TGScope.io VS HTMLCSS to Image API

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.

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

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.

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

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.

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

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.

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.
