NextChat is a light, fast AI assistant UI with GPT, Claude, DeepSeek, and Gemini support.
Launch in your Sealos workspace.
Start with the resources defined by the chatgpt-next-web template. Review CPU, memory, persistent storage, and network allocations for every service in Canvas. Capacity needs depend on your data and workload; monitor usage as they grow.
Template configuration and setupUse the application URL or connection details shown in Canvas. Follow the deployment guide for first-time account setup or client configuration, and keep generated credentials available for that step.
Sealos monthly plans include compute, memory, storage, and traffic. Size your plan for all deployed services. Software licenses and external AI or API services may have separate terms and charges. Confirm the applicable plan and optional charges in Cost Center.

NextChat is a lightweight AI assistant web UI for OpenAI-compatible providers, Azure OpenAI, Claude, DeepSeek, Gemini, and other model gateways. This template deploys the official NextChat container with HTTPS access on Sealos Cloud.
NextChat runs as a single web application and stores chat state in the browser. The Sealos template creates a Deployment, Service, Ingress, and App entry, then injects model-provider settings through deployment inputs.
Access control is handled by the required CODE input. The template generates a unique default code, and users enter one of the comma-separated access codes on the first screen.

Store private API keys and access codes in Sealos-managed inputs. Keep CODE private because the public HTTPS endpoint uses the deployment's server-side model API key.
The template is tuned for a small single-instance web UI. Increase CPU and memory from Sealos Canvas if many users share the same deployment or if the UI serves through a slower model gateway.
Check that the value entered in the browser matches one of the comma-separated values in CODE, then restart the Deployment after changing the input.
Verify OPENAI_API_KEY, BASE_URL, Azure settings, and model-provider rate limits. For OpenAI-compatible gateways, confirm that the gateway supports the selected model names.
Set ENABLE_BALANCE_QUERY to 1 and restart the Deployment.
