Disc Image Studio is an open-source tool, published on GitHub by the account JiaFeiMiao-K-Cat, that lets you use any burner to etch an image you can see with the naked eye onto a CD, a DVD or a single-layer Blu-ray disc. It converts a picture into data that fits each format's physical-layer limits; when that data is written, the pattern of burned areas forms the image on the disc surface. No special label discs are needed.
What it supports: any CD (exported as WAV with CUE, or RAW audio), any DVD (exported as an ISO image) and single-layer 25 GB BD-R discs only. CD and DVD images use black-and-white two-level dithering. Design tools include layers, dithering, gamma and brightness controls, presets for several disc brands and a calibration workflow that measures your disc's geometry. You can export the image and burn it with other software, or burn directly from the app.
Traction: the repository was created on 23 August 2026, but nearly all of its stars came in the past week: RepoRank counted 8,404 stars on 8 November, +8,322 in seven days (the GitHub page showed about 8,500 stars and 312 forks). A Hacker News post on 3 November reached 363 points and 79 comments.
How to try it: download the win-x64.exe (or native win-arm64.exe) build from the project's GitHub Releases; it runs directly on Windows 10 version 2004 or later and Windows 11, with the .NET runtime bundled. Linux and macOS get only an experimental command-line build. Building from source needs the .NET 10 SDK. The README says the app does not connect to the internet, upload files or collect telemetry. Licence: GPL-3.0-or-later.
Limits: direct burning is experimental, and the README says to use only blank test discs you can afford to lose; an interrupted burn, power loss or slow data generation can ruin a disc. Dual-layer Blu-ray is not supported, an interrupted BD-R usually cannot be resumed, ARM64 has not been verified for real burning, and the result depends on the disc, drive, firmware and write strategy.
