Features and specs

What each product offers, as listed by its team.

StackBlitz 6 features
HolyCode 0 features
  • Speed
    StackBlitz is known for its quick load times and fast editing capabilities, making it ideal for rapid development and testing.
  • Ease of Use
    The interface is intuitive and user-friendly, allowing developers to get started quickly without a steep learning curve.
  • Zero-Setup
    Users can write, compile, and run code directly in the browser without any setup or configuration required.
  • Integrations
    StackBlitz integrates seamlessly with GitHub, allowing for easy import and export of repositories.
  • WebContainers
    StackBlitz uses WebContainers to run Node.js applications in the browser, providing a near-native development experience.
  • Collaboration
    Real-time collaboration features allow multiple users to work on the same project simultaneously, similar to Google Docs.

Possible disadvantages

  • Limited Plugins
    Unlike traditional IDEs like VSCode or IntelliJ, StackBlitz has a limited ecosystem of plugins and extensions.
  • Online Dependency
    StackBlitz requires an internet connection to function, which can be a limitation for developers who need to work offline.
  • Performance
    For very large projects or those requiring extensive computational resources, performance may degrade compared to local development environments.
  • Mobile Accessibility
    While StackBlitz is accessible on mobile devices, the user experience is not as optimized as it is on desktop browsers.
  • Limited Framework Support
    Although StackBlitz supports many popular frameworks, it doesn't support all frameworks or versions, which could be limiting for some projects.
  • Storage and Persistence
    Files and data are stored in the cloud, which might raise concerns around data privacy and persistence for some users.

Questions & Answers

As answered by people managing StackBlitz and HolyCode.

What makes your product unique?

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.

Why should a person choose your product over its competitors?

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.

How would you describe the primary audience of your product?

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.

What's the story behind your product?

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.

Which are the primary technologies used for building your product?

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.
