The smartest business model in software: give the community a powerful free version, sell enterprise support and features to companies. Everyone wins — individuals get world-class tools for $0, and companies get guaranteed support. Here are 30 real examples.
The full working product — you can download it, install it, use it, modify it, and even run a business on it. No trials, no time limits, no crippling restrictions. It's REAL software that works.
Everything in the community version PLUS: advanced features (SSO, LDAP, audit logs, clustering), official support (phone/email SLA), security patches first, training, and consulting. This is what big companies need and are willing to pay for.
Tudeng, idufirma, kool, mošee või väikeettevõte saab kasutada same professional software that billion-dollar companies use — completely free. And the company behind it survives because enterprises pay for support. It's the fairest business model ever invented.
Kategooriate järgi korraldatud. Igaühel neist on tasuta kogukonnaversioon.
OpenKM on täielik dokumendihaldussüsteem (DMS) — mõtle sellest kui oma privaatsest Google Drive'ist koos täiustatud funktsioonidega: OCR-tekstituvastus, dokumentide töövood, versioonihaldus, metaandmed ja täistekstiotsing miljonites dokumentides.
Alfresco on ulatuslik ettevõtte sisuhalduse (ECM) platvorm — dokumendihaldus, arhiivihaldus ja äriprotsesside juhtimine. Kogukonnaversioon on enamiku organisatsioonide jaoks piisavalt võimas.
n8n connects any app to any app with visual workflows. Trigger: "When I get an email with an attachment → save to Nextcloud → notify me on Slack → log in Google Sheets." It's a free alternative to Zapier ($20–$600/mo) ja Make.com.
