How I Launch A Postwoman v1.0 👽: Free, Fast & Beautiful Alternative To Postman 🎉

So, here’s how Postwoman 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!

How it all began

The initial tweet about the idea got 200+ likes and 50+ retweets so people were definitely interested in this kind of tool.
I literally launched Postwoman on a 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.
I was that guy.
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 Postwoman 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, was live 🎉
I actually wrapped up work at 4:30 AM because I just couldn’t go to sleep without finishing that one thing 😅

Apart from the project development, there were other goodies happened since v0.1.0:
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! 🎉
If you think Postwoman 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!

This kinda support is what makes open source community priceless

Do you have some un-common ways that you might want to share with our community? I mean what was done differently by you - that is not usually concidered as default paths? curious to see some insights

That’s a nice question. What came to my mind first was…
I always tried to limit my technical aids to minimum. That is: It’s a fact that I don’t have a laptop. I either code from my work space or from my friends PCs.

This makes me spend more time either in work space with my colleague or with my friends. It helped me to build a good network and friendship in my social life even as a developer. This is something most of us miss or give least priority.

Since I don’t have a laptop (I was very financially backward, which why I couldn’t even afford to buy a laptop) I never got a chance to work on a better system than my 7-year old PC. But this always helped me. I built Postwoman because my PC couldn’t afford to run another Electron app like Postman or any such apps. So, I was forced to make a lightweight, fast and better alternative. The same thing happened for my other projects such as Books, it was a Google Books clone. I made that because, Google Books site took around 2 mins to load (we’ve a poor internet connectivity). Books loads the home page in 2 seconds.

I would love to speak more on this. May be I’ll write an article on this. Who knows.
