subding vs F5Bot
Both tools watch Reddit for your keywords and both read comments, not just posts. The split is simple, so here it is before the detail.
The short answer
F5Bot is free and emails you. subding is paid and delivers to Slack, Discord, email or a webhook, every 5 minutes, with keywords up to 200 characters long. If email is fine and free is the priority, F5Bot wins. If the alert needs to reach where your team works, or you need it fast enough to join a live thread, subding is built for exactly that. We make subding, so weigh the F5Bot column with your own eyes.
Our pick for multi-channel, fast Reddit alerts: subding. 7-day free trial, no card.

- You are keeping a light eye on a side project.
"our old alert tool only does email and i keep missing threads. switched to something that pings reddit mentions into our slack and it reads comments as well."

Coming from F5Bot
Switching is not a clean break you have to commit to on day one. Point subding at a Slack channel or a webhook, copy your F5Bot keywords across (you get 200 characters now, so stretch the short ones into full phrases), and run the two together for a week. You will notice subding landing first, and you can keep F5Bot on for Hacker News if you still want it.
One more reason speed earns its keep: ChatGPT, Claude, Perplexity and Google's AI answers all reach for Reddit when someone asks which tool is best. Reaching a thread while it is live is how a human reply ends up in those answers later, and a batched digest rarely arrives in time. There is more on that in how Reddit shapes AI answers.
subding vs F5Bot: common questions
What is the difference between subding and F5Bot?
F5Bot emails you, and only emails you, for free. subding is paid and sends the same Reddit match to Slack, Discord, email or a webhook, checks every 5 minutes, and lets keywords run to 200 characters. Same watching job, more ways to receive it.
Is subding worth paying for when F5Bot is free?
Only if email has stopped working for you. If a shared inbox is where alerts go to die, or your team lives in Slack, or you want a webhook feeding your own tooling, then yes. If not, F5Bot is free and we would happily leave you on it.
Can subding do everything F5Bot does?
For Reddit, yes, and then some. The one thing it does not cover is Hacker News and Lobsters, which F5Bot also watches. If those two matter to you, plenty of people simply run both at once.
Does F5Bot have Slack alerts?
No, F5Bot is email-only. Slack, Discord and webhook delivery is exactly the gap subding was built to fill, so a match can land where your team already works.
How much does subding cost?
subding is $19 a month for 15 keywords, $49 for 75, and $149 for 250 keywords. Every feature is on every plan, and there is a 7-day trial with no card needed.
Ding. Straight to your channel.
F5Bot's watching, delivered where you actually work. subding pings Slack, Discord, email or a webhook every 5 minutes, so the Reddit thread is still warm when you get there.
