OBA · One Base for Agents

Download OBA

An AI coding team that runs on your computer. You set up houses, give agents work, and they write, review, test and deliver code in your own project folder while you watch them on a voxel village square.

What it is and who it is for

OBA is the factory Korvenium builds with, made available to download. You create a house for a project, hire agents, and give them a task; they split it up, write the code, review and test it, and hand it back, in your own folder, on your own machine. Your chats, memory notes and projects stay on your computer; the app collects no usage data.

It is for developers, solo or on a small team, who already use a coding CLI and want several agents working on one project, and who would rather watch and steer the work than read a log.

New in 1.5.0

  • Voxel square: The Village Square now opens as a 3D village made of small cubes, on a mountain top rising out of the clouds.
  • Light follows the clock: Morning, noon, evening and night each have their own light and sky; at night torches and windows light up.
  • Houses you can open: Click a house and the camera flies to it while its walls open to show the inside; agents walk as voxel villagers.
  • Classic view and quality: The old pixel square is still in Settings → Appearance, next to a Low, Medium and High quality setting. All changes

Files and SHA-256 checksums

The file is on the release page ↗. Compare the SHA-256 of your download with the value below; the Security page shows its antivirus scan and how to check.

Installer

OBA-Setup-1.5.0.exe

Installs OBA and keeps it up to date.

SHA-256

"Windows protected your PC"

When you open the setup file you downloaded, Windows may show a blue window: "Windows protected your PC". This is not a virus warning; Windows shows it for any program that is not yet widely downloaded and has no digital signature.

OBA is made by a small independent team and does not have a code-signing certificate yet. Instead:

  • every release is scanned on VirusTotal by dozens of antivirus engines, and the results are public on our Security page;
  • the SHA-256 of the file you downloaded should match the one on that page.

To start the installer

  1. Click More info in the warning.
  2. The publisher shows as "Unknown publisher"; click the Run anyway button that appears.

You will only see this the first time.

To check the file yourself: in PowerShell, run Get-FileHash .\OBA-Setup-<version>.exe; the value must match the SHA-256 on the Security page. If it does not, do not open the file — contact us.
