Polar — A billing platform for the intelligence era

Introducing the Polar Startup Program

The finance layer for intelligent software

A financial substrate for modern software, from first inference call to net revenue.

Usage Billing

Meter tokens, API calls, compute, storage. Bill with precision down to the event.

Subscriptions

Recurring plans with trials, upgrades, proration, and dunning built in.

Seats

Pricing that scales with your customer's teams. Add, remove, prorate automatically.

Powerful usage billing for modern software

Meter anything your product does. Compose it with subscriptions, seats, credits, and trials into whatever shape your pricing takes.

Measure the usage

Every call, token, and second your users consume, recorded the moment it happens.

Calculate the charge

Raw events roll into priced units. Per seat, per token, tiered or hybrid. However you wish to price.

Merchant of Record

We take on all the liability. Sales tax, VAT & chargebacks land on our name, not yours.

Know your unit economics

Revenue, costs & margins in one overview. The unit economics every AI startup needs to scale with confidence.

Your power users cost you money

Polar breaks down spend customer by customer, so you catch the ones bleeding your margins before they bleed your runway.

Turn any AI workload into revenue

From token-metered APIs to autonomous agents and GPU workloads. Polar fits how modern AI products actually charge.

AI completions

Wrap any model from the Vercel AI SDK with the Polar LLMStrategy. Token usage is metered and billed automatically on every call.

import { Ingestion } from '@polar-sh/ingestion'
import { LLMStrategy } from '@polar-sh/ingestion/strategies/LLM'
import { generateText } from 'ai'
import { openai } from '@ai-sdk/openai'

const llm = Ingestion({ accessToken: process.env.POLAR_ACCESS_TOKEN })
  .strategy(new LLMStrategy(openai('gpt-4o')))
  .ingest('openai-usage')

const { text } = await generateText({
  model: llm.client({ customerId: user.id }),
  prompt,
})

Everything between usage & revenueRaw usage goes in. Revenue comes out. We handle everything in between.

Polar is the financial layer for a new generation of intelligent software.

What industry leaders think about Polar

From AI startups to infrastructure veterans, the teams building the future ship production billing on Polar in days, not weeks.

Polar's Python SDK and Webhook infrastructure made our billing integration straightforward.

It gave us production-ready billing in hours, not weeks.

It's rare to find a vendor that moves this fast.

Siavash GhorbaniStilla AI

The speed at which Polar is executing on the financial infrastructure primitives the new world needs is very impressive.

I've joined Polar as an advisor!

I think it benefits everyone for devs to have more options to get paid to work on their passions, to support upstreams, and for users to have more confidence/transparency in the software they're supporting/purchasing.

Mitchell HashimotoGhostty

Polar has been giving us the high attention support of a startup, with an enterprise-level product and service.

Sebastián RamírezFastAPI

We switched to @polar_sh because of their killer API, UX, and product. Also love that it's Open-Source. Their team cares A LOT as well. Worth the minor fee difference.
