Confluence vs Stack Internal

Confluence

• Teams that run Jira and want documentation linked to their issues
• Company wikis and intranets organized into spaces per team or project
• Small teams: the Free plan covers up to 10 users

Stack Internal

• Engineering organizations grounding AI agents in their own verified knowledge
• Teams whose answers get buried in Slack or Microsoft Teams threads
• Groups of up to three people trying it on the free Starter plan

Confluence

• The Free plan stops at 10 users and 2 GB of storage and has no space or page permission settings.
• The pricing page's default prices ($5.42 Standard, $10.44 Premium) are per-user averages for a 300-user team; the first 100 users cost $6.70 or $13.20 each.
• Enforced SSO and SCIM need a separate Atlassian Guard Standard subscription on every plan except Enterprise, which is sold on annual contracts only.
• The self-managed Data Center edition reaches end of life on March 28, 2029, when its subscriptions expire and it becomes read-only.

Stack Internal

• Usage is metered in Flow Credits: a search or answer uses 1 credit and an update uses 3. Credits reset each usage period and unused ones do not roll over.
• The free Starter plan allows 3 collaborators and 1,000 credits a month, and leaves out SSO, audit logs and health and usage insights.
• The Organization plan has no published price: it is quoted by sales according to the number of credits needed.
• Connecting a Stack Overflow enterprise Q&A instance requires a Stack Internal Community Enterprise plan.

Confluence

Pages and spaces

Pages hold project plans, meeting notes and policies, and are grouped into spaces with a page tree. Several people can edit at once, with inline and page comments and version history.

Whiteboards

Freeform canvases for brainstorming and diagrams, with built-in links to Jira. Free allows 3 active whiteboards per user, Standard 10, and Premium and Enterprise have no limit.

Databases

Structured collections that gather information from Jira and other apps and can be laid out as tables, cards or boards.

Rovo AI

Rovo Search, Chat and Agents come with paid plans and are metered in monthly credits: 25 per user on Standard, 70 on Premium and 150 on Enterprise.

Automation

Rule-based automation with templates and a low-code builder. Monthly allowances run from 50 steps per subscription on Free to 500 steps per user on Enterprise.

Permissions and external sharing

Paid plans add space and page permissions, view-only public links, anonymous access and up to 5 free guests per paid user, each limited to a single space.

Stack Internal

Automatic capture

Connectors for Slack, Microsoft Teams, Google Docs and Stack Internal Community, plus a custom ingestion API, pull content in and break it into reusable units of knowledge.

Trust engine and confidence labels

Answers carry reviewer, recency and corroboration labels, and conflicting information is flagged, so a reader can tell when knowledge is reliable or needs validating.

Expert validation

Subject-matter experts are detected automatically and can also be managed by hand. Critical gaps trigger a validation workflow routed to them through Slack.

Scopes and permissions

Knowledge is organized into role-based Scopes so that people, teams and AI agents reach only what they should. Custom roles come with the Organization plan.

Delivery to people and AI agents

A chat interface, a REST API and an MCP server bring validated knowledge to people and to assistants and coding agents such as Claude and Cursor.

Q&A, Articles and Collections

The Community features keep Stack Overflow-style Q&A, long-form Articles, custom tags and curated Collections of related content.
