Twenty

open sourcewebself-hosteddocker to self-host

A modern pipeline CRM with custom objects, views and mailbox sync; the subscription becomes a Compose file.

licenseAGPL-3.0

runsyour machine or their cloud

installHosted cloud signup or official one-line/Docker Compose self-host install

dataCRM records and configuration in PostgreSQL; files in local storage or S3-compatible object storage on the selected host

the catch vs CapsuleTwenty is more flexible but less mature around Capsule’s polished task, calendar, mobile, and small-business onboarding experience.

setupFree use requires Docker, at least 2 GB RAM, PostgreSQL-backed containers, secrets, and domain/TLS configuration

K

Krayin CRM

open sourcewebself-hostedself-host, real ops

A Laravel sales pipeline with leads, contacts and email; glossy enough, but it still wants a PHP stack.

licenseMIT

runsyour machine or their cloud

installComposer package, browser GUI installer, or Docker; managed cloud is also offered

dataCRM records in MySQL/MariaDB (Laravel database); uploads in storage/app/public on the chosen host

the catch vs CapsuleKrayin’s integrations, mobile experience, and overall maturity are behind Capsule’s finished small-business workflow.

setupThe free path requires PHP/Composer plus MySQL/MariaDB, or Docker and a server; HTTPS, backups, and updates remain yours

S

SuiteCRM

open sourcewebself-hostedself-host, real ops

The old-school full-fat CRM: every module you remember, plus the server you now own.

licenseAGPL-3.0

runsyour machine or their cloud

installDownload the release and run the web/CLI installer on a LAMP server; paid managed hosting is optional

dataCRM records in MySQL/MariaDB or MSSQL and attachments on the chosen server/object storage

the catch vs CapsuleSuiteCRM is a sprawling old-school CRM whose module density and administration burden are the opposite of Capsule’s compact simplicity.

setupRequires a correctly configured PHP web server and database, then ongoing backups, upgrades, and security maintenance

E

EspoCRM

open sourcewebself-hosteddocker to self-host

A traditional CRM that actually lets you change the data model; polished enough, but still your server.

licenseAGPL-3.0

runsyour server

installDocker Compose or upload the PHP package and run the web installer

dataCRM records in a self-hosted MySQL, MariaDB, or PostgreSQL database; uploaded files in server/Docker volumes

the catch vs CapsuleEspoCRM is much more complex to deploy and configure than Capsule’s polished small-business contacts, opportunities, and task flow.

setupRequires a server, database, domain/TLS setup, and ongoing upgrades/backups

F

Frappe CRM

open sourcewebself-hostedself-host, real ops

A clean leads-and-deals board with notes, tasks and email; Frappe underneath means a real server, not a toy.

licenseAGPL-3.0

runsyour machine or their cloud

installOne-click Frappe Cloud signup or the official Python easy-install deployment script on your server

dataCRM DocType records and attachments in the Frappe site database/files, on Frappe Cloud or the user's server

the catch vs CapsuleFrappe CRM needs more administration and offers less low-friction contact-management polish than Capsule.

setupFree use means self-hosting; the official production script still needs a Linux server, DNS, and command-line access

how to choose a Capsule alternative

Easiest to get running

Monica — a one-click install, no server to maintain.

Most proven

Twenty, with 54,400 GitHub stars — the largest community of the 6, which usually means more answers when something breaks.

Needs real ops to self-host

Krayin CRM, SuiteCRM and Frappe CRM are capable but expect someone to run a server, updates and backups. Budget for that before choosing one.

why people still pay for Capsule

People still pay for Capsule because CRM value compounds as the system becomes the shared memory of every customer interaction and embeds itself in the rest of the stack. The recurring cost buys deduplication, permissions, imports, sync, enrichment, email capture, automations, backups, and audit history, not just the visible interface. If none of that applies to you, any pick above saves $216 a year.
