Hero Agent
Hero Code — the autonomous AI software engineering agent. Describe a project in plain English and watch it build.
v0.8.0 browser · live desktop · built, not published
Windows installer built locally (0.8.0) — not published yet; browser version is live now.
There are no public desktop binaries on this page today. The browser version at agent.herostudios.dev is the way to use Hero Code right now — no install, no download.
Want the desktop build? Its status is tracked right below on this page — publishing installers is the next milestone on the roadmap.
Desktop build status
Where the 0.8.0 desktop build stands
Straight from the release registry: built-not-published — Windows installer built locally (0.8.0) — not published yet; browser version is live now.
| Platform | Artifact | State | Get it today |
|---|---|---|---|
| Windows | HeroCode-Setup-0.8.0.exe | built locally · not published | Use the browser app |
| macOS | HeroCode-0.8.0.dmg | planned | Use the browser app |
| Linux | HeroCode-0.8.0.AppImage + hero-code_0.8.0_amd64.deb | planned | Use the browser app |
Why nothing downloads here. The Windows installer for 0.8.0 exists
on the maintainer's machine but has not been published — we do not link files we have not
shipped. The browser app carries every 0.8.0 feature today; publishing installers
is next on the roadmap. System requirements when it
ships: Windows 10 (64-bit) or later · macOS 11 Big Sur or later (Intel / Apple Silicon) · Ubuntu 20.04+ / Fedora 36+ (glibc 2.31+) — 4 GB RAM minimum, 8 GB recommended.
