What you are probably seeing

Your invoice shows a recurring subscription fee for Microsoft 365 that has not changed in years despite your team size staying the same. You notice that each user account adds up quickly when compared to free hosting alternatives that charge nothing for basic access.

You open your workflow and realize that certain integrations rely on Microsoft-specific features that do not exist in open source versions, creating a gap between what you need and what is available for free.

Why it happens

Microsoft 365 is designed as an ecosystem where email, documents, and chat are tightly linked, making it hard to swap just one piece without breaking the others. Open source tools often stand alone, so migrating means finding a glue layer or accepting a less seamless experience.

Many open source replacements are powerful but require self-hosting or technical setup, which feels risky compared to the managed service you already have. This hesitation keeps teams stuck on the paid option even when a free path exists.

What changed recently

Step by step

1. List every Microsoft 365 feature your business actually uses and rank them by daily importance. Search openaltfinder.com for an open source match for each item on that list. Identify the one app that has no suitable open source replacement. Assign a specific team member to test the top two open source candidates for that missing app this week. Document which open source tools can be hosted on your existing infrastructure without extra fees.
