Coding-agent web terminal
Use your coding agent from a browser.
Run Codex, Claude Code, OpenCode or another command-line agent on your machine. Use the browser to send prompts, check files and review Git changes. The agent keeps running when you disconnect.
Short answer
Can I run Codex or Claude Code from a browser?
Yes. Install tlbx on the machine that already has the repository and provider CLI, then launch that CLI inside a tlbx terminal. The agent authenticates and runs exactly as it does in a local terminal. tlbx does not proxy model requests or require a second agent account.
Keep the native setup
Install and authenticate the provider CLI normally on Windows, macOS or Linux.
Launch it in tlbx
Start the agent in its own terminal, beside your builds, tests and shells.
Reconnect when needed
Close the browser and return later. The host keeps the terminal process and retained output alive.
Your existing setup
Your agent uses your machine’s tools.
- Agent
- The normal provider CLI controls model selection, authentication, permissions and usage.
- Repository
- Source files and Git operations remain on the host machine where tlbx is installed.
- Terminal
- A native PTY preserves full-screen UI state, process lifetime and server-side scrollback.
- Browser
- tlbx adds terminal rendering, session switching, files, Git context and scoped browser controls.
One agent
Use one durable session when you only need to leave a long run alive or continue it from another browser.
Several agents
Give each agent its own session and checkout so you can follow its progress and keep edits separate.
Ordinary terminal work
The same workspace runs PowerShell, bash, zsh, editors, database shells, Git tools, builds and test watchers.
Common questions
Coding-agent web terminal FAQ
Does tlbx need my provider API key?
No. The provider CLI keeps its own authentication. tlbx runs and displays the terminal process.
Does tlbx upload the repository?
No. Files stay on the host unless you separately configure another tool or service to move them.
Does the agent continue when I close the browser?
Yes, while the host machine and tlbx service remain running. Sleep pauses the work; shutting down the host stops its processes.
Can I use more than one agent provider?
Yes. Each provider CLI runs in an independent terminal session and keeps its own native authentication and configuration.
