Share Your Work and Attend the 2026 Cesium Developer Conference
The 2026 Cesium Developer Conference is now open for presentation proposals and registration! If you’re innovating in open geospatial frontiers, now is the time to submit your proposal and be part of the conversation that’s accelerating real-world impact, June 8-10 in Philadelphia.
2025 Cesium Developer Conference
Community-powered insights and open innovation
What set Cesium DevCon 2025 apart was its community-driven spirit. The inaugural DevCon brought together hundreds of developers, creators, and innovators to share, learn, and connect around the future of open 3D geospatial technology.
With 87 of the 101 speakers drawn from the ecosystem, the event showcased real workflows and solutions from the people building and using 3D geospatial technologies every day. Sessions spanned six tracks: 3D, AI, and Data Technology; AEC and Digital Twins; Aerospace and Defense; Cesium, iTwin, and 3D Tiles; Climate and Disaster Resilience; and Market and Education.
From breakthrough case studies like Buendea’s digital twin of the Moon for NASA’s XR Operations Support System (XOSS) to MapStore’s integration of CesiumJS to MapStore’s integration of CesiumJS, there was something for everyone.
Already, submissions are arriving to highlight compelling areas of the ecosystem, including 3D micro-experiences, AEC and BIM, astrodynamics, Cesium for Unity, sensor integration, and more.
Why you should talk and attend: engage, learn, and celebrate with the community
Presenting and attending come with great benefits. And this year, we’re adding new features.
For speakers:
- Complimentary conference registration for primary authors of accepted talks (with discounted co-presenter tickets available).
- A platform to engage with hundreds of developers, engineers, and decision-makers.
- Inclusion in the full recorded library as a lasting showcase of your work.
For all attendees:
- Networking at community tables, meals, and receptions with peers and leaders in the ecosystem, including parties and both welcome and closing receptions perfect for community building and celebration.
- Lightning talk slots: Share and learn from quick insights or demos.
Pre-conference and limited events:
- Pre-conference workshop day, now with expanded capacity: hands-on deep dives into CesiumJS, Cesium ion, and open-source plugins for Unity, Unreal Engine, and NVIDIA Omniverse.
- The Developer Cove: a dedicated space to meet directly with Cesium experts to discuss projects, new features, or any deep-dive topics.
- Early Career Event: Following strong participation from academic and early-career attendees last year, we’re creating a dedicated opportunity for networking and engaging with the Cesium technical team.
Flashback
The 2025 Cesium Developer Conference saw real-world implementations and new connections. As Patrick Cozzi said in his reflections on the session recordings, it was “a celebration of the accomplishments of the 3D geospatial community,” as hundreds of developers converged to share and learn.
