Six steps.
1. Create an account.
Sign up with your email address. Choose Individual if you're a freelancer or working on your own projects, or Business if you're GST-registered and need invoices in the company's name. A business account also asks for your registered name and GSTIN, which then appear on every tax invoice.
2. Confirm your mobile number.
We send a one-time code to your mobile on WhatsApp. Indian regulations (CERT-In) require a verified contact number for anyone renting compute, so this comes before a workstation can start. Any country code works, and there are no ID documents to upload.
3. Add credit.
Top up your wallet from the website or the app by card, UPI or netbanking. International cards work too. New customers get an intro offer on their first top-up, and the current terms are on the Pricing page. Pay-as-you-go has no setup fee and no monthly minimum. Business accounts can be invoiced monthly instead of prepaying.
4. Install Coreframe Connect.
Connect is the Windows client. It handles the private network link and the stream, so there's nothing else to set up. Download it from your account, run the installer and sign in. The installer is signed by Coreframe Compute Labs Private Limited, so Windows shows our name as the publisher.
5. Press Connect.
Pick your machine and press Connect. A workstation is prepared for you and the desktop appears in about two minutes, streamed at 4K at 60 fps. Billing starts when you connect. If you don't connect within 10 minutes of your workstation being ready, it shuts down and those 10 minutes are charged. If a connection fails on our side, nothing is charged.
6. Work, then end the session.
You get a full Windows desktop with the professional applications already installed. Your storage is mapped as drive N:, labelled Coreframe Datalake. Save project files there and nowhere else. When you're done, end the session from Connect. Billing stops right then, and everything on N: stays where you left it. You can also close the stream, or switch off your own computer, and leave your work running. The session keeps running, and billing continues, until you end it in Connect or your wallet runs out.
Installing on Windows.
Connect is code-signed by Coreframe Compute Labs Private Limited. When Windows asks whether to let the installer make changes, the publisher shows as our company name. Click Yes.
To check the signature yourself, right-click the downloaded file, choose Properties, then open the Digital Signaturestab. It should list Coreframe Compute Labs Private Limited. If it lists anyone else, or has no such tab, don't run it and message us instead.
On first connect, Windows asks to allow Connect's private network link and firewall access. Click Yes. You only see these once.
Read this before your first session.
The workstation resets between sessions. Software you install, and anything left on the Desktop, in Documents or on C:, is wiped when you finish. Only drive N:, labelled Coreframe Datalake, survives. Save your work there and you won't lose any of it.
That reset is why every session starts on a clean, identical machine. Nothing is left over from the customer before you, and nothing of yours is left for the customer after.
Common questions.
What is Coreframe?
Coreframe rents Windows GPU workstations by the minute, hosted in India. You stream a real Windows desktop, with the applications already installed, to the laptop you already own through the Coreframe Connect app (no browser, no terminal) and use it like a workstation under your desk, for D5 Render, Lumion, Enscape, Revit, 3ds Max, Blender, CFD work or anything else that needs a GPU. You drive the machine yourself. There's no job queue, because it isn't a render farm, and it isn't a Linux GPU server you reach over SSH: if you need root, SSH or Linux, a GPU cloud built for AI is the better fit.
How is Coreframe billed?
Per minute. Billing starts when you connect and stops when you end the session. If you close the stream and leave work running, on the GPU or the CPU, the session keeps running and is billed until you end it in Connect or your wallet runs out. So remember to end it when you're done. Preparing the workstation and uploads are free. If you don't connect within 10 minutes of your workstation being ready, it shuts down and those 10 minutes are charged. If a connection fails on our side, nothing is charged. Prices include GST, and you get a tax invoice for every payment.
Do I need my own software licences?
For commercial applications, yes. Lumion, Enscape, V-Ray, Revit, AutoCAD, 3ds Max and the like are licensed to you, not the machine, so we set them up with you once and you sign in with your own subscription. Already installed: D5 Render (you sign in with your own D5 account), Blender, Twinmotion, Unreal Engine, the Autodesk viewers and the usual utilities.
Can I install my own software on the workstation?
We install the applications for you. Your session runs as a standard Windows user, which is how we can promise the machine goes back to a clean image before the next customer, with nothing you or anyone else ran surviving the reset. Portable software that doesn't need an installer will run. If you need an application we don't carry, email admin@coreframecloud.com. We add free software to the standard image, usually the same day. Licensed software from Autodesk, Chaos or Lumion needs your own account even to download, so we arrange a short setup session with you. After that it's on every workstation you launch.
Where exactly do I save my files?
On drive N:, labelled Coreframe Datalake. It's mapped for you before the desktop appears, and it's the only place that survives the session. The Desktop, Documents, Downloads and the whole C: drive are wiped when you finish, along with anything you installed. If your project uses linked assets (D5 Render, Twinmotion and 3ds Max all do), keep the whole project folder on N:, not just the scene file. Otherwise the links break as soon as the textures point somewhere that no longer exists. The easiest habit is to Save As to N: right at the start, so every later save lands in the right place.
Why is the workstation wiped between sessions?
So every customer starts from an identical, clean machine and nothing from anyone else's work can reach them. If your projects are under NDA, that's what you want. The previous session can't leave files, credentials or browser history behind for you to find, and yours can't leave anything for the next person.
What internet speed do I need?
4K at 60 fps looks its best on about 50 Mbps and still holds up at 35 Mbps. 1080p is comfortable on 20 Mbps. A steady connection matters more than raw bandwidth. Streaming is more sensitive to latency and jitter than to throughput, so a wired connection or 5 GHz Wi-Fi beats a quicker link that drops packets.
Can my whole studio use one account?
No. Each person needs their own account, because the sign-in and contact record are per person. A business account holds the whole team under one organisation, with a shared wallet and a shared drive, so you get one bill and one place to manage seats while everyone signs in as themselves.
Where are the machines located?
In India, and only in India. The control server is in Panvel, Maharashtra, the GPU workstations are in Mumbai, in a data centre whose operator publishes an Uptime Institute Tier III certification, and your project files sit on our own NAS. That keeps latency low for Indian users, and it means your data and your invoices stay within Indian jurisdiction.
How do I get my files onto the workstation?
Upload them to your Coreframe storage from the app or the website before the session, and they'll be on the mapped drive when the desktop appears. You can also download straight into the session from cloud storage you already use.
