Hi HN,
I&#x27;m building Identety, an open-source Identity Provider implementing OAuth 2.0 and OpenID Connect. After years of working with identity systems, I&#x27;ve found existing solutions are either too complex, expensive, or inflexible for modern development workflows.
The core functionality will be open source from day one, with a parallel cloud offering (identety.dev) for those who prefer managed hosting.Tech stack (in progress):
---- NestJS framework- PostgreSQL with Drizzle ORM- OpenAPI&#x2F;Swagger docsCore features (all open source):
---- Full OAuth2&#x2F;OIDC implementation- Support for SPA, server, and m2m clients- Role-based access control- Type-safe from DB to APIThe goal is to democratize access to enterprise-grade identity management. Whether self-hosted or cloud-hosted, organizations will have access to the same robust core features.Github: https:&#x2F;&#x2F;github.com&#x2F;identety

Identety - an open-source Identity Provider

Me and my buddy are currently struggling in finding a good term to describe our product: is it a micro-backend ? A Headless CMS ? A Backend-as-a-Service ? An API ?https:&#x2F;&#x2F;manifest.build&#x2F; is a really simple 1-file backend to power the API of small to medium websites, apps, directories and so on.We first presented it as &quot;A complete backend that fits into 1 YAML file&quot; and got some attention. However, it can be deceptive as it does not compare to &quot;real&quot; backend frameworks like Laravel, Django or NestJS. Nor does it compete with backend infrastructure products.Talking with Manifest users, we found out that many of them were using it as a Headless CMS, so we are currently presenting it as such. However even there we are not 100% satisfied as it differs from the &quot;rich content experience&quot; offered by products like Sanity or Hygraph.As a developer, how would you call Manifest ?

There’s so much hype about building SaaS in “1 hour” with CursorAI, GPT, Cloud, you name it.
I decided to try something more &quot;realistic&quot;: building a SaaS in 2 days. I grabbed my favorite tools like Cursor, ChatGPT, and a simple stack: NestJS + MongoDB + NuxtJS, and started my weekend challenge.Spoiler: 16 hours wasn&#x27;t enough. So, I extended it to 32 hours—and finally finished in 33 hours. Did I beat the challenge? Feels like a win to me.I built UniqMail, a simple tool for sending personalized cold emails with AI. It’s straightforward—create a project, upload your data, and let AI handle the personalization. Plus you can connect your provider for sending emails directly. And yes I implemented credentials encryption so your data is safe :-)No hype, no over-engineering. Just a clean, efficient tool that gets the job done.It’s live now, perfect for anyone in sales, HR, or marketing who sends a lot of emails.Curious to try? Feedback is more than welcome!Website: https:&#x2F;&#x2F;uniqmail.app

Sure!It&#x27;s QR-based, so customers create an account, load money onto their account, then show their QR code to vendors who scan it to charge their account. We also provide plastic cards (think: gift card) for people who don&#x27;t want to use their phone but we see 80%+ of people interact completely on their phone&#x2F;online. We have an app and website (same codebase, Quasar framework) and for in-person payment (entry, bar) we provide iPads with connected CC readers.My best advice is this: your hardest challenges will not be technical in nature. The hardest part is the equipment, dealing with customers, hand-holding the festival organizers. I don&#x27;t say any of that as some gross thing or bad thing, just reality. In fact, I think I&#x27;ve succeeded larged based on the in-person aspect (We travel to the event and are on-site for the event) and being the &quot;I have all the answers for your festival payments&quot;-person. Rolling with the punches is a huge part of it.The whole thing runs on AWS Lambda with a postgres DB from Neon.tech. I&#x27;ll be honest, it&#x27;s incredibly over-architected, the whole thing could run a a couple (or even 1) servers as a traditional NodeJS app without issue (and with less complexity) but I used this project as learning experience and a chance to try our some technology I was interested in. Lambda is incredibly cool and I think I might have one of the best use-cases for it (incredibly spikey load: no traffic for 9 mo, tiny traffic for presales for 1-2 months, 1 month with higher sales, then 1-2 days of the event with crazy sales) but the debugging story isn&#x27;t the best. SST makes it 10000x better than anything else I&#x27;ve tried and the developer experience is bar-none for writing lambdas but all the other crap (CloudFormation, logs, monitoring, etc) is so much overhead. If I was writing this again today I&#x27;d probably look at something like NestJS but I won&#x27;t let myself re-write the code (again) without a pressing reason and if I need to spend time anywhere it&#x27;s sales&#x2F;marketing.Here is my, crappy, &quot;marketing&quot; website: <a href="https:&#x2F;&#x2F;grubbux.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;grubbux.com&#x2F;</a>

## Description

Nest is a framework for building efficient, scalable [Node.js](http://nodejs.org) server-side applications. It uses modern JavaScript, is built with  [TypeScript](http://www.typescriptlang.org) preserves compatibility with pure JavaScript and combines elements of OOP (Object Oriented Programming), FP (Functional Programming), and FRP (Functional Reactive Programming).

Under the hood, Nest makes use of [Express](https://expressjs.com/), but also, provides compatibility with a wide range of other libraries, like e.g. [Fastify](https://github.com/fastify/fastify), allowing for easy use of the myriad third-party plugins which are available.

## Installation

```js
$ npm install
```

## Getting Started

Setting up a new project is quite simple. With npm installed, you can create a new Nest project with the following commands in your OS terminal:

```js
$ npm i -g @nestjs/cli
$ nest new project-name
```

## Running the app

```js
# development
$ npm run start

# watch mode
$ npm run start:dev

# production mode
$ npm run start:prod
```
