Best IT Documentation Software in 2026

Keeping IT knowledge organized can involve documenting assets, mapping infrastructure and capturing operational procedures. Compared on asset inventory, network discovery and runbook templates, these entries also specify API access, deployment choices and SSO support. Documented asset limits indicate the scope each option lists; free-plan availability and paid-from pricing add commercial details. CompassDocs, Rundeck and Danbyte are among the software names here. Consider what your team needs to document and discover, then compare the listed access, integration and runbook details to see which options describe capabilities relevant to your work.
