Our first product is taking shape. Here is a look inside the development workbench.
Oh My Own Code
One workspace for building with AI.
Development preview
Latest development build, October 2026, captured by our automated UI tests with synthetic test data. Permission mode and composer controls appear before a request is sent.
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.
Built with Claude
We develop Oh My Own Code with Claude Code running Claude Opus, for planning, implementation, code review and tests. Commits produced this way carry a Claude co-author trailer in our repository. Next, we plan to bring the Claude API into the workbench’s agent runtime, which currently runs on OpenCode, for coding, documentation and testing workflows. A production Claude integration has not been released yet.
Built independently. Built to be useful.
Stackline (스택라인) is a registered software business in Namyangju-si, South Korea, founded and led by Hyukjae Choi. Our business registration (IT services) is dated 23 December 2025. 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.
