Show HN: Lockable – sync locks for distributed systems

4 years ago

Hi guys, creator of lockable here - the easiest way to think of lockable is as `flock` for when you don’t have a shared file system. You can use it to control concurrent access to resources or to ensure only a single instance of a process runs at any given time.

Your processes can acquire, refresh and release locks via simple HTTP requests, so it’s language/framework agnostic. E.g. with `curl`:

    $ curl https://lockable.dev/api/acquire/my-lock-name
    {
      "response": true //or false, if the lock wasn’t available
    }


    $ curl https://lockable.dev/api/release/my-lock-name

There’s also a Python client[0], which makes using the service a more pleasant experience.

Feel free to play around, the free tier is fully functional. Happy to hear any feedback you might have.
