Show HN: Callosum – A smarter OpenAPI editor/client

Hacker News - 14 min 10 sec ago

A couple years ago I was really frustrated by Postman, it couldn't do basic JSON schema validation, and didn't interoperate well with the OpenAPI spec I had to use for serverless deployments. On top of that, they started requiring an account and cloud sync, and other things I just wasn't comfortable with.

So what's an engineer to do? Build yet another API Client of course! [0] It's still fairly rough and crashes more often than I like, but it's basically at the point that I've switched most of my usage so I figured I would rip off the bandaid and do a Show HN.

Short list of some of the (IMHO) cool features that you can't do in Postman:

* Generate JSON Schema from request/response data.

* Generate request content template from JSON Schema.

* Reusable Schema components (Analyze->Extract Schemas menu)

* Basic field and JSON validation (so much more to do here!)

* Embeddable environment and encrypted variables [1] in the OpenAPI document.

* From scratch, run a MITM proxy and record API requests, then automatically generate an OpenAPI spec.

* Deep linking w/o a web server.

There's a short youtube playlist of some of these features, but I need to spend some time demoing the rest of them. What is most interesting to folks?

I would love to integrate better with the API doc generation tools but need to figure out how that would look. Speakeasy/Redocly/etc are some great projects and I don't want to reinvent the wheels there.

I would also seriously appreciate some tough love/feedback to make this even better. I'm sure someone smarter than me can pick apart the variable encryption (I broke rule #1 of cryptography and rolled my own, but I couldn't find a similar use case)

Show HN: A Platform to Explore Hackathons Around the World

Hacker News - 15 min 56 sec ago

I built a website which lists all hackathon posting from various other sources (currently Devpost and Unstop), on click it redirects to the original source.

Surprisingly, the APIs these websites used were open, which they used to populate their page with hackathons data.

So by spending maybe around 3 hours? This is the end result. It is built using Nextjs 15.

I tried to make it as best as I can, but hey, would love to hear any comments on improvements. There maybe some mistakes but yeah, I am here to learn.

Also, not the greatest of the UIs, but I wanted to get out the MVP, while most of my time was spent in normalizing the JSON from different hackathon website APIs.

I am looking to add more sources, eg. devpost, hackerearth, hack2skill, etc. I might need to scrape their data as their HTML is prepopulated when it is fetched, or have to find some other turnarounds.

Is there any tool built for CXOs so they can have access to the entire data?

Hacker News - 26 min 35 sec ago

CXOs and agents have completely different workflows, but they’re still using the same CRM/ticketing tools. Is there anything designed specifically for C-level executives?
