That makes sense, thanks @tmoberg ! We’ve gotten a feature request filed to support this, but I don’t think we’ll implement it soon since it is more “dynamic” of a header than our usual static ones and am not sure how we’ll create it within our current framework.
Nonetheless, we’ll let you know if we do implement it with a followup in this thread.
+1 to this — lack of scheduled functions is currently holding us back. AWS Lambda natively supports scheduled events, but unfortunately Netlify’s wrapper doesn’t expose that functionality.
Hi, @DavidChouinard, thank you for this +1. I’ve added this to the open feature request for being able to schedule Netlify Functions and we’ll follow-up here if/when that becomes available.
I’m also looking for the ability to schedule functions within Netlify, and not using an external service like Zapier.
My use-case is for running periodic tasks that are unrelated to user-input. For example, I want to send email reports to users based on times that they set (eg. send me an update at 10pm) so I’d want to periodically run the function to check if anything needs sending. Similarly, I’d want to be able to run functions on a regular basis for other things like periodically pulling data from external APIs.
Same here, I’m doing a POC and it looks like we’ll use Zapier or EasyCron to hit a Netlify function… would be nice to keep our codebase self-contained!
I need custom lambda runtime support. I want to keep using Netlify for the task I am using it but I am no longer using JS nor Go for my applications. Would be nice if Netlify would be more open (have it on docs) about state of support for custom lambda runtime. I’ve been wondering if it is supported or not. And I am still not sure.
+1 for custom runtimes. I find it crazy that whilst AWS Lambda supports a whole range of languages and runtimes, we are restricted to just Go and Nodejs. AWS provided the custom runtime functionality so users aren’t tied down to a set of languages. Why not make use of it Netlify?
Hi, @ejohnson, @superherointj, and @awprice. We’ve added these +1s for additional runtimes and scheduled function calls. Thanks for sharing your thoughts on adding these new features to Netlify.
The additional runtime I’m using is Reason/Ocaml.
Thanks for that detail, I’ve updated the feature request!
@luke Any traction on this feature request ?
Sorry @titusrobyk, but the answer is not yet. You’ll know if we implement one since we’ll follow up in this thread as promised 
I don’t foresee this happening anytime soon since the number of requests is quite small, so you’d be best off not waiting but finding some other way to run your other-language functions, though we will still follow up if the situation changes of course!
I’d love to see this as well. Being able to fire off a job every hour is pretty crucial for us.
totally. I have added your request to the issue.
I would love to see this feature as well, I hope it gets prioritized. I’ve collected emails from users using Netlify Forms and I want to send them weekly emails based on content files in my NetlifyCMS Nuxt site. Would love to be able to schedule a weekly cron job.
+1 for cron. Hope it will be released soon
+1 to the scheduling. It’s the one thing stopping me waving the JAMstack flag as the go-to; we do a lot of data-fetching from third parties (fetching records that have changed since the last fetch usually). Being able to trigger such a thing to then store the received data in FaunaDB would be an absolute dream. At the moment it’s a button I manually have to press; no use for triggering notifications based on changing data if the user has to log in to set that off!
I’ll also throw my hat in the ring in terms of requesting additional language support for functions, namely Ruby.
noted, @jaredwhite. I don’t have an eta, at all, but i have added your vote to the language support issue.
How about making httrack available as a build tool, so we could (for example) upload PHP files to GitHub and crawl those files with httrack to create the public website?
