Curl.Md
Turn any URL into low-token markdown optimized for AI agents.
Curl.Md is a pragmatic, cost-saving tool for feeding web content into LLMs. Its free tier with generous limits, open-source code, and agent integrations make it a practical pick for developers. However, it's not a full scraper—skip it if you need rendered screenshots or heavy JavaScript handling. For most agent workflows, it's reliable and worth trying before paid alternatives.

About Curl.Md
Curl.Md converts any URL into clean, optimized markdown with minimal token usage, purpose-built for LLM context and AI agent workflows. Developers can start instantly by prefixing a URL with `curl.md/` in the browser, use the CLI via curl/npm/bun, or integrate programmatically through the REST API, SDK, and MCP server. Official plugins support agents like Amp, Claude, OpenCode, and Pi. The service is free with generous rate limits, and signing in raises those limits; prepaid credits remove rate limits entirely. Open source under MIT and hosted on GitHub, Curl.Md has already saved users over 5.7 billion tokens—equivalent to more than $17,000 in AI inference costs. It's a lightweight, token-efficient alternative to full-page scraping, ideal for feeding web content into LLMs without bloating context windows.
Behind the Verdict
Curl.Md earns its place in the AI agent toolkit by focusing on a single, well-defined job: converting web pages into markdown that minimizes token consumption. The service has already saved users over 5.7 billion tokens, translating to over $17,000 in AI inference costs—a tangible, measurable benefit for heavy LLM users. Strengths: The browser prefix (`curl.md/<url>`) is a zero-install entry point that any developer can try immediately. The CLI (via curl, npm, or bun) integrates into scripts and cron jobs for automated ingestion. The REST API, SDK, and MCP server provide programmatic access, and official plugins for Amp, Claude, OpenCode, and Pi cover the most popular coding agents. Being open source (MIT) means you can self-host or audit the code, and the token savings counter gives you a dashboard of value. Weaknesses: The tool is not a general-purpose web scraper—it does not render JavaScript-heavy SPAs fully, and it doesn't provide screenshots. For dynamic single-page applications that rely on client-side rendering, you may see incomplete content. There's also no dedicated support for enterprise teams, and the free tier's rate limits, while generous, could be restrictive for high-volume scraping without signing in or purchasing credits. Where it fits: Curl.Md shines for developers building AI agents that need web context—feeding documentation, blog posts, or internal pages directly into LLM prompts. It's also ideal for RAG pipelines where token efficiency reduces costs. Where it doesn't: If you need full page rendering, screenshots, or heavy JavaScript execution, look elsewhere. Curl.Md is not a replacement for tools like Puppeteer or Playwright for complex scraping tasks.

Real-world workflow fit
Concrete scenarios for the personas Curl.Md actually fits — and what changes day-one when you adopt it.
You're building a Claude agent that needs to read documentation from multiple sites. You install the official Curl.Md plugin for Claude, then use it to fetch and convert docs into low-token markdown, saving context window and reducing token costs.
Outcome: Claude gets clean, concise markdown without bloat, allowing it to process more pages within the context limit, and you save money on tokens.
You run a daily cron job that scrapes several industry blogs to feed into a RAG pipeline. You set up a bash script using the Curl.Md CLI to fetch each URL and pipe the markdown into your vector store.
Outcome: The pipeline ingests content consistently with minimal token usage, and you avoid the overhead of a full-scareper, reducing API costs.
You want to summarize a set of lengthy articles for a report. You use the browser prefix `curl.md/<url>` to quickly convert each article into markdown, then paste into ChatGPT for summarization.
Outcome: You save time copying and pasting, and the summarization is more efficient because the markdown is already stripped of web clutter.
Use Cases
- Feed web documentation into Claude or Cursor for code generation.
- Convert blog posts into markdown for LLM context windows.
- Automate daily web content ingestion into AI pipelines via CLI.
- Use as a preprocessing step in RAG workflows.
- Simplify web scraping for personal AI assistants with token budgets.
- Quickly fetch and summarize articles using agent plugins.
- Shape output with objectives and keywords for targeted analysis.
- Integrate with MCP server for advanced agent tool use.
Limitations
- Curl.md offers free anonymous usage with generous rate limits, while signed-in users get higher limits and prepaid credits can skip rate limits entirely.
- It is open source under the MIT License.
- The tool converts URLs into low-token markdown optimized for AI agents, but specific page rendering limitations are not detailed in the evidence.
- The tool may not fully render JavaScript-heavy single-page applications, potentially missing content that requires client-side execution.

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.
Curl.Md's free tier with generous rate limits suits individual developers and small teams. For higher limits or unlimited usage, prepaid credits are available at a cost, which may be more economical than subscription-based alternatives like Jina AI Reader or r.jina.ai for token-efficient conversion. Larger teams needing dedicated support may find better value in enterprise scrapers like Apify or ScrapingBee.
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.
For browser users, setup is instant—just prefix any URL with `curl.md/`. For CLI, installation via curl, npm, or bun takes minutes, and you can fetch your first URL immediately. Adding agent plugins varies: Claude, OpenCode, and Pi plugins install in seconds with a one-liner, while Cursor and Codex may require configuring the MCP server or skills, which takes a few extra minutes.
