Where Collabora Online and OnlyOffice differ

Across the five points below, Collabora Online has the edge on 2 points, OnlyOffice on 1 point and 2 are a tie. A count like that is a summary, not a verdict: the point that matters to you may be the one the other product wins.

Pricing model

Collabora's subscription page lists Collabora Online for Business at 3 € per user per month for up to 99 users, with Enterprise quoted for 100 users and more. OnlyOffice prices per connection: Docs Enterprise from $33 per connection per year, starting at 50 connections. A team of 20 can budget Collabora per head; OnlyOffice's 50-connection floor suits larger groups.

Edge: Collabora Online

Entry and free options

OnlyOffice's pricing page lists a Home plan at $149 per server per year for individuals, with 10 users free. Collabora's free route is the Development Edition, which the page says is for home use, testing and start-ups, with rolling updates and no long-term support. For a small permanent setup, OnlyOffice's priced Home tier is the clearer path.

Edge: OnlyOffice

Support commitments

Collabora's Business plan lists long-term support, a service level agreement, signed security updates, lifetime maintenance and a customer portal, and says its products are backed by a full-time support team. OnlyOffice's pricing page lists updates and support as a row in its plan table but gives no service level terms in the text we read.

Edge: Collabora Online

Licence and openness

Collabora Online is open source under MPL 2.0, and its site calls the codebase fully auditable. OnlyOffice lists AGPL 3.0 for its community code, while White Label branding is only sold with the paid Docs Developer plan. Both can be read and self-hosted; the licence terms differ, so a legal check matters if you embed either.

No clear winner on this point.

Company structure

Collabora Productivity Ltd is based in Cambridge, UK. OnlyOffice's own about page says Ascensio System SIA, registered in Riga, Latvia, has always held the intellectual property, and that the holding company, ONLYOFFICE Capital Group Pte. Ltd., is registered in Singapore and unites its offices. Both facts are stated by the vendor; we draw no conclusion.

No clear winner on this point.

When neither Collabora Online nor OnlyOffice fits

If neither fits: CryptPad offers end-to-end encrypted editing from France, LibreOffice is the free desktop suite behind Collabora's code, and Proton Docs is a hosted option from Switzerland.

Collabora Online vs OnlyOffice: questions

OnlyOffice's contracting entity is Ascensio System SIA in Riga, Latvia, which its about page says holds the intellectual property. The same page names ONLYOFFICE Capital Group Pte. Ltd., registered in Singapore, as the holding company that unites its global offices.

Collabora Online for Business lists 3 € per user per month for up to 99 users. OnlyOffice Docs Enterprise starts at $33 per connection per year from 50 connections, and Home is $149 per server per year. The cheaper one depends on user count.
