The most frustrating part of trying someone else’s repository is often the setup loop: run a command, hit a missing-tool error, search for a fix, then discover the next mismatch.
I built Reporun to show that list before you start installing things. Paste a public GitHub or GitLab URL and the desktop app reads the repo’s manifest files, checks your local runtimes and tools, and reports what is compatible, missing, or the wrong version. It pins the check to a specific commit so the report and eventual download refer to the same code.
For example, a project might need Python >=3.10 and <3.13, pnpm, and Docker. If your machine has Python 3.13 but no pnpm, Reporun surfaces both issues together and shows the relevant files and proposed fix commands. Nothing installs or runs until you review and approve the exact command.
The current preview covers JavaScript/TypeScript, Python, Rust, Go, Java, Ruby, PHP, .NET, Docker, and common environment-template files. It’s free and open source. There’s a sample report on the site if you want to see what the result looks like before downloading.
A few honest limits: it checks declared requirements, not undocumented secrets or external services. It supports public GitHub/GitLab repos, not private ones. Approving a command can still run the project’s own code—Reporun is a setup guide, not a sandbox. The Mac installers are signed and notarized; the Windows preview is currently unsigned.

I’d especially value feedback from anyone who has recently onboarded to an unfamiliar repo: what setup failure did the README miss?
