The F5Bot alternative that does the work.
F5Bot is a great free utility — it emails you when your keyword shows up on Reddit. But an alert isn't a lead: it can't tell you who's a buyer, read the thread, or write the reply. Prowlify does all of that, through your own account.

Great free alerts. But an alert isn't a lead.
F5Bot does one thing well and for free: it watches Reddit (plus Hacker News and Lobste.rs) for your keywords and emails you when one appears. For a simple heads-up, it’s hard to beat.
But it stops at the ping. It matches a word, not intent — so it can’t tell a ready-to-buy question from someone just saying the word, it doesn’t read the thread for context, and at any real volume the emails become noise you triage by hand. The reading, qualifying and replying are all still on you.
F5Bot tells you someone said the word. It can’t tell you whether they want to buy.
From keyword ping to qualified, drafted lead.
Prowlify doesn’t just match a word. It reads the whole thread, scores it for buying intent, filters out the noise, and drafts a reply in your own writing voice — then waits for you to approve, edit or skip.
And it goes past Reddit: it runs real market research across a niche, sends DMs, watches the inbox, and can cover LinkedIn and X too — all through your own logged-in accounts, at human pace.
The bigger difference is how you use it: you don’t operate a dashboard, you just talk to one agent — part community regular, part marketing team. Tell it what you sell and it researches the niche, finds and scores leads, drafts in your voice, and posts on approval — no manual, reply-by-reply work. It goes deep on Reddit, and can run LinkedIn and X the same way, coordinated as one Squad when you want all three.
Honest note: no tool can promise zero risk on Reddit — anyone using the platform takes some. The difference is staying in control of every action and not being exposed to the same dependency that took the others down.
