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 BiginTwenty’s ready-made sales automation and small-business onboarding are thinner than Bigin’s out-of-the-box workflow.
setupFree use requires Docker, at least 2 GB RAM, PostgreSQL-backed containers, secrets, and domain/TLS configuration

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 BiginKrayin is less mature and less plug-and-play around everyday email, calendar, mobile, and workflow use than Bigin.
setupThe free path requires PHP/Composer plus MySQL/MariaDB, or Docker and a server; HTTPS, backups, and updates remain yours
facts verified 2026-08-10
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 BiginEspoCRM is much heavier to configure and administer than Bigin’s deliberately simple small-business pipeline.
setupRequires a server, database, domain/TLS setup, and ongoing upgrades/backups

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 BiginFrappe CRM needs considerably more configuration to reach Bigin’s ready-made pipeline and workflow experience.
setupFree use means self-hosting; the official production script still needs a Linux server, DNS, and command-line access

Personal CRM to remember everything about friends, family and contacts.

how to choose a Bigin 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 5, which usually means more answers when something breaks.
Needs real ops to self-host

what you give up by leaving Bigin
- Zoho ecosystem, telephony, forms, integrations, and mobile apps
- automatic email and calendar capture
- data enrichment
- large integration ecosystem
- enterprise reporting
None of the picks above covers all of it. The full verdict says which gaps matter.

why people still pay for Bigin
People still pay for Bigin 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 $108 a year.
