Context
The client ran a large network of source Telegram channels and chats that had to be replicated into another ecosystem. Standard forwarding wasn’t enough: posts needed to keep media and formatting while rewriting links away from the original infrastructure. Manual publishing across 100+ sources and destinations wasn’t viable.
03 / Product
Product
A high-load Telegram→Telegram and Telegram→Discord replication system. It ingests posts, processes text, formatting, attachments and metadata, then recreates full copies in destination channels—not a forward that exposes the original.
- channel/chat/message mapping with internal link rewriting;
- per-route customisation: signatures, aliases, text edits;
- Discord adapter for formatting, albums and attachments;
- parallel processing, retries, dedupe and API rate-limit handling.
04 / How it works
How it works
Each source channel or chat is mapped to a Telegram or Discord destination. New posts are parsed into text, entities, media, albums and replies; the system creates an independent message in the target. Links to source channels, chats and posts are replaced with their counterparts in the replica.
One source post can look different on different routes. A failure or heavy file on one path doesn’t block the rest.
05 / Navigation and scale
Navigation and scale
The key is keeping internal navigation: users stay in the target ecosystem instead of leaking back via broken or original links. Channel, chat and message mappings live in PostgreSQL; the architecture is built for 100+ channels and heavy media volume.
06 / Outcome
Outcome
Automated sync for an ecosystem of 100+ channels and chats: not just posts, but navigation logic too. Manual copying and broken links go away—the replica can evolve independently of the source.
07 / Uptime and support
Uptime and support
The system runs at 100% uptime: replication and mapping must not take the client’s content loop down with them. We maintain the infrastructure—monitoring, updates, API incident handling, retries and long-term route stability.
