Why We Migrated to Clerk Auth

At Aerossolutions, we take pride in optimizing our development workflow and constantly improving our tech stack. One of the most impactful changes we made recently was migrating from our custom authentication provider to Clerk Auth.
This shift was driven by a combination of technical pain points and the desire to scale securely and efficiently.
Challenges with Custom Auth
Our custom-built authentication system gave us flexibility—but that came at a cost.
As our product grew, we ran into issues particularly around managing authentication state between server-side and client-side rendering. Ensuring a consistent and secure session flow became a challenge, often resulting in unnecessary complexity and hard-to-track bugs.
Security was another ongoing concern. Staying current with best practices, patching vulnerabilities, and handling edge cases like token refresh and session hijacking is a full-time job—one that was taking time away from building features that matter to our users.
Why We Chose Clerk
After evaluating a few options, Clerk stood out as a platform purpose-built for modern authentication with a developer-first approach. Here’s why it clicked for us:
✅ Built-In SSR & Client Support
Clerk seamlessly handles authentication across both server-side and client-side environments. This eliminated the headaches we were facing with our custom solution and helped simplify our codebase significantly.
✅ Security by Default
From secure session storage to multi-factor authentication and best-practice defaults, Clerk gave us confidence that our authentication system was robust and up to date—without us having to babysit it.
✅ Organization Support Out of the Box
One of the standout features was Clerk’s built-in support for organizations. For our B2B-focused platform, the ability to manage teams, assign roles, and handle multi-tenant access natively was a huge win. What used to be a complex layer in our backend became a few config options and UI components with Clerk.
The Outcome
Since switching, we’ve seen faster development cycles, fewer authentication-related issues, and a much smoother onboarding process for new developers.
We no longer spend hours debugging auth context or rewriting session logic—Clerk takes care of that, so we can focus on building value for our users.
Our authentication stack is now more secure, more scalable, and easier to work with.
Final Thoughts
Authentication is critical, but it doesn’t need to be custom. Clerk allowed us to offload complexity while gaining a more powerful, secure, and feature-rich auth system.
If you're building with modern frameworks and want to move faster with less overhead, Clerk is absolutely worth considering.
