My honest take

My honest take: PostHog for most founders, full stop. 88 vs 73 is a 15-point gap, and gaps that wide usually mean the loser has fundamental issues (pricing, ownership risk, or a missing capability) that show up later. Amplitude can still be the right call in narrow situations (enterprise product analytics), but if you're picking a primary tool, default to PostHog and don't second-guess.

The long answer

Why PostHog wins.

PostHog is product analytics, session replay, feature flags, a/b testing, all open source. Amplitude is enterprise product analytics. Both target analytics workflows, and the question we get most often is which one to commit to. Here is the honest answer based on our scoring across functionality, pricing value, ease of use, reliability, and founder fit.

PostHog wins clearly. 88 vs 73: a 15-point gap on Best Score. Across the five criteria we weight (functionality, pricing value, ease of use, reliability, founder fit), PostHog leads on most. Amplitude is still defensible if you fit one of the specific use cases below, but for a generalist founder it is the harder sell.

Where the gap shows up specifically: Pricing value: PostHog (9/10) better value for what you pay than Amplitude (7/10). Founder fit: PostHog (9/10) a better fit for solo and small-team founders than Amplitude (7/10). These are the differences that actually change a buying decision once you have used both for a real project.

On the ownership side, PostHog is founder-led (lower stack risk). We weight ownership in Stack Score because it predicts pricing trajectory and continuity risk over 2-3 year horizons. Founder-led usually means slower price creep and more product continuity; PE-owned usually means the opposite.

FAQ

PostHog vs Amplitude: the common questions.

Which is better for solo founders?

PostHog scores higher on founder fit (9/10 vs 7/10), meaning it is better tuned to small-team and solo workflows: lighter setup, fewer enterprise-only features locked behind upgrades, more sensible pricing tiers for one-person use.

Which is cheaper at the founder tier?

PostHog pricing model: Freemium. Amplitude pricing model: Freemium. PostHog scores higher on pricing value overall (9/10 vs 7/10).

Is the ownership situation a risk for either tool?

PostHog is founder-led: usually slower price creep and more product continuity over a 2-3 year horizon. Amplitude has standard ownership signals.

What's the migration cost if I'm already on the other one?

Migration cost depends on how deep you've integrated this category into your stack. For a project that uses PostHog or Amplitude as the primary surface (not just a small embedded feature), expect a half-day to a weekend of migration work plus a week of running both in parallel. Both tools support data export. Run a fresh audit on your current stack before deciding the switch is worth it: audit my stack with both options.

How is this scoring decided?

Best Score is 70% Category Fit (graded on functionality, pricing value, ease of use, reliability, founder fit, scored 0-10 each) plus 30% Stack Score (editorial verdict + ownership stability + pricing trajectory). Same formula on every tool, no paid placements. Read the full methodology.

Real-world scenarios

Which one wins in your specific situation.

  1. You're a solo founder shipping your first product: PostHog is the cleaner choice. Less setup, fewer enterprise-only features locked behind upgrades, pricing that makes sense for one seat.
  2. You already use PostHog and it's working: don't migrate. The score gap (15 points) doesn't justify the disruption. Migration costs are real · half a day to a weekend of work plus a week running both in parallel.
Stack fit

How each fits inside a founder stack.

A tool you can't integrate is a tool you'll replace in six months. Here's how each plays with the rest.

PostHog

PostHog fits cleanly in a stack with Vercel, Stripe, Linear, Resend. If your stack already includes most of those, PostHog integrates without friction.

Amplitude

Amplitude fits the same kind of stack. If your existing stack leans toward Vercel or Stripe or Linear, Amplitude doesn't create integration debt either.

Final recommendation

For most founders, PostHog. The gap is wide enough that the loss-of-points reasons matter more than the win-points reasons. Default to PostHog unless you fit a specific edge case. If you're already on Amplitude and it's working, don't migrate. The cost of switching is real and the gain is small.

Bottom line

PostHog for most founders.

PostHog wins clearly. 88 vs 73: a 15-point gap on Best Score. You have real users and need to understand behaviour. Amplitude is still a defensible choice if enterprise product analytics, but for most founders PostHog is the safer pick.
