Zuplo: vendor profile

In short

Zuplo's Developer Portal, built on Zudoku, is prerendered and writes a .md copy per page. It answers Accept: text/markdown with Vary: Accept, and llms.txt stays off until a setting turns it on. A portal page returned 4,256 bytes of markdown on 2026-11-05. The Free plan covers 100K requests a month.

What it does for this layer

Zuplo states that its hosted Dev Portal is prerendered to static HTML (SSG) by default; setting devPortal.serverSideRendering: true in zuplo.jsonc switches a deployment to per-request server rendering. [primary source] source, read 5 November 2026.
Server-side rendering for the Zuplo Dev Portal is sold only as an Enterprise add-on, used mainly so protected routes are enforced on the server; deployments with the flag but without the add-on fail. [primary source] source, read 5 November 2026.
In the Zuplo Dev Portal the per-page .md export (publishMarkdown) is on by default, while llmsTxt and llmsTxtFull are opt-in switches in the docs section of the Zudoku config. [primary source] source, read 5 November 2026.
Zuplo's llms.txt build leaves out redirect pages, the 400, 404 and 500 error pages, and protected routes unless includeProtected is set to true. [primary source] source, read 5 November 2026.
Zuplo's November 2025 monthly changelog announced llms.txt generation and markdown output for the Dev Portal, alongside a Copy page button. [primary source, 2025-12-01] source, read 5 November 2026.
Zuplo's changelog of 2026-08-28 added markdown on the normal page URL for Accept: text/markdown requests, sent with Vary: Accept so caches keep the two formats apart, starting with Zudoku 0.86.0. [primary source, 2026-08-28] source, read 5 November 2026.
The same Zuplo release lets a portal serve its processed OpenAPI file at a stable path through publish.path, and an agentQuality flag warns at build time about missing operationId values or untyped request bodies. [primary source, 2026-08-28] source, read 5 November 2026.
Zuplo's Dev Portal renders an OpenAPI document marked x-zudoku-type: mcp-catalog as one searchable page of MCP server cards with install instructions and tool lists. [primary source, 2026-08-28] source, read 5 November 2026.
Zuplo's x-zudoku-seo OpenAPI extension sets a tag page's title and meta description, and the docs say both are server-rendered into the prerendered HTML that crawlers see without JavaScript. [primary source] source, read 5 November 2026.
Zuplo's pricing page includes the developer portal in every plan: Free up to 100K requests a month, Builder at $25 per month, Enterprise from $1,000 per month on an annual contract. [primary source, 2026-11-05] source, read 5 November 2026.
On 2026-11-05 a Zuplo docs page (a Zudoku site) returned 200 text/markdown at 4,256 bytes for Accept: text/markdown with Vary: Accept, Accept-Encoding; its .md URL returned the same bytes without a Vary header. [observed, 2026-11-05] source, read 5 November 2026.
On 2026-11-05 the HTML of Zuplo's llms export doc page carried a schema.org TechArticle JSON-LD block, and a made-up path under zuplo.com/docs/dev-portal/ returned HTTP 404. [observed, 2026-11-05] source, read 5 November 2026.
