100 Alternatives to Microsoft 365 for Solo Founders and Small Teams
Microsoft 365 combines several jobs that a small company may prefer to buy, host, or manage separately: email, calendars, files, office documents, chat, video meetings, and project coordination. That makes an “alternative” less a single product category than a set of choices. Some options below aim to replace much of the suite, while others are stronger substitutes for one particular Microsoft 365 application.
For a solo founder, the practical question is usually which workflows need to remain connected and which can stand alone. A team with heavy spreadsheet use may prioritize office-file compatibility. A privacy-conscious business may focus first on email and storage. A distributed team may put meetings, chat, and task visibility ahead of a single suite dashboard. The 100 products below are grouped accordingly rather than ranked.
Suite and collaboration platforms
These services and platforms can cover multiple workplace functions, though their mix of hosted, self-managed, and modular offerings differs considerably.
- Google Workspace
- Zoho Workplace
- ONLYOFFICE Workspace
- Nextcloud Hub
- Infomaniak kSuite
- IceWarp
- Open-Xchange
- Kopano
- Collabora Online
- CryptPad
Desktop office suites
Desktop suites can be a sensible fit where local files, offline work, or familiar document-oriented workflows matter more than a tightly integrated cloud workspace.
- LibreOffice
- Apache OpenOffice
- SoftMaker Office
- FreeOffice
- WPS Office
- OfficeSuite
- Calligra Suite
- Apple iWork
- Hancom Office
- Polaris Office
Document and knowledge-work tools
These products are useful when the main need is shared writing, living documentation, internal wikis, or a workspace for decisions and operating knowledge.
- Google Docs
- Dropbox Paper
- Notion
- Coda
- Quip
- Nuclino
- Slite
- Craft
- Outline
- Etherpad
Spreadsheet and structured-data tools
Microsoft Excel is often the hardest component to replace because it can serve as a calculator, lightweight database, planning tool, and reporting layer. These options span those roles.
- Google Sheets
- Zoho Sheet
- Airtable
- Smartsheet
- Rows
- SeaTable
- Baserow
- NocoDB
- Grist
- EtherCalc
Presentation tools
Presentation alternatives vary from conventional slide editors to design-led tools built around templates, visual storytelling, or web-based sharing.
- Google Slides
- Keynote
- Canva
- Prezi
- Pitch
- Beautiful.ai
- Gamma
- Zoho Show
- LibreOffice Impress
- ONLYOFFICE Presentation Editor
Email and calendar alternatives
Email and scheduling deserve separate scrutiny during a Microsoft 365 change. Domain setup, aliases, shared mailboxes, calendar sharing, and mobile access can matter as much as the inbox itself.
- Fastmail
- Proton Mail
- Zoho Mail
- Mailbox.org
- Tuta Mail
- Posteo
- Migadu
- Runbox
- Teamup
- Cal.com
Cloud storage and file-sharing services
For files, the important distinctions are usually sync behavior, external sharing controls, storage location preferences, version history, and whether the service connects cleanly to the team’s document editor.
- Google Drive
- Dropbox
- Box
- pCloud
- Sync.com
- Tresorit
- MEGA
- Proton Drive
- Seafile
- ownCloud
Team chat tools
Teams is both a chat product and a meeting surface. Organizations replacing it sometimes choose a focused messaging tool and pair it with a separate video service.
- Slack
- Mattermost
- Rocket.Chat
- Zulip
- Twist
- Flock
- Chanty
- Element
- Google Chat
- Discord
Video meeting platforms
Meeting software should be assessed against the realities of a company’s calls: client access, recording needs, recurring internal sessions, browser support, and integrations with calendars.
- Zoom Workplace
- Google Meet
- Jitsi Meet
- Whereby
- BigBlueButton
- Cisco Webex
- Zoho Meeting
- Nextcloud Talk
- GoTo Meeting
- RingCentral Video
Project and work-management tools
Microsoft 365 users often rely on a combination of Planner, Lists, To Do, and spreadsheets. Dedicated work-management products can provide a clearer replacement for that collection of responsibilities.
- Asana
- Trello
- ClickUp
- Basecamp
- Linear
- monday.com
- Jira
- OpenProject
- Plane
- Taiga
How to compare a realistic replacement stack
A useful comparison begins with work rather than feature checklists. Identify the documents that must open reliably, the mailboxes and domains that must move, the people who need outside file access, and the meetings that involve clients or contractors. Those requirements narrow a list quickly.
Replacing Microsoft 365 does not always mean finding one new vendor. For many small teams, a deliberate combination of specialized tools is the more workable alternative.
Migration risk also varies by component. Moving files may be straightforward, while transferring shared calendars, permissions, archived email, or complex spreadsheet models can require more planning. Compatibility tests are particularly relevant for documents that use advanced formatting, macros, or linked data. A smaller, simpler stack can reduce administrative overhead, but a fragmented one can create new handoff problems. The best fit is therefore the option, or combination of options, that supports the team’s actual operating habits without adding unnecessary complexity.
