PostHog alternatives

13 tools we tested head to head against PostHog, ranked — and what each one actually does differently.

last reviewed 4 aug 2026 · from our best 14 session replay tools ·list curated by Onur Ozcanxin

first — what you'd be leaving

PostHog ranks #3 of 14 in our session replay tools testing. masks all inputs by default, hosts in the eu on every plan including free, and you can self-host the mit core..

84/100

the best combination of correct defaults, real eu hosting and an escape hatch, if you can live with an enterprise carve-out in the licence.

why people look for an alternative
  • `ee/` directory is proprietary — the open core is not the full product
  • free-plan retention capped at 1 year until billing is attached
  • consent-gating behaviour undocumented
  • mobile replay billed separately at double the entry rate

stay with PostHog if `maskAllInputs: true` by default, with the reasoning documented is the thing you care about most — nothing below beats it on that.
