What HN said

What people liked

  • Clean documentation and styling

    From 3 comments
    • Very cool. And kudos on the clean documentation.
      brikis98 on HN
    • Great site, simple and gets the product across well. It might be nice to have some examples of what the service could be used for, why it is/will be better than setting up cron…

    • I agree. Nicely styled, easy to read, and a great, well thought out API structure. If I was looking to hire, this entire project would shout HIRE HIM!

  • Useful for hosted apps and shared hosting without cron access

    From 3 comments
    • Yes! I currently have a server ran specifically for managing my cron tasks, I would love to outsource it to a reliable company. If you could guarantee reliability then I'd love…

    • This would be great, there are services like Heroku that provide nearly "free hosting" but have horrible cron job support unless you pay like 10 bucks a month for it. Be nice to…

    • I've used web-based cron services in the past for projects on shared hosting that doesn't offer decent cron support. This would've been a godsend; most are downright terrible or…

Objections

  • Techies can edit crontab easily; little added value

    From 1 comment
    • For most people, the URLs these jobs are hitting will be calling code that they themselves have written, is that right? If so, since I'm writing a bunch of code to do work, the…

  • Security concern: password sent over HTTP

    From 2 comments
    • Yeah, I cringed when I saw the password-over-http part. Fine for a free service, not for paid.

    • If cron.io is made into a paid service, i would suggest using HTTPS for the API.

  • Abuse and DoS risk from fast cron requests

    From 1 comment
    • Do tell me you are checking robots.txt then. This has a great potential for DoS, email confirmations or not.

Requests

  • HTTPS for the API

    From 2 comments
    • If cron.io is made into a paid service, i would suggest using HTTPS for the API.
      sharken on HN
    • Given the documented auth mechanism, I'd say this is a requirement.

  • Retry failed calls

    From 2 comments
    • Definitely a good idea! The only thing that would make me hesitant to use this service is that you are at the mercy of any kind of network outages between your servers and mine.…

    • One thing I love about Mailgun is that they keep retrying POSTs to our URL if it doesn't respond with a 200 status code. It adds a nice level of reliability to our email…

  • Failure notifications

    From 2 comments
    • Suggestion: Add a notify-on-failure attribute to cron jobs. If cron fails, notify via email or SMS.
      toomuchtodo on HN
    • Consider this feature which I've thought about building myself at times. With the cron request a token/guid/hash can be passed along with the job which is unique to the request.…

  • Flexible schedule formats

    From 1 comment
    • What I'd expect from this modern service to offer alternative cron period formats e.g: every 24 min, every hour, every other tuesday 3pm.

Questions

  • Should it be a paid full service and what pricing is reasonable

    From 4 comments
    • I think I'd pay for the convenience and reliability, but I hope you'd have a small pricing option. I'd use <5 jobs at any one time, and probably wouldn't want to pay more than…
      chad_oliver on HN
    • I would pay for this provided it was reliable and relatively cheap. $1/cron, for e.g.
      paulitex on HN
    • I would pay $0.10 per X cron requests (a la AWS pricing). $1/cron? Above $10-20/month, I'd just write it myself.
      toomuchtodo on HN
    • I think you could arguably charge based on frequency. Weekly job -> free. Daily job -> 10c a month, Hourly 50c a month, more than that, pick a price. Definitely useful but then…

Alternatives named

  • webcron.org

    From 1 comment
    • I've been using webcron.org for a few projects, works well enough, but my most important criteria is price for something this simple. It's really cheap, $0.00014 per request.

  • Torpedo (GitHub HTTP callback scheduler)

    From 1 comment
    • I released a similar project on Github called Torpedo. It lets you schedule HTTP callbacks via a REST API. ``` curl -X POST http://127.0.0.1:7931/api/callbacks/ \ -d…

  • CloudQuartz

    From 1 comment
    • We released a web based cron with RESTful API and web UI recently called CloudQuartz. You can find it at http://www.thecloudblocks.com

  • webbasedcron.com

    From 1 comment
    • Yes it should be a full service. I particularly hate the existing web cron services, like webbasedcron.com and others. They're poorly designed, poorly run, and poorly supported.…
