Buyer's guide
Developer portal software for API-first teams.
A developer portal is the package of docs + SDKs + dashboards + recipes your customers see when they integrate. This page walks the categories, the trade-offs, and how to scope a portal that doesn't lock you in.

Categories of tools
**SDK + docs combined** — Bloom, Fern, Stainless, Speakeasy. One workflow, two outputs.
**Docs-first hubs** — Mintlify, ReadMe, GitBook, Bump.sh, Redocly. Strong reference; SDKs are a separate tool.
**OpenAPI governance** — Spectral, Stoplight Studio. Linting and review more than hosting.
**Self-built portals** — Astro / Next.js + OpenAPI plugins. Maximum control, maximum maintenance.

How to decide
If SDK quality is on the critical path: combined SDK + docs.
If docs are the product and SDKs are optional: docs-first.
If you have a strong design system and engineering time: self-built.
If governance matters more than hosting: governance tools complement either choice.
