  • They diverge on capability: EspoCRM covers Entity manager, PostHog covers Product analytics.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

EspoCRM

  • The AGPLv3 licence obliges you to publish source modifications if you make the modified software available over a network, which blocks resellers who want to offer a customised hosted version without opening their code.
  • Cloud plans carry seat minimums of three, five and ten users, so a two-person consultancy pays for three seats and a small team wanting the Ultimate features pays for ten.
  • Record ceilings are real on the cheaper cloud tiers, with Basic capped at 100,000 records, and hitting the cap means a tier upgrade rather than a small overage charge.
  • Marketing automation, sequences and native telephony are thin compared with HubSpot or Zoho, so most deployments end up wiring in a separate mailing tool and a separate dialler.
  • Self-hosting shifts the entire cost to your own team: PHP version upgrades, database backups and security patching are yours, and a neglected instance becomes an internet-facing liability holding your customer list.

PostHog

  • The free tier covers 1M events, 5K web session recordings and 2.5K mobile recordings per month before usage-based billing starts
  • Accounts without a card on file are limited to 1 project; adding one raises it to 6
  • Data retention is 1 year until a card is added, which extends it to 7 years
  • Support is community-only until the account is on a paid plan
  • Error tracking is capped at 100K exceptions and surveys at 1500 responses per month on the free tier
