Considering Comfy Cloud annual plan — what limitations should I know about first?

I've been doing a deep dive into cloud ComfyUI options and wanted to share my findings + get some real-world input from people actually using Comfy Cloud before committing to an annual subscription.

What I've researched so far:

Comfy Cloud recently upgraded to RTX Blackwell 6000 Pro GPUs (96GB VRAM) and dropped prices 30% in January 2026, now billing at ~0.266 credits/second of active GPU time. The Standard plan (~$20/mo, 4,200 credits) works out to roughly 4.4 hours of active GPU time monthly. Credits are only consumed during actual execution, not while editing or waiting — which I like.

If you want to upload LoRas, you'll need the Creator plan (28 USD/m yearly)

I've also been looking at fal.ai's native Workflows UI (comfy.new) as an alternative — full ComfyUI in the browser, billed per GPU second (A100 ~$0.99/hr), no subscription needed. Tested it and it's surprisingly polished. The main pain point is cold starts — every new worker re-downloads your models, so a 160MB LoRA plus a 6GB checkpoint adds real overhead unless you keep runs tight within the keep_alive window.

Why I'm leaning toward Comfy Cloud:

• Official product, always latest ComfyUI version + supports the creators
• Partner Nodes (Sora, Veo, Kling, nano banana, Elevenlabs (just dropped)) all in one unified credit system — usable from local ComfyUI too
• No cold start headaches for casual use
• Bring your own LoRAs from CivitAI/HuggingFace (Creator plan+)
• API available

My use case:

Batch generating marketing assets (product images + short videos) for an e-commerce business. Workflows will be built locally, then executed in the cloud. With Comfy Cloud, this could all happen in the cloud.

Before I pull the trigger on the annual plan, a few things I haven't found clear answers on:

1. **Custom node support** — how limited is it really? The docs say "most popular nodes" but I've seen complaints about missing nodes. Has anyone hit a wall with a specific node pack that blocked their workflow?

2. **Workflow runtime limits** — Pro plan gets 60 min, Standard gets 30 min. Is 30 min actually enough for video workflows (Wan 2.2 etc.) or does it cut you off mid-generation?

3. **Queue wait times** — during peak hours, how long are you actually waiting before your workflow starts executing?

4. **Annual plan gotchas** — any billing surprises, credit rollover issues, or plan changes mid-year that screwed over subscribers?

5. **API access** — how usable is the Comfy Cloud API for programmatic batch runs from external tools (n8n, scripts)?

Would love to hear from anyone who's been on the plan for soeme time — especially if you're using it for production/batch workloads rather than just casual creative use.

Thanks in advance!
