Download FlowLatch and check the build before you run it
This is the official download page for FlowLatch. The button gives the original build as the setup program, about 34 MB, for Windows 10 and 11. Compare its SHA-256 checksum with the published manifest before you run it, because the installer is not code-signed yet.
- Press the download button to get the setup program of about 34 MB.
- Compare the SHA-256 checksum of the file with the published manifest, using the certutil command shown below. The command is part of Windows, so there is nothing extra to install.
- Run the setup. If Windows SmartScreen warns, choose More info, then Run anyway, only after the checksum matches. The warning appears because the installer is not code-signed yet.
- Open the app, connect a model, and choose the project folder you want the agent to work in. Start with a small folder that holds a few tests of your own.
No account is needed to run the app. A cloud AI provider may charge you separately for its own use, and that is between you and the provider. When you press the download button, this website records the time, your IP address, your browser's user agent and the referral source, if any, to count downloads, and then sends you to the installer. The privacy page lists everything this website records. For your first run, choose Ask first, pick a folder you own, and ask for one small task, such as listing the test files and running your test command once.
System requirements
FlowLatch runs on Windows 10 and 11 on x64 PCs. The interface is available in 13 languages, and no account is needed to run it. You also need a model to talk to: a cloud AI provider through an API endpoint, a model running locally on your PC, or the built-in model, which is ready to use without your own endpoint. Disk space and memory depend on the model you use: a local model needs more of both than a cloud endpoint, which needs a network connection instead. Shell commands run in local Windows, in WSL or over SSH on a server you own, so choose the environment that matches your project. File tools work in the chat's working folder, while Shell, web and SSH are not limited to it, so keep the work to systems you are authorised to use. A portable single executable of about 25 MB also exists, but the button on this page gives the setup program.
How updates work
New versions are published automatically, and the installer build enables auto-updates. When a newer version is ready, the app shows an Update button. Version 2.9.30 was released on 8 Nov 2026. You do not need to come back to this page for every release, but you can compare the checksum of any new download with the published manifest in the same way. Update checks use the network, like web search and the phone-browser control, and the privacy page describes each of these optional features.
Verify the checksum
certutil -hashfile "C:\Users\you\Downloads\<downloaded file>.exe" SHA256Run the command in a Windows terminal, replace the path with the file you downloaded, and compare the result with the SHA-256 value in the published manifest. If the two values differ, do not run the file. Because the installer is not code-signed yet, SmartScreen may show a warning even for a genuine build, so use More info and Run anyway only after the checksum matches. A checksum is a short fingerprint of a file, and two files with the same content always give the same fingerprint, which is why a match tells you the download is complete and unchanged.
