Comparisons/Free alternatives
Free Mixpanel alternatives by actual product need
Start with Mixpanel Free if 1 million monthly events, 10,000 session replays, and limited experimentation cover the job. Consider PostHog for usage-based analytics plus replay, Amplitude for a broad free product platform, or GrowthBook when experimentation and self-hosting matter more than an all-in-one analytics suite.

The current decision
What are you actually replacing?
You need product analytics, replay, or experimentation under a budget constraint and want to know whether Mixpanel Free already fits.
Mixpanel currently has a free forever plan. The useful decision is whether its event, replay, experimentation, and feature-flag allowances fit your product, or whether another operating model is a better match.
Free means different things
A permanent free tier, a limited free plan, and a temporary trial are different buying propositions. This page keeps those states separate.
Decision matrix
Which option fits the constraint?
| Product | Free status | Free allowance | Analytics fit | Operational constraint | Best fit |
|---|
| Mixpanel Free | Free tier with limits | Free forever with unlimited seats, up to 1 million monthly events, 10,000 monthly session replays, up to 1,000 monthly experiment users, and 10 active feature flags. | Product analytics, Funnels and retention, Session replay, Feature flags, Experiments | Event, replay, experiment, and feature-flag volumes have separate limits. Saved reports and advanced scale requirements may require a paid plan. | A product team whose event volume and replay needs fit the published free allowances. |
|---|
| PostHog | Free tier with limits | Published free tiers include 1 million product analytics events per month and 5,000 session replay recordings per month, with separate usage-based products. | Product analytics, Session replay, Feature flags, Experiments, Warehouse options | Each product has its own allowance and usage-based pricing after the free tier. The broader platform may require more implementation decisions than a focused analytics tool. | Technical product teams that want analytics, replay, flags, and experiments in one usage-based platform. |
|---|
| Amplitude | Free tier with limits | Free plan includes 2 million events per month, 10,000 monthly session replays, and access to a broad platform with limited capabilities in some products. | Product analytics, Session replay, Experimentation, Feature flags, Guides and surveys | Some advanced analysis, retention, and experimentation capabilities are limited by plan. A broad platform can increase setup and governance choices. | Teams that want product analytics connected to a wider activation and experimentation platform. |
|---|
| GrowthBook self-hosted | Open source / self-hosted | GrowthBook documents a free self-hosted path with unlimited users, unlimited feature flags, and unlimited experiments. | Experimentation, Feature flags, Warehouse-oriented analysis, Self-hosting | It is not a general drop-in product analytics replacement. Self-hosting requires engineering ownership. | Teams whose central need is experimentation and flag control rather than turnkey product analytics. |

This is a fit guide, not a ranking. The right choice depends on the evidence you need and the constraint you cannot ignore.
Evidence and tradeoffs
What each option can and cannot replace
What is free
Free forever with unlimited seats, up to 1 million monthly events, 10,000 monthly session replays, up to 1,000 monthly experiment users, and 10 active feature flags.
Capabilities
Product analytics, Funnels and retention, Session replay, Feature flags, Experiments
Important limits
- • Event, replay, experiment, and feature-flag volumes have separate limits.
- • Saved reports and advanced scale requirements may require a paid plan.
Fit and boundary
A product team whose event volume and replay needs fit the published free allowances. The incumbent may already be the lowest-friction answer. Switching is only useful when a capability or operating constraint is more important than familiarity.

- Mixpanel pricing: Free forever plan with unlimited seats, up to 1 million monthly events, 10,000 monthly session replays, up to 1,000 monthly experiment users, and 10 active feature flags.
What is free
Published free tiers include 1 million product analytics events per month and 5,000 session replay recordings per month, with separate usage-based products.
Capabilities
Product analytics, Session replay, Feature flags, Experiments, Warehouse options
Important limits
- • Each product has its own allowance and usage-based pricing after the free tier.
- • The broader platform may require more implementation decisions than a focused analytics tool.
Fit and boundary
Technical product teams that want analytics, replay, flags, and experiments in one usage-based platform. A broad alternative when the operating model fits. It is not automatically a better answer for a low-volume team already served by Mixpanel Free.

- PostHog product and usage pricing: 1 million product analytics events per month and 5,000 session replay recordings per month on the free tier.
What is free
Free plan includes 2 million events per month, 10,000 monthly session replays, and access to a broad platform with limited capabilities in some products.
Capabilities
Product analytics, Session replay, Experimentation, Feature flags, Guides and surveys
Important limits
- • Some advanced analysis, retention, and experimentation capabilities are limited by plan.
- • A broad platform can increase setup and governance choices.
Fit and boundary
Teams that want product analytics connected to a wider activation and experimentation platform. Strong when the wider platform matters. It is not a narrow drop-in replacement for every Mixpanel report or event taxonomy.

- Amplitude pricing: Free plan with 2 million events per month, 10,000 monthly session replays, and limited experimentation, guides, and surveys.
What is free
GrowthBook documents a free self-hosted path with unlimited users, unlimited feature flags, and unlimited experiments.
Capabilities
Experimentation, Feature flags, Warehouse-oriented analysis, Self-hosting
Important limits
- • It is not a general drop-in product analytics replacement.
- • Self-hosting requires engineering ownership.
Fit and boundary
Teams whose central need is experimentation and flag control rather than turnkey product analytics. A capability-specific alternative, not a promise to replicate Mixpanel’s full product analytics surface.

- GrowthBook pricing: Free Cloud Starter plan with up to 3 users, unlimited feature flags and experiments, plus a free self-hosted path.
Startup guidance
What changes when budget and sample are small?
- • Estimate event volume and replay volume separately. A plan that fits events can still exceed its replay allowance, or the reverse.
- • Keep the incumbent if the current free plan answers the product questions and the team already trusts its instrumentation. Migration has a real opportunity cost.
- • Choose a broader platform only when the added capabilities justify added setup, governance, or vendor complexity.
When not to switch
The free option is not always the right option
- • Stay with Mixpanel Free when its published allowances fit the workload and the team does not need a different deployment or pricing model.
- • Do not adopt product analytics to answer a landing-page diagnosis question. Event and replay data can show behavior, but it does not independently determine which page condition should change.
Where Nebula fits
Evidence about behavior is not diagnosis
Product analytics explains events and journeys inside a product. Nebula audits a public landing page for observable conversion conditions. Those are complementary evidence sources, not interchangeable products.
