Vexo vs PostHog: Pricing Comparison for Mobile Analytics
What a mobile app actually pays once analytics and mobile session replay are both metered
August 2, 2026
Jump to section
PostHog is a broad, developer-loved platform — analytics, session replay, feature flags, experiments, error tracking, surveys, and a data warehouse, each metered on its own. Vexo is narrower on purpose: a mobile-first tool that bundles analytics, session replay, and heatmaps into one flat plan built for React Native and Expo. The pricing philosophies diverge sharply — PostHog is usage-based per product, Vexo is a single flat monthly rate.
This post compares both, tier by tier, using each vendor's current public pricing. Vexo's numbers come straight from our own pricing page; PostHog's come from their published pricing page. Figures are accurate as of August 2026 — always confirm the live pages before budgeting, since plans change.
How the two models differ
PostHog charges per product, per unit, after a monthly free allowance on each. Product analytics is billed per event (starting at $0.00005/event above the first 1M), and session replay is billed per recording — with a separate, higher rate for mobile replay (starting at $0.01/mobile recording above the free 2.5K) versus web replay ($0.005/recording above the free 5K). Every product you turn on adds its own line to the bill. Rates decline as volume grows.
Vexo is flat-rate: you pick an event tier and pay a fixed monthly price that already includes session replays (mobile-native), unlimited heatmaps, and your seats. No per-product meters, no surprise overage line at the end of a busy month.
Free tier
| Free plan | Vexo (“Try it out”) | PostHog (Free) |
|---|---|---|
| Monthly events | 500k | 1M |
| Session replays | 100 included | 5k web + 2.5k mobile |
| Heatmaps | Included | Included (web-oriented) |
| Seats | 2 free seats | Unlimited |
Both free tiers are usable for a small app or a development phase. PostHog's per-product free allowances are generous (1M events, plus 2.5K free mobile replays), and it's unlimited seats. Vexo's free tier is smaller on events but is mobile-native end to end — heatmaps and replay are built for React Native rather than adapted from a web-first product.
Paid plans
Vexo's Premium plan uses a simple slider — you pick an event tier and get session replays included at every step. Prices are flat monthly rates with no per-event overage; your first 500k events each month are free:
| Vexo Premium tier | Session replays | Monthly |
|---|---|---|
| 1M events | 4,000 | $15 |
| 2.5M events | 10,000 | $60 |
| 5M events | 20,000 | $135 |
| 10M events | 40,000 | $285 |
| 25M events | 100,000 | $615 |
| 50M events | 200,000 | $1,165 |
Every Premium tier includes unlimited heatmaps, 2 seats, and full access to all features. Extra seats are $4.90 each.
PostHog has no fixed “plan price” — your bill is the sum of what each product meters. For a mobile app the two lines that matter most are product analytics (per event) and mobile session replay (per recording, at the higher mobile rate). Here are the top PostHog rate bands as published:
| PostHog product | Free / month | Starting rate above free |
|---|---|---|
| Product analytics | 1M events | $0.00005/event (declines with volume) |
| Session replay (web) | 5k recordings | $0.005/recording (declines with volume) |
| Session replay (mobile) | 2.5k recordings | $0.01/recording (declines with volume) |
A worked example
Take a React Native app doing 5M events/month that wants session replay on. With Vexo, that's the 5M Premium tier: a flat $135/month, with 20,000 replays and unlimited heatmaps included.
With PostHog, you add up the meters. Product analytics: 5M events minus the 1M free = 4M billable. At the published $0.00005 starting rate that would be $200, but PostHog's per-event rate declines as volume grows, so the real analytics line lands lower — on the order of $150/month. Then add mobile replay: 15,000 recordings minus the 2.5K free = 12,500 billable at $0.01 ≈ $125/month. That's roughly $275/month combined — before feature flags, error tracking, or any other product you enable — versus Vexo's flat $135 (which also includes more replays, 20K). PostHog's higher-volume bands are cheaper per unit, so the gap narrows at scale, and if you use PostHog's other products heavily the per-product model can be worth it; the exact numbers depend on your replay volume, so confirm against the live calculator.
Enterprise
Vexo's Enterprise plan covers 1+ billion events and 1+ million replays with 10 seats included, onboarding, and custom configuration — priced via Contact Us. PostHog stays on its usage-based model at scale (with volume discounts baked into the declining rate bands) and offers a platform add-on and billing limits for larger teams; there is no separate fixed “enterprise price” on its public page, so confirm add-on and support terms directly.
Which should you choose?
If you run a React Native or mobile app, want mobile-native session replay and heatmaps included, and value a predictable bill that doesn't move with usage, Vexo is the simpler choice. If you want PostHog's breadth — analytics plus flags, experiments, error tracking, warehouse — and are comfortable metering each product (and watching the mobile-replay line, which is priced above web replay), PostHog is a powerful, developer-friendly platform.

Frequently Asked Questions
Does Vexo charge separately for session replay?
No. Session replays are included in every Vexo plan, with the number scaling up as you move through the Premium event tiers. There is no separate per-replay meter.
How does PostHog bill for mobile session replay?
PostHog meters mobile session replay separately from web replay, at a higher starting rate — about $0.01 per mobile recording above the free 2.5K/month, declining as volume grows. Product analytics is billed separately per event. Your total bill is the sum of every product you enable, so confirm each meter on PostHog's live pricing calculator.
Does Vexo charge overage fees if I exceed my tier?
No. Vexo is flat-rate: you pick an event tier and pay one fixed monthly price with session replays and heatmaps included — there is no per-event overage line at the end of a busy month. Your first 500k events each month are free, and if you consistently outgrow a tier you simply move up to the next one.
