Features and specs

What each product offers, as listed by its team.

ProtonMail 5 features

  • End-to-End Encryption
    ProtonMail uses robust end-to-end encryption, ensuring that only the sender and the recipient can read the emails. This enhances the security and privacy of your communications.
  • Zero Access to User Data
    ProtonMail does not have access to user data or emails. This means that even ProtonMail cannot read your emails, providing an additional layer of privacy.
  • Swiss Privacy Laws
    Based in Switzerland, ProtonMail benefits from stringent Swiss privacy laws, which are some of the strongest in the world. This offers users greater legal protection against mass surveillance.
  • Open Source

    ProtonMail offers an intuitive and clean user interface, making it easy for users to manage their emails efficiently.

Possible disadvantages

  • Limited Free Storage
    The free version of ProtonMail offers only 500 MB of storage, which might be insufficient for users who need to store a large number of emails.
  • Paid Plans
    Advanced features and additional storage require a paid subscription, which may be a hassle for users looking for a completely free service.
  • Search Limitations
    Due to end-to-end encryption, the search functionality in ProtonMail is limited compared to other email services, as the search can only be performed on email subjects, not the content.
  • Compatibility Issues
    ProtonMail's encryption might not be fully compatible with other email services, potentially causing issues with sending and receiving encrypted messages.

Questions & Answers

As answered by people managing ProtonMail and Coreframe Cloud.

What makes your product unique?

Coreframe Cloud's answer:

Coreframe Cloud rents full Windows desktops on NVIDIA RTX 5080 GPUs, streamed to any laptop and billed by the minute. Built for architects, interior designers, visualisation studios and CFD engineers who need workstation-class hardware for the hours they actually use it. Hosted in Bengaluru, billed in INR with GST included.

Why should a person choose your product over its competitors?

Coreframe Cloud's answer:

A whole dedicated RTX 5080, billed by the minute, priced in rupees with GST already included and a tax invoice you can claim input credit on — a combination we haven't found anywhere else in India. Most Indian GPU clouds sell headless Linux on datacentre cards to AI teams. Most cloud-workstation services that actually understand 3D work bill in dollars from outside India. Coreframe gives you a real Windows desktop with D5 Render, Blender, Twinmotion and Unreal Engine already installed, project files that persist between sessions, and billing that starts when the stream does and stops when you close it. Bring your own licence for Lumion, Enscape, Revit or 3ds Max — we provide the machine, never the licence

What's the story behind your product?

Coreframe Cloud's answer:

Coreframe Compute Labs was founded in Bengaluru in 2026 around a specific observation: the workstation an Indian design studio needs to render comfortably costs around ₹5,00,000 landed, gets bought once, and then sits idle most of the week. The cloud alternatives were either headless Linux boxes built for AI training, or foreign services billing in dollars with no Indian tax invoice. Neither suits someone who just wants to open Lumion and hit render. So we built the unglamorous version: a real Windows machine with a real GPU, hosted in Bengaluru, rented by the minute, with a GST invoice at the end of it.

Which are the primary technologies used for building your product?

Coreframe Cloud's answer:

The workstations are Windows 11 machines, each with a dedicated RTX 5080 (16 GB), streamed to your laptop over an encrypted private network with latency low enough for real-time viewport work. D5 Render, Blender, Twinmotion and Unreal Engine ship on the standard image, and project files persist in storage in the same Bengaluru facility. CFD runs on dedicated compute machines, one per job, which are deleted when the job finishes. Payments go through Razorpay, with GST invoices for Indian customers.

How would you describe the primary audience of your product?

Coreframe Cloud's answer:

Architects, interior designers and architectural visualisation studios, along with freelance 3D visualisers and students who need workstation-class hardware without buying it. A second group is HVAC and mechanical engineers who need pressure-drop numbers for ducts, pipes and fittings, including a three-mesh Verified study for when the answer has to stand up. The common thread is bursty work: heavy rendering or simulation before a deadline and very little after, which is exactly the pattern that makes owning a ₹5,00,000 machine hard to justify.
