Here’s a visual snapshot of everything that went down last month in Bengaluru at Open Source India — the flagship gathering for the open source community that includes industry leaders, developers, hackers, innovators, as well as tech giants and start-up organisations.
November 2025 marked the 22nd edition of Open Source India (OSI) — one of the most anticipated events for anyone passionate about open source tech. Born as LinuxAsia back in 2004, OSI has spent more than two decades bringing together the open source community, industry leaders, and tech trailblazers with one mission: to accelerate how open source is built, adopted, and scaled in India and beyond.
This year, developers and open source enthusiasts from across India and neighbouring regions packed into the NIMHANS Convention Center on November 5–6, 2025. The event delivered 85+ expert-led sessions, spread across six conference tracks and ten hands-on workshops — all running in parallel over two days. From cutting-edge frameworks to real-world deployments, OSI 2025 was a powerhouse of learning, collaboration, and open source energy.
There were multiple hands-on workshops on AI and open source related topics including ‘Beyond the API: Hands-On Command-Line Mastery of Gemini’ by the Google Cloud team on the first day of the event. On Day 2, another team from Google Cloud conducted a houseful workshop on ‘Deploy, Manage, and Observe ADK Agent on Cloud Run’. The workshop on ‘Building Agentic Application with Anthropic in Snowflake’ conducted by Kamesh Sampath, lead developer advocate at Snowflake, attracted a lot of attendees on both days.
The workshops on ‘Hands-On Cassandra: From Data Modeling to Full Deployment’ and ‘Building Production-Ready Knowledge Graphs: Hands-On Workshop with Neo4j, Graph RAG, and LangChain’ were also well-attended.
The keynote sessions in the conferences were delivered by experts from Google Cloud and Neo4j. Day 2 witnessed a keynote by Percona, which was followed by a session by Sarath Chandra K., Chief of Digital and Technology, NPCI Bharat Billpay Ltd. The afternoon keynote was delivered by Jim Grisanzio, Host, Duke’s Corner Java Podcast, Oracle, who shared his thoughts on ‘Building FOSS Communities’.
The community also enjoyed the panel discussion on ‘Open Source in the Age of Generative AI: Collaboration, Compliance, and Control’. Apart from the talks by experts, the event was also an occasion for exhibitors to showcase their various community-centric offerings to thousands of attendees.
The audience at this mega 22nd edition of OSI ranged from developers and tech heads to evangelists and academicians (see graph below).
