Curl.Md
Curl.Md turns any URL into low-token markdown for LLM context and agent workflows.
Curl.Md does one narrow job and does it cheaply: URL in, markdown out, at a token count your context window can afford. The prefix trick means zero setup for a quick pull, and the MCP server plus published plugins mean your coding agent connects without glue code. Skip it if you need rendered pages or screenshots — that is a browser-rendering scraper's job, not this one.

Skip Curl.Md if you need screenshots or layout-accurate rendering of a JavaScript-heavy SPA, since this is a fetch-to-markdown step rather than a browser-rendering scraper.
Anonymous use is capped by rate limits, so a high-volume background job will need you to sign in with GitHub or buy prepaid credits to keep fetching.
The entry point is free with generous rate limits, which fits solo developers and small teams testing a fetch-to-markdown step before committing budget. Signing in with GitHub raises those limits at no stated cost, and prepaid credits exist to skip rate limits for heavier ingestion. That puts it well below browser-rendering scraping stacks on cost for text-only extraction, but teams needing SLA-backed crawling coverage should budget for a rendering platform instead.

About Curl.Md
Curl.Md is a fetch-to-markdown converter built for AI agent context. Give it a URL and it returns distilled body content — not nav bars, scripts and boilerplate — so you spend tokens on the page, not the chrome around it. For anyone piping live web content into a model, that difference shows up directly on the bill. There are three ways in. In the browser, prefix any URL with curl.md/ and get markdown back. In the terminal, run curl curl.md/<url>, or install the CLI with curl, npm, or bun. In production, call the REST API and SDK from your own pipeline. Objectives and keywords let you steer what the converter keeps, which matters when you are pulling one docs page to answer one question rather than archiving a site. Agent support is the part most tools skip. Curl.Md ships an MCP server and a skills system, with official plugins published for Amp, Claude, OpenCode, and Pi. Codex, Cursor and other agents connect via skills, the CLI/MCP server, or a custom integration described in the Plugins Guide. The project is open source on GitHub under the MIT License. The homepage counter reported 5,714,681,303 tokens saved and $17,144.04 in avoided inference costs at the time of writing. Pricing is free with generous rate limits, higher once you sign in with GitHub, and prepaid credits skip rate limits entirely. This is a lightweight URL-to-markdown step, not a crawling platform — pick it for documentation, articles and text-heavy reference pages, and look elsewhere when you need screenshots or a JavaScript-heavy SPA resolved after render.
Behind the Verdict
The pitch here is simple enough to be believable: most web pages are mostly furniture, and you are paying per token for the furniture. Curl.Md strips it. We'd reach for this the moment a prompt starts with "here is the docs page" and the docs page is 40,000 tokens of sidebar links. Pick it when your input is text-heavy and stable — API references, changelogs, long-form articles, README files on GitHub. The objectives and keywords flags are the underrated part. Telling the converter what you're after beats dumping a page and hoping the model finds the paragraph. Pick it harder if you run coding agents. Official plugins for Amp, Claude, OpenCode and Pi, plus an MCP server and a skills system, mean the integration is already written. Codex and Cursor route through skills or the CLI rather than a first-party plugin, which is a slightly longer path but documented. Pass on it when the content only exists after JavaScript runs. A client-rendered SPA that populates on load will hand you an empty shell, and there is no browser rendering here to fix that. Screenshots and PDFs are also out of scope. Pass too if you need contractual guarantees. This is MIT-licensed open source with free rate limits, sign-in for higher ones, and prepaid credits to skip limits. That is a fine deal for a preprocessing step; it is not a vendor relationship with an SLA attached. The closest alternative is a general scraping API that bundles rendering and proxies. Those cost more per call and give you more machinery than a markdown fetch needs. In practice, we'd keep Curl.Md for the fast path and reach for a rendering scraper only for the pages Curl.Md cannot see. One caveat worth naming: the token and dollar counters on the homepage are self-reported. Useful as a signal of adoption, not as an

Real-world workflow fit
Concrete scenarios for the personas Curl.Md actually fits — and what changes day-one when you adopt it.
You install the CLI via npm, then prefix the docs URL you are working from with curl.md/ to get markdown straight into your prompt.
Outcome: The page arrives without nav bars or scripts, so more of your context window goes to the actual documentation.
You call the REST API from your ingestion job and pass objectives and keywords so the converter keeps the sections relevant to each downstream task.
Outcome: Ingestion returns smaller, task-focused markdown that costs fewer tokens per prompt than raw HTML.
You connect the MCP server to Codex or another agent, or follow the Plugins Guide to add an integration for a tool that has no official plugin.
Outcome: The agent can fetch a live web page as markdown as a tool call instead of you hand-feeding URLs.
Use Cases
- Feed web documentation into Claude or Cursor for code generation.
- Convert blog posts and articles into markdown for LLM context windows.
- Automate daily web content ingestion into AI pipelines via the CLI.
- Use as a preprocessing step in RAG workflows where text cleanliness beats layout fidelity.
- Give personal AI assistants web context without blowing the token budget.
- Fetch and summarize articles through agent plugins.
- Shape fetched output with objectives and keywords for targeted analysis.
- Expose web fetching to an agent through the MCP server.
Limitations
- curl.md is a URL-to-markdown conversion tool for agent context, offered free with rate limits; higher limits require signing in or prepaid credits.
- The documentation reviewed does not describe rendered-page fidelity or a JavaScript rendering layer, so SPAs that only populate after client-side execution are outside what the sources claim.
- Official integrations are documented for Amp, Claude, OpenAI Codex, Cursor, OpenCode, and Pi, while other agents use skills, the CLI/MCP server, or a custom integration built from the Plugins Guide.
- The sources reviewed do not document an SLA, dedicated support, or page-rendering guarantees.

Where the pricing makes sense
The company stage and team size where Curl.Md's pricing actually pencils out — and where peers do it cheaper.
The entry point is free with generous rate limits, which fits solo developers and small teams testing a fetch-to-markdown step before committing budget. Signing in with GitHub raises those limits at no stated cost, and prepaid credits exist to skip rate limits for heavier ingestion. That puts it well below browser-rendering scraping stacks on cost for text-only extraction, but teams needing SLA-backed crawling coverage should budget for a rendering platform instead.
Setup time & first value
How long it actually takes to get something useful out of Curl.Md — broken out by persona, not the marketing-page minute.
Browser users get first output in seconds by prefixing a URL with curl.md/. Terminal users installing the CLI via curl, npm, or bun are usually fetching within a few minutes. Wiring the REST API or MCP server into an existing agent pipeline depends on your stack, but the Plugins Guide covers Amp, Claude, Codex, Cursor, OpenCode, and Pi directly.
Switching to or from Curl.Md
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From manual copy-paste of page text into a prompt: swap in the curl.md/ prefix so the converter strips boilerplate for you instead.
- →From a raw HTML fetch in your pipeline: point the same request at curl.md and drop the HTML-to-text cleanup step.
- →From a heavier browser-scraping stack used only for text extraction: keep curl.md for docs and articles and reserve the rendering tool for pages that actually need it.
- →From a custom per-agent web fetch integration: use the MCP server or skills system so Codex, Cursor and other agents connect without bespoke code.
- ↗To a browser-rendering scraper such as Firecrawl or ScrapingBee: if you start needing screenshots or post-render extraction, that class of tool is the replacement.
- ↗To a full crawling platform: if you need site-wide crawling and scheduling rather than single-URL conversion, move the ingestion layer up a level.
- ↗To a self-hosted HTML-to-markdown library: since curl.md is MIT-licensed on GitHub, you can fork the approach into your own pipeline if you need it fully in-house.
