Https://n8n.io/, https://github.com/huginn/huginn, https://automatisch.io/, https://www.activepieces.com/ and theres a lot more... I've used n8n, node-red, and huginn (a while back), but imo n8n has been the simplest off the shelf. - Source: Hacker News / 4 months ago

Don’t know the exact details of what it supports but I use Automatisch to send RSS feed updates to a channel on my Discord server. Might be worth looking into! Source: about 1 year ago

You can also monitor up to five webpages for free with VisualPing. Source: 12 months ago

As a belt and braces approach you could try using something like visualping.io (others are available) to monitor the URL https://recruitment.raf.mod.uk/apply/applying-for?c=15&r=293&type=regular and check when the wording "THIS ROLE IS CURRENTLY CLOSED FOR NEW APPLICATIONS. PLEASE REGISTER YOUR INTEREST AND WE WILL BE IN TOUCH WHEN IT REOPENS." disappears, and it will send you an email when it detects a change. Source: about 1 year ago
