6 Best Reddit Monitoring Tools in 2026
Six Reddit monitoring tools, from free keyword alerts to brand listening to written replies. Honest strengths and limits, prices as of 31 Oct 2026.
We make FounderDive, and we list it first. Every other tool here is described from its own site, checked on 31 Oct 2026. Prices change; follow the links and check before you buy.
Reddit monitoring means watching Reddit for your name, your competitors or the words your buyers use. Some tools send an alert, some build a full picture of your brand, and a few go one step further and write a reply.
We make FounderDive and list it first, but it isn't a classic monitor: it has no keyword or brand alerts. If you want alerts, Syften and F5Bot are the better picks. If you want the reply, read on.

Questions
What is the best free Reddit monitoring tool?
F5Bot. Its free plan watches 5 keywords on Reddit, Hacker News and Lobsters and sends up to 20 alerts a day.
What should a team use to monitor a brand?
Octolens or Brand24. Both cover many more sites than Reddit, and both are priced for teams: from $159 and $199 a month billed yearly (as of 31 Oct 2026).
Does FounderDive monitor Reddit?
Not in the alert sense. It looks for posts asking for what you built when you press Hunt, scores them out of 100 and writes the reply. It doesn't alert you to mentions.
Which of these tools post for you?
Most of them don't: they find posts and leave the reply, or the posting, to you. FounderDive never posts. ReplyGuy says it posts Reddit replies from accounts it bought, and Redreach's Outbound extension sends DMs in bulk. A reply from your own account is slower, and it is the one that keeps your account safe.
