Microsoft 365 vs ONLYOFFICE
Is it time to switch? We break down the differences so you can stop bleeding money.
Choose ONLYOFFICE.
If you want to own your data, save money, and avoid vendor lock-in, ONLYOFFICE is open source and community-driven.
What Actually Matters
No fluff — just the differences that affect your decision
ONLYOFFICE is open source (AGPL-3.0). Microsoft 365 is closed. If vendor lock-in keeps you up at night, this is the deciding factor.
ONLYOFFICE supports self-hosting via Docker. Microsoft 365 is SaaS-only — convenient, but you're renting, not owning.
ONLYOFFICE has the bigger crowd: 7.0k stars vs 0. More contributors, more integrations, more momentum.
ONLYOFFICE is built in Shell — you can read the source, contribute, or fork it. Microsoft 365 is closed-source, so you're trusting their engineering.
Try both — most offer free tiers. The right pick depends on your stack size, team, and tolerance for DevOps.
