Atlassian makes Jira, Confluence, Bitbucket, Trello, and other tools used by software teams around the world. Jira handles issue tracking and agile planning. Confluence is a wiki for documentation and knowledge sharing. Bitbucket provides Git hosting with built-in CI/CD. Together they form a connected suite where tickets link to code and documentation.

Many enterprise development workflows are built on Atlassian products, for better or worse. The tools are powerful but can become complex at scale. Smaller teams often use Trello, which is simpler and free for basic use. If you work in a company that already uses Atlassian, learning the ecosystem is usually unavoidable and often genuinely useful.
