The short version

  • Each has a real cost: Flax Engine flax charges a 4% royalty on game earnings above $250,000, assessed per calendar quarter; Perforce Helix Core the free tier covers only a handful of users, which maps badly onto how the product is actually used, because asset version control is needed by the whole studio, artists and audio staff included, not by the engineers alone.
  • They diverge on capability: Flax Engine covers 3D graphics rendering, Perforce Helix Core covers Exclusive checkout.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

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

Flax Engine

  • Flax charges a 4% royalty on game earnings above $250,000, assessed per calendar quarter
  • Free use is granted for non-commercial or educational usage; commercial releases fall under the royalty
  • Users must accept the Flax Engine End-User License Agreement before using the engine or its tools, so it is not an OSI open source licence despite the source being on GitHub
  • Non-game uses such as in-house tools or SaaS products need a custom licence negotiated with the vendor, and no rate card is published for per-seat or flat-fee options

Perforce Helix Core

  • The free tier covers only a handful of users, which maps badly onto how the product is actually used, because asset version control is needed by the whole studio, artists and audio staff included, not by the engineers alone.
  • Beyond the free tier pricing is quoted per seat and renewed annually, and it does not scale down for contractors or outsourcing partners who touch the depot for a single milestone and still consume a full licence.
  • It is centralised, so when the server or the connection to it is unavailable, work stops for everyone; edge servers reduce this but add another system to run.
  • Administration is a genuine role. Depot layout, streams, protections, proxies, checkpoints and backups all need someone who knows Perforce, and that person is expensive and hard to replace.
  • Exclusive checkout prevents merge conflicts on binaries but blocks colleagues outright; a file locked by someone on leave needs administrator intervention, which turns a holiday into a production stoppage.

Answered from the vendors’ own pages

Flax Engine: How much does Flax Engine cost?

Flax Engine is free during development. Once you ship a game commercially, you pay a 4% royalty on earnings only if your quarterly revenue exceeds $250,000 in a calendar quarter. Below that threshold, there is no royalty charge.

Source
Perforce Helix Core: Why not just use Git with LFS?

Git assumes text files that merge and a full local history. Game projects have terabytes of unmergeable binaries. LFS handles the size but not the locking or the clone time, which is why studios past a certain size move to Perforce.

Flax Engine: Is Flax Engine free for educational and uncommercial projects?

Yes. Flax Engine is free for uncommercial or educational usage. You only pay royalties when you release a commercial product that exceeds the $250,000 quarterly earnings threshold.

Source
Perforce Helix Core: How much does it cost?

Perforce does not publish prices. It is free for a small number of users and workspaces, after which licensing is quoted per user annually and depends on volume and support level.

Flax Engine: Do all Flax Engine users get access to the same features?

Yes. There is one version of Flax Engine. All users get full engine access with all features, supported platforms, complete editor source code on GitHub, sample projects, and free deployment to all supported platforms.

Source
Perforce Helix Core: Can programmers keep working in Git?

Partly. Helix4Git bridges Git repositories into the Helix Core depot, but it is another component to run and does not remove the difference in workflow between the two systems.

Flax Engine: Does Flax Engine offer custom licensing options?

Yes. For non-game industries or specific needs, Flax Engine offers custom licensing including per-seat licensing (monthly or yearly) or flat fees per project, with pricing based on team size and product use case.
