The short version

  • Only EspoCRM has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; Really Simple Systems the vendor's own pricing page as captured by the Internet Archive on 22 October 2019 listed four CRM tiers billed annually: Free at $0 for up to 2 users, Starter at $14 per user per month, Professional at $30 per user per month, and Enterprise at $46 per user per month (each roughly 7 to 10 percent higher if billed monthly); the Marketing add-on was $22 per month for up to 5,000 emails and Advanced Marketing scaled to 50,000 emails per month, though this capture is over five years old
  • They diverge on capability: EspoCRM covers Entity manager, Really Simple Systems covers Contact management.
  • 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.

Really Simple Systems

  • The vendor's own pricing page as captured by the Internet Archive on 22 October 2019 listed four CRM tiers billed annually: Free at $0 for up to 2 users, Starter at $14 per user per month, Professional at $30 per user per month, and Enterprise at $46 per user per month (each roughly 7 to 10 percent higher if billed monthly); the Marketing add-on was $22 per month for up to 5,000 emails and Advanced Marketing scaled to 50,000 emails per month, though this capture is over five years old

Answered from the vendors’ own pages

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.

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.

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.
