About FindUtils
Before you get started
How the tools work, where your data goes, and how to call them from code.
What is FindUtils?
FindUtils is an online toolbox with 436 tools for development, design, documents, calculations, and everyday tasks. Guides and cheatsheets help you use them.
Do I need an account?
Core browser tools do not require an account. Some separate services have their own access requirements. Check the tool or service page before you start.
Where does my data go?
Many tools process input in your browser. Some tools send requests to a service, such as network lookups or AI features. Check the page instructions before you enter sensitive data. Pages can load analytics and ads.
Can I use tools through an API or an AI assistant?
Yes. The REST API provides 365 tools. The MCP server provides 365 tools for compatible AI clients. Their reference pages explain the inputs and available operations.
When should I use the API instead of the page?
Use the API when the job is a single self-contained transform you want done from a script or an agent: formatting or validating JSON, encoding and hashing, converting a document, generating UUIDs or a PDF invoice, or running a calculation. Use the page when the tool needs a local file, the camera, or a canvas — those run only in the browser.
What are the limits, and is there a key?
There is no account and no API key. Requests are rate limited per IP address, and every response carries the standard RateLimit headers so a client can pace itself. Nothing you send is stored for later retrieval: a call returns its result, and there is no read-back endpoint.
Is there a machine-readable index of the site?
Yes. llms.txt is the index, with a per-section file for each category; llms-full.txt is the complete reference. The OpenAPI 3.1 spec describes every REST endpoint. Every page listed in the sitemaps has a Markdown twin — tool pages, category hubs, guides, cheatsheets, blog posts, API and MCP reference pages, and site pages such as About and Privacy — except the live Discover directory: append markdown.md to the path, add the .md suffix, or send an Accept: text/markdown header.
Is this the GNU findutils project?
No. FindUtils.com is a separate website for online utilities. GNU findutils provides command-line programs such as find, locate, and xargs.
