Hi HN,

I built Hytale Calculator, a fan-made Chinese calculator + data hub for Hytale players. The short version: it’s the site I wish existed when I’m about to sink an entire evening into “just one more run” and realize I’m missing 17 tiny materials I should’ve planned for.

What it does

The site focuses on the unglamorous but strangely satisfying parts of sandbox RPGs:

Crafting/material calculator: pick a target item, set a quantity, and it tells you the total ingredients you’ll need (and breaks them down cleanly).

Drop expectation & probability: choose a monster / resource, set attempts, and get an estimated expected drop count (and probability where we have enough data).

Gear/stat comparisons: compare equipment stats and see the delta in a way that makes “upgrade” decisions less emotional.

Build & progression planning: rough planning tools for build choices and upgrade paths so you can prep before jumping in.

Searchable database: items, recipes, and resources are searchable so you can treat it like a lightweight reference.

It’s mobile-friendly, and supports bookmarking and sharing, because half of the time you’re looking at this stuff while someone’s yelling “go go go” in voice chat.

Why a Chinese site?

A lot of Hytale resources are English-first, and the Chinese community tends to fragment across screenshots, group chats, and scattered notes. I wanted a single place that’s:

usable in Chinese,

calculator-first (not a giant wiki wall), and

fast enough that you don’t lose your flow mid-session.

Also, I’m one of those people who actually enjoys turning messy game data into something structured. That’s either a useful skill or a cry for help.

Data & accuracy (the honest part)

The data is compiled from public community sources (wikis and guide sites) and then normalized into a consistent structure. It updates over time as sources change.

A few important notes:

This is not an official Hytale site.

Results are best-effort estimates, because community data can be incomplete, inconsistent, or outdated.

When assumptions are used (e.g., uncertain drop rates), I try to label them clearly.

If you spot incorrect numbers, missing recipes, or weird edge cases, I’d genuinely appreciate reports — the community feedback loop is the whole point.

How it’s built (briefly)

I kept it intentionally simple: structured data + fast search + a UI that stays out of your way. The “calculator” part is mostly deterministic math on top of a normalized dataset. The hard part is not the math; it’s the “please don’t let this data become spaghetti” problem.

What I’d love feedback on

Which calculator is most valuable first? (crafting vs drops vs gear vs builds)

What do you consider “must-have” filters for search?

Should sharing focus on shareable links, exportable build codes, or both?

Anything you hate about the UX on mobile?

If you’re a Hytale player (or you’ve built fan tools before), I’d love to hear what you think — especially what’s missing.

Thanks for reading, and thanks in advance for any blunt feedback.


Hi HN,

I’m an indie developer, and I wanted to share a small project I built after being repeatedly frustrated by a very specific problem: removing backgrounds from videos.

This started with something pretty mundane. I often record short videos for product demos, tutorials, or social posts. Nothing fancy — just a person or a product in front of a normal background. But every time I wanted to reuse that footage elsewhere, I hit the same wall.

The existing options felt like overkill:

Setting up a green screen just to record a 10–20 second clip.

Opening After Effects or Premiere for what should be a simple task.

Spending more time tweaking masks and edges than actually working on the content.

What bothered me most wasn’t the lack of tools — it was that the tools were optimized for editing workflows, not outcomes.

What I actually wanted was simple:

“Give me a clean cut-out video that I can reuse anywhere.”

No timelines. No keyframes. No learning curve.

So I built a website that does just one thing: You upload a video → it removes the background automatically → you download the result.

That’s it.

I made a few deliberate constraints while building it:

No requirement for a green screen.

No assumption that the user knows video editing.

No attempt to become a full video editor.

Focus on the quality of the final output, especially edges and subject separation.

In other words, I tried to optimize for time-to-usable-result, not feature count.

Right now, the tool is most useful for:

Content creators who want clean talking-head clips.

People making product or demo videos.

Educators or marketers who need reusable video assets.

Anyone who just doesn’t want to “learn video editing” to solve a small problem.

I’m sharing this here not as a big launch, but because I’m genuinely curious:

Is background removal something you deal with often?

What do you care about most in the result? (edges, speed, formats, batch support, etc.)

If you’ve tried similar tools, what annoyed you the most?

Happy to hear any feedback, criticism, or “this is not actually a problem” takes. I’ll be around in the comments.

Thanks for reading.


I’m really glad to see the positive reactions to this post! As developers, we all know how easy it is to get stuck in a routine of repetitive tasks. I’ve found that automating even small aspects of your workflow can really add up in terms of time saved.

For those of you who have already streamlined parts of your workflow, I’d love to hear what tools or strategies have worked best for you. Do you prefer using out‑of‑the‑box tools or building custom solutions? What tasks have you successfully automated, and what impact did it have on your productivity?

Looking forward to hearing your thoughts and learning from your experiences!
