At the Open Source Initiative (OSI), we track a wide range of Open Source conferences, including events that intersect with AI, cloud, cybersecurity, and policy. Around the world, conferences bring together maintainers, developers, contributors, policymakers, researchers, legal experts, and organizations working on shared digital infrastructure.
Below is a chronological overview of the top 50+ Open Source conferences of 2026 we are tracking, with links and short descriptions. These events are not specific to any single programming language or framework. Instead, they reflect the broader Open Source ecosystem and the communities that sustain it.
