The short version

  • Each has a real cost: Apollo.io everything is metered in credits, and the free Starter plan runs on them too, so prospecting volume is capped rather than the feature set; 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.
  • They diverge on capability: Apollo.io covers Contact database, EspoCRM covers Entity manager.
  • 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.

Apollo.io

  • Everything is metered in credits, and the free Starter plan runs on them too, so prospecting volume is capped rather than the feature set
  • Plans described as unlimited are capped in the fair use policy at 10,000 credits a month for non-paying accounts
  • Connecting a mailbox that is not Gmail or Microsoft requires a paid plan
  • How many records can be selected at once varies by tier
  • Running out of credits means buying more rather than waiting for a reset

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.

Answered from the vendors’ own pages

Apollo.io: Does Apollo offer a free plan?

Yes, Apollo offers a Starter plan that is free forever and includes unlimited email addresses for contacts. Gmail and Microsoft email account linking are available on the free plan with limited third-party email account linking.

Source
EspoCRM: Is the self-hosted version really full featured?

The core CRM is, but several paid extension packs including Advanced Pack for reports and BPM are sold separately as one-off purchases and are not in the free download.

Apollo.io: How does Apollo's credit system work?

Apollo uses a credit-based system for exporting contact data outside the platform. Free and non-paying accounts have a monthly credit limit of 10,000 credits. Paid accounts receive limits based on their plan pricing, calculated as the lesser of annual commit divided by $0.025 or 1 million credits annually.

Source
EspoCRM: What are the cloud seat minimums?

Three users on Basic, five on Enterprise and ten on Ultimate, so the advertised per-user rate is not the smallest bill you can pay.

Apollo.io: How much do trial plans cost on Apollo?

Apollo trial plans include 50 credits and 5 mobile credits to test paid features at no charge. Trial versions do not support non-Gmail/Microsoft email account linking. Upgrades take effect immediately while downgrades take effect at the end of the billing cycle.

Source
EspoCRM: What does it need to run?

PHP, MySQL or MariaDB and a web server. It installs on ordinary shared hosting or a small VPS, which is unusual for a modern CRM.

EspoCRM: Can I move from cloud to self-hosted later?

Yes. EspoCRM states customers own their database and data files, so an export and reinstall is possible, though you take on all maintenance when you do.
