What's New in InfraSim

1.0.6

September 30, 2026

Easier to start, easier to learn: - Chapter 1 now teaches one idea per level, with three new levels: Fast Enough, On a Budget and Where the Data Lives. - Before each level, every goal is explained in plain words, and new components get a card saying what they do. - During a run you only see the numbers the level grades. - A new glossary, "Words you'll see", explains every term in plain English. - After a run, the advice only suggests things you can use on that level. - Fixed: the tutorial no longer asks you to apply changes right after your first deploy.

Genuinely amazing idea

Please add some music, so I can stay more focused

Response from developer

Thank you, this made our day! Music is a great call. Right now InfraSim only has sound effects, so we're adding a calm, focus-friendly soundtrack you can turn on in Settings. If a particular style helps you concentrate (lo-fi, ambient, synth), let us know through Support in the app. Thanks for playing, and for the five stars! : )

Makes system design click

Super easy to pick up and surprisingly addictive. I like that you learn by actually building instead of just reading about concepts.

Response from developer

Thank you, that's exactly the idea: you learn it by building it and watching it break. Glad it's addictive in the good way! More chapters are on the way. Thanks for playing! : )

Actually makes system design fun

Really fun way to learn and experiment with system design!! I love being able to build an architecture and then actually see how it handles traffic and failures instead of just reading about it! The random events make you think about scalability and tradeoffs, and the sandbox is great for trying different ideas! Love it and can’t wait to see more!

Response from developer

Thank you! Watching a design handle traffic and failures is exactly what we wanted InfraSim to feel like, so it's great to hear that comes through. There's a lot more since the version you played: 47 levels across 10 chapters and a gentler start, and the next update makes winning feel a lot more satisfying. Glad the sandbox is earning its keep too. Thanks for playing!
