Our Rankings
Confluence
Confluence is the enterprise standard for internal IT documentation at $0-12.30/user/month based on team size. It excels with powerful search, granular permissions, deep Atlassian ecosystem integration (Jira, Opsgenie), and proven scalability for teams of 1,000+ users. The templates, macros, and version history support complex IT documentation needs. However, the interface can feel dated and there's a learning curve for new users.
- Strong integration with Excel and other tools
- Reliable platform with regular updates
- Responsive customer support
- Steeper learning curve for full feature adoption
BookStack
BookStack is ideal for budget-conscious IT teams willing to self-host. At $0 licensing cost (only infrastructure costs), it provides clean organization with books/chapters/pages structure, Markdown support, and LDAP/SAML authentication. Perfect for teams with existing hosting infrastructure and technical expertise to manage deployment. However, you'll need to handle backups, updates, and scaling yourself—no vendor support.
- Competitive pricing for the feature set
- Reliable platform with regular updates
- Responsive customer support
- May lack some advanced features of competitors
Tettra
Tettra at $5-8/user/month offers simplicity and Slack integration that appeals to IT teams who want lightweight documentation without Confluence complexity. The AI search bot answers questions directly in Slack, reducing friction. Good for teams under 50 people who prioritize ease of use over advanced features. However, limited integrations and basic editing capabilities may frustrate power users coming from Confluence.
- Strong integration with Excel and other tools
- AI-powered search and insights
- May lack some advanced features of competitors
- Steeper learning curve for full feature adoption
Hudu
Hudu at $27-29/user/month is optimized for MSPs but can work for enterprise IT teams needing asset tracking and password management alongside documentation. The modern interface and performance are strong, but the MSP-centric design and higher price make it less ideal than Confluence or BookStack for pure internal IT documentation. Best for IT teams managing complex infrastructure with password/asset needs.
- Reliable platform with regular updates
- Responsive customer support
- Good documentation and training resources
- Not as feature-rich as market leaders
- May lack some advanced features of competitors
IT Glue
IT Glue at $29-44/user/month is purpose-built for MSPs managing multiple clients, making it overkill and expensive for internal IT teams. While it offers robust features including password management and automation, the multi-client focus and premium pricing don't align with internal IT needs. Confluence or BookStack deliver better value for documenting a single organization's infrastructure.
- Competitive pricing for the feature set
- Automated workflows save time
- Not as feature-rich as market leaders
- May lack some advanced features of competitors

Frequently Asked Questions
01 What does Confluence cost for a 50-person IT team?
For 50 users, Confluence Free provides basic features at $0. The Standard plan costs $320/month ($6.40/user/month annually), adding unlimited storage, audit logs, and better support. Premium costs $615/month ($12.30/user/month annually) with 99.95% SLA, SAML SSO, and data residency. Most mid-size IT teams find Standard sufficient.
02 Is BookStack secure enough for enterprise IT documentation?
Yes, BookStack supports LDAP/SAML authentication, role-based permissions, and audit logs when self-hosted properly. Since you control the infrastructure, security depends on your deployment—use HTTPS, regular updates, and backups. Many enterprises use BookStack for internal documentation. However, you're responsible for security patches and compliance, unlike managed Confluence.
03 Can Confluence integrate with our IT tools?
Confluence integrates deeply with the Atlassian ecosystem (Jira, Opsgenie, Statuspage) and has 3,000+ marketplace apps for tools like ServiceNow, PagerDuty, Slack, and monitoring platforms. The REST API enables custom integrations. This makes it ideal for IT teams already using Jira for ticketing or wanting centralized documentation across tools.
04 How does Tettra compare to Confluence for IT teams?
Tettra is simpler and more affordable ($5-8/user/month vs $0-12.30 for Confluence) with excellent Slack integration for quick answers. However, it lacks Confluence's advanced features: no macros, limited integrations, basic permissions, and fewer formatting options. Choose Tettra if you prioritize simplicity and Slack workflows over comprehensive documentation capabilities.
05 Should internal IT teams consider MSP tools like IT Glue?
Generally no. IT Glue ($29-44/user/month) and Hudu ($27-29/user/month) are designed for MSPs managing multiple client environments. Internal IT teams don't need multi-client organization or MSP-specific integrations, making these tools unnecessarily expensive. Confluence, BookStack, or Tettra provide better value for documenting a single organization's infrastructure and procedures.
06 What hidden costs should I watch for?
Common hidden costs include setup/onboarding fees, data migration services, training and professional services, premium support plans, additional users beyond base tier, API access, storage overages, and feature add-ons.
