Short answer: For MRR you can trust, with seats counted and usage kept out, plus revenue by marketing channel, Chartsy. For headline numbers from a single Polar organization with no setup, Polar's built-in analytics. If you already use ChartMogul for other billing systems and have engineering time, an import into ChartMogul. If you have a data engineer and unusual reporting needs, the Polar API plus a spreadsheet or BI tool.

Polar.sh has become a popular merchant of record for developers and indie SaaS founders: it handles checkout, subscriptions, seats, usage billing and global tax, and it ships its own analytics dashboard. For a first product, that dashboard is often enough. Once you have real MRR, though, the questions change - what moved MRR this month, which plans are expanding, and which marketing channels actually bring paying customers - and that is where you need a dedicated Polar analytics tool.
This guide compares the best Polar.sh analytics tools in 2026: what each covers, where it stops, and which kind of Polar-billed business it fits.
What a Good Polar Analytics Tool Should Do
Polar's billing model has a few features that generic analytics tools handle badly. Before comparing options, check that a tool can:
- Separate recurring revenue from everything else. Polar sells subscriptions, usage-based billing and one-time products from the same account. Usage charges, prorations and one-time purchases are revenue, but they are not MRR. Mixing them in makes MRR jump around for reasons that have nothing to do with subscriptions.
- Count seats correctly. A per-seat plan with 12 seats is 12 seats' worth of MRR, not one subscription at the base price.
- Report net revenue, not just gross. As a merchant of record, Polar collects tax and takes its fee before you are paid. You want to see revenue after tax and Polar's fee, so the number matches what lands in your payouts.
- Handle cancellations the way access works. A subscription cancelled at period end is still a paying customer until that period runs out. Churn should land on that date, not the day someone clicked cancel.
- Show where customers came from. Polar knows who paid, not which blog post, launch or ad brought them. Attribution needs your website traffic and your Polar orders in the same place.
- Combine accounts. Many founders run more than one Polar organization, or Polar next to Stripe, Paddle or Lemon Squeezy. A useful tool adds them up into one MRR number.
How we evaluated these tools
We compared each option on the same points:
- Price at an indie founder's stage, and what it's priced on.
- Polar connection. Native connector, API import, or something you build.
- Metric accuracy. Seats counted, usage and one-time revenue kept out of MRR, and cancellations churned when paid access ends.
- Net revenue. Whether tax and Polar's fee come out of the number.
- Attribution. Whether you can see which marketing channels brought paying customers.
- AI and MCP. Whether you can ask Claude, ChatGPT or Cursor about your revenue.
The Best Polar.sh Analytics Tools
1. Chartsy - Best for Clear MRR and Revenue Attribution on Polar
Chartsy is the revenue and growth dashboard built for SaaS founders. You connect Polar with an Organization Access Token, Chartsy adds a webhook for you, and your last 24 months of history sync automatically. New orders, refunds and subscription changes show up within a minute.
Chartsy reads Polar the way a founder would want it read:
- MRR comes from paid subscription orders, normalized to a month, with every seat counted on per-seat plans
- Usage, prorations and one-time purchases count as revenue, never as MRR, so your MRR line only moves when subscriptions do
- Net revenue is each order minus tax and Polar's fee, and refunds are recorded against the order they reverse
- Cancellations churn when paid access ends, not when the button is clicked
- Orders in other currencies are converted at the rate on the order's date
Then it goes past MRR. The MRR breakdown shows new, expansion, contraction, churned and reactivated MRR month by month, and custom dashboards let you put the numbers you care about on one screen.
The part Polar's own dashboard can't do is attribution. Add the Chartsy script to your website and Chartsy follows each customer from first visit to signup to paid Polar order. With Polar checkout links there is no code at all: point the link's success URL at a page on your site ending in ?checkout_id={CHECKOUT_ID}, and Chartsy credits the order to the visit that brought the buyer. If you create checkouts from your server, pass the visitor id in the checkout metadata and Polar copies it onto the order. The full setup is in the Polar revenue attribution guide.
Key strengths:
- Connects in a couple of minutes, with webhooks added automatically
- Seat-aware MRR, with usage and one-time revenue kept out of it
- Net revenue after tax and Polar's fee
- Revenue by marketing channel, from first visit to paid order
- Combines several Polar organizations, plus Stripe, Paddle, Freemius, Creem.io and Lemon Squeezy, in one view
- GDPR mode keeps customer emails, names and locations out of the sync
- Pricing from $9/month, 14-day trial, no card required
Fact card:
- Pricing: Starter from $9/mo, Growth from $29/mo, priced on tracked website visits and signups rather than revenue, as of October 2026 (pricing)
- Free tier or trial: 14-day trial, no card
- Polar connection: Native, with an Organization Access Token; webhook added automatically
- AI and MCP: In-app chat and chart builder, plus a read-only MCP server with 19 tools for Claude, ChatGPT, Cursor and other clients
- Not ideal for: Founders who want Polar's own definitions, such as paused or past-due subscriptions counted in MRR or checkout conversion. Also not for anyone who needs automated dunning, CRM-style customer profiles or a data-warehouse export.
Where it fits: Polar-billed founders who want MRR they can trust and want to know which channels actually bring paying customers.
2. Polar's Built-In Analytics - Best for Zero Setup
Polar ships analytics inside its dashboard, so there is nothing to connect. According to Polar's documentation, it covers MRR and committed MRR, trial MRR, new and renewed subscriptions, ARPU and LTV, cancellations with churn rate and cancellation reasons, one-time product revenue, checkout conversion and net revenue. With Cost Insights turned on, it also shows costs and gross margin.
Key strengths:
- Included with Polar, no setup
- Good coverage of subscription, order and checkout numbers
- Cancellation reasons next to churn
Limitations:
- Polar data only - no way to add Stripe, Paddle or another billing account
- No view of which marketing channels or campaigns brought paying customers
- Dashboards are fixed; you can't build your own around the questions you care about
- Each organization is reported on its own
It's also worth knowing that metric definitions differ between tools. Polar's docs say paused and past-due subscriptions count toward its MRR until they actually end, so its MRR can read differently from a tool that counts only paid periods.
Fact card:
- Pricing: Included with Polar
- Free tier or trial: Included
- Polar connection: Built in
- AI and MCP: None that we could find documented for analytics
- Not ideal for: Founders with a second billing provider or several organizations, or anyone who wants revenue by marketing channel.
Where it fits: Early-stage founders with a single Polar organization who just want the headline numbers.
3. ChartMogul - Best for Teams Already Using It With Other Billing Systems
ChartMogul is a mature subscription analytics platform with strong cohort reports and customer profiles. It has native connectors for billing systems such as Stripe, Chargebee and Recurly, and connects Paddle through SaaSync, a third-party connector. At the time of writing we could not find a native Polar connector, so Polar data would have to come in through ChartMogul's Import API or a third-party sync service.
Key strengths:
- Deep cohort and retention reporting
- Customer-level profiles and segmentation
- Familiar to investors and finance teams
Limitations:
- Getting Polar data in means building or paying for an import
- More setup and a higher price than founder-focused tools as you grow
- No website-to-revenue attribution
Fact card:
- Pricing: Free up to $10K MRR, then Starter from $69/mo and Pro from $119/mo on monthly billing, as of October 2026 (pricing)
- Free tier or trial: Free plan under $10K MRR; 14-day trial, no card
- Polar connection: No native connector found; Import API or a third-party sync
- AI and MCP: ChartMogul AI assistant in-app, and a read-only MCP server
- Not ideal for: Polar-only founders without engineering time, and anyone who wants revenue by marketing channel.
Where it fits: Teams that already use ChartMogul for other billing systems and have the engineering time to push Polar data into it.
4. The Polar API Plus a Spreadsheet or BI Tool - Best for Full Control
Polar has a well-documented API and webhooks, so you can pull orders and subscriptions into a spreadsheet, a database or a BI tool such as Metabase and calculate everything yourself.
Key strengths:
- Full control over every definition
- Can be joined with any other data you hold
Limitations:
- You have to write the MRR logic yourself - seats, usage, prorations, refunds, currency conversion and cancellation timing
- Someone has to maintain it as Polar's API changes
- Easy to get subtly wrong, and hard to notice when you do
Fact card:
- Pricing: Free, apart from your time and any BI tool you pay for
- Free tier or trial: Free
- Polar connection: API and webhooks
- AI and MCP: Whatever your BI tool offers
- Not ideal for: Teams without someone to build and maintain the MRR logic.
Where it fits: Teams with a data engineer and unusual reporting needs.

How to Choose
If you want MRR you can trust and to see which channels bring paying customers: Chartsy - connect Polar in a couple of minutes and add one script to your website.
If you have one Polar organization and only need headline numbers: Polar's built-in analytics is a fine place to start.
If you bill through Polar and another provider: pick a tool that connects both natively, or your combined MRR will be a spreadsheet exercise every month. See how to combine revenue from multiple payment providers.
If you're still deciding on Polar at all: read Polar vs Stripe first. The billing platform you choose shapes how clean your revenue data is later.
Why Polar MRR Is Easy to Get Wrong
Polar makes it easy to sell in several ways from one account, which is great for the business and awkward for reporting. The most common mistakes we see:
- Counting usage charges as MRR, so MRR spikes in heavy months and drops in quiet ones
- Counting a per-seat subscription once, at the base price
- Using gross order amounts, including tax that was never yours
- Dropping a customer from MRR the moment they cancel, weeks before their access ends
- Adding up totals across currencies without converting them
Each of these changes the trend line, and the trend line is what you use to make decisions. Chartsy's approach is described in How We Calculate MRR at Chartsy, and exactly what is synced from Polar is listed in the Polar data models.
Frequently Asked Questions
What is the best analytics tool for Polar.sh?
For clear MRR plus revenue by marketing channel: Chartsy. For a free view of headline numbers with no setup: Polar's built-in analytics. For teams already on ChartMogul with engineering time to import data: ChartMogul via its Import API.
Does Polar have built-in analytics?
Yes. Polar's dashboard covers MRR, subscriptions, churn and cancellation reasons, orders, checkouts and net revenue. It doesn't show which marketing channels brought paying customers, and it can't combine Polar with other billing providers.
How does Chartsy count Polar seats and usage billing?
Per-seat plans count every seat toward MRR. Usage charges, prorations and one-time purchases count as revenue but never as MRR, so your MRR only changes when subscriptions do.
Can I track which marketing channels bring Polar customers?
Yes, with Chartsy's website script. Use a checkout link success URL ending in ?checkout_id={CHECKOUT_ID}, or pass the visitor id in your checkout metadata, and each paid order is credited to the visit that brought the buyer. See the Polar revenue attribution guide.
Can I combine several Polar organizations, or Polar and Stripe?
Yes. Each Polar organization is connected as its own source, and Chartsy adds them up together with any Stripe, Paddle, Freemius, Creem.io or Lemon Squeezy accounts you connect.
Is it safe to connect Polar to an analytics tool?
Yes, if the tool asks only for the access it needs. Chartsy asks for read scopes plus one scope to create its webhook, and GDPR mode keeps customer emails, names and locations out of the sync. See Is It Safe to Connect Stripe or Paddle to an Analytics Tool? for what to look for in any tool.
