An Exciting New Chapter: Permify Joins FusionAuth

Permify started with a straightforward goal — to make authorization simpler, clearer, and easier for developers to build and maintain. We created it because the tools available weren’t keeping up with the way modern applications were evolving. Developers were left choosing between fragile, homegrown permission code or solutions that couldn’t model real-world complexity.

So we built Permify as an open-source authorization engine inspired by Google Zanzibar — Google’s model for large-scale, fine-grained permissions — with a focus on clarity, consistency, and modern architecture. And from the beginning, our community has been at the heart of the project. Your feedback, contributions, and real-world use cases shaped Permify into what it is today.

Today, we’re excited to share the next step in that journey: Permify has been acquired by FusionAuth.

This is a meaningful milestone. Not just for our team, but for everyone who has been part of the Permify community. We want to share why this move is the right next chapter.

Why FusionAuth is the Next Step in Permify’s Evolution

FusionAuth is a company built by developers, for developers. They understand what it means to build things with complete control:

• deploy anywhere
• keep your data
• customize everything

They’ve invested heavily in their free Community Edition, documentation, SDKs, and developer relations team.

Their philosophy closely matches ours: developers deserve visibility, choice, and ownership — not black boxes.

When we started speaking with their team, it quickly became clear that our DNA matched. Permify’s fine-grained authorization engine is a natural complement to FusionAuth’s authentication platform. Together, we can solve the full identity and access lifecycle in a unified, transparent, deploy-anywhere way.

Most importantly: Permify Remains Open Source. And the Community Remains at the Center

We know the first question many of you will have is: “What happens to the open-source project?”

The answer is simple:

• Permify stays open source.
• The community stays active and supported.
• FusionAuth is committed to investing in it.

FusionAuth has a long track record of supporting developers through both their Community Edition and DevRel program. They’ve built a global community by being transparent, responsive, and respectful of developer autonomy.

With their backing, we’ll be able to:

• Improve documentation and examples
• Respond faster to issues and PRs
• Expand integrations
• Support more complex use cases
• Invest in long-term roadmap items we couldn’t tackle alone

This acquisition isn’t the end of the Permify project — it’s how we take it further than we ever could as a small team.

So, What Happens Next?

A few things we can share today:

• The core Permify project remains open source and will continue to live on GitHub.
• Members of our team will continue working on Permify, collaborating with FusionAuth’s engineers, DevRel, and product teams.
• We’ll begin designing a clean integration path between FusionAuth (AuthN) and Permify (AuthZ).
• Nothing changes for existing users or contributors — your workflows stay the same.
• Permify will continue to be available as a standalone authorization engine.
• More roadmap details will be shared early next year as our unified plan comes together.

Together with the FusionAuth team, we will continue talking directly with you, sharing updates, and asking for feedback openly — just as we always have.

A Thank You to the Community

Permify exists because developers believed in the idea of a better approach to authorization. Many of you were early adopters, experimenters, skeptics who pushed us, or contributors who made the project better in ways that truly mattered.

We built the foundation — but you built the momentum.

And now, with FusionAuth, we’ll have the resources and support to take this project to the next level, without losing the openness, transparency, or values that made it worth building in the first place.

Onward. Together.

We’re incredibly excited for this next evolution. Thank you for your support, your ideas, your contributions, and your patience as we take this big step.

If you have questions, thoughts, or feedback, we want to hear from you — as always. This is just the beginning of what we can build together.
