OBS Studio 33.0.0 released with official builds and checksums for Windows, macOS and Ubuntu 26.04

OBS Studio 33.0.0 is out

The OBS Project has published version 33.0.0 of OBS Studio, the widely used open-source application for recording and live streaming. According to the release page on GitHub, which reached the front page of Hacker News on 24 October 2026, the new major version ships with a full matrix of official builds for Windows, macOS and Linux, and every artifact is paired with a 64-character hexadecimal checksum in the SHA-256 format.

In total, twelve artifacts are listed: installers and portable archives for end users, a Linux package, a source tarball, and several debug-symbol bundles for developers and crash analysis.

What you can download

On Windows, the release provides a standard x64 installer and a portable x64 ZIP archive, plus an ARM64 build distributed as a ZIP, with no ARM64 installer among the listed artifacts. Debug symbol archives in the Windows PDB format are published separately for both architectures.

On macOS, OBS continues its two-track approach: separate disk images for Intel machines and for Apple Silicon hardware, each accompanied by a matching dSYM archive containing debug symbols.

For Linux, the official package targets Ubuntu 26.04 on x86_64. It is distributed as a standard .deb package, along with a separate .ddeb file that carries the debug symbols in Debian packaging form. A source tarball, OBS-Studio-33.0.0-Sources.tar.gz, completes the set for anyone building from source or repackaging for other distributions.

The portion of the release notes that surfaced with the story covers the download matrix and checksums rather than a changelog, so anyone wanting the full list of changes in version 33 should consult the release notes on the project's GitHub page directly.

Verifying a download

The checksums let users confirm that the file they downloaded is byte-for-byte identical to what the project published, which protects against corrupted transfers and against tampered copies circulating on mirrors or third-party download sites.

Verifying is a one-line operation on each platform. On Linux, run sha256sum followed by the file name. On macOS, use shasum -a 256. On Windows, certutil -hashfile with the SHA256 algorithm produces the same digest. If the resulting value matches the one listed on the release page, the download is intact.

Debug symbols alongside release builds

The PDB, dSYM and ddeb files are not needed for everyday use, but they matter for troubleshooting. They allow debuggers and crash-reporting tools to translate raw stack traces into function names, source files and line numbers. By publishing them for every platform variant, the project makes it possible for contributors to diagnose crashes reported against the official release builds rather than only against custom compiles.

Why it matters

OBS Studio is the default choice for a huge share of streamers, podcasters and anyone producing screen recordings, and a jump in the major version number affects that entire user base. Several details in this release stand out beyond the version bump itself.

First, publishing checksums for every artifact, including the source tarball, is good supply-chain hygiene for software that users frequently download from sources other than the project's own pages. Second, the continued availability of native Windows ARM64 and Apple Silicon builds shows the project tracking the shift away from x86-only hardware. Third, targeting Ubuntu 26.04 rather than an older LTS release keeps the official Linux package aligned with current distributions, even if it means users on older Ubuntu versions must rely on community packages or build from the provided sources. The attention the release drew on Hacker News underlines how closely the streaming and open-source communities watch each major OBS release.
