About
Confluence is a team wiki and knowledge management platform developed by Atlassian, founded in 2002 and headquartered in Sydney, Australia, originally launched in 2004 to give software development teams a structured, collaborative space for documentation, project planning, and institutional knowledge capture. The product was built on the premise that tribal knowledge — how systems work, why decisions were made, what processes to follow — needs to live somewhere accessible and searchable rather than in email threads, shared drives, or individual memory. Confluence became Atlassian's second major product after Jira, and the two are deeply integrated in most enterprise software organizations' toolchains.\n\nConfluence's core capabilities include pages and spaces for structured documentation, nested hierarchies for organizing knowledge by team or project, templates for recurring document types (sprint retrospectives, decision records, runbooks, meeting notes), macros for embedding dynamic content, and Jira integration for linking documentation directly to software development work. Atlassian has been investing heavily in AI capabilities through its Atlassian Intelligence platform, which brings AI-assisted page summarization, smart search, and content generation into Confluence. The product is available both as a cloud service (Confluence Cloud) and as a self-managed deployment (Data Center).\n\nConfluence is used by over 50,370 companies globally and is one of the most widely deployed enterprise knowledge management platforms in the software industry. Atlassian reported FY2024 revenue of $4.4 billion, up 23% year over year, with Confluence serving as a core component of the Atlassian product suite that 300,000+ customers use across Jira, Confluence, Trello, and other tools. Its deep Jira integration, enterprise Data Center deployment options, and AI-powered enhancements position Confluence as the default documentation platform for engineering-led organizations worldwide.
