F5Bot alternatives

What F5Bot is

F5Bot watches Reddit, Hacker News and Lobsters for the keywords you choose and sends you an alert when one appears in a new post or comment. Its site says it checks every few minutes and emails alerts instantly, on a delay or as a daily digest.

When we checked, the free plan covered keyword alerts on all three sites with email notifications, and was described as free forever with no card. Silver, at $9.99 a month, added 20 keywords, advanced filters and full post text; Gold, at $49.99 a month, added 200 keywords, RSS and JSON feeds, AI filtering and Slack and Discord.

Why people look for an alternative

F5Bot does one job, alerts on exact keywords, and does it cheaply. People look elsewhere when they need something it isn't built for: more places than Reddit, Hacker News and Lobsters; smarter matching than keywords, which miss posts that describe a problem in other words; or help with what comes after the alert, such as replying, ranking pain points or testing an idea.

Keyword alerts also arrive one at a time. If you're trying to decide whether to build something, a stream of individual mentions is harder to read than a set of posts gathered around your idea.

The alternatives, one by one

Syften

The closest step up: alerts like F5Bot's, across many more places, including Reddit, X, Indie Hackers, Hacker News, GitHub, Product Hunt, Stack Exchange, forums, newsletters and the wider web. Plans run from $29.95 to $119.95 a month, with a 14-day free trial of the top plan and no card needed.

Brand24

A full social listening tool for brands: it monitors social networks, Reddit, news, blogs, reviews, YouTube, TikTok and podcasts, and adds analysis on top. It's priced for companies, from $199 a month billed yearly ($249 monthly), with a 14-day free trial and no card.

Redreach

Built for one job: finding Reddit threads where people ask for product recommendations, often ones that rank on Google, and suggesting replies you post from your own account. Its site lists plans by number of seats and a paid 3-day pass, without plan prices on the page.

PainOnSocial

Instead of alerts, it scans subreddits you choose over 7, 30 or 90 days and ranks the pain points that keep coming up, with quotes and links. Starter is $19 a month after a 7-day trial.

Ghostlaunch's free search

We make this one. Rather than matching keywords, describe your idea: it works out the words people use for the problem, searches Reddit's past week and shows up to 10 posts that match strongly, with links. It's free with no sign-up, and Ghostlaunch can then run a 7-day landing page test for the idea.

How to choose

If F5Bot's three sites and exact keywords are enough, keep using it: the free plan is hard to beat. If you need more places, Syften is the natural next step, and Brand24 suits a company that needs listening across social media with reports for a team.

If the alerts are for a specific job, pick the tool built for it. Redreach is for replying to people asking for recommendations; PainOnSocial is for finding problems worth solving. And if you're watching Reddit to decide whether to build something, a set of posts gathered around your idea is easier to judge than a stream of mentions. That's what Ghostlaunch's free search shows.
