title: Heroku Scheduler vs Heroku Temporize Scheduler, what's the difference?
body: <p>I'm wondering what is the difference between the <a href="https://elements.heroku.com/addons/scheduler" rel="nofollow noreferrer">Heroku Scheduler</a> add-on and the <a href="https://elements.heroku.com/addons/temporize" rel="nofollow noreferrer">Heroku Temporize Scheduler</a> add-on.  They both seem to be free and do scheduled jobs.</p>
  
  <p>And how do they both compare to running a <a href="https://stackoverflow.com/a/474543/4825465">Python sched</a> in Heroku?</p>
  
  <p>I would like to run just one cron job to scrape some websites every minute with Heroku Python saving to Postgres. (I'm also trying to figure out what to write in a cron job to do so, but that's another question.)</p>

  <p>Update with the solution:</p>
  
  <p><strong>Thanks to danneu's suggestions, the working solution was using the Heroku Scheduler. It was super simple to set up thanks to <a href="http://guidovanoorschot.nl/adding-cron-jobs-to-a-django-project-with-heroku-scheduler/" rel="nofollow noreferrer">this tutorial</a>.</strong></p>
  
  <p>(I tried using sched and twisted, but both times I got:</p>

  <p>This was possibly due to my lack of experience of putting them in the correct place. It didn't work with a sync worker Heroku guricorn. I don't know the details.)</p>
