How We Built a High-Performance Telegram Engine and Scaled to 1,100+ Users Organically

What’s the most frustrating thing about Telegram automation? For me, it was latency. When you are building tools for high-load scenarios—like username marketplaces or real-time monitoring—every millisecond counts.

Standard bot wrappers are great for simple tasks, but they often fail to handle the overhead when sub-second execution is a requirement. That’s why we decided to build Flashgram.

The Problem: The "Latency Tax"
Most existing Telegram tools are built on top of inefficient request handlers. While they work for 90% of cases, the remaining 10% (power users) suffer from delays that can break a business model. We wanted to eliminate this "latency tax" by optimizing how we interact with the MTProto protocol.

Our Approach: Performance Over Fluff
We are a small team based in Dnipro, Ukraine. Instead of spending months on a fancy UI, we focused 100% on the core engine. We wanted a tool that we would actually want to use.

Key Technical Focuses:

Concurrency: Managing thousands of requests without hitting local CPU bottlenecks.

Rate-Limit Navigation: Finding that sweet spot between maximum speed and Telegram’s API constraints.

Reliability: Ensuring the engine stays stable during peak market volatility.

Scaling to 1,100+ Users with $0 Marketing
We didn't have a marketing budget, so we chose the "Developer-to-Developer" path. We shared our technical milestones, discussed our bottlenecks openly, and invited people to try out the engine.

The results? 1,100+ active users joined our community purely through word-of-mouth and technical discussions on dev forums. People don't want more ads; they want tools that actually work faster than what’s currently on the market.

Building in Public
We believe in transparency. My team—myself (@fuckobj) and our deputy lead (@Who_realerr)—is constantly iterating based on community feedback.

If you are a dev working within the Telegram ecosystem, I'd love to hear your thoughts on optimization and what features you’d like to see in a high-speed automation engine.
