HolyCode Cloud is a cloud AI workstation with 60+ tools already installed, built for running AI coding agents unattended.
Hand off a task, close your laptop, and the work continues. Processes, files and terminal scrollback survive the disconnect, and the machine suspends when idle and resumes in about a second, so an always-on workspace does not bill like one.
Six agent CLIs preinstalled and on PATH: Claude Code, Codex, Gemini, OpenCode, Cursor and Pi.
Plus the tooling agents actually reach for: Postgres, Playwright with its system dependencies resolved, ffmpeg, pandoc, gh, ripgrep, tmux, Node and Python with build-essential.
Bring your own key. Your Anthropic, OpenAI or Gemini key stays on your box. The provider bills you directly and there is no markup on tokens.
Most cloud dev environments are containers with an idle reaper that reclaims them when nobody has typed for a while, which is exactly what a working unattended agent looks like to a timer. Here the workspace is a real VM with a persistent disk.
Five tiers from $19 to $199 per month, differing only by CPU, RAM and disk. Every feature is on every tier. No free tier; a 7-day refund instead, with no form and no call.

HolyCode's answer:
The machine does not stop when you do. Most cloud dev environments are containers with an idle timer that reclaims them when nobody has typed for a while, which is exactly what a working unattended agent looks like to a timer. Here the workspace is a real VM with a persistent disk. Hand an agent a four-hour task, close your laptop, and the processes, files and terminal scrollback are still there when you come back. It suspends when idle and resumes in about a second, so always-on does not mean always-billing.
HolyCode's answer:
Three practical differences. First, nothing gets reclaimed for idleness, so long unattended agent runs actually finish. Second, every tier includes the full toolset. Tiers differ only by CPU, RAM and disk, so paying more buys horsepower rather than unlocking features. Third, you bring your own Anthropic, OpenAI or Gemini key and the provider bills you directly, with no markup on tokens.
Where it is not the right choice: if you want a free tier to try, there isn't one, because every account is a real VM that costs money from the first minute. There is a 7-day refund instead.
HolyCode's answer:
Developers running AI coding agents on real work rather than demos. Typically people who already pay for Claude, Codex or Gemini and have hit the point where the bottleneck is not the model but the machine underneath it. Many have tried tmux on a VPS and got tired of maintaining the VPS.
HolyCode's answer:
It started as an open-source Docker image for running coding agents with persistent state, which is still free and maintained at github.com/CoderLuii/HolyCode. The most common feedback was that persistence mattered most: sessions, settings and progress surviving a rebuild rather than starting over each time. The hosted version is that same image on a machine someone else maintains.
HolyCode's answer:
Fly.io machines with persistent volumes for the workspaces, Docker and Debian for the image, ttyd for the browser terminal, Node and React for the interface, and Cloudflare for the site and control plane.
