Questions & Answers

As answered by people managing OpenRouter and UtilityLab.dev.

What makes your product unique?

UtilityLab.dev's answer:

Most LLM cost calculators are either spreadsheets or require signing up for an API. AI Cost Simulator is a free, browser-based tool that works instantly — no account, no installation, no data upload. It supports the widest range of models (GPT-4o, Claude 3.5 Sonnet, Gemini 1.5 Pro, DeepSeek V4 Flash, and more) with both per-call and monthly volume estimates in one view.

Which are the primary technologies used for building your product?

UtilityLab.dev's answer:

Vanilla JavaScript, HTML, and CSS — no frameworks, no bundlers. All cost calculations happen client-side. The tool is deployed as a static site on Cloudflare Pages for global low-latency access.

Why should a person choose your product over its competitors?

UtilityLab.dev's answer:

It's the only zero-friction cost estimator. Competitors either lock features behind sign-up walls, only support one model family, or require you to dig through separate pricing pages. AI Cost Simulator gives you a side-by-side comparison of all major LLM providers in one page — and everything runs locally in your browser, so your pricing data never leaves your machine.

How would you describe the primary audience of your product?

UtilityLab.dev's answer:

Developers, indie hackers, and technical founders who are evaluating LLM APIs for their next project. Also product managers and engineering leads doing cost analysis before committing to a model provider at scale.

What's the story behind your product?

UtilityLab.dev's answer:

When building AI-powered features, we realized every model provider publishes pricing differently — per-token, per-character, per-request — and there's no single place to compare them. Instead of bookmarking five pricing pages and building a spreadsheet, we built a dead-simple comparison tool. We open-sourced the approach and made it free so other developers don't have to waste time doing manual math.

Who are some of the biggest customers of your product?

UtilityLab.dev's answer:

Since it's a free browser tool with no sign-up, we don't track individual users. It's used by developers and teams evaluating LLM costs across startups, agencies, and enterprise engineering teams.
