Coder Studio, made for vibe coding.
An agentic workspace for real development. Run, inspect, and supervise coding agents with terminals, files, Git, sessions, and review in one browser workspace.
Built-in support today: Claude Code and Codex. Your code and runtime stay on your machine.
- One browser workspace for real agent work — Keep terminals, files, Git, sessions, and review in one place.
- Built for device switching — Start on desktop, continue on tablet, and check progress from your phone.
- Keep control local — Your code and runtime stay on your machine.
Vibe coding agents are fast, but real development still gets fragmented:
- the agent runs in one terminal
- files and diffs live in another editor
- verification happens in separate shell tabs
- long-running tasks are hard to monitor away from your desk
- mobile access usually means SSH or remote desktop
Coder Studio turns that scattered workflow into one local browser workspace.
| Pain | Without Coder Studio | With Coder Studio |
|---|---|---|
| Long agent tasks | Watch a terminal or come back later and reconstruct context | Keep sessions, terminal output, files, and Git changes visible in one workspace |
| Cross-device work | Use SSH, remote desktop, or rebuild context on another machine | Reopen the same local workspace from desktop, tablet, or phone |
| Reviewing AI changes | Jump between terminal, editor, and Git tools | Inspect files and diffs beside the agent session |
| Multiple agents | Manage separate terminal windows and histories | Run built-in Claude Code and Codex sessions side by side in one workspace today |
| Local-first control | Move work into a hosted IDE or cloud VM | Keep the runtime and project files on your own machine |
# Install globally
npm install -g @spencer-kit/coder-studio
# Launch the workspace
coder-studio openYour browser opens automatically. Select your project folder and start working with Claude Code or OpenAI Codex today.
No AI CLI installed yet? You can still browse files and use the terminal. Install Claude Code or Codex later when needed.
- Start an Agent task at the office, check progress on your phone during commute
- Review code changes on a tablet without opening your laptop
- Continue work from a home computer with zero setup
- Let Supervisor push multi-step tasks toward an objective without constant babysitting
- Check evaluation cycles and follow-up actions from your phone instead of watching terminal output
- Reduce repetitive prompting and manual coordination during long agent runs
- Run Claude Code and Codex sessions side by side today
- Keep terminal, editor, Git, and supervisor state in one unified interface
- Resume active AI work from another device without rebuilding context
| Device | Best For |
|---|---|
| 🖥️ Desktop | Full coding sessions, file editing, diff review, panel management |
| 📱 Tablet | Code review, Agent progress tracking, file browsing |
| 📲 Phone | Quick status checks, terminal output monitoring, session viewing |
The same workspace URL works across all devices — interface adapts automatically.
