JetBrains GameDev Day 2026 is live today, September 28, and the agenda is unusually practical for developers who care more about shipping than conference-flavored motivational fog. JetBrains GameDev Day 2026 is free online and covers engine workflows, debugging, CI, performance, architecture and AI-assisted production across a full day of talks.

JetBrains GameDev Day 2026 has seven sessions worth flagging
The livestream began at 10:00 UTC, with the first panel examining community feedback, data and AI in game development. The event page provides the complete timetable and free online registration, so late arrivals can still jump directly to the live program. Join JetBrains GameDev Day 2026 free online.
1. TeamCity MCP and CLI with Unity
Artem Rokhin’s session uses a real Unity build pipeline to show how TeamCity MCP support and CLI tooling can bring CI status and troubleshooting closer to the IDE. The practical idea is simple: fewer browser hops just to understand why a build failed. Explore TeamCity. Join JetBrains GameDev Day 2026 free online.
2. AI-assisted Figma-to-Unity workflows
The agenda includes a session focused on moving UI work from design tooling into Unity with AI support. For teams where UI handoff becomes a repetitive translation exercise, this is the kind of workflow demo worth watching for concrete time savings rather than AI theater. Explore Unity.

3. ECS migration without rewriting the whole game
One of the strongest architecture topics tackles Entity Component System migration without assuming a team can burn the existing codebase to the ground. That makes the session relevant to production teams weighing performance gains against migration risk. Join JetBrains GameDev Day 2026 free online.
4. Mixed C# and C++ debugging from Hytale
A Hytale-focused talk explores debugging across managed and native runtimes. That is valuable territory for teams building engines, native plugins or hybrid tooling where the bug does not politely stay inside one language boundary. Join JetBrains GameDev Day 2026 free online.
5. AI-driven procedural generation with Godot
The Godot session combines C# with Gemini for procedural content generation. The useful question is not whether AI can spit out content, but how developers structure an actual repeatable pipeline around it. Explore Godot. Join JetBrains GameDev Day 2026 free online.
6. Gameplay performance and hidden tick costs
Another talk focuses on gameplay systems that quietly burn frame time through per-frame work. That is evergreen material for anyone who has opened a profiler and discovered that the “tiny” systems are collectively mugging the CPU. Join JetBrains GameDev Day 2026 free online.
7. Agentic Unreal development inside Rider
The Unreal Engine portion of the day includes agentic development using Rider. This is the session to watch if you are interested in how coding agents can operate inside a real C++ game-development environment instead of a toy repository. Explore Unreal Engine. Explore Rider.

Who should watch?
JetBrains GameDev Day 2026 is especially relevant to programmers, technical designers, tools engineers, build engineers and solo developers who already have working projects and want to remove friction from the pipeline. It is less useful if you want a beginner “how to make your first game” stream. This is mostly about the machinery behind production. Join JetBrains GameDev Day 2026 free online.
