Software gets abandoned all the time. A maintainer moves on, a startup shuts down, a vendor retires an API, a plugin stops getting updates. The code that depended on it doesn’t disappear. It keeps running in production, quietly piling up risk, until something breaks.
Cars have an aftermarket for exactly this situation. Once the original maker stops supplying parts, other suppliers step in. Aftermarket.dev brings that idea to software.
Compatible Replacements for Discontinued Software
The core product is a home for community-maintained replacements: forks of discontinued libraries, revived plugins, drop-in substitutes for old SaaS integrations. Each one is tracked, tested and kept alive by the people who still need it.
The sharpest angle is an aftermarket for APIs. When a service shuts down an endpoint, every client built against it breaks at once. A compatibility implementation that speaks the old API and maps it onto something current lets those clients keep working without a rewrite. Discontinued APIs are a constant in this industry, and nobody owns the business of keeping them alive. Yet.
Why .dev Fits
The .dev extension tells developers who the site is for before it even loads. Aftermarket is a familiar commercial word with a clear meaning: parts and service after the original sale. Put together, the name reads as a marketplace and maintenance hub for software’s second life, a startup concept that arrives with its brand already built.
