On small viewports, the agent chat page showed the wrong panel. The right panel filled the screen and hid the chat. before: https://github.com/user-attachments/assets/fa3986b8-949a-4aad-8e98-d64316ade3f5 after: https://github.com/user-attachments/assets/bc56359d-2ffe-4f95-b47b-638261379da8 ## Changes - Below the `lg` breakpoint, the page shows one panel at a time. A right panel left open on a wide window used to hide the chat when the window narrowed. The page now shows the chat. - The panel preference is not changed by a resize. When the window widens, the panel comes back. When the user taps a tab while narrow, the panel opens as before. ## Tests - Unit tests for the new `useRightPanelNarrowSuppression` hook cover mount, both breakpoint crossings, and the explicit override. - A new mobile-viewport story asserts the chat is visible when a panel was left open. <details> <summary>Decision log</summary> - The right panel's open state persists in localStorage across all viewport sizes. `max-lg:hidden` on the chat made that stale state hide the chat on narrow windows. - The narrow suppression is transient state, not a write to the persisted preference. A temporary resize keeps the user's desktop layout intact. - The hook adjusts state during render (the React "adjusting state when a prop changes" pattern) instead of an effect, per FE8. - Verified all resize sequences live against a dev deployment: narrow with a panel open, widen to restore, drill in while narrow, and explicit close while narrow. </details> 🤖 This PR was created by [Coder Agents](https://coder.com/docs/ai-coder/agents) on behalf of @bpmct. --------- Co-authored-by: Michael Suchacz <203725896+ibetitsmike@users.noreply.github.com>
Coder is a self-hosted platform for cloud development environments and AI coding agents. Workspaces are defined with Terraform, connected through a secure Wireguard® tunnel, and automatically shut down when not used. Coder Agents runs a native AI coding agent whose loop executes in the control plane on your infrastructure, with no API keys in workspaces.
- Define cloud development environments in Terraform
- EC2 VMs, Kubernetes Pods, Docker Containers, etc.
- Automatically shutdown idle resources to save on costs
- Onboard developers in seconds instead of days
- Delegate coding work to AI agents on your infrastructure
- Bring any model (Anthropic, OpenAI, Google, Bedrock, self-hosted)
- No LLM credentials in workspaces, user identity on every action
- Centralized model governance, cost tracking, and audit logging
Quickstart
Check out our install guides for other methods and a complete tutorial.
Try Coder with the install script on Linux and macOS, or grab the latest binary or installer from GitHub Releases on Windows:
curl -L https://coder.com/install.sh | sh
Start the server and open http://localhost:3000 to create your initial user, create a Docker template, and provision your first workspace:
coder server
For a production deployment, add a PostgreSQL database (version 13 or later) and an external access URL, and see our validated architectures for sizing and infrastructure guidance:
coder server --postgres-url <url> --access-url <url>
Without these flags, Coder uses a built-in database and sets up a *.try.coder.app access URL for evaluation. Use coder --help for the full list of flags and environment variables.
