Event Horizon

Event Horizon is a customizable API catalog template with a sleek, galactic theme and a luminous black-hole hero graphic. The bold, industry-agnostic design gives any API suite a distinctly cosmic edge, and every color, icon, and layout block is editable in Theneo's low-code editor, so teams can launch a striking developer portal or catalog without writing code.

How to customize it

Every color, icon, and layout block is editable in Theneo's low-code editor, so the cosmic styling is a starting point rather than a commitment. Import your OpenAPI, Swagger, Postman, or GraphQL specification and the catalog populates automatically. See the developer portal overview for the full customization range.

Frequently asked questions

Do I have to keep the space theme?

No. Every color token, icon, and graphic is editable, so the layout works with any visual identity.

Which API specifications does this template support?

OpenAPI 3.x, Swagger 2.0, Postman collections, GraphQL schemas, and gRPC. Theneo generates endpoint descriptions, code samples, and interactive examples from your specification.

Can I publish it on my own domain?

Yes. Custom domains are supported with full white-label branding, so the portal looks like your product rather than a third-party tool.
