Mixpanel
Mixpanel is a product analytics tool: it records the events people trigger in your app or site and turns them into funnels, retention curves and user paths, with session replay, heatmaps, experiments and feature flags on the same data.
It suits founders who want to answer product questions themselves, or hand them to a teammate, without writing SQL.
It is free up to 1 million events a month with unlimited seats; above that, Growth bills by the event, $140 a month for 1.5 million, as checked on 30 October 2026.

- What it does
- Event analytics for funnels, retention and user paths, with session replay, experiments and feature flags on the same events, and no SQL needed.
- Our take
- Founders who want to answer product questions themselves, or hand them to a teammate, without SQL. Track the events that matter, build a funnel or retention report in the interface, and ask the same questions from Claude, ChatGPT or Cursor through Mixpanel's MCP server.
- Pricing
- FreemiumFree: up to 1 million events and 10,000 session replays a month, unlimited seats, 5 saved reports per seat and cohorts you can build but not save. Growth has no base fee: the first million events are free, then billed by volume, $140 a month for 1.5 million events, $613 for 5 million and $2,289 for 20 million when billed monthly, or $100, $438 and $1,635 a month billed yearly, as checked on 30 October 2026. On the 1-million plan, each event above it is $0.00028. Growth includes 20,000 replays a month, unlimited saved reports and cohorts, and data warehouse connectors; Group Analytics and Data Pipelines cost extra. On Free, reports lock at 1 million events until you upgrade or the month resets; on Growth, overage is charged the next month, and Mixpanel offers no billing limit. Companies under 5 years old with up to $8M raised get their first year free on the Startup Plan.
The IndieHacked breakdown
What it does
Mixpanel tracks events, the actions people take in your product such as Signed Up or Purchase Completed, and builds insights, funnels, retention, flows and cohorts from them, including web and mobile analytics and campaign reporting. You install an SDK and track events by hand, or turn on autocapture; data can also arrive from a CDP or from Snowflake, BigQuery and other warehouses through its connectors. Session replay, heatmaps, experiments and feature flags run on the same events.
The Mixpanel Agent answers questions in plain language inside the product on every plan. The MCP server reads and writes: from Claude, ChatGPT, Cursor or Codex you can query reports, build a dashboard or launch an experiment, within the permissions you already have, and Mixpanel Headless exposes the same in a Python SDK. Data sits in the US or the EU, chosen when you create a project, and is kept 2 years by default.
Who it suits
Founders who want to answer product questions without SQL: where a signup drops out, which feature brings users back, which channel sends the customers who stay. Reports are built in the interface, without a query language, seats are unlimited on every plan, and Mixpanel describes the typical Growth customer as a team of fewer than 50.
It fits a startup that expects to grow into it. The first year is free on the Startup Plan for companies under 5 years old with up to $8M raised, with 1 billion events and 1 million replays, and the Growth plan's first million events stay free after that. Mixpanel's comparison with PostHog makes its case on staying with one provider from day one to IPO.
Not the right fit for
Founders who want a hard cap on the monthly bill. On Growth, events above the plan are charged the next month, and Mixpanel's docs say a billing limit is not possible; its alerts arrive at 85% and 100% of plan volume and above. PostHog, reviewed here, lets you set a dollar limit per product and stops taking data there.
Developers who want error tracking in the same tool as their analytics. Mixpanel's plans cover analytics, replay, experiments and feature flags and list no error tracking; PostHog, reviewed here, puts errors next to the replay, and Sentry, reviewed here, is built for errors and traces.
