The best KWatch.io alternatives

Short answer

For Reddit, Bazzly turns the alert into a posted reply: it scores the post, drafts the answer, posts it from an aged account or yours and upvotes it. If you only need keyword alerts for Reddit, Hacker News and Lobsters, with a free plan, F5Bot is the closer like-for-like swap.

We make Bazzly, one of the tools on this page, and we list it first. Every other tool's facts come from its own site and carry the date we read them. Where another tool is the better choice, we say so, and the last section says when KWatch.io is still the right pick.

Why people look for a KWatch.io alternative

01

Alerts only

KWatch.io tells you a keyword came up on Reddit or elsewhere; every reply is yours to write and post.

02

Breadth over depth

It spreads across six platforms, so there is no Reddit-specific help: no subreddit rules, no Google-ranking threads, no upvotes.

03

Free plan is tiny

The free plan covers two Reddit and two Hacker News keywords.
