Short answer

Choose Chartsy if

  • Your main question is which channels bring paying customers and MRR
  • You bill through Paddle, Freemius, Creem.io or Lemon Squeezy
  • You want MRR and attribution working without modelling data or wiring events
  • You want a flat monthly price and cookieless tracking by default

Choose PostHog if

  • You need product analytics, session replay, feature flags, experiments or surveys
  • You want a data warehouse and SQL across all your data
  • You want a generous free tier or to self-host open source
  • You have engineers who will instrument events

PostHog can do far more than Chartsy, including revenue analytics from Stripe. Chartsy is the simpler choice when revenue and attribution are what you actually need.

PostHog details come from PostHog's pricing and revenue analytics docs, checked in October 2026. Disclosure: Chartsy is our product. Both tools get the same fact card and the same “not ideal for” line.

Why founders look elsewhere

PostHog does everything. Most founders only need one part of it.

PostHog is excellent for product teams. These are the reasons revenue-focused founders pick something narrower.

  • Revenue from more providersPostHog’s revenue analytics reads Stripe or events you send. Chartsy connects Paddle, Polar.sh, Freemius, Creem.io and Lemon Squeezy natively too, and adds them into one MRR.
  • Attribution without modellingIn Chartsy, MRR by channel works as soon as the script and billing are connected. In PostHog you link billing customers to persons and build the breakdown yourself.
  • A price you can predictPostHog bills each product by usage after its free allowance. Chartsy is one monthly price set by your tracked visits and signups.
  • Less to maintainNo SDK events to instrument and no warehouse views to model. Chartsy calculates MRR from your billing data using documented rules.
Fact cards

PostHog and Chartsy at a glance

Same fields for both tools, including what each one is not ideal for.

PostHog

Best for: Product and engineering teams that want product analytics, session replay, feature flags, experiments and a data warehouse in one platform.

PostHog is an open-source product platform. Alongside product and web analytics it offers session replay, feature flags, experiments, surveys, error tracking and a data warehouse with SQL. Its revenue analytics calculates MRR, ARR, ARPU, churn, expansion and LTV from a connected Stripe account or from revenue events you capture, and PostHog AI can answer questions about them.

Pricing
Free each month for the first 1,000,000 product analytics events, 5,000 session recordings, 1,000,000 feature flag requests, 1,500 survey responses and 1,000,000 warehouse rows. After that, per unit: for example $0.00005 per event from 1M to 2M. Optional platform packages from $250/mo.
Free tier or trial
Free plan, no credit card required.
Revenue sources
Stripe or your own revenue events for revenue analytics. Chargebee and Polar are available as data warehouse sources.
Hosting
PostHog Cloud, or self-hosted open source under the MIT licence.
AI
PostHog AI for natural-language questions about product and revenue data.
Not ideal for
Founders who only need MRR and attribution and don’t want to instrument events or model data, and sellers on Paddle, Freemius, Creem.io or Lemon Squeezy who want revenue connected natively.

Chartsy

Best for: SaaS founders who want an easy MRR dashboard and the marketing channel behind every paying customer.

Chartsy connects to Stripe, Paddle (Billing and Classic), Polar.sh, Freemius, Creem.io and Lemon Squeezy, syncs your last 24 months, and shows MRR, ARR, churn, LTV and NRR with an MRR breakdown. One website script adds visits, referrers, landing and signup pages, and MRR by marketing channel.

Pricing
Starter from $9/mo (10k events), Growth from $29/mo. Events are tracked visits (roughly one per session) and signups. (pricing)
Free tier or trial
14-day trial, no card. No free plan.
Revenue sources
Six billing providers natively, plus a Custom Billing API. MRR rules are documented in How We Calculate MRR.
Hosting
Hosted only.
AI and MCP
In-app chat (200 questions/mo on Starter, 2,000 on Growth) and a read-only MCP server with 19 tools.
Not ideal for
Teams that need product analytics, session replay, feature flags, experiments or a data warehouse, and anyone who wants to self-host.
Pricing

What each costs

PostHog is free up to generous monthly allowances and then charges per unit for each product you use. Chartsy is one monthly price based on tracked visits and signups.

500,000$59$109
1,000,000$79$149
  • An early SaaS within PostHog’s free allowances pays nothing for PostHog; Chartsy Starter is $9/mo.
  • PostHog costs climb with product usage, recordings and flags; Chartsy’s price only changes with tracked visits and signups.

Rule of thumb: if you’ll use PostHog’s product tools, its free tier is hard to beat. If you only need revenue and attribution, Chartsy is less to set up.

FAQ

Frequently asked questions

What is the best PostHog alternative for SaaS revenue?

For MRR, churn and MRR by marketing channel across Stripe, Paddle, Polar.sh, Freemius, Creem.io or Lemon Squeezy: Chartsy. For product analytics without the rest of the suite: Mixpanel. For privacy-first web analytics: Plausible.

Does PostHog track MRR?

Yes. PostHog’s revenue analytics calculates MRR, ARR, ARPU, churn, expansion and LTV from a connected Stripe account or from revenue events you capture. Other billing providers need events or a data warehouse source.

How much does PostHog cost?

PostHog is free each month for the first 1M product analytics events, 5,000 session recordings and 1M feature flag requests, then usage-based per product, for example $0.00005 per event from 1M to 2M. Platform packages start at $250/mo.

Can PostHog show revenue by marketing channel?

Not as a documented built-in report. You can build it by linking billing customers to PostHog persons and breaking revenue down by their acquisition properties. Chartsy shows MRR by channel, campaign and referrer once its script and your billing are connected.

Can I use PostHog and Chartsy together?

Yes. Use PostHog for product analytics, replay and feature flags, and Chartsy for MRR, churn and revenue attribution. Both run on your site without interfering.

Is Chartsy open source or self-hostable?

No. Chartsy is hosted only. If self-hosting is a requirement, PostHog is the better fit.
