Changes to the data, the method and the site, newest first. Fixes to single channels are not listed; fixes that affected many channels are. How every number is calculated today is on the methodology page.

November 2026

15 November. The new TelegramInformer. The site was rebuilt from scratch, developed and tested privately before launch. Everything below replaced the original catalog in one release:

• New data collection. A new data server and crawler read every channel's public web preview daily, and the official Telegram API covers channels without a preview and gives exact repost and comment counts on larger channels. New channels are found through reposts, mentions, links and Telegram's "similar channels".
• The original catalog carried over, including subscriber history back to May 2023.
• Channel pages: subscriber chart, growth over a day, a week and a month, reach and engagement rate, ranks in category, country and language, top and recent posts, posting times, the share of posts marked as ads, views by post age, a 30-day table, and channels that repost or mention the channel.
• Rankings by category, country and language, and a country catalog: every channel is assigned the country of its audience, or "international". Category names in Russian.
• Search reads titles, usernames and descriptions, forgives typos ("durow" finds Durov) and suggests matching categories and countries.
• Content policy: adult channels are listed with an 18+ label instead of being hidden; drug sales, fraud, scams and extremist channels are kept out. See the editorial policy.
• For AI assistants: a Markdown copy of every channel, ranking and article page (add .md to the address), and llms.txt.
• New sections: Research, with Telegram statistics from our own data that update automatically, and Guides, including how to check a channel's real statistics. The outdated 2024 statistics article was replaced.
• Transparency pages: About, Methodology, Editorial policy, Terms, Privacy and Disclaimer. The site now names the person who runs it, Pavel Ufimtsev; the previously published founder profile was removed.
• Forms: a new contact form and a form to suggest a channel; suggestions are reviewed by hand.

7 November. The original site's server was stabilised before the move: repeated database crashes from running out of memory were fixed, and post collection was restored (1,011 new posts on the first run).

Before the rebuild

February 2026. The original crawler stopped collecting new posts on 13 February: it failed on deleted posts. Subscriber counts kept updating. Post collection resumed on 7 November.

2025. The original catalog's biggest year: subscriber history was recorded for about 14,600 channels.

2024. The catalog passed 9,000 channels with subscriber history. Visitors could suggest channels from June; 188 suggestions came in that year.

2023. The catalog grew from a few hundred to about 3,300 tracked channels. The earliest stored messages from the contact form date from June, and the first comments on channel pages from September.

2022. TelegramInformer was a hand-maintained catalog with subscriber history for about 560 channels. The oldest records in it go back to February 2016.
