Whether to buy EspoCRM Cloud per user or run the free AGPL edition yourself: cloud plan limits, US and German server locations, and how the per-instance, time-limited licenses for paid extensions such as the Advanced Pack and Sales Pack change the cost of self-hosting.
A standalone CRM (AGPL-3.0) against the CRM app inside the Odoo suite: when CRM alone is the need, when ERP integration tips the choice, and which features need Odoo Enterprise or EspoCRM paid extensions.
Two self-hosted PHP CRMs compared: licenses (AGPL-3.0 versus the MPL-based Vtiger Public License), entity customization, workflows, extensions and the commercial editions behind each.
Two lighter self-hosted CRMs with different foundations: EspoCRM's PHP core and paid Advanced and Sales Packs against Frappe CRM on the Frappe Framework with ERPNext integration and per-site cloud pricing, with a verdict by need.
Two PHP CRMs for smaller teams: EspoCRM's AGPL-3.0 core with OIDC and LDAP sign-in and paid workflow extensions against Krayin's MIT-licensed Laravel CRM with paid extensions and hosting, compared on features, requirements and support.
The modern lightweight shortlist: a PHP CRM, a TypeScript CRM on PostgreSQL and a Frappe Framework CRM, compared on license, what is free when self-hosted, SSO, stack and release pace, with a pick by team.

The Docker-based installation script with Nginx, MariaDB and a backup and upgrade utility against a manual install on your own web server and database: control, upgrades, backups and when each fits.
Which database to run EspoCRM on: the supported MySQL, MariaDB and PostgreSQL versions, what the install script assumes, and how existing database skills, backups and HA tooling should decide.
Cost side by side: both free to self-host, EspoCRM Cloud's per-user plans with the Advanced Pack included against Twenty's per-user plans that gate SSO and audit logs, plus hosting and support effort for each.
