Logo.dev turns a domain, stock ticker, ISIN, crypto symbol, or company name into that company’s logo or its brand profile. To show a logo in a website or app, use an image URL from the Logo.dev CDN. To get a logo file or brand data on your server, use the Logo.dev API.

​
How it works

​
Show a logo with a URL

Put an identifier in a CDN URL, and the company’s logo comes back as an image:
For most apps, that URL is the whole integration. Enter a domain to try it: The identifier can be a domain, a stock ticker, an ISIN, a crypto symbol, or a company name. Query parameters set the size, format, and theme. The URL takes a publishable key, which is safe in client code. By default, the URL returns an image for any identifier. If Logo.dev has no logo for the company, you get a monogram instead of a broken image. You can turn off that fallback and handle the miss yourself. When a company changes its logo, Logo.dev updates the image behind the same URL. You do not change your code. Caching explains when browsers show the new logo.

​
Get files and data on your server

Use the API when you need the file itself or data about the brand. Examples are a logo in a PDF, an email, or an OG image, a copy in your own storage, brand colors, or a company name resolved to a domain. The API takes a secret key that stays on your server. It returns a download URL for each file, so self-hosting starts there. Do not download images from the CDN to build your own copy. The CDN serves images for display, and fair use covers the limits.

​
Connect an AI agent

If an AI agent does the work, connect it to the Logo.dev MCP server. The server calls the API for the agent. You sign in with OAuth instead of pasting a secret key.
