Choosing well
Compare free and paid plans
A free plan is available from tools in this category, and open-source projects provide another route without a subscription. Check what the free option includes before committing.
Paid starting prices vary. Archbee lists $80 per month with a 14-day trial, ClickHelp lists $194 per month with a 14-day trial, HelpNDoc lists paid plans from €99, and HelpSmith lists plans from $199 per user.
Choose where documentation runs
Platform choices include hosted web services, self-hosted software and desktop tools for Windows, macOS or Linux. An API option can matter when documentation needs to connect with another system.
Confirm the hosting model and supported operating system before you plan a publishing workflow.
Match your writing workflow
Markdown support can suit teams that keep documentation in text files, while included editors may be better for visual authoring. Version control is useful when you need tracked changes and coordinated updates.
Check these capabilities against how your team writes and reviews documentation.
Check publishing and access controls
A custom domain can keep published documentation under your own web address. API reference tools help when developer documentation needs structured endpoint information.
Single sign-on can simplify account access for an organisation. Verify that the plan you choose includes the controls you need.
Read the licence terms
Open-source availability and a free plan are different things. Review the licence, hosting requirements and permitted use before adopting a tool for a project.
This is especially important when you need to read or change the code or run the platform yourself.
