Radar vs F5Bot
F5Bot tells you the moment a keyword appears. It does not score a founder reply, draft one, or care whether the sub allows promo. That simplicity is the point — and why it has lasted. Radar is the next hour of work: which of those hits is worth your name, and what should you say. Many people should keep F5Bot and add Radar, not replace one with the other.
Radar is for
People who are drowning in alerts and want a ranked draft queue.
F5Bot is for
Anyone who wants a cheap, old, reliable ping — PR, OSS, brand, or curiosity.
I still paste every reply myself
I built Radar because Hunt plus a pasted reply on Reddit is how I actually reach people. I run it on ColorHer (photo restoration) and SHIP FM (startup radio). Radar never posts. I copy the draft, open the thread, and paste under my own name. Help-only when pitching would be spam. Founder disclosure when the product belongs in the reply.
I'm selling this because I can see it helping me get seen — and paid. OPs answer. People check the FM. A first customer showed up. I am not going to invent a round number for you.
The tools on this page that auto-post or buy accounts are a different job. I flinch at that, so Radar stops at the draft. I still paste by hand. That is the product.
The loop is public: @robsannazzaro on X.
What they have that we don't
HN and Lobsters
Three sites, not one. Radar is Reddit-only.
Free email alerts
No card. Instant, delayed, or daily digest. Slack/Discord and API on paid tiers.
Nine years of uptime story
They have been doing keyword email since 2017. Lindy applies.
What Radar holds onto
Scoring + draft
An alert is not a reply. Radar writes the first pass.
Promo rules in the draft
No-pitch communities stay help-only.
Alert vs reply
F5Bot. Know the moment. You decide what to do, and you write it.
Radar. A shortlist with copy attached. You still decide. You still paste.
Keep F5Bot if you only need to know. Add Radar if knowing without a draft is the bottleneck.
Price
Free; Silver $9.99/mo; Gold $49.99/mo (f5bot.com, checked Sep 2026).
Keep F5Bot at $0. Radar is free for your first 10 copied replies, then €19/month for the reply on top of the alert.
Their product changes. We read public pages on f5bot.com/ in September 2026 and did not sign up to every dashboard. If something here is stale, that is on us — email and we will fix it.
