The best anti-spam bot for Telegram depends on what kind of spam you actually have. Bulk bot joins and link floods are a permissions and captcha problem, and free rules bots handle them well. Reworded scams, fake admins and DM hunters are a detection problem, and no keyword filter catches them. This list is split that way on purpose.

We build collony.ai, an AI moderation bot for Telegram, so we have an obvious interest. Same rules as our broader Telegram bot ranking: honest strengths, named gaps, and a competitor ahead of us wherever it earns it.

What an anti-spam bot actually needs to do

Three jobs. Gate the door: captcha, account-age and join-rate checks so farms cannot pour in. Filter the obvious: links, forwards, flood, banned words. Detect the rest: the account that passes every gate, posts a clean-looking message and pivots to a scam. Most bots do the first two. Almost none do the third, and the third is where communities actually get hurt, which our 2026 security report measured at 85.7 percent of scam messages carrying no blocklisted keyword at all.

The best Telegram anti-spam bots in 2026

1. collony.ai: best for scam and behavioral spam

collony watches behavior instead of words: first-message timing, link destination, sender history across communities, impersonation of admins. It catches the reworded giveaway, the fake support account and the slow-burn DM hunter that pattern filters wave through, and removes them in seconds. It is built to run next to a rules bot, not instead of one, and it is the only entry here that is not free, priced per community with a trial.

2. Rose: best free rules and captcha bot

Rose is the default for a reason: free, mature, and deep on filters, warns, welcome captcha and federations for shared ban lists. It is the strongest free rules layer on Telegram, and its blind spot is the same as every rules bot, anything a spammer rewords. Full breakdown in our Rose alternatives guide.

3. Shieldy: best pure join gate

Shieldy does one thing, a captcha challenge on join, and does it simply. If your only problem is bots joining in bulk, it is the lightest fix available. It does nothing about spam from accounts that are already inside.

4. Combot: best when you want analytics with your filters

Combot bundles solid anti-spam rules with the best analytics dashboard on Telegram, which makes it the pick for managers who report on the community. Its filters are rules-based with the usual gaps, covered in our Combot review.

5. GroupHelp: best free all-rounder for smaller groups

GroupHelp covers captcha, anti-flood, link and media filters and welcome messages in one free bot with a menu-driven setup that is friendlier than Rose's commands. It is a good first bot for a group under a few thousand members, and it hits the same ceiling as the other rules bots once scammers start adapting.

How to choose

• Bulk bot joins: Shieldy or Rose captcha, plus the join settings in our anti-spam checklist.

• Link floods: Rose or GroupHelp filters, with the link permissions from our link-blocking guide.

• Scams that keep getting through: add collony on top of whichever rules bot you run.

• Reporting to a team: Combot.

Frequently asked questions

What is the best anti-spam bot for Telegram?

For scam and behavioral spam, collony.ai, because it reads what accounts do rather than matching words. For a free rules-based filter with captcha, Rose. For join-time bot blocking alone, Shieldy. Most serious groups run a rules bot plus a detection layer.

Is there a free Telegram anti-spam bot?

Yes. Rose, Shieldy and GroupHelp all have free tiers that cover captcha gates, link filters and basic flood control. The free tiers stop low-effort spam. Reworded scams and impersonation need detection that is not free anywhere.

Can a Telegram bot stop spam in DMs?

No bot can read or block private messages sent to your members. What a bot can do is stop the accounts that DM-hunt from joining or staying in the group, by gating joins and removing accounts that show scam behavior before they reach members.

Do I still need anti-spam settings if I install a bot?

Yes. Telegram's own permissions, slow mode and join approval are the floor that bots build on. A bot without those settings works harder and catches less. Set the native controls first, then add the bot.
