Source: https://agentreadyhtml.com/llms-txt-index/fastht-ml-docs/ Site: Agent Ready HTML Last reviewed: 2026-11-05 # fastht.ml llms.txt In short fastht.ml serves a 4.7 KB llms.txt with 4 H2 sections and 21 links, graded B on the llmstxt.org structure (5 of 6 checks). It lacks same-site links. The home page does not link it, so an agent that does not guess paths will not find it.

The `FastHTML` class itself inherits from `Starlette`, and adds decorator-based routing with many additions, Beforeware, automatic `FT` to HTML rendering, and much more. Things to remember when writing FastHTML apps: - Although parts of its API are inspired by FastAPI, it is *not* compatible with FastAPI syntax and is not targeted at creating API services - FastHTML includes support for Pico CSS and the fastlite sqlite library, although using both are optional; sqlalchemy can be used directly or via the fastsql library, and any CSS framework can be used. Support for the Surreal and css-scope-inline libraries are also included, but both are optional - FastHTML is compatible with JS-native web components and any vanilla JS library, but not with React, Vue, or Svelte - Use `serve()` for running uvicorn (`if __name__ == "__main__"` is not needed since it's automatic) - When a title is needed with a response, use `Titled`; note that that already wraps children in `Container`, and already includes both the meta title as well as the H1 element. ## Docs - [FastHTML concise guide](https://www.fastht.ml/docs/ref/concise_guide.html.md): A brief overview of idiomatic FastHTML apps - [HTMX reference](https://raw.githubusercontent.com/bigskysoftware/htmx/master/www/content/reference.md): Brief description of all HTMX attributes, CSS classes, headers, events, extensions, js lib methods, and config options - [Starlette quick guide](https://gist.githubusercontent.com/jph00/e91192e9bdc1640f5421ce3c904f2efb/raw/61a2774912414029edaf1a55b506f0e283b93c46/starlette-quick.md): A quick overview of some Starlette features useful to FastHTML devs. ## API - [API List](https://www.fastht.ml/docs/apilist.txt): A succint list of all functions and methods in fasthtml. - [MonsterUI API List](https://raw.githubusercontent.com/AnswerDotAI/MonsterUI/refs/heads/main/docs/apilist.txt): Complete API Reference for Monster UI, a component framework similar to shadcn, but for FastHTML ## Examples - [Websockets application](https://raw.githubusercontent.com/AnswerDotAI/fasthtml/main/examples/basic_ws.py): Very brief example of using websockets with HTMX and FastHTML - [Todo list application](https://raw.githubusercontent.com/AnswerDotAI/fasthtml/main/examples/adv_app.py): Detailed walk-thru of a complete CRUD app in FastHTML showing idiomatic use of FastHTML and HTMX patterns. ## Optional - [Surreal](https://raw.githubusercontent.com/AnswerDotAI/surreal/main/README.md): Tiny jQuery alternative for plain Javascript with inline Locality of Behavior, providing `me` and `any` functions - [Starlette full documentation](https://gist.githubusercontent.com/jph00/809e4a4808d4510be0e3dc9565e9cbd3/raw/9b717589ca44cedc8aaf00b2b8cacef922964c0f/starlette-sml.md): A subset of the Starlette documentation useful for FastHTML development. - [JS App Walkthrough](https://www.fastht.ml/docs/tutorials/e2e.html.md): An end-to-end walkthrough of a complete FastHTML app, including deployment to railway. - [FastHTML by Example](https://www.fastht.ml/docs/tutorials/by_example.html.md): A collection of 4 FastHTML apps showcasing idiomatic use of FastHTML and HTMX patterns. - [Using Jupyter to write FastHTML](https://www.fastht.ml/docs/tutorials/jupyter_and_fasthtml.html.md): A guide to developing FastHTML apps inside Jupyter notebooks. - [FT Components](https://www.fastht.ml/docs/explains/explaining_xt_components.html.md): Explanation of the `FT` components, which are a way to write HTML in a Pythonic way. - [FAQ](https://www.fastht.ml/docs/explains/faq.html.md): Answers to common questions about FastHTML. - [MiniDataAPI Spec](https://www.fastht.ml/docs/explains/minidataapi.html.md): Explanation of the MiniDataAPI specification, which allows us to use the same API for many different database engines. - [OAuth](https://www.fastht.ml/docs/explains/oauth.html.md): Tutorial and explanation of how to use OAuth in FastHTML apps. - [Routes](https://www.fastht.ml/docs/explains/routes.html.md): Explanation of how routes work in FastHTML. - [WebSockets](https://www.fastht.ml/docs/explains/websockets.html.md): Explanation of websockets and how they work in FastHTML. - [Custom Components](https://www.fastht.ml/docs/ref/defining_xt_component.md): Explanation of how to create custom components in FastHTML. - [Handling Handlers](https://www.fastht.ml/docs/ref/handlers.html.md): Explanation of how to request and response handlers work in FastHTML as routes. - [Live Reloading](https://www.fastht.ml/docs/ref/live_reload.html.md): Explanation of how to use live reloading for FastHTML development. ``` First 45 of 46 lines. **Parse** graded B, 5 of 6 file: https://fastht.ml/docs/llms.txt FastHTML FastHTML is a python library which brings together Starlette, Uvicorn, HTMX, and fastcore's \`FT\` "FastTags" into a library for creating server-rendered hypermedia applications.

Ora's cached score: 42, grade D, scanned 4 September 2026. ## The parse fastht.ml lists 21 links: 14 point at fastht.ml or a relative path, 7 point elsewhere. The hosts it links most: fastht.ml (14), raw.githubusercontent.com (5), gist.githubusercontent.com (2). | H2 section | Links | | --- | --- | | Docs | 3 | | API | 2 | | Examples | 2 | | Optional | 14 | ## Grade against the llmstxt.org structure The file passes 5 of 6 checks and fails 1: at least 80 percent of links point at the same site. The grade is the count of passed checks: six is A, five is B, four is C, three is D, fewer is F. It measures structure only. Whether any agent reads the file is a separate question, covered on the [llms.txt reference](https://agentreadyhtml.com/llms-txt/). | Check | Result | Detail | | --- | --- | --- | | Starts with an H1 naming the site or project | Pass | H1: FastHTML | | Has a blockquote summary under the H1 | Pass | Blockquote summary found. | | Has at least one H2 section that lists links | Pass | 4 H2 sections, 4 with links. | | At least 80 percent of links point at the same site | Fail | 14 of 21 links stay on fastht.ml (67 percent). | | Under 100 KB | Pass | 4796 bytes as served. | | Plain markdown, no HTML | Pass | No HTML document markers in the body. | ## Ora's cached score Ora's cached report for fastht.ml gives it **42 of 100, grade D**, scanned on 4 September 2026. Its Access layer, which holds the read-layer checks below, scored 25 of 53 check points. Read from GET ora.ai/api/score/fastht.ml on 5 November 2026. The score is Ora's, not this site's, and the structure grade above is a different measure: it grades the llms.txt file against the llmstxt.org proposal, while Ora's score covers the whole site.

Ora's lab found (2026-10-19) that 86 percent of llms.txt fetches by agents arrived through a link, so an unlinked file is mostly a file nobody opens. ## How it compares At 4.7 KB the file is larger than 31 percent of the 2,529 plain-text llms.txt files in this edition, and its 21 links put it ahead of 34 percent of them on link count. The home page declares no generator. Size bucket: 2 to 10 KB. Curated example. Category: Framework. Why it is in the index: One of the earliest llms.txt files, from the proposal author's own framework. Owner as listed: FastHTML (Answer.AI).
