Comfy Cloud Builds page paste workflow deploy endpoint web UI
💡 Result:
Comfy Cloud provides a streamlined workflow to transform ComfyUI projects into production-ready, serverless API endpoints [1][2][3]. To deploy a workflow as an API, you can use either the Web UI or the Developer Platform API [2]. Using the Web UI: 1. Navigate to your saved workflows within the Comfy Cloud interface (e.g., in My Workflows or the Explore section) [2]. 2. Select the desired workflow [2]. 3. Choose the option to Deploy as an API [2]. 4. Configure the required hardware and scaling settings, then finalize the deployment [2]. 5. Once deployed, the system will provide you with a unique deployment_id [2]. Using the Developer Platform API: Alternatively, you can automate this process via the Comfy Developer Platform API [2]. Workflows deployed through this platform receive a dedicated endpoint (typically at https://{deployment}.run.comfy.app) that supports the Comfy v2 API [1]. This allows your applications to programmatically submit prompts, manage execution, and retrieve results using your API key [1][4][5]. Key Workflow Components: - Workflow Execution: Once deployed, you interact with your endpoint by submitting JSON-formatted workflow graphs to the /api/prompt endpoint [6][4][5]. - Compatibility: Deployed serverless endpoints run the same v2 API as Comfy Cloud [1]. - Workflow Management: You can also use the Comfy CLI (comfy run) to manage workflows, which can automatically handle the conversion of UI-format workflows to API format and route them to your cloud or local environment [7]. For authentication, ensure you have generated an API key from your account settings at the Comfy platform profile page, which is passed in the X-API-Key header [4][8].

site:docs.comfy.org OR site:platform.comfy.org Builds paste workflow dedicated endpoint Comfy Build deploy web UI
💡 Result:
ComfyUI does not have a single "paste workflow" dedicated endpoint for deploying to the web UI; rather, it provides a comprehensive API architecture for submitting, monitoring, and managing workflow executions [1][2]. If you are looking to integrate or deploy workflows, you should use the following patterns based on your specific goal: For Serverless/Cloud Deployments: When you deploy a workflow through the Comfy Developer Platform, it receives a dedicated, versioned API endpoint (e.g., https://{deployment}.run.comfy.app) [1]. This endpoint supports the v2 API, allowing you to submit jobs, poll for status, and retrieve results using standard HTTP requests [1][3]. For Self-Hosted Custom Integration: If you are running ComfyUI locally or in a self-hosted environment and need to trigger custom logic or workflow handling, you have two primary options: 1. Custom Server Routes: You can add custom endpoints to the ComfyUI server by using the PromptServer instance in your own Python code [4]. python from server import PromptServer from aiohttp import web routes = PromptServer.instance.routes `@routes.post`('/my_new_path') async def my_function(request): the_data = await request.post() # Process the workflow or data here return web.json_response({"status": "success"}) 2. API-Format Submission: For standard workflow execution, submit your API-format workflow graph to the /api/prompt endpoint (or /api/v2/jobs for the v2 API) [3][5]. If your goal is to programmatically "paste" or load a workflow into the ComfyUI browser interface (the Web UI), note that the Web UI communicates primarily via WebSockets and internal events [4]. There is no public, documented "paste" endpoint that forces a UI state change externally; however, most automation is handled by programmatically submitting the workflow to the server backend, which the UI then monitors via the /ws WebSocket endpoint [4][6]. For more details on interacting with the backend, refer to the official Comfy documentation on server routes and the v2 API reference [4][1].

Correct the "Paste Workflow and Deploy" step; it still misdescribes the Builds flow.
Step 3 says "Paste the workflow, deploy the endpoint, then copy its URL," linked to "Open builds." The real Comfy Build flow has no single paste-and-deploy action. A reviewer already flagged this. Describe the actual web UI flow, or list the CLI Build, Release, Deploy, and Run stages separately.
Also applies to: line 84, line 121, and the Note at line 130 ("paste it into the Builds flow").
Get this step right, or your readers will paste and pray instead of ship with flair.

State the Comfy Cloud API access requirement.
An API key alone is not the full prerequisite. The Cloud API documentation requires an eligible subscription. Add that requirement before the deployment step so users do not deploy an app that cannot call the API. (docs.comfy.org)

HTML inert attribute focused element becomes inert focus behavior specification
💡 Result:
According to the HTML specification, when an element that is currently focused becomes inert, it loses its focus [1][2][3]. The browser effectively performs a focus fix-up to ensure that focus is moved away from an element that can no longer be focused [3][4]. When an element becomes inert, the following behaviors are enforced by the user agent [1][2][5]: 1. Focus and Interactivity: The element and its flat tree descendants cannot be focused, and they cannot receive click events (as if pointer-events were set to none) [1][2][5]. 2. Focus Fix-up: If an element that currently holds focus becomes inert, the user agent will move the focus [3]. Typically, the user agent will move focus to the body element if no other element is explicitly focused in its stead [4]. 3. Accessibility: The element and its descendants are removed from the accessibility tree, effectively behaving as if they had aria-hidden="true" [2][6][5]. 4. Other Restrictions: The content becomes unselectable by the user, cannot be edited (including within contenteditable areas or form fields), and is ignored by browser "find-in-page" search features [2][7][5]. The inert attribute is designed to provide a reliable, standardized way to make DOM subtrees non-interactive, which simplifies tasks like managing modal dialogs and preventing focus trapping [6][5]. Because inertness is inherited down the flat tree and cannot be overridden by descendants, it is intentionally simple to reason about—if an ancestor is inert, the entire subtree is inert [3].

Add a Demo Apps entry to the Developers sidebar and a wide visual card directory for the current Comfy examples. Each card offers Comfy Cloud or Deploy Your Own, then rotates horizontally to the selected path's sample-specific steps. Constraint: Existing example source and workflow downloads retain their GitHub access controls Constraint: Demo card interaction must remain compatible with Mint's MDX hydration model Rejected: Direct external deployment links only | Users need the API key, workflow, Build, and endpoint handoff before leaving the page Rejected: Page-defined MDX components | Mint removes them from its client no-JS rendering pass Confidence: medium Scope-risk: narrow Reversibility: clean Directive: Keep the Comfy Cloud and Deploy Your Own paths aligned with the provider templates and Developer Platform Builds flow Tested: Mint local preview; actual browser card flip checks; MDX parse; SVG asset HTTP checks; verified Discord Render repository; git diff --check Not-tested: External Vercel, Render, and Developer Platform authenticated handoffs; zoomed or translated reverse-card layouts
