Bigin alternatives: 8 free & open-source picks
Curated, verified, and actually free. No trials, no crippled tiers. Star counts and last-activity dates checked by hand, not scraped and forgotten.
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

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

A real two-seat CRM for free; 1,000 contacts is where the upsell starts counting.
licenseproprietary, free
runstheir cloud
installHosted signup; optionally connect/import email, calendar, and contacts
dataStructured CRM customer records stored and processed on HubSpot's cloud servers, with regional hosting options and exports
setup✓ installs clean
the catch vs BiginHubSpot’s free tier puts much of the useful workflow automation behind paid hubs and surrounds the simple pipeline with a larger upsell-heavy suite.

A full hosted pipeline for unlimited users, provided CRM is the only Odoo app you marry.
licenseproprietary, free
runstheir cloud
installHosted Odoo Online signup with CRM selected as the single free app
dataStructured Odoo records in an Odoo-hosted customer database; records can be exported from list views

licenseproprietary, free
runstheir cloud
installHosted Zoho account signup
dataStructured CRM service data stored on Zoho's cloud servers; Zoho states users can access, export, and delete service data

licenseproprietary, free
runstheir cloud

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.
Is there a free alternative to Bigin?
Yes: Twenty, Krayin CRM, EspoCRM and 5 more. Every tool on this page is either open source or genuinely free to use long-term: no trials, no crippled tiers.
Should I just build my own Bigin?
Our verdict is KINDA. The core loop is buildable, but a dependable replacement becomes a real weekend or multi-day project. For Bigin, run a small-business pipeline with contacts, activities, and simple workflows. The hard boundary is zoho ecosystem, telephony, forms, integrations, and mobile apps, plus integrations, data quality, and workflow lock-in. If you'd rather build, the exact one-shot prompt is free at vibecodeit.com/bigin.
