CheckcraftPostman download for Windows, Linux and Mac: what to do if it will not download
Download Postman from its official site, not from software catalogs. Here is where, which builds exist, when you need an account and what to check if the download fails.
Where to download it officially
The official download page is postman.com/downloads. For Windows, Postman publishes an .exe installer for 64-bit Intel and ARM processors; for macOS, builds for Intel and Apple silicon; for Linux, a Snap package and an archive for x64 and ARM64. Postman recommends Snap on Linux because the package already includes the libraries it needs. The archive is unpacked with tar and Postman is started from the unpacked folder.
# Linux with Snap
sudo snap install postman
# Linux from the archive
tar zxf <downloaded archive>.tar.gzDo you need an account
The desktop app can send requests without signing in; Postman calls this the lightweight API Client. Cloud collections, workspaces and collaboration need an account, and the web version in the browser only works with one. Since March 2026 the Postman Free plan is for a single user; collaboration needs a paid plan.
Is there a portable version
There is no portable build on the Postman download page. Builds without an installer found on GitHub and in software catalogs come from third parties. Before running one, find out who built it and where it gets its files. If your company policy forbids installing software, talk to your administrator instead of looking for a workaround.
If it will not download or install
First open postman.com in a browser. If the site does not open from your office network, a proxy or company filter may block the download. If the file downloaded but will not install, check the architecture: official builds are 64-bit only. Antivirus software or company policy may prevent installing programs, and then you need an administrator. If Postman is installed but does not work, see the separate troubleshooting guide.
If you need an app without an account or cloud
If you need Postman to check API responses rather than to collaborate in the cloud, look at Checkcraft. It is a desktop app for Windows and Linux: it downloads without sign-up, keeps checks on your computer and defines them as rules without JavaScript. Postman collections and cURL commands can be imported. Checkcraft is not a copy of Postman and does not replace its cloud or shared workspaces, but it can check related records in Kibana logs.
Repeat this on your own API
Checkcraft is a desktop app that saves API response checks without code and shows what did not match. Start with a sample, then use your own sanitized data. Free runs on Windows and Linux with no time limit.
