Since APIs.json version 0.19, artifacts like OpenAPI definitions and Arazzo workflows can be embedded inline as data properties, meaning a single file can describe an entire API collection. The tool renders link properties as cards, full OpenAPI references with operations and schemas, and Arazzo workflows as step-by-step timelines. It supports specification versions 0.11 through 0.21 and flags version mismatches. The viewer can be hosted, run locally alongside an apis.json file, or bundled as a single self-contained HTML file that works offline — emphasizing portability and long-term ownership of documentation without platform dependency. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How do I generate HTML documentation from an APIs.json file without running a server? Use the API Documentation tool at documentation.apicommons.org, which renders any APIs.json file as readable HTML entirely in the browser with no backend, account, or data leaving the browser. You can drop a file in, point it at a URL with a ?url= parameter, rename the viewer to index.html and place it next to your apis.json, or inline the document into a single self-contained HTML file that works offline. _Developers documenting API collections can track tools like this for offline-first, portable API docs on daily.dev._ ### What changed in APIs.json version 0.19 that lets it embed OpenAPI and Arazzo files directly? Since version 0.19, APIs.json can carry the artifacts themselves inline as data properties, meaning full OpenAPI definitions, Arazzo workflows, prompts, and rules can live inside the index instead of being scattered behind links that can rot. This lets a single file describe an entire API collection, which is what enables tools like the API Documentation viewer to render complete docs from one file. _Teams standardizing on APIs.json can follow format changes like this via daily.dev to keep indexes and tooling in sync._ ### Which APIs.json specification versions does the API Documentation tool support? The tool reads every specification version from 0.11 through 0.21, and it will flag when a document uses fields newer than the version it declares itself to be. This makes it useful for validating older APIs.json files against the fields they actually contain versus the version they claim. _Maintainers auditing old apis.json files can watch for compatibility tooling updates like this on daily.dev._ ## Community discussion Top comments from developers on daily.dev. **@bits\_and\_bytes** · 1 upvotes > The single self-contained HTML file approach is underrated. We've hosted internal API docs in S3 buckets before and the platform dependency always became a maintenance problem eventually. This sidesteps that entirely. ## Similar posts on daily.dev - [A Browser-First Governance Validator for Your API Specs](https://daily.dev/posts/a-browser-first-governance-validator-for-your-api-specs-3lcv3xewd) · API Evangelist · 0 upvotes · 0 comments - [Swagger In A Box: NPM, APIs, and Swagger Codegen](https://daily.dev/posts/swagger-in-a-box-npm-apis-and-swagger-codegen-ks4ldkveh) · Atomic Spin · 6 upvotes · 0 comments - [Arazzo: The Missing Piece for AI-Assisted API Consumption](https://daily.dev/posts/arazzo-the-missing-piece-for-ai-assisted-api-consumption-gh73ztl8k) · marmelab · 3 upvotes · 0 comments - [Bringing Legacy Standards Into the Modern API Age](https://daily.dev/posts/bringing-legacy-standards-into-the-modern-api-age-kinikljok) · API Evangelist · 1 upvotes · 0 comments - [JSON Alexander Gives Developers a Simpler, More Trustworthy Way to View JSON in the Browser](https://daily.dev/posts/json-alexander-gives-developers-a-simpler-more-trustworthy-way-to-view-json-in-the-browser-dnjrdpjwr) · Laravel News · 3 upvotes · 1 comments --- Tags: [#architecture](https://daily.dev/tags/architecture), [#backend](https://daily.dev/tags/backend), [#openapi](https://daily.dev/tags/openapi) [View this post on daily.dev](https://daily.dev/posts/standalone-api-documentation-generated-from-apis-json-s7anei9d4) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Standalone API Documentation Generated From APIs.json","url":"https://daily.dev/posts/standalone-api-documentation-generated-from-apis-json-s7anei9d4","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/standalone-api-documentation-generated-from-apis-json-s7anei9d4"},"datePublished":"2026-07-09T13:27:49.817Z","dateModified":"2026-09-14T07:24:52.695Z","description":"API Commons has released a standalone API documentation tool that takes an APIs.json file and renders it as readable HTML entirely in the browser — no backend,...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/7fd471d248be9202814c6542005d0791?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/7fd471d248be9202814c6542005d0791?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"API Evangelist","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"API Evangelist","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1/logos/a36244ae67bc4f41a605f780267ecb5f","url":"https://daily.dev/sources/apievangelist"},"commentCount":1,"discussionUrl":"https://daily.dev/posts/standalone-api-documentation-generated-from-apis-json-s7anei9d4","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":20},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":1}],"keywords":"architecture,backend,openapi","timeRequired":"PT3M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"API Evangelist","item":"https://daily.dev/sources/apievangelist"},{"@type":"ListItem","position":3,"name":"Standalone API Documentation Generated From APIs.json"}]} {"@context":"https://schema.org","@type":"WebPage","@id":"https://daily.dev/posts/standalone-api-documentation-generated-from-apis-json-s7anei9d4","comment":[{"@type":"Comment","text":"The single self-contained HTML file approach is underrated.
