brokenlink.io is simple and fast broken links checker API.
Use it for free and know how links on a website are resolved and why. Links availability has a big impact on SEO, specially when positioning of a website depends on customers’ CMS content.
Integrate it in your CI system and validate your links from a programmable perspective.
Launched on the 2nd November 2017.
What the API addressed
A link can fail after an article or page is published, even if it worked when someone wrote it. Sites with content managed by many people are especially exposed to that problem. brokenlink.io offered a way to check link destinations programmatically, so the result could be used in a publishing or continuous integration workflow.
The product page above is an archive of the 2017 launch. The included screenshot shows the original positioning and pricing; it should be read as historical material, not a current offer. The projects index contains other software experiments, and the articles index collects my longer writing on engineering and products.
A publishing workflow
The API was meant to answer a small but recurring question before a page went live: do the links in this content resolve as expected? An editor could inspect a single URL, while a development team could call the service from a continuous integration job and make link checks part of a repeatable publishing process. That is useful when a site depends on articles submitted through a content management system, where a broken reference can escape notice.
The Product Hunt link and screenshot document the launch period. They are not a promise about present-day pricing, support or availability. For another browser-related experiment from the same era, see the Hacker News notifier. The projects archive contains the wider sequence of products and prototypes.
