Self-Host

Self-host your own online developer toolkit

Run MyDevTools on infrastructure you control when you want a private developer tools hub for personal use, internal teams, labs, or security-sensitive workflows.

When self-hosting makes sense

Self-hosting is best when your team has internal workflows, strict data policies, or a preference for owning infrastructure.

  • Keep the web app and backend inside your chosen environment.
  • Control deployment, access, logs, data storage, and network boundaries.
  • Avoid relying on a public hosted utility site for sensitive developer work.

What you get

Self-hosted MyDevTools uses the same product surface: tool directory, dashboard, secure workflows, and developer utilities.

  • Access the full GPL-3.0 codebase.
  • Use all included tools without a license fee from MyDevTools.
  • Customize deployment and operations for your own environment.

When cloud is better

Managed cloud is better when you want the product without owning deployment and maintenance.

  • Use cloud for quick personal access and hosted sync.
  • Use self-hosting for private infrastructure or compliance needs.
  • Both options keep the same platform story instead of separate products.
