stackline

Software for
independent work.

Stackline is a software studio for individuals and small teams. Our first product brings AI-assisted development into a desktop workspace.

See what we’re building

Our first product.

Our first product is taking shape. Here is a look inside the development workbench.

Oh My Own Code

One workspace for building with AI.

For independent builders

Keep project folders, sessions and reference files close to the conversation. Spend less time switching between disconnected tools.

Taking shape now

Workspace registration, session management, AI conversation controls and read-only file previews are implemented in development builds.

Next in development

Durable recovery, more complete workflows and native validation. macOS and Windows are target platforms; a public release is still ahead.

How Claude fits into the plan

We intend to evaluate Claude for coding, requirements analysis, documentation and testing, then integrate it into the workbench’s agent workflows. The current project uses an OpenCode runtime. A production Claude integration has not been released.

Built independently.
Built to be useful.

Stackline is a registered, founder-led software business based in South Korea. We started on December 23, 2025, and are building without outside investment.

Oh My Own Code is our current product. Our broader direction is to create and operate focused applications for individuals and small teams, using AI to support development.

We are still early. The screens above show development work, and our first public product release is ahead.
