{๐ŸŒฑ} About

Submit JSON helps web developers streamline the โ€œsubmissionโ€ half of form submissions. Itโ€™s also great at alerting you when a new user signs up, for example.

It notifies you via email, webhooks, and Slack, and it stays out of your way. The โ€œformโ€ half of the form submission is totally up to you.

{๐Ÿชฒ} The Problem

Letโ€™s face it, coding web forms can be a bit of a drag, but itโ€™s hard to avoid if your goal is a solid user experience. After putting in the effort to build a form, itโ€™s hard to find energy to wire up a submission notification, and good luck finding an elegant solution.

Handling one of these notifications is deceptively simple and way harder than it should be, and thatโ€™s where Submit JSON comes in to make your life easier.

{๐Ÿงช} The Solution

Submit JSONโ€™s API simplifies the entire process. Just POST your data to an endpoint, get notified in real time, and move on with your life.

To make things even easier, the JS client lets you submit data with one line of code after configuration. It works in modern browsers and various runtimes like Node.js, Bun, Deno, and Edge Runtime.

The best has yet to come, so stay tuned for more updates.

In the meantime I would love to hear your feedback and answer any questions you may have.

I hope that you find Submit JSON as useful as I do.

Possible disadvantages of CodePen

  • Performance Constraints
    Complex or resource-intensive projects may not perform as well on CodePen as they would in a full-fledged local development environment.
  • Subscription Costs
    While many features are free, advanced functionalities and additional storage options require a paid subscription, which may not be ideal for all users.
  • Limited Backend Capabilities
    CodePen is primarily designed for front-end development, so it offers limited support for backend technologies, making it less suitable for full-stack or server-side development.
  • Dependency Management
    Managing dependencies and libraries can be cumbersome compared to local development environments which have better tools for this purpose, like npm.

  • Occasional Performance Issues
    Some users have reported performance lags or slow processing times, particularly with larger JSON files.
