Questions & Answers

As answered by people managing HTMLCSS to Image API and TGScope.io.

Which are the primary technologies used for building your product?

HTMLCSS to Image API's answer

HCTI is built with C# and .NET, using ASP.NET Core for the API and Chromium with PuppeteerSharp for browser rendering.

The rendering infrastructure combines stateful and serverless compute for speed and scalability. Cloudflare Workers sit in front of every API request, and Cloudflare provides our CDN.

The visual template editor is built with Blazor WebAssembly.

For developers integrating with HCTI, the interface is a REST API with JSON requests. Call it from any language that supports HTTP, or use one of our handwritten client libraries, built for performance. Most have zero dependencies.

TGScope.io's answer:

Next.js and React on the frontend, Python with FastAPI on the backend, PostgreSQL, Docker, and language models for topic tagging and description translation.

What makes your product unique?

HTMLCSS to Image API's answer

You design with HTML and CSS. HCTI takes care of rendering it.

Use the layout techniques, fonts, and styles you already know to generate images programmatically. A social card can use the same styling as your website. A report can pull in live application data.

Send raw HTML and CSS, capture a URL, or create a reusable template and pass in new values. The visual template editor also lets teammates work on designs without editing your application code. Images, PDFs, screenshots, and template-based graphics all run through the same API.

We've spent years working on the infrastructure side, too. Before starting HCTI, we worked on scaling very large online services at large companies. That experience shaped how we built HCTI: speed and scalability have been priorities from the start, alongside the day-to-day experience of developers using it.

We put that same attention into clear documentation, practical code examples, and an API that's straightforward to integrate. Getting your first image should be easy. Growing that integration into a production workload should be, too.

TGScope.io's answer:

TGScope combines a catalog of 3M+ public Telegram channels with original research on the platform. Beyond search and channel stats, it offers event pages that collect posts mentioning a place, company or person across channels, country-specific MTProto proxy lists, and free tools such as a channel creation date checker built on our own reverse-engineering of how Telegram assigns channel IDs. Research data is published openly.

How would you describe the primary audience of your product?

HTMLCSS to Image API's answer

HCTI is built for developers who need to generate images and PDFs as part of their product. Think social previews for every page, personalized graphics for every customer, or reports generated directly from application data.

It's a natural fit for teams that already work with HTML and CSS. You can bring your existing designs and make image generation part of your codebase without maintaining browser infrastructure.

Marketing and operations teams use HCTI, too. Reusable templates and integrations with Zapier, Make, and n8n let them generate graphics from new content, spreadsheet rows, or workflow events without asking a developer for every variation.

From a solo developer shipping a feature to a team generating images at scale, the common need is the same: turn content and data into finished visuals automatically.

TGScope.io's answer:

People looking for Telegram channels on a topic or in a language; marketers and advertisers choosing channels; journalists, researchers and OSINT investigators who need to find, check and date channels; and users in countries where Telegram is blocked who need working proxies.

Who are some of the biggest customers of your product?

TGScope.io's answer:

  • Free to use; no enterprise customers to list

What's the story behind your product?

TGScope.io's answer:

Telegram has millions of public channels but no good way to explore them: the app's own search only surfaces a handful of results. We built TGScope to index public channels at scale and make them searchable by topic, language and size. Working with that much data, we started publishing research on the Telegram ecosystem, which led to tools like the channel creation date checker.

Why should a person choose your product over its competitors?

TGScope.io's answer:

It is free and needs no account. The index is large (3M+ channels) and multilingual, with topic and language tags on every channel, so you can find niche channels in any language rather than only the biggest ones. It also covers things catalogs usually don't: what channels are saying about a given event or place, working proxies where Telegram is blocked, and when a channel was created.

  • RendrKit: The Open-Source Alternative to Bannerbear
    Bannerbear is solid. You design a template, call their API, get an image back. They're doing around $40-50K MRR, plans start at $49/mo, and they've earned it. Placid and HTMLCSStoImage do similar things in slightly different ways. - Source: dev.to / 7 months ago
