recovery follows Stripe's default retry schedule, not a decline-reason diagnosis
The part most alternatives guides skip: what actually happens when you switch. Every migration below runs the same way regardless of destination — stream events to both systems, mirror your current plans, validate one full billing cycle side-by-side, then cut over at the start of the next cycle.
How complex is your pricing model?
Simple, single-metric usage fits almost anything here. Tiered, graduated or hybrid usage-plus-subscription pricing narrows it to Kribana, Metronome or Lago — Chargebee and Stripe Billing get harder to configure once pricing goes beyond straightforward metered tiers.
Do you need prepaid credits or wallets?
If your product runs on tokens, credits or any prepaid balance — increasingly the default for AI products — Kribana and Lago have real credit primitives. Metronome, Chargebee and Stripe Billing all require you to build that layer yourself.
How much engineering bandwidth do you have to dedicate to billing?
Low bandwidth points to Kribana or Chargebee, where pricing is dashboard-configured. High bandwidth and a preference for full programmatic control points to Metronome or self-hosted Lago, where more of the system is yours to build.
Do you want billing tied to a single payment processor?
Stripe Billing only works if Stripe is your processor, permanently. Kribana is processor-neutral by design, so you can run or switch processors without a second billing migration later.
What should happen after the invoice — automated recovery, or is reporting enough?
If you want failed payments retried by decline reason, low balances topped up automatically and expansion signals flagged without a human watching a dashboard, Kribana's agent is the only option here built for that. Everyone else stops at the invoice.
What is the best Orb alternative for AI companies?
Kribana is the strongest fit for AI companies specifically, because it pairs Orb-level usage metering with native credit wallets — the pricing primitive most AI products actually run on — plus an agent that handles low-balance alerts and top-ups automatically. Metronome and Lago are reasonable alternatives if your team wants to build the credit and automation layer itself; Chargebee and Stripe Billing are better suited to subscription-first products with lighter usage components.
Which billing platforms support credit-based and prepaid pricing?
Kribana and Lago both treat credits as a first-class object rather than a workaround. Kribana ships native wallets with top-ups and low-balance alerts built in; Lago exposes credit primitives through its API that you assemble yourself. Metronome, Chargebee and Stripe Billing don't have a dedicated credit-wallet object — teams on those platforms typically simulate prepaid balances with custom logic on top of the core ledger.
How hard is it to migrate off Orb?
It depends on the destination, not just the source. Kribana ships a native importer for Orb's usage events and invoice history, so most teams go live in one to two weeks running in parallel before cutover. Moving to Metronome or Lago involves an API export and manual re-mapping since there's no vendor-provided switch path from Orb, which typically takes longer and carries more integration risk.
Can I combine subscriptions with usage-based billing?
Yes, and most growing companies eventually do — a base subscription plus metered overage, or a subscription that includes a bundle of credits. Kribana and Chargebee both support this natively; Chargebee approaches it from the subscription side with usage as an add-on, while Kribana treats usage as the foundation with subscriptions as one configuration on top. Orb and Metronome can express hybrid pricing too, but it's built in code rather than configured in a dashboard.
Does Stripe's acquisition of Metronome change which tool I should pick?
It's a reasonable factor to weigh, not a reason to rule Metronome out on its own. Stripe acquired Metronome in January 2026, and how that changes Metronome's roadmap, pricing and independence from the rest of the Stripe ecosystem is still playing out. If staying processor-independent matters to you, that consolidation is worth factoring into the decision alongside the product gaps above, not treating as the deciding factor by itself.
If you're self-serve and product-led with simple usage pricing, Stripe Billing is the path of least resistance as long as you're never switching processors. If you're sales-led B2B with subscriptions as the core, Chargebee's dunning and proration tooling still leads. If you want to stay fully in control of your infrastructure and don't mind building the rest of billing yourself, Lago's open-source core or Metronome's rating engine both hold up at scale. If you're AI-native, billing on tokens or credits, and want the balance checks, recovery and expansion automation handled for you instead of built from scratch, that's exactly what Kribana is built for.
