Launching Hoppscotch v1.0 πŸ‘½ - free, fast & beautiful API request builder πŸŽ‰

So, here’s how Hoppscotch happened.

You know the drill. You’re developing an app for a client and you need to test every APIs and every APIs response in every method, on every requests.

Our team was already using Postman to test all the variations of an API, but my 7 year old PC couldn't afford to run another Electron app just to see the request responses in all of them. And that’s how it all started.

How about making a tool where you can test your APIs from your browser itself without switching between apps as you work? That would be neat, huh!

πŸ‘½ A free, fast and beautiful API request builder used by 75k+ developers. https://hoppscotch.io

How it all began

The initial tweet about the idea got 250+ likes and 60+ retweets so people were definitely interested in this kind of tool.

I literally launched Hoppscotch on a dev.to article and wrote about it on Hacker News, HackerNoon, Medium, HashNode, Reddit, Twitter etc.

I saw a guy writing JavaScript today.
No frameworks.
No libraries.
No problems.
He just did it.
Writing JavaScript.
Like a Psychopath.

It was me πŸ™ƒ

I had some problems with CORS in deployment, but I found a quick workaround. I used Vue.js and apparently migrated to Nuxt.js.

At that point I started thinking that the tool can actually be published as a standalone web app, and the WebSocket testing feature can just be an addition. So I shifted my goal and starting working towards that.

I added few themes, polished up the UI a bit, struggled for 30 mins to come up with a name and..... drumroll Hoppscotch it is. I setup a GitHub repo for people who were interested to contribute.

After I open sourced the code, polished up the UI, and finished bunch of other smaller things, hoppscotch.io was live πŸŽ‰

I actually wrapped up work at 4:30 AM because I just couldn’t go to sleep without finishing that one thing πŸ˜…

Apart from the project development, there were other goodies happened since initial release:

I was solving my own problem with the hope that I'll also gonna solve other people’s problems. The most important thing about is that in the end, you get a lot of amazing and positive feedback, which is basically the only thing that drives you to do better and more awesome work! πŸŽ‰

If you think Hoppscotch is worthy of existing as a free, fast alternative to Postman, please consider giving us a confidence boost! Star the repo on GitHub, Tweet, share among your friends, teams and contacts!

Insomnia is the best such tool I've used - insomnia.rest


Postwoman is an online web app. No need to install or update build, because of this, there's no other overhead to system for using a testing tool. Moreover apps such as Postman and insomnia are built with electron which consumes a considerable amount of resources of the system.


Postwoman have multi platform, multi device support. API testing can be done even from your smartphone now.


but why would you do it from a smartphone? the other clients are multi platform too...

If you need to start debugging your Rest from mobile is really useful. Online version can avoid instalation same software for all devs in your team and be easy updated with new collection, easy maintenance in different environments

Well said! πŸ”₯πŸ‘


Fantastic! The UI looks very good. It would be awesome if you add WebSocket support.
And a light theme would be useful as well. Some people like me having trouble with using dark mode in UI. I have some kind of problem with my eyes and UIs looks blurry in dark mode :-(

UPD: Sorry didn't find customization screen before :-)


Hi there,

Postwoman does indeed feature WebSocket support, you can select it on the sidebar (a little cloud icon).

Have fun!!


WebSocket support is already landed from v0.1.0 πŸŽ‰



It looks very good and promising. But I have readability problem of a response object when a light theme is activated. Yellow values on white background are barely seen, have to highlight text to see it. See attached picture.
P.S It looks like I am going to delete Postman from my machine. :)



I just pushed a quick fix for readability problem on light-themes.
Just do a hard refresh Ctrl + Shift + r to update to the latest version and boom! issues is fixed πŸ”₯

(if issues persists, clear cookies and refresh)


Now I even without glasses can read it :) Thanks :)


I'm obsessed with dark theme which why i concentrated on dark themes first. But now I'll work more on theme white mode. Thanks for pinging this. Next priority is light theme. If you'd like to suggest a theme pallet for light theme, shoot a DM, or perhaps a PR? 😌


This is a cool project! Well done! Just one thing though. It is quite difficult to take anyone serious using so many emoji's, especially a developer, especially in github commit messages. Besides my 2 cents, this seems like a fun alternative to postman


I don't think usage of emojis in commit messages limit the project's seriousness. Gitmoji (gitmoji.carloscuesta.me) is a highly appreciated project on GitHub supported by a huge community of devs πŸ€”


Is there a suppor for environments? That would be awesome! :)


Pre-request scripts and Environment variables are deployed to production but experimental!
Full list of feature are here: github.com/liyasthomas/postwoman


  1. Open Pre-request scripts by clicking the "<>" icon button under request Method

  2. Set env variables with JavaScript notation: pw.environment.set("key", "value"); inside pre-request script textarea.

Ex: pw.environment.set("route", "/api/users");

  1. Use <<key>> (including double angle brackets) anywhere inside request section as an env var

Ex: <<route>> inside Path field




Other use cases are:

  • Including the timestamp in the request headers
  • Sending a random alphanumeric string in the URL parameters
  • You can even chain requests in near future πŸ”₯

Full information can be found here: github.com/liyasthomas/postwoman/p...


cool. thanks for your work!

I'm thinking of something like environment in postman where you can easily change variables without modifying the request.

Actually this is cooking up! and will be deployed soon.

wow. will be looking forward to this feature. You're awesome! :)

Glad you liked it! Star the project on GitHub, share among your friends/teams πŸ™πŸ‘½πŸ›Έβœ¨


This looks interesting. Is the best way to develop with localhost to use Ngrok? Or is there something that I am missing?


localhost endpoints can be tested by installing a middleware browser extension. Links are in repo's readme.


Congratulations on 1.0! The UI looks fantastic. I look forward to giving this a try πŸ˜ƒ


Glad you liked it! πŸ’œ
Looking forward on how Postwoman could ease up your development! Do share among your friends/team ⚑


"I was that guy."

Funny, I always assumed you were a girl...unless you're using "guy" in the gender-agnostic form ;)


Yeah! I've heard this many times before.


I had some problems with CORS in deployment, but I found a quick workaround.

i have been following postwomen since the DEV post. How did you fix it ?


We implemented Proxy mode. For requests having CORS issues, go to Settings > Turn on Proxy
That's it. But you don't want to do this at first. We'll prompt you to enable proxy only if the requests requires it. πŸ‘½βœ¨


Congrats! I was briefly observing Postwoman when it was first published but didn't feel the urge to switch from Postman. Now then, the 1.0 feature list demands me to give it another spin.


You should look at our roadmap and stuffs we pipelined for future πŸ”₯πŸ‘½πŸ›Έ


Great to finally meet the man behind the legend!




Seems an awesome project, I going to try it out! Btw, Good Article Liyas ! πŸ¦„


I shared Postwoman on LinkedIn, glad to see that you're launching it!


Thanks. Let the world know Postwoman exists.


Hey Liyas,

You know, it was much needed. Thanks for giving us a great app. Will be grateful and I will try to contribute to the project as well.


Thats awesome! πŸ™ŒπŸΌ


Nice! It seems to have come a long way since i initially checked it out back when you first posted it!


Yes, there's been 650 commits since v0.1.0 πŸŽ‰


Curious - do you have any concerns around storing potentially sensitive information in local storage? My understanding is that any app can view what is in local storage.


Postwoman is a 100% client side application. PW just works even if you download the entire web page to system and opened from there, there's no client-server data transfer ever happening, except on Proxy mode, which is optional.

We uses localStorage for storing the History entries and the current state of request section. We stay compliant on Same origin policy throughout our implementation. Moreover, there's always an option to Clear/Disallow cookies.

When I first started working PW, I never wanted to have a Sign-up flow because it somehow seemed to decrease my testing flow. But as the project gained such traction & grew tremendously, having a Sign-in with GitHub/Google and storing data on a GitHub repo is pipelined for future with prime priority.

did you really had to plagiarize the original name of postman? couldn't you come up with something new and original?
