Build custom IAM extensions in Go with IdentityPlane to tailor authentication, registration, social login, and passwordless flows.
Build the IAM You Need with Custom Extensions
Your authentication stack should adapt to your systems, not the other way around. IdentityPlane lets you extend and integrate your identity flows with the tools and services you already rely on, using a clear, industry proven model for custom IAM.
With IdentityPlane, you can plug in your own logic, data sources, and integrations without losing control of security or user experience. You design how authentication and registration should work, then back it with extensions written in Go that run where you need them to run. If you need help building or integrating those extensions, our team can work directly with your developers to design, implement, and deploy them.
Extend Identity Without Rewriting Your Stack
IdentityPlane custom extensions give you a direct way to connect IAM to your existing applications, APIs, and infrastructure. Instead of bending your systems to fit a rigid identity product, you can implement exactly the behavior your teams and users expect.
Custom IAM with IdentityPlane means you can add new providers, transform claims, call internal services, and enrich user context during authentication and registration. All of this lives alongside the open-source core, so your extensions stay transparent and under your control.
Key ways you can use custom extensions:
• Integrate with internal APIs, directories, or data stores for authentication and profile data
• Implement custom business rules and approval logic in user flows
• Add or modify social, passwordless, or enterprise login behavior
• Normalize and transform identity data before it reaches your applications
• Connect third-party tools, monitoring, and security services into your IAM flows
By keeping the extension surface clear and composable, IdentityPlane lets you iterate quickly while keeping your login flows predictable and testable. If required, we can support you with design reviews, extension implementation, and integration testing to fit your environment.
How Custom Extensions Work in IdentityPlane
IdentityPlane is built for extensibility from the start. You define authentication and registration journeys using graph-based flows, then attach custom nodes backed by Go code where you need application-specific behavior.
Extensions can call out to external systems, apply custom validation, or adjust what gets written to user profiles and tokens. Since everything is defined as part of the same graph, you keep a single, consistent view of your IAM logic instead of scattering it across services.
As your requirements change, you can update or add new extensions without rebuilding the entire platform. This keeps your custom IAM implementation maintainable and easier to reason about over time. If you prefer not to handle all of this in-house, we can help with extension development, integration, and rollout so your team can focus on core application work.
Why Developers Choose IdentityPlane for Custom IAM
IdentityPlane is built for teams that want clarity and control in their identity layer. Instead of a black-box identity service with limited hooks, you get an open-source core, graph-based flows, and extension points designed for real-world integration work.
We focus on making complex authentication setups understandable for developers: explicit flows, predictable extension behavior, and the option to run IdentityPlane in the way that fits your organization, from open-source deployments to managed options. You keep ownership of your logic, your data paths, and your user experience.
If you need custom IAM that plugs cleanly into your stack and grows with your architecture, IdentityPlane gives you the building blocks to design it, own it, and extend it on your terms, with support available for end-to-end extension development and integration when needed.
