Ask HN: What apps are you building?

8•totaldude87•1h ago
I’m curious what people here are working on lately.

What are you building right now?

Apps, tools, experiments, weird side projects, anything. Would love to see what folks are making.

We are building an AI Agent Designer web app-Craftsman Agent which can turn prompts into ready to use 3D/2D design, such as a Tesla car wrap, a Perler Beads Pattern, etc. You can use "Generate a blue and white yacht", "Generate a Argentina Football Team Theme Car wrap or Perler Beads Pattern" to generate lego 3D blueprint, step by step assembly charts, etc.

I have created a whitelist only email service at Supertopsecret.com. Only addresses the user provides can get into the inbox. All else is blocked. Landing page is a spy theme and would be interested if people think it's too sarcastic/off putting. Thank you. Detailed comments can go to hq@supertopsecret.com (which I set up to be non-whitelist only).

I built a mini frontend framework with components, state management and backend data fetching.

It is designed to have a minimal learning curve, and has faster performance than React due to the use of web components.

For my Indian folks, I have just yesterday launched 100% free railway API. Truly free, no strings attached.

The rate-limits are good enough that you can build automations on top. It also comes with MCP server.

The API is open to all, not just in India. Feel free to use.

I'm building a writing app for perfectionists: Reproof (https://reproof.app/)

I've been a writer for over a decade and a half. I'll often rewrite intros and other sections a half-dozen times, or cut quotes and bits that don't quite fit, only later to wonder if an earlier take was better.

I built Reproof to solve this. Every paragraph is versioned, so you can rewrite paragraphs and switch between the takes to see which sounds better. There's a clipping pane on the bottom, to cut things and save them just in case you find a spot to include them later. And there are a bunch of writer-focused features: Write and copy text in either rich text or Markdown, open two documents side-by-side and find/replace between both, selective find/replace to edit only some of the results, command palette to search across everything, daily versioned backups, and more. And lots more to come.

Nearly every other writing app is a digital piece of paper with linear paragraphs. Reproof instead lets you explore the best way to write what you're trying to say.

Working on a rewrite of my free app, Post Haste. The idea is that you setup a template folder structure and configure project files and such as you like, then when you want to create a new project you enter some parameters like project name and ID and it copies the structure across.

There’s more to it than that of course, and you can use variables, folder breaks, etc, to fully customize how it sets up the project.

It’s great for ensuring consistency in project structures, which is especially useful in a larger company with a lot of employees. It was originally created for video editors but it’s agnostic and can be used for any type of project.

Existing app is here: https://www.digitalrebellion.com/posthaste
