The short version

  • Only GNU Emacs has a free tier, so it costs nothing to try first.
  • Each has a real cost: GNU Emacs steep learning curve for its default keybindings and Lisp-based configuration.; Very Good Security vGS sits in the live path of every request carrying sensitive data, so its latency and availability become yours, and an outage in the proxy is a payment outage no matter how healthy your own systems are.
  • They diverge on capability: GNU Emacs covers Emacs Lisp Extensibility, Very Good Security covers Aliasing proxy.
  • Prices and features above were last checked on 31 August 2026.

Very Good Security

  • A card issuer that must display a full PAN in its own mobile app without the app or its backend touching cardholder datanot GNU Emacs

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

GNU Emacs

  • Steep learning curve for its default keybindings and Lisp-based configuration.
  • Default UI looks dated compared to modern editors without heavy customization.
  • Performance can lag on very large files compared to newer editors.
  • Discoverability of features is poor without prior familiarity or external guides.

Very Good Security

  • VGS sits in the live path of every request carrying sensitive data, so its latency and availability become yours, and an outage in the proxy is a payment outage no matter how healthy your own systems are.
  • Token portability is the whole selling point yet leaving VGS means migrating tokens back out, a project the vendor has no incentive to streamline, so the lock-in you removed from your acquirer partly moves to VGS.
  • Entry pricing at around one thousand US dollars a month is real money for a pre-revenue fintech, and it buys volume-limited throughput, so cost scales with exactly the growth that made you buy it.
  • Scope reduction is not scope elimination: your QSA still assesses how you integrate, and teams regularly discover that a support tool or an internal admin screen pulled plaintext back in and dragged systems into scope again.
  • Proxy-based interception constrains how you design request flows, and non-standard payloads, streaming uploads or binary formats often need custom routing rules that make debugging production issues noticeably harder.

Yes, Emacs is free software released under the GNU General Public License, which allows anyone to use, study, modify, and redistribute it, including commercially.

Source
Very Good Security: Does VGS make me PCI compliant?

No. It removes cardholder data from your systems so your assessment covers a far smaller boundary, but you still complete an assessment and your integration is part of it.

On Linux it is available via package managers like apt-get, pacman, dnf, or zypper; on macOS via Homebrew or MacPorts; on Windows via an installer or zip from GNU mirrors; and on Android via F-Droid or GNU FTP.

Source
Very Good Security: Can I move to another processor without re-collecting cards?

Yes, that is a core reason people buy it. The vault reveals stored credentials to whichever processor you route to.

GNU Emacs: What platforms does Emacs support?

Emacs runs on GNU/Linux, FreeBSD, NetBSD, OpenBSD, Haiku, macOS, MS Windows, Android (versions 2.2 to 15.0), Solaris, and MS-DOS/FreeDOS.

Very Good Security: What does it cost?

Published entry pricing is about one thousand US dollars per month; growth and enterprise tiers are quoted.

GNU Emacs: How is Emacs extended with packages?

Emacs is customized and extended through its Emacs Lisp dialect, with thousands of community packages distributed via repositories like MELPA that add language modes and tools.

Source
Very Good Security: Is it only for card data?

No. The proxy handles any sensitive field, including bank details, national identifiers and documents, though payments is where the product is now focused.

GNU Emacs: Where can I get source code or development builds?

Emacs source code and development builds are hosted at savannah.gnu.org, in addition to stable releases distributed through GNU mirrors.
