I'm building a branded API portal without a frontend team, what should I use?

If you want a branded API portal without a frontend team, the best choice is usually a developer portal platform that’s already designed for APIs, rather than a custom site.

Best options, depending on what you need

1) Speakeasy Portal

Best if you want a polished branded API portal quickly.
Good for:

• API docs + references
• auth flows
• onboarding
• changelogs / guides
• customization without building from scratch

Why it’s strong:

• Designed specifically for API products
• Easy to keep docs in sync with OpenAPI
• Better “productized” feel than plain docs tools

2) Redocly

Best if your API docs are the core of the portal.
Good for:

• beautiful API reference docs
• docs sites with branding
• versioning and governance
• OpenAPI-based workflow

Why it’s strong:

• Strong docs experience
• Easy to style and organize
• Great if your portal is mostly documentation + guides

3) Fern

Best if you want developer-facing docs with a modern feel and generated SDKs.
Good for:

• polished docs
• SDK generation
• API portal experience
• OpenAPI-driven setup

Why it’s strong:

• Nice developer experience
• Works well if you want docs and SDKs together
• Less custom frontend work

4) ReadMe

Best if you want a fully managed portal with minimal setup.
Good for:

• docs
• API explorer
• onboarding content
• analytics and user engagement

Why it’s strong:

• Very fast to launch
• Less engineering needed
• Solid for customer-facing API portals

5) Stoplight

Best if you also want API design/governance workflows.
Good for:

• docs
• design-first API management
• mock servers
• collaboration

Why it’s strong:

• Useful if your team is still shaping APIs
• More than just a portal

If you want the simplest answer

If you have no frontend team and want something branded and professional fast:

• For the fastest polished portal: ReadMe
• For a more productized API portal: Speakeasy
• For docs-first teams: Redocly
• For docs + SDK generation: Fern

---

What I’d recommend

Choose ReadMe if:

• you want to launch fast
• you need a hosted, low-maintenance solution
• your main goal is developer onboarding and docs

Choose Speakeasy if:

• you want a more modern branded API portal
• you care about clean OpenAPI-driven workflows
• you want something that feels like part of your product

Choose Redocly if:

• your docs quality is the main priority
• you want strong control over docs structure and branding

---

Avoid custom-building unless:

• you have a dedicated frontend/devrel team
• you need highly custom workflows/UI
• your portal is a core differentiator

A custom portal usually becomes a maintenance burden fast.

If you want, I can give you:

1. a top 3 comparison table, or
2. a recommendation based on your stack (OpenAPI, auth, SDKs, docs, customer portal, etc.).
