How to choose a Discord bot for your server
"Which is the best Discord bot" has no general answer, because servers do not have the same needs. It has one as soon as you restate it as five criteria.
This guide lists them, including the ones where this site does not have the advantage.
1. Scope, and how many bots you end up adding
A bot covering moderation, levels, welcome and alerts saves you from running four. That matters more than it looks: each extra bot adds a configuration to maintain, a role hierarchy to arbitrate, and a point of failure.
Conversely, a specialised bot usually does better on its own ground than a generalist. The practical rule: a generalist for the base, a specialist only where the need is genuinely sharp.
2. The pricing model
Many widely used bots place behind a subscription the features you discover to be essential afterwards — message customisation, the number of automatic roles, alert frequency.
Check this before configuring the server, not after: migrating a levelling system from one bot to another loses every member's accumulated progression, which is what makes the initial choice hard to reverse.
3. Data handling
A moderation bot reads your server's message content. Two questions to ask: is that content stored, and is it used to train a model?
The answer belongs in an accessible privacy policy. Its absence is itself a signal, as is a policy that stays vague about retention or about how to request deletion.
4. Language
A bot whose messages, errors and documentation are English-only works poorly on a server where part of the membership does not read English. The point shows up less in the commands than in the automatic messages: welcome, warnings, permission refusals.
Eric runs in French and English, chosen per server, including for the names of some commands.
5. What a server count does not tell you
Bots readily advertise a seven-figure server count. That figure measures past visibility and ease of adding, not the quality of the service: a bot added and then forgotten counts as much as one in active use.
The useful indicators are elsewhere: support response time, update frequency, and whether there is a help server where you can see how problems are actually handled.
