Revtrail vs PostHog
PostHog gives away a million events a month and throws in session replay, feature flags, experiments, surveys, and error tracking. On raw value per dollar, that's a hard offer to argue with. It's also aimed at a different question than ours.
Revtrail vs PostHog, feature by feature
| Capability | Revtrail | PostHog |
|---|---|---|
| Primary question | Which acquisition channel produced revenue? | What are users doing inside the product, and why? |
| Setup | One script tag. Events optional. | An SDK plus an event taxonomy you design and maintain, though autocapture gets you started. |
| Free tier | None. 14-day trial. | 1M product-analytics events a month, free, indefinitely. |
| Session replay, flags, experiments | None of them. | All of them, metered separately. |
| Revenue attribution | The product. Payments join the visitor's first-touch journey and every channel is ranked by the money it produced. | Revenue analytics exist, driven by the events and properties you send. |
| Cookies and consent | Cookieless by default; no banner needed for our tracking. | Uses cookies for identification by default, which for most EU deployments means a consent banner. |
PostHog pricing: Usage-based with no base fee: the first 1M product-analytics events each month are free, then roughly $0.00005/event descending with volume, with replay, flags, and surveys metered separately. Read off their own pricing page in August 2026 — check it before you decide, because plans move and we don't control that page.
These tools answer different questions
PostHog is a product-analytics platform: it's excellent at telling you that users who complete step three retain at twice the rate, and at letting you ship a flag to test whether step three can be removed. Revtrail is a marketing-attribution tool: it tells you that the Reddit thread produced four customers worth $2,400 and the paid campaign produced twelve worth $600. Most teams eventually want both answers. Very few need one tool to give them both.
The free tier is genuinely generous, and the taxonomy is the cost
A million events a month covers a lot of startups for a long time, and the bill only starts when you're already succeeding. The real cost of product analytics isn't the invoice — it's the event taxonomy. Somebody has to decide what gets tracked, name it consistently, keep it consistent as the product changes, and clean up when it drifts. That's ongoing work that a script tag doesn't ask of you.
The cookie banner difference
PostHog identifies users with cookies by default, which in most EU deployments puts it behind a consent banner along with everything else. Revtrail's default identity is a daily rotating hash with no cookie and no cross-site identifier, so our tracking doesn't require consent. If you're running PostHog anyway, this is a reason to keep a cookieless tool for the top-of-funnel numbers: you'll be counting the visitors who declined.
Running both, deliberately
The clean split is PostHog inside the product, Revtrail in front of it. Revtrail tells you which channels are worth more money; PostHog tells you why the users from those channels do or don't stick. If you must run one, pick by which question is currently costing you more: unclear acquisition spend, or unclear product behaviour.
So which one should you use?
Run PostHog if your open questions are about product behaviour, or if the free tier is decisive and you're happy to own an event taxonomy. Run Revtrail if your open question is where the marketing budget should go, and you want that answered by a script tag and a Stripe webhook rather than by an instrumentation project.
Questions people actually ask
- Does PostHog do revenue tracking?
- Yes, driven by the events and properties you send. The difference is architectural: our revenue comes only from verified payment webhooks and rolls into first-touch lifetime value per channel.
- Is PostHog cheaper than Revtrail?
- Below a million events a month, PostHog's product analytics is free and we cost $9/mo, so yes. Above that it's usage-based and the comparison depends on volume and which of their products you enable.
- Can I use both without double-counting?
- They're separate tools with separate dashboards, so there's nothing to double-count. Expect their visitor numbers to differ — different identity models, different consent behaviour, different bot filtering.
