Like many founders, I thought the hardest part of building a startup would be writing the code.

It wasn't.

Hey PH!

I'm an independent developer and software engineer from China. I spend most of my time working with Python, APIs, and trying to turn messy problems into clean solutions.

I built three Chrome extensions in my spare time each one born from a real need I ran into during work or daily life. Thought I'd share them here. Hope they're useful to some of you too.

If you're new to this or the title sounds exaggerated to you; I'd like to invite you to open the App Store and search calorie tracker.
You'd find the same app. Over. And over. And over. We have now hundreds of calorie apps.
Just a different icon, slightly different colors but the same exact app uninspired clone at the core.
Don't get me wrong calorie tracking itself isn t the enemy but rather the flood the App Store and Social Media are drowning in.

Let me ask you:

Are relationships with food better?

Are users less confused?
Are people healthier?

Hi Product Hunt!

I m building Gold Dashboard at TR-MATE Global, a research-first interface for exploring XAUUSD price data, multi-timeframe charts, gold news, observed support and resistance levels, and market context.

Hola, Soy Joan un carpintero de familia carpintera. De aqu viene la idea de Cola de Milano, ya que todo carpintero conoce cola de milano. Llevo viendo a os la desorganizaci n de las carpinter as. Y quise aportar mi granito en ayudar nuestro gremio ayudando a todos los carpinteros para que puedan organizarse f cilmente y de forma intuitiva ayudando la firma de presupuestos y proyectos online y a adiendo las nuevas tecnolog as para leer facturas, renders, etc. La demo ya esta en varias carpinter as, estoy esperando el feedback con mucha ilusi n y seguir construyendo el proyecto y mejorarlo. Estoy abierto a que todos los carpinteros la puedan probar, la app esta en dos idiomas espa ol y ingles.

Alguien m s viene de un oficio manual y se ha lanzado a construir su propia herramienta? Me encantar a saber qu obst culos os encontrasteis por el camino y opiniones sobre colademilano.com

I m an indie developer too. AI helps me code, debug, research, and turn ideas into products but the token bills often grow long before a project earns anything.

I ve seen individual developers turn small side projects into real businesses and achieve things that once seemed impossible. I built Mustham API because I don t want promising ideas to be abandoned simply because using AI became too expensive.

Mustham API provides access to GPT, Claude, Gemini, and Grok through one platform. By combining capacity from different accounts and routes, many routes are priced at less than half of the corresponding official API price, while users can still choose the specific model and route they want.

I have already invested a significant amount in capacity and stability testing, and the platform is still costing me more than it earns. We also provide direct support if you encounter stability, integration, or usage problems, we will help investigate them as quickly as possible.

Candor is my free, MIT-licensed Claude Code plugin: twelve work-mode "personas" that make an AI assistant direct, verification-driven, and honest instead of agreeable. A debugging persona that demands a reproduction before guessing. A data persona that reads numbers skeptically. A decision persona willing to say no. Each one is documented, benchmarked with eval scripts, and installable in minutes.
I built it because of what I learned running AI workflows on a real business (my mom's Shopify boutique, the Krafty Bandit project below): the failure mode of AI at work is not wrong answers, it is confident agreement. The workflows that shipped 2,861 catalog fixes in one weekend only worked because every call got checked by a human, and Candor bakes that discipline into the assistant itself. The repo includes twelve skill definitions, evals with published benchmark results, full documentation, and contribution guidelines.
It is labeled experimental (v0.5.x) and actively maintained. Free forever. It is also the companion tool for my YouTube channel, where I show the personas doing real work on a live store. github.com/itsryanlenk/candor

Today we launched Zentrik Product Loops because as our own workflow got 10x faster, it became easy to lose the reason behind the work.

A sales call became a summary. The summary became a backlog item. The item became an agent prompt. By delivery, the customer reason was hard to inspect, and what would count as proof was even harder.

Hey everyone,

As backend developers, we ve long been frustrated with managing dozens of different third-party APIs. Separate API keys, inconsistent response formats, scattered billing systems, and repeated integration work waste tons of development time.

To solve this pain point, we built AsRouter, a one-stop API aggregation gateway.

Access multiple third-party services with just one API key
